Dr. Christopher Case (of Oxford PV) Discusses Game-Changing Future Transformer of Solar Power Generation-Perovskite Based Solar Cell Technology

Share

Dear Friends, Visitors/Viewers/Readers,


(Please click on red links & note magenta)

I  saved the most potential game-changing solar technology in the last interview spot, the update of Perovskite-based solar cell technology with the Chief Technology Officer of Oxford PV, Dr. Christopher Case, of this series of Intersolar North America 2015 interviews. Recalling one of our earlier posts, I wrote about Perovskite, a calcium titanium oxide mineral discovered in the Ural Mountains of Russia in 1839. This new old material is generating quite an explosive buzz because scientists have found, in recent years, that it is a great material to be used in solar absorption applications. It can be made simply and inexpensively by using common wet chemistry lab methods and low cost equipments instead of the expensive deposition equipments common in the semiconductor industry. To take a look at how this process is made cheap and accessible, I’m sharing the video below:


These solar (photovoltaic) cells are made in tandem (layer by layer) fashion on a specially coated glass support. In the video above:

  1. the glass is coated with a dense layer of titanium dioxide, by robotic arm, to prevent electrical charge generated by sunlight from leaking out of the cell.
  2. a less dense porous oxide layer covers the dense oxide layer (usually titanium dioxide, other oxides may also be used).
  3. a simple high speed spin coater deposits this layer from solution and spreads this coating evenly across the device.
  4. heating this glass/device in an oven conditions it for solar cell use.
  5. prepare the Perovskite material (which absorbs in the broad range of solar spectrum) by combining 2 precursor materials:   PbI2 (lead iodide) & CH6IN (methylammonium iodide)
  6. drip the liquid phase mixture (from 5.) onto the oxide coated device (from 4.)
  7.  spin the resulting device in 6 to assure even coating
  8.  applying halide solution
  9.  heating the device resulting from 8 on a hot plate–>spontaneously crystallizes precursors in freshly deposited liquid
  10.  color changes also result from crystallization process resulting from 9.

Such tandem product has the advantage of being able to be introduced into existing infrastructure of current silicon module manufacturing process, boosting its efficiency. With added few steps toward the end of the production line, the coating (equivalent to second solar cell) takes advantage of the blue portion of the solar spectrum and may improve the solar cell efficiency by 20-25% above the underlying silicon. The fact that Perovskite-based solar cell technology is of earth abundant material also insures its availability and low cost. Its high absorption in solar spectrum enables it to have comparable characteristics to that of gallium arsenide. Its ability to change its sensitivity to different band gaps in solar spectrum allows it to make different architectures in tandem solar cells. It can truly be considered as the Custom Solar Absorber! In short term,  Perovskite-based solar cell may boost the efficiency level of existing technology and in the long term, it may be a stand-alone technology with closer efficiency level to that of gallium arsenide but at a much lower cost. It may potentially be sprayed, ink-jet printed, dip-coated, etc. It is no wonder that Dr. Case commented, “the perovskite in solar application is the fastest increasing photovoltaic efficiency of any solar photovoltaic thin film material ever! In just a few years, it went from a lab efficiency of about 6% to well over 17%…the material is a very good solar absorber….bringing the material to 25% efficiency in a monolithic layer and 30%+ in a perovskite tandem layer….potentially the future replacement for silicon.”

The perovskite thin-film solar cells, is currently being developed by Oxford PV (a spin-out from the University of Oxford in 2009-2010 to commercialize this technology, which has exclusively licensed the intellectual property developed by Professor Henry Snaith and his team of 20 scientists). Below, Professor Henry Snaith will embellish upon the development of this solar technology:

Oxford PV plans on continuing to optimize this technology’s cell efficiency and accelerate the transfer of the technology into production. Furthermore, it aims to develop the range of substrates to which the cells can be applied. With its promising future, we, the solar enthusiasts and investors alike, should keep our eyes on Oxford PV in the coming years. In the next few years, we anticipate that Dr. Henry Snaith and his team of scientists will continue to tackle challenges in trap densities, doping densities, mobility, mechanisms for free carrier generations, etc., to further improve device performance. You will find that many in the solar industry share the optimism of Professor Henry Snaith and Dr. Christopher Case.

The Unsung Hero of Civilization, UL, Underwriters Laboratories, at Intersolar North America 2015

Share

Dear Friends, Visitors/Viewers/Readers,

UL logo (Underwriters Laboratories)

UL logo (Underwriters Laboratories)

(Please click on red links & note magenta)

UL, Underwriters Laboratories, is an American worldwide safety consulting and certification company headquartered in Northbrook, Illinois. It maintains offices in 46 countries. UL was established in 1894 and has participated in the safety analysis of many of the last century’s new technologies, most notably the public adoption of electricity and the drafting of safety standards for electrical devices and components. UL provides safety-related certification, validation, testing, inspection, auditing, advising and training services to a wide range of clients, including manufacturers, retailers, policymakers, regulators, service companies, and consumers. UL is one of several companies approved to perform safety testing by the US federal agency Occupational Safety and Health Administration (OSHA). OSHA maintains a list of approved testing laboratories, which are known as Nationally Recognized Testing Laboratories. Above is a recording of a short chat with Tony Dorta of UL.

Some historical backgrounds regarding UL, with the help of Wikipedia, below (in Italics):

Underwriters Laboratories Inc. was founded in 1894 by William Henry Merrill. Early in his career as an electrical engineer in Boston, a 25-year-old Merrill was sent to investigate the World Fair’s Palace of Electricity. Upon seeing a growing potential in his field, Merrill stayed in Chicago to found Underwriters Laboratories. Merrill soon went to work developing standards, launching tests, designing equipment and uncovering hazards. Aside from his work at UL, Merrill served as the National Fire Protection Association’s secretary-treasurer (1903–1909) and president (1910–1912) and was an active member of the Chicago Board and Union Committee. In 1916, Merrill became UL’s first president. UL published its first standard, “Tin Clad Fire Doors,” in 1903. The following year, the UL Mark made its debut with the labeling of a fire extinguisher. In 1905, UL established a Label Service for certain product categories that require more frequent inspections. UL inspectors conducted the first factory inspections on labeled products at manufacturers’ facilities—a practice that remains a hallmark of UL’s testing and certification program. UL has expanded into an organization with 64 Laboratories, testing and certification facilities serving customers in 104 countries. It has also evolved from its roots in electrical and fire safety to address broader safety issues, such as hazardous substances, water quality, food safety, performance testing, safety and compliance education and environmental sustainability. In 2012, UL transformed from a non-profit company into a for-profit corporation.

The video below is about a multi-tasking solar module system, R-Volt, by a French company SystoviM. Ludovic Baudry explains this clean and conserving solar module system during Intersolar North America 2015, at Moscone Center of San Francisco, CA, in July of 2015. As indicated in the above diagram, there is an extra layer of air gap that would allow forced air through to utilize the heat generated from the solar cells under the sun to heat up the house while boosting the solar cell efficiency by reducing the heat on the solar cells (henceforth, aerovoltaic). This rather smart and efficient design of generating electricity-heating up the house-boosting solar cell efficiency simultaneously would be particularly welcomed in colder climate regions.

Helios Solar Works’ BIPV at Intersolar North America 2015

Share

Dear Friends, Visitors/Viewers/Readers,


(Please click on red links & note magenta)

As I strolled through isles of products being exhibited at Intersolar North America 2015, one BIPV (building-integrated photovoltaics) company, Helios Solar Works caught my attention, above, with the CEO (Chief Executive Officer) of Helios Solar Works Steven Ostrenga.This BIPV module system is a monocrystalline, 200 watt module system that may sit on top of or be integrated into the rooftop, waterproof, with integrated frame and 25 year warrenty period. This BIPV module system is lighter, easier to maintain, less ventilation or leakage issue, and aesthetically more pleasing than the traditional rooftop PV.

As it turned out, Helios Solar Works LLC was Milwaukee’s first solar module manufacturing facility that has helped to create many local full-time and part-time jobs for the local economy. Definitely, automation has also played a significant part behind the success of Helios.The founding of the company was based around some basic tenets: such as solar electricity is essential for nation’s energy security, environment, and economy.  It is currently engaged in research, development, sales and services of solar panels and PV systems, supplying products to more than 60 countries (such as Germany, Spain, Italy, America, Canada, Korea, Japan, China, etc.) and five continents. Their products are used in residential as well as in commercial and industrial solar power systems, PV power stations and many other areas. As the company expands and reorganizes, it is now located in 632 College Drive, McDowell County, North Carolina. As companies expand globally, it becomes even more important for business leaders to appreciate the concept of economic interdependence in order to operate optimally.

Aquion Energy, A Low-Cost, Safe, and Clean Battery System

Share

Dear Friends, Visitors/Viewers/Readers,


(Please click on red links & note magenta)

I want to make sure that you are all aware of this particular technology before moving on to another topic, for Aquion Energy has a saltwater electrolytes-based technology that provides a low cost and safe way to store large amounts of energy (e.g. for an electricity grid) through thousands of battery cycles and a non-HAZMAT end product. It operates safely and reliably in a wide range of temperatures and environments. It is also the only one that is cradle-to-cradle certifiedAquion Energy is a Pittsburgh-based company that manufactures sodium ion batteries and energy storage systems.

Below, is a bit of history and background about the company (from wikipedia):

The company was founded in 2008 by Professor Jay Whitacre, a professor at Carnegie Mellon University, and Ted Wiley, setting up research and development offices in Lawrenceville, where it produced pilot-stage batteries. The company claims to have raised funding from Kleiner Perkins, Foundation Capital, Bill Gates, Nick and Jobey Pritzker, Bright Capital, and Advanced Technology Ventures, among others. The company was the corporate winner in the energy category at the 2011 World Technology Awards. In 2015, the company announced that it would supply batteries for a Hawaii microgrid to serve as backup for a 176-kilowatt solar panel array. The system will store 1,000 kilowatt-hours of electricity.

Below, I want to share with you a presentation by Professor Jay Whitacre at TEDxCMU2012, to have a better understanding of the make-up behind this energy storage technology ( recommended):


The ambient-temperature battery is designed for storage for wind and solar power. According to the company, it will be 85 percent efficient. The battery uses non-toxic materials. The cathode uses manganese oxide and relies on intercalation reactions. In its earlier days, Aquion used an anode made of carbon which relies mostly on pseudocapacitance to store charge resulting in a low energy-density and a tilted voltage-charge slope. Later, Aquion switched to a titanium phosphate (NaTi2(PO4)3 )  anode which is a true intercalation material with a large specific charge (Ah/kg) and a flat voltage-charge slope. In many ways, titanium phosphate is similar to iron phosphate used in A123 batteries, but with a low (anodic) electrode potential. The electrolyte disclosed in earlier patent applications was an aqueous sodium sulphate solution, in later a more soluble <5M NaClO4 has been used. A synthetic cotton separator was reported. It is worth noting that Aquion targets stationary electric energy storage markets with long runtimes (such as peak shift and renewable energy storage) which requires the use of unusually thick (>2 mm) battery electrode layers, which leads to a trade off in power density. An individual battery stack will store 1.5 kWh, a pallet-sized unit 180 and a shipping-container-size box holds 2.88 MWh. The battery cannot overheat. Aquion has yet to divulge precise functional details.

The company expects its products to last for more than 3,000 charge/discharge cycles while retaining 80% of starting capacity, twice as long as lead-acid batteries but with a lower power density than other technologies. Costs are expected to be about the same as with lead-acid. In October 2013 they announced a memorandum of understanding with Siemens to adopt their power inverter technology. In October 2014 they announced the new generation of their battery that has a 40 percent increase in energy density (whilst staying the same size), a stack of the battery stores 2.4 kWh and a module (several stacks joined together) 25.5 kWh

What I’ve learned from the video above: true cost driver of Aquion battery is the separator; it’s helpful to use a prop (such as a t-shirt) at fundraising demo. Below, is another video on more details of this grid energy storage, beyond batteries, of Aquion Energy, presented at VLAB, examining the technology and economics behind this product (much worthwhile advices), starting from 17:00:

Sonnenbatterie, Energy Storage Company With the Fully Integrated System & Great Potential

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links & note magenta)

Those of us who have been following the solar industry for quite a few years/decades realize that reliable Energy Storage holds the key to Solar Energy Future. Therefore, it is not surprising that Intersolar North America 2015 placed a great deal of emphasis on the topic of Energy Storage-Battery Technology. The simple fact that the sun does not shine 24/7/365 necessitates reliable energy storage before solar energy can truly become mainstream. Important factors when choosing the energy storage system are: reliability, capacity, durability, and safety. With Tesla’s Powerwall and Powerpack being in the news much lately, I was curious about the energy storage systems being introduced by Sonnenbatterie,

a German company that has been a leader for energy storage in Europe for many years.

Sonnenbatterie Manufacturing storage system (credit: Sonnenbatterie)

For the first time, Sonnenbatterie is entering the North American market and is the winner of  Bloomberg Pioneers Award 2015. I had the opportunity to chat with US management/CEO of Sonnenbatterie, Boris Von Bormann, about features that distinguish Sonnenbatterie’s units from Tesla’s Powerwall or Powerpack: Sonnenbatterie has a fully integrated (battery+inverter) system and can be taken apart whereas Tesla’s Powerwall or Powerpack contains only the battery system. In the age of collaboration, it would be great if Sonnenbatterie would also develop an inverter system that will work with Tesla’s battery technology. Sonnenbatterie’s system can also be integrated with the utility so to be more efficiently managed. The intelligent storage solution has a built-in smart meter

Sonnenbatterie touch display (credit: Sonnenbatterie)

that enables the management of local energy production and consumption. By using a mobile app the houseowner decides whether to feed-in or directly consume the homemade electricity. Without further ado, let’s hear what Boris Von Bormann has in store for us, below:

I’d also like to share with you, another video, with Sonnenbatterie’s Christoph Ostermann, at Ecosummit 2013, below.  Sonnenbatterie is a true pioneer for Sonnenbatterie started selling their system prior to the existence of either supply or demand for the market/system. Within two years of its inception, Sonnenbatterie was able to sell 1500 systems. The growth continued, with about 8,000 systems sold in Germany by Spring of 2015 and production running at about 100-150 systems per week. At ECO13, Sonnenbatterie won the Ecosummit Award Jury Bronze medal in recognition of their outstanding business potential.

With the anticipated upcoming Solar Tsunami, it will be well worth the effort for investors and consumers in the solar energy market to keep an eye on Sonnenbatterie, for it has a fully integrated system and it can fill consumers’ order this year.

Recently, Sonnenbatterie has partnered with Outback Power to integrate their smart energy storage solutions with a trusted inverter for residential solar customers across North America. Historically, Outback Power has been a leading designer and manufacturer of advanced power electronics for renewable energy, backup power, and mobile applications. “OutBack Power’s Radian inverter/charger was a natural choice to integrate into Sonnenbatterie’s eco residential smart storage system,” said Boris von Bormann, CEO of Sonnenbatterie USA. “Working with OutBack, we are confident we can provide American home owners with the peace of mind our European customers have come to expect from Sonnenbatterie — that their home energy storage system will operate reliably in any environment and applications.” For a look of Outback Power’s Radian Series, in the video below:

Exciting Coming Renewable Decade-Opening Ceremony at Intersolar North America 2015

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links & note magenta)

Allow me to share with you some of the golden nuggets (above) during opening ceremony of Intersolar North America 2015:  It is both heart warming and energizing to hear the opening speech by Prof./Dr. Eicke R. Weber, the Intersolar North America Conference Chairman and Director of Fraunhofer Institute for Solar Energy Systems (ISE) at Intersolar North America 2015, in Intercontinental Hotel.  Prof. Weber’s speech is full of good news. Besides mentioning the necessity of renewable energy source, its cost trending downward toward 2-4 cents per kWh and much more improved energy storages becoming commercially available on the market, Prof. Weber also reminds us that PV is currently at its infancy, equivalent to the automotive sector back in 1920’s, with much exciting growth to come in the coming decade. Chief Technology Officer and Co-Founder of Tesla Motors, J.B. Straubel, further supports this view, adding the synergy between PV, renewables, and cars, and achieving sustainability with transportation. In order to achieve this, it is important not just to make electric vehicles but to make sure that these electric vehicles are linked back to renewable energy sources.There is much similarity between the PV and e-vehicle markets, both have dropped in cost and will eventually be dominating its respective markets (PV in the energy market and e-vehicle in transportation market). It is truly exciting to be at the beginning of the cost-decline curve, for PV to be within grasping distance of the goal of being cheaper than fossil energy. Such a tipping point is anticipated to occur within the coming decade. Yes, sensation of excitement is palpable in the room. I felt as though surrounded by a room full of soldiers, rearing to go.

At this point, I’d like to present two charts: 1. Global Annual PV Market Until 2017 (Sourc: EPIA) 2. Global Revenues of PV Energy Storage, in Billion US$ (Source: IHS Inc.), below:

Global Annual PV Market Between 2013-2017 (Source: EPIA) made available by sunisthefuture.net

Global Revenues for PV Energy Storage (Source: IHS Inc.) chart made available by sunisthefuture.net

Continuing on, the Executive Director of CALSEIA (California Solar Energy Industries Association) Bernadette Del Chiaro, points out that the 3 gigawatts of solar installations within the past 3 months in CA is largely responsible for combating the shortfall of hydroelecric output resulting from CA draught (recall 25% of the CA energy/power comes from hydroelectric power, currently down 25-50% due to CA draught). So, definitely applause is in order for the unsung hero of solar PV!  It is terrific to hear the statistics on “every 3 minutes, some one in CA is going Solar“. Director Del Chiaro also reminded the audience the importance of SAVE The ITC (Investmnet Tax Credit) campaign. Then we come to New York Senator Kevin S. Parker, citing more exponential growth data of solar installations and the New York -Sun Initiative, with ambitious goal of 3 gigawatts of solar installations in the coming decade. He further states that he is looking for opportunities of partnerships with various groups for large scale renewables as the state of New York continues to walk toward the Sun. More on Intersolar North America 2015 and storing the sun, below, with Kilian Reichert:

Also, it is important for the world to learn from CA, to encourage the right kind of policy to be instituted so to encourage the growth of solar and renewable energy. During Intersolar North America 2015, we’d like to share some thoughts from the Champion of Change Award winner, former state assemblywoman Nancy Skinner, who was instrumental in introducing the mandate of 33% of the electricity generated from CA to be coming from renewable sources such as solar. She is in support of policy that would encourage renewable sources for both distributed as well as utility scale generation. Our hats off to Nancy Skinner! I believe such mandate would benefit all states of USA. More, below….

Intersolar North America 2015, In San Francisco, With Intention

Share

Dear Friends, Visitors/Viewers/Readers,

Permanent art installations from Janet Echelman, Kendall Buster, Norie Sato, Charles Sowers, and Walter Kitundu of San Francisco (SFO) international terminal in Terminal 2, formerly known as the "Central Terminal" replaced Rotunda A as SFO's international terminal in 1983. (photographed by sunisthefuture-Susan Sun Nunamaker)

Permanent art installations from Janet Echelman, Kendall Buster, Norie Sato, Charles Sowers, and Walter Kitundu of San Francisco (SFO) international terminal in Terminal 2, formerly known as the “Central Terminal” replaced Rotunda A as SFO’s international terminal in 1983. (photographed by sunisthefuture-Susan Sun Nunamaker)

(Please click on red links & note magenta)

Of all the photos I took during the trip to Intersolar North America at San Francisco, CA, I find this one (above) truly reflects the spirit of San Francisco. Take a look at how this piece of sculpture by Janet Echelman is described in wikipedia:

Echelman transforms the terminal with fictional nature that subtly engages viewers with real and imagined natural forces. Her sculpture installation cuts three round skylights into the ceiling, from which descend delicate layers of translucent colored netting to create three voluptuous volumetric forms. A series of shaded outlines below are embedded into the terrazzo floor, reflecting the precise shadows that would occur on the summer solstice if the sun could penetrate through the roof. During the day, sun streams through the skylights to cast real shadows that interplay with the fictional shadows in the floor. At night, the artist’s program of colored lighting makes the sculpture glow from indigo to purple, magenta to red-orange. Computer-programmed mechanized air-flow animates the fluidly-moving sculpture at different intervals throughout the day, as if the wind could magically flow through solid walls.

The artist achieved the sculpture’s physical presence by braiding fibers and knotting twine into sculptural netting suspended from powder-coated steel armatures. Despite their large scale, more than 120 feet in circumference for a single form, her sculpture is experienced as ephemeral and weightless. Visually, the sculpture evokes the contours and colors of cloud formations over the Bay and hints at the silhouette of the Golden Gate Bridge. Aesthetically, the sculpture looks both backwards and forwards, drawing its color from the heyday of psychedelic music, the Summer of Love, and San Francisco’s prominence in the beat poetry movement, while also referencing the contemporary bay area as a hub of innovation and interconnectivity for the world of technology.

There is definite intention behind how and why San Francisco is such a hub of innovation and interconnectivity for the world of technology. I have personally observed, on more than one occasion, how San Francisco network had actively gathered/netted in talents from other parts of the USA and good part of the planet earth. On this particular trip, more than ever, I have gained so much information, hope, and optimism for the future of solar industry and technology during Intersolar North America 2015, that I can truly appreciate such netting mechanism radiated from this little area of approximately 46 sq mi. That is why the artist/sculptor Janet Echelman from Tampa, FL , has her sculpture displayed in San Francisco International airport terminal 2 instead of in Tampa, FL.   In the short 3-4 days of Intersolar North America 2015, more than ever before, I can see the future certainty of Solar Tsunami. Coming from a background of mathematics and engineering (civil and mechanical), I’ve gained much of my understanding for the power/energy industry by having an in-house (hubby) technical advisor with electrical engineering background. What seemed to me, intuitively, the natural solution for Energy-Pollution-Economy-Climate Change-International Conflicts during my freshman year in college more than three decades ago, the Solar Energy, will finally be in the main stream!

There will be a series of posts and videos from Intersolar North America 2015 during the remaining of this week and good part of the next week demonstrating how Solar Energy will soon be in the main stream. World wide, we have Germany to be thankful for. USA wide, we have CA and San Francisco to be thankful for.

Now, for a recent press release from Sonnen-Batterie ( winner of Bloomberg 2015 New Energy Pioneers Award and is attending Intersolar North America 2015 at booth #8121.), below:

Sonnenbatterie (Solarbattery) Is Now Offering Its Innovative Products in the United States For the first time in the US, Sonnenbatterie is taking orders for residential and commercial smart energy storage products for distribution through certified channel partners, Sonnenbatterie Centers

Los Angeles, Calif. – July 13, 2015 – Sonnenbatterie, market leader for smart energy storage systems with offices in Los Angeles, California and Bavaria, Germany, today announced that US versions of the residential and commercial products that have earned the reputation of market leader in Europe are now available for ordering and shipment in the US for the first time. Demos of the new products and applications for channel partners will be available at Intersolar North America, Booth #8121.

Today’s news comes on the heels of recent announcements regarding the company’s new research and development facility in Atlanta, GA, and a non-exclusive North American distribution deal with Sungevity.

“I’m very happy to announce that Sonnenbatterie is officially open for business in North America!” said Boris von Bormann, CEO of Sonnenbatterie USA. “Over the last five years, the name Sonnenbatterie has become synonymous throughout Europe with high quality, beautiful design, and easy-to-use home and commercial energy solutions. We’re delighted to invite American consumers to enjoy the Sonnenbatterie experience for themselves.”

Sonnenbatterie products are now available in North America exclusively through channel partners called Sonnenbatterie Centers. Sonnenbatterie Centers are very often local solar installers that enjoy a certain level of geographic exclusivity, given they meet certain volume requirements. Interested parties can seek an application at the company’s booth at Intersolar North America (Booth #8121).

Sonnenbatterie is the German market leader for lithium storage systems with corporate and manufacturing headquarters in Wildpoldsried, Germany, 90 minutes from Munich. The company has sold over 8,000 units of its intelligent energy storage system to homeowners and businesses since entering the market in 2011.

Coupled with a solar energy system, Sonnenbatterie systems can supply residential owners with 100 percent of their energy needs, in addition to providing backup power for the home and taking advantage of different tariff structures for off-peak vs. on-peak use. For commercial customers, Sonnenbatterie helps reduce demand spikes that lead to peak load charges.
