The a-Si in its hydrogenated (a-si:H) form has low defects, and it is used for solar cell manufacturing. In a-Si, there are about 10 21 per cm 3 defects, while a-Si:H has 10 15 to 10 16 per cm 3 defects . The efficiencies of these thin-film cells are quite low (5–7%) as compared to other solar cell technologies . The initial illumination ...
