Abstract
A systematic step-by-step analysis of the optical characteristics of ZnO/CdS/CuInSe2 solar cells prepared by the selenization technique is reported. The CuInSe2 layer was found to be rough, with a surface feature size of approximately 0.7-1 μm. The final feature size of the cell after ZnO deposition is approximately 0.8 μm. The texturing provided by CuInSe2 and ZnO and the index matching combine effectively to reduce the reflectivity of the ZnO/CdS/CuInSe2 structure to about 5% over the entire spectral range. An estimate of the losses in the window layers and their effect on cell performance is provided
