Abstract:
A method to produce thin film solar cells in superstrate or substrate configuration is an efficient way to minimize the loss due to absorption in CdS layer and to eliminate the CdCl2 activation treatment step. This is achieved by applying a sacrificial metal-halide layer between the CdS-layer and the CdTe-layer of the solar cells.
