In this work we present Graphene oxide (GO) material as a potentially important component of CdTe-based solar cells, due to its outstanding optical and electrical properties. This paper investigates the electrical characteristics and photovoltaic performance parameters of GO/CdTe solar cell using the SCAPS-1D software. It is essential to comprehend how solar cell properties such as temperature, thickness, doping concentration, and operational resistors, R-s and R-sh, impact photovoltaic device performance. According to the simulation results, the current J changes exponentially as a function of the applied voltage. In addition, the GO/CdTe solar cell reach its highest power conversion efficiency of eta = 10.36%, at these parameters: open circuit voltage V-oc = 0.4704 V, short circuit current density J(sc) = 28.054908 mA/cm(2) and fill factor FF = 78.5%. These parameters were improved by characteristics optimization of GO/CdTe solar cell. The optimized solar cell shows an efficiency of eta = 13.95% for d(CdTe) = 3 mu mandT = 300k. Hence the results obtained from this simulation work open the path for high-efficiency solar cells and are extremely promising for future technological applications.
