Thin Film Takes Solar Efficiency Crown

German researchers have broken the record for thin-film PV efficiency, achieving 20.8%. This milestone is especially important because it is the first time thin-film has exceeded the efficiency of standard multicrystalline silicon solar, which currently reaches 20.4% for peak performance. One of the reasons silicon-based PV still dominates the market is its greater ability to convert sunlight into electricity. When thin-film PV first became viable, […] Read more


Solar Acronyms 101

“I applied for an ITC rather than a PTC and my neighbor has a PPA, but we both get SRECs that our utility can purchase to fulfill the state’s RPS…” What did you just say? For those who are new to the world of clean energy, the plethora of acronyms that are thrown around when discussing […] Read more


IBM Wants More Solar & Wind in the Smart Grid

Computing giant IBM has developed an advanced power and weather modeling technology that will increase the reliability of renewable energy resources. The IBM solution combines weather prediction and analytics to accurately forecast the availability of wind power and solar energy. This will help utilities integrate more renewable energy into the power grid. The solution, named […] Read more


Will Nanosolar Survive?

Earlier this year Nanosolar went through a round of layoffs. Our sources claimed 75 percent of the staff was let go with 60 days’ pay. Here’s a California WARN notice showing all 170 employees to be lost on April 15. We spoke with two sources close to the company under conditions of anonymity. There are […] Read more


Dow Chemical Gobbles Up NuvoSun

NuvoSun, a thin-film solar firm founded by former MiaSolé CEO Dave Pearce, was just acquired by Dow Chemical. Dow had invested in the firm in early 2010. According to sources close to the deal, NuvoSun is now a wholly owned subsidiary of Dow Chemical. Dow has not yet responded to our inquiries. Presumably, the NuvoSun […] Read more

Empa Scientists Acheive 20.4% Flexible CIGS Efficiency

A record breaking thin film solar cell has been developed by scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology. A team of researchers led by Ayodhya N. Tiwari at the institute’s Laboratory for Thin Film and Photovoltaics have achieved 20.4 percent energy conversion efficiency for their C.I.G.S. solar cells on flexible […] Read more


Peel and Stick Solar

A new ‘transfer’ style application process allows thin, flexible solar panels to be applied to virtually any surface from business cards to roofs to windowpanes. For all their promise, solar cells have frustrated scientists in one crucial regard – most are rigid, reports Stanford University’s Glen Martin. They must be deployed in stiff and often […] Read more


Will Future Cell Phones Save Flexible Solar?

Copper-indium-gallium-diselenide, also known as CIGS solar cells are enabling a new suite of flexible applications from solar roof tiles to consumer electronics such as Apple and Samsung smartphones. CIGS have the competitive advantage that they can be deposited on flexible substrates as opposed to conventional solar panels, which enables a variety of niche products. A […] Read more
