The U.S. National Renewable Energy Laboratory has validated conversion efficiencies of 14.1% for flexible copper-indium-gallium-(di)selenide (CIGS) solar-cell materials produced on Ascent Solar’s 1.5MW commercial pilot line in Littleton, CO. The company’s internal testing shows active-area peak efficiencies for its full-size monolithically integrated CIGS-on-polyimide modules reaching 11.7%, with median efficiencies on the line averaging between 10.5 and 11%-plus, according to president/CEO Farhad Moghadam.
