Abstract

wave length range for hydrogenated nanocrystalline silicon (nc-Si:H) thin-film solar cells. The absorption is theoretically found for 1-mu m nc-Si:H cells, and is further enhanced for off-normal incidence. Predicted currents exceed 31 mA/cm(2). Nc-Si:H solar cells with the same device architecture were conformally grown on periodic substrates and compared with randomly textured substrates. The periodic back reflector solar cells with nanopillars demonstrated higher quantum efficiency and photocurrents that were 1 mA/cm(2) higher than those for the randomly textured back reflectors.
