摘要: The improved performance for hydrogenated microcrystalline silicon-germanium (mu c-Si1-xGex:H, x similar to 0.1) p-i-n single solar cells with hydrogenated microcrystalline silicon (mu c-Si:H) field-enhancement layers (FELs) is demonstrated for the first time. The fill factor (FF) and conversion efficiency (eta) increase by about 19% and 28% when the thickness of the mu c-Si FEL is increased from 0 to 200 nm, it is attributed to the longer hole life-time and enhanced electric field in the mu c-Si0.9Ge0.1:H layer. Therefore, we can successfully manufacture high-performance mu c-SiGe:H solar cells with the thickness of absorbers smaller than 1 mu m by conducting FELs. Moreover, the simulation tool is used to simulate the current-voltage (J-V) curve, thus we can investigate the carrier transport in the absorber of mu c-Si0.9Ge0.1:H solar cells with different EFLs.
