XsunX reaches 15.1% conversion efficiency with CIGS thin-film solar device
(ADPnews) – Nov 11, 2010 - US-based thin-film solar cell manufacturer XsunX (OTC:XSNX) has further enhanced the conversion efficiency levels of its hybrid copper-indium-gallium-selenide (CIGS) thin-film solar device to 15.1%.
With other market-ready thin-film technologies functioning within the range of 8-11% for solar modules, the company’s CIGSolar technology illustrates conversion efficiency that may soon lead to gains over current technology, XsunX said on Tuesday.
CIGS thin-film researchers have concluded the theoretical limit for CIGS solar technology tops at 29% conversion efficiency, although the highest percentage ever achieved was 20% in a laboratory setting.
"It's important to remember that we are developing our technology on the same size substrates we intend to use in our commercial systems, about the same size as a silicon solar cell, so the efficiency levels we achieve in the laboratory we believe will be transferable to what we can offer the market," said XsunX CEO Tom Djokovich.
The company said that the combination of leveraging existing branded manufacturers to deliver its systems and having branded module assemblers integrate the CIGSolar technology into their products allows it to significantly reduce the need for debt or equity financing necessary to build factories directly.
