Colorado, United States [RenewableEnergyWorld.com] Ascent Solar Technologies Inc., a developer of flexible thin-film solar photovoltaic modules, announced that it has achieved greater than 9.5% efficiency 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 9.64% in conversion efficiency. The modules tested at NREL were produced on Ascent’s 1.5-megawatt (MW) pilot production line.
“This is significant. Many doubted that a thin-film CIGS solar cell-on-plastic technology could be possible. Ascent Solar not only achieved this, but they now have confirmed efficiencies at NREL on fully integrated, monolithic prototype modules near 10%. This appears to be a substantial leap toward realizing high-performance, inexpensive thin-film solar photovoltaics,” said Lawrence Kazmerksi, executive director at NREL.
