Abstract:
In this paper, we present a simulation of a CIGS solar cell with a ZnS buffer layer, performed using the Sil vaco-Atlas simulator. However, we obtained an efficiency of 24.13%,short-circuitcurrent of 37.81 mA/cm2, an open circuit voltage of 740 mV, and a fill factor of 78.78% at was around 1.41 eV, corresponding to an x ratio of 0.5 for the CIGS solar cell using a ZnS buffer layer. We optimized the performance of the ZnS/CIGS solar cell with the improved effects of layer parameters such as thickness and acceptor densities ZnS buffer layers.
