摘要
Methods of forming thin film solar cells with a metallic substrate are described, as well as solar cells and solar cells strings. The front surface of the metallic substrate is polished to form a polished front surface so that the average roughness of the polished front surface is less than 50 nm. The back surface of the metallic substrate is roughened to form a rough back surface so that the average roughness of the conditioned back surface is more than 500 nm. A Group IBIIIAVIA compound absorber layer is formed over the polished front surface.
