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.

Solar Decathlon (1)

Share

Hi, Friends and Readers of Sun Is The Future,

If you are in favor of renewable/CLEAN energy, please sign the petition page showing support for FIT/CLEAN Program at http://sunisthefuture.net/?page_id=1065 Thank you.

Let’s take a break from the political aspect of renewable energy and shift our attention to education and R & D for a moment. The coming series will be presentations of Solar Decathlon. Solar Decathlon of the U.S. Department of Energy is an international competition started/created by Richard King in 2002 (also held in 2005, 2007, 2009)that challenges 20 or so collegiate teams to design, build, and operate the most appealing and effective energy efficient solar-powered house. The winning team would have a design that best blends affordability, consumer appeal, design excellence, and optimal energy production consideration.

The next Solar Decathlon event is scheduled to take place at the National Mall’s West Potomac Park from September 23 to October 2, 2011. It will be open to the public and free of charge, weekdays: 10:00 A.M.-2:00 P.M., weekends: 10:00A.M.-5:30 P.M.

It is intended for public/visitors to tour ultra-efficient houses, to gather ideas to use in their own homes, and learn how to maximize energy efficiency in their own homes.

More information may be found at:  http://www.solardecathlon.gov/

The Solar Decathlon challenges the next generation of innovators and entrepreneurs to become pioneers of clean energy technology and efficient building design,” said Secretary Chu.  “This is a great opportunity for these talented students to showcase cutting edge technologies that will change the way we build homes and save families money.”

The competition is presented by the U.S. Department of Energy and organized by NREL (National Renewable Energy Laboratory).  There is also a Solar Decathlon Europe, established in 2007 between U.S and Spain, and a Solar Decathlon China established between U.S. Department of Energy and China’s National Energy Administration, Peking University, and Applied Material in 2011 and will be held in 2013.

Here at Sun Is The Future, there will be presentations of various designs from different parts of the world.  Be prepared to be awed!
