Solar Ovonics makes this claim for their efficiency: . Triple Junction technology provides unprecedented levels of efficiency and stability for amorphous silicon solar cells (stabilised aperture area cell efficiency of 7.0 - 7.5%). Each cell is composed of three semiconductor junctions stacked on top of each other. The bottom cell absorbs the red light, the middle cell the green/yellow light and the top cell absorbs the blue light. This spectrum splitting capability is one of the keys to higher efficiencies and higher energy output, especially at lower irradiation levels and under diffuse light. uni-solar.com uni-solar.com Under diffuse light conditions, where total radiation is lower, their conversion efficiency rises to 9%. This is less electricity produced, but a higher percentage of the total light. .
