Perovskite Solar Cell Technology of Oxford PV, The Potential Game-Changer

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

At InterSolar North America 2014 in San Francisco, CA, I came across a potentially game-changing technology that holds much promise for low cost solar power in the future.  This technology, 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). The perovskite thin-film solar cells can be directly printed/sprayed onto glass to produce a semi-transparent colored coating. Below is an interview with the Chief Technology Officer, Dr. Christopher Case, of Oxford PV:


The apparent enthusiasm of Dr. Case is seen in his discussion of the perovskite cell technology. One can understand the source of Dr. Case’s enthusiasm. According to Dr. Case, “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.” This perovskite solar cell technology is optimized to drive a paradigm shift in the aesthetics, performance, and cost of BIPV (Building Integrated Photovoltaic) systems, potentially bringing low cost electricity to the solar market much sooner than predicted. It is no wonder the highly respected international journal, Nature, has named Dr. Henry Snaith of University of Oxford as one of the ten people who have made the most difference in science during 2013 in recognition of his work on this next generation solar power technology. Let’s also take a look at the comparison between Convetional PV vs. Oxford PV, below (provided by www.oxfordpv.com):

 

Conventional PV                                                                         Oxford PV_________________

Opaque                                                                                      Range of transparency options

Blue or Black                                                                              Palette of colors and tints

Contains scarce elements and rare earths                                  Sustainable, abundant, organic ingredients

Complex, high temperature and high vacuum manufacturing    Simple screen printing manufacturing processes

High capital cost of manufacturing                                            Low capital cost of manufacturing

Heavy panels physically attached to building                          Aesthetically attractive glazing panels integrated into the building envelope

__________________________________________________________________________________

Without using the titanium dioxide as a semiconductor, this technology results in higher levels of efficiency, much lower processing temperature, and improved cell stability. 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.

Oxford PV has a strong supporting team (such as Kevin ArthurDr. David Fyfe, Paul Vickery, etc.) With its promising future, we, the solar enthusiasts and investors alike, should keep our eyes on Oxford PV in the coming years.

Ideal Power’s 2-Port & 3-Port Hybrid Converters at InterSolar North America 2014

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links and note magenta)

I’d like to share with you an interview at InterSolar North America 2014, in Moscone Center of San Francisco, CA on July 9, 2014. The future of the multi-billion dollar solar industry depends much on the progress in combining PV with energy storage. In this post, Sun Is The Future will present to you Ideal Power’s AWARD winning 30KW Hybrid PV Storage Converter (which is becoming the de facto industry standard to enable PV+storage integration). Ideal Power received its award on June 4th during a ceremony at InterSolar Europe in Munich, Germany, the world’s largest exhibition for the solar industry. Ideal Power’s technology stood out due to its ability to combine PV and battery systems with an efficiency level of up to 97%. It also provides modular flexibility for different applications, particularly in off-grid systems. Due to the dramatic improvement in size, weight, cost, and efficiency over conventional converters, the Hybrid Converter integrates multiple power sources (i.e. PV+storage+grid) to lower the cost of delivering grid resiliency during blackouts such as Superstorm Sandy. I can’t wait to get my hands on the 3-port Hybrid Inverter/Converter (125 lbs) that will enable us to be better prepared for future natural disasters without the dependence on the grid. Currently the 2-port converter system (100 lbs) is used for demand reduction in grid-tied system (currently used in Walgreen of  Southern CA) whereas the 3-port converter will be in one box and creates its own microgrid during power outage.

Below, is an interview with John Merritt, Director of Applications Engineering, of Ideal Power, at InterSolar North America 2014:


Ideal Power’s hybrid converter is the first 3-port product to leverage the Company’s Power Packet Switching Architecture™ (PPSA), which allows it to combine PV inverter capabilities on one DC port, bi-directional battery converter capabilities on the second DC port, and provide an AC port supporting both grid-tied and off-grid applications. It can accomplish these functions with only a modest increase in product size and weight over its established 2-port battery converter and PV inverter products and with no loss of system efficiency. Conventional technology solutions to hybrid power conversion systems combining PV and storage require multiple power conversion steps, thereby reducing efficiency, and multiple power converter units, increasing size, weight and cost. (Ideal Power press release)

CITEL TO EXHIBIT 2016-READY SPD’S AT INTERSOLAR NORTH AMERICA 2014

Share

Dear Friends, Visitors/Viewers/Readers,

(Please click on red links below and note magenta)

Below is the press release from one of the presenters at InterSolar North America in San Francisco, CA in July 8-10, 2014.

CITEL TO EXHIBIT 2016-READY SPD’S AT INTERSOLAR NORTH AMERICA 2014

Miramar, FL – May, 2014 – CITEL, the leader in photovoltaic surge protective devices, is excited to announce that their 2016-ready SPD’s will be featured at Intersolar North America this July. “We are excited to show the solar community our surge protective devices at Intersolar 2014.” said Patrick Coyle, VP of CITEL, “Our SPD’s have been specifically engineered to meet the protection needs of PV systems and ready for the UL updates in 2016.” CITEL continues to lead the way in the solar industry by developing innovative surge protection solutions specifically for photovoltaic applications now reaching up to 1500 vdc.

By their remote nature, Photovoltaic (PV) systems are highly exposed and vulnerable to lightning induced power surges. A PV system that is not equipped with surge protection can be severely damaged or even destroyed in the case of an over voltage such as one that would be caused by a lightning strike. Not only are the panels themselves targets for lightning, so are inverters, combiner boxes, feeder lines, structural supports, and even data lines throughout the system. The risk is so high that international standards have been written specifying the type and locations of SPD’s in a PV installation. A full surge risk assessment is an important step when installing a PV system, in order to identify any safety requirements.

Surge protective devices are essential in order to achieve the ROI that fully operating PV systems are designed to provide. SPD’s provide reassurance that the system will be protected in the lightning-prone environment in which it is placed, thus protecting the investment and avoiding costly downtime, repairs, and replacements. It is essential that anybody considering a PV installation also incorporates the protection of an SPD.

Some of CITEL’s surge protective devices that will be displayed at Intersolar North America are:
 DS60VGPV – UL Type 1 CA DC SPD’s
 DS50VGPV – UL Type 1 CA DC SPD’s
 DS50PVS – UL Type 1 CA DC SPD’s
 DS2x0S-xxDC – Type 2 DC or AC SPD’s
The DS60 and DS50 family of SPD’s are also 2016-ready. By 2016, all UL1449 3rd Edition SPD’s will be required to test and publish a short circuit current rating (SCCR) and pass the intermediate current tests in order to comply with more stringent SPD component assembly standard. The DS60 and DS50 products also have the option to feature CITEL’s patented VG Technology. VG Technology provides the key benefits of increased life expectancy, elimination of leakage current, elimination of working current, and will meet the most stringent UL standards with no conditions of acceptability.
CITEL is proud to have the opportunity to exhibit at Intersolar North America 2014 and to share about the necessity of surge protection in photovoltaic systems as well as the upcoming changes to UL.
