Abstract :
Hydrogenated amorphous silicon (a-Si:H)-based solar cells with a double-junction tandem structure have been studied with a view to improving the light-induced degradation in photovoltaic performance. Conversion efficiencies of 11.4% for a 1 cm2 tandem cell. 9.7% (in total area efficiency) for a 30 cm×40 cm tandem submodule, and 8.5% (in total area efficiency) for a 40 cm×120 cm tandem submodule were achieved. The stabilized efficiency of the 11.4% cell after a 1000 h light soaking was 10% under open-circuit conditions
