Stion CIGS Solar Modules Reach New Efficiency Level


Stion, a manufacturer of thin-film solar modules, says the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) has verified 14.8% aperture efficiency (13.4% module efficiency) for the fully certified commercial copper indium gallium diselenide (CIGS) modules (65 cm x 165 cm) produced at its Hattiesburg, Miss., factory.

According to the company, this 145 W module has the highest efficiency verified by NREL for a monolithically integrated CIGS module manufactured on a commercial production line, and it exceeds the 140 W module produced by Stion on its San Jose, Calif., pilot line last August.
