Fabrication the Texture Zinc Oxide Thin Films and its Application in Hydrogenated Amorphous Silicon Solar Cell
The pyramid-like textured ZnO film was prepared directly by magnetron sputtering on the self-supporting substrate of ZnO:Al film fabricated by sol-gel. The performance of amorphous silicon solar cell has been studied using the textured ZnO film as a front electrode. It was found that: (1) using the textured ZnO film as an amorphous silicon solar cell front electrode, it can be improved the open voltage, but the fill factor and conversion efficiency was depraved; and (2) inserting a protocrystalline silicon buffer layer between ZnO and p-a-SiC:H, the performance of solar cell was improved obviously. For example, its conversion efficiency increases from 7.3% for the SnO2: FTCO to 7.9% for the ZnO/pc-Si:H TCO.
