Oct 26 2009 | 11:02am ET

Colorado-based Ascent Solar Technologies says it has achieved 14% cell efficiency for its copper, indium, gallium, selenide (CIGS) thin-film solar cells.

The U.S. Department of Energy’s National Renewal Energy Laboratory (NREL) measured 14.01% cell efficiency for Ascent Solar CIGS material. Ascent announced a peak efficiency of 11.7% for its integrated CIGS modules manufactured at its Fab1 (1.5MW) plant in Littleton, Colorado.

Dr. Farhad Mogahadam, Ascent president and CEO, said in a statement, “This is a significant breakthrough in demonstrating our ability to achieve thin-film CIGS cells with 14% efficiency from regular production machines. Ascent Solar’s ability to manufacturer monolithically integrated modules with efficiency as high as 11.7% in regular production serves as a vital element to our low cost-per-watt manufacturing goal.”
