A Role of Back Contact and Temperature on the Parameters of CdTe Solar Cell

The present work covers the solar cell simulation of cadmium telluride (CdTe) by means of the SCAPS-1D simulation software. The impact of back contact type and operation temperature on operation parameters of solar cell was studied. For the present study, three different types of metals with different work functions have been used in simulation, i.e. silver (Ag), gold (Au) and platinum (Pt). The range of working temperature was 300-400 K. Simulation results confirmed that the back contact type and work functions and temperature strongly influence the parameters of solar cells, especially the PCE, wherein it has been found that the Pt gave a conversion efficiency of 5.7% and Au gave 2.01% efficiency and Ag with 0.04% and best temperature to work is 350 K. The influence of inserting cadmium sulphide (CdS) buffer coat had been studied, and the presence of CdS enhanced the solar cell work.aq
