New materials and deposition techniques for highly efficient silicon thin film solar cells

This paper reviews recent efforts to provide the scientific and technological basis for costeffectiveand highly efficient thin film solar modules based on amorphous (a-Si:H) andmicrocrystalline (mc-Si:H) silicon. Textured ZnO:Al films prepared by sputtering and wetchemical etching were applied to design optimised light-trapping schemes. Necessaryprereq..
