Abstract
The effects of Cu on the properties of CdTe/CdS photovoltaic cells at the device junctions were discussed. The optical bandgap of CdS films was 2.31 eV having thermal diffusion of 50 Å. The modeled quantum efficiency (QE) curves for CdTe lead to a reduction and shifting of the QE response near 500 nm, as the bandgap of the CdA was shifted to lower energy. The Cu films showed that increasing the amount of Cu in the CdS produces a systematic change in the J-V parameters.
