Abstract :
Progress in polycrystalline thin films facilitated by the US Department of Energy/National Renewable Energy Laboratory (DOE/NREL) program has included: accelerated growth of the US industrial infrastructure supporting CuInSe2 (CIS), CdTe, and Si-film; achievement of a record thin-film CIS power module (4 ft2) aperture area efficiency of 9.7%, verified by NREL; improved aperture area efficiency of 8.1%, verified by NREL for a thin-film CdTe module of area near 1 ft2; progress in improved CIS/Mo adhesion; a breakthrough total area thin-film CdTe solar cell efficiency of 13.4% verified by NREL; and continued success of multilayer outdoor stability tests of prototype CIS and CdTe modules. These and other technical results are summarized
