英文摘要	In this work, the performance of p-i-n hydrogenated amorphous silicon thin film solar cells by adopting n-type silicon carbide (n-SiCx:H) layer was investigated. By varying CH4/SiH4 gas flow ratio, refractive index and electrical conductivity of n-SiCx:H thin films were changed in the range of 3.4 to 3.8 and 1.48E-5 to 1.24 S/cm, respectively. Compared with solar cells with n-Si:H/Ag configuration, short-circuit current density (J (sc) ) of solar cells with n-SiCx:H/Ag configuration was improved up to 8.4%, which was comparable with that of solar cells with n-Si:H/ZnO/Ag configuration. Improved J (sc) was related with enhanced spectral response at long wavelength of 500-800 nm. It was supposed that the decreased refractive index of n-SiCx:H layer resulted in the increased back reflectance, which contributed to the improved J (sc). Our experiments demonstrated that n-SiCx:H thin films were attractive choice because they functioned both as n-layer and interlayer in back reflector, and their deposition method was compatible with preparation process of solar cells.
