Scarcity of fossil fuel and global warming issue lead us to investigate renewable and green energy sources. Photovoltaic conversion of sunlight into electricity is the most reliable one to mitigate the huge future energy demand. Cadmium telluride (CdTe) photovoltaic technology is the most suitable one, based on thin film CdTe to absorb and convert sunlight to electricity. We mainly emphasize on effect of variation of different parameters on the efficiency of CdTe thin film solar cell. Result shows that variation of electron/hole mobility gives a slight improvement in efficiency which is not a significant one, though variation of hole mobility gives higher efficiency than variation of electron mobility. Again varying the thickness of Cds layer also gives slight improvement on efficiency of CdTe solar cell. But the rate of change of efficiency is quite low.
