微晶硅锗太阳电池本征层纵向结构的优化
Optimization of the longitudinal structure of intrinsic layer in microcrystalline silicon germanium solar cell∗
摘要
Abstract
Using radio-frequency plasma enhanced chemical vapor deposition, based on the influences of discharge power on structural and photoelectric properties of µc-SiGe:H thin films, RF power profiling technique is developed during the deposition of µc-SiGe:H intrinsic layer. The optimized µc-SiGe:H intrinsic layer not only maintains homogeneity of the crystalline volume fraction along the depth profile, but also forms a band gap profiling configuration from wide to narrow in the direction of growth. By this method, the fill factor and the short-circuit current density of µc-SiGe:H solar cell are significantly improved, and an efficiency of 9.54%for the a-Si:H/µc-SiGe:H tandem solar cell is achieved.关键词
