Numerical assessment of optoelectrical properties of ZnSe-CdSe solar cell-based with ZnO antireflection coating layer.

In this work, a numerical assessment of the optoelectrical properties of the ZnO-ZnSe-CdSe heterojunction for a thin and cost-effective solar cell was made by using the PC1D simulation software. The photovoltaic (PV) properties have been optimized by varying thicknesses of the absorber layer of the p-CdSe layer, the window layer of n-ZnSe, and the antireflection coating (ARC) layer of ZnO, a transparent conductive oxide with enhanced light trapping, and wide bandgap engineering. There is a positive conduction band offset (CBO) of ΔEc = 0.
