Abstract
This research includes study the electrical properties using programming simulation SCAPS-1D, depending upon on numerical analysis from simulation of solar cells, where solar cell consisting of Cadmium Telluride (CdTe) used as absorber layer with thickness (0.05-5.0µm) and the window layer CdS:O with thickness (0.025µm) and Buffer Layer (Zn2SnO4) with thickness (0.05µm), (FTO) layer as transparent conductive oxide layer (TCO) with thickness (0.1µm), and added background reflection layer (BSF) which placed between metal back contact layer and the absorption layer in order to increase the amount of Voc and the efficiency of the solar cell because the background reflection layer (BSF) works to reduce recombination in the back contact, and the carriers are strengthened by reversing it towards the main link. With a thickness of (1.0µm), the results obtained were {Voc=0.83V, Jsc=36.90mA/cm2, FF=85.55%, η= 26.33%}. The thickness of the absorption layer has been studied and the effect of temperatures and bandgap energies was studied.
