Abstract: In this research, we have used the AMPS-1D program to study the enhancement of the Cadmium telluride cell efficiency by studying the relationship between efficiency and some variables, such as the thickness and doping density of the cell layers, type of the back contact metal, and changes in solar radiation and temperature. Simulation results showed that the efficiency increased largely with the increase in the thickness of the absorbent layer CdTe, until the value of (1500 nm), by reducing the thickness of the layer of CdS (n-type), and it does not depend on the thickness of the front contact layer (SnO2). The efficiency depends largely on the doping concentration of the absorbent layer (NA). When the efficiency increases with vaccination rate up to the value 1016 cm-3, then it does not increase significantly, while a higher efficiency is reached when the vaccination of CdS layer is at the value 1017 cm-3. The cell has a high stability at high temperatures with a decreasing rate of 0.08%/°C. The efficiency depends on the type of metal used as a back contact material in the cell under study, and showed that the Aluminum (Al) gives higher efficiency than other metals. As a result installation of Cadmium telluride cell by adoption of the values obtained increases the efficiency of the cell from 13.8% to 19.5%.
