Colorado, United States [RenewableEnergyWorld.com] Ascent Solar Technologies, Inc. has achieved its initial target module efficiency goal of 10.0% for its flexible Copper, Indium, Gallium, Selenide (CIGS) monolithically integrated modules. The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) has independently verified that the modules measured as high as 10.4% in conversion efficiency.
The modules tested at NREL were standard 429-cm² modules produced by the company’s 1.5-megawatt (MW) production line that was put into commercial production in the first quarter of 2009.
“Ascent’s high-volume 30-MW commercial plant is scheduled to commence initial production at the beginning of 2010. Module efficiency of 10.0% is a vital element for our low-cost-per-watt manufacturing goal in high volume and will establish Ascent Solar as a leader in the production of lightweight flexible photovoltaics used for portable power and building integrated photovoltaic (BIPV) products,” said Dr. Prem Nath, senior vice president of Production Operations for Ascent Solar.
