Ascent touts 14% efficient flexible CIGS cells

Ascent Solar says it has achieved two new efficiency marks for its CIGS technology on production lines: 14% for the cells themselves, and 11.7% for integrated CIGS modules.

October 22, 2009 – Ascent Solar says it has achieved 14% cell efficiency for its copper-indium-gallium-selenide (CIGS) on flexible plastic substrate using “regular production machines” at its Fab 1, a 1.5MW production plant, a mark verified by the US Department of Energy’s National Renewal Energy Laboratory (NREL). The company also says it has achieved a peak efficiency of 11.7% for its monolithically integrated CIGS modules.

Ascent Solar president/CEO Farhad Mogahadam (an ex-GM/VP of Applied Materials’ thin-film unit, hired this summer) called the 14% mark “a significant breakthrough in demonstrating our ability to achieve thin-film CIGS cell.”
