Abstract

The highly efficient CIGS thin-film solar cell is numerically investigated in this paper using solar simulator software wxAMPS (Analysis of Microelectronic and Photonic Structures). WxAMPS is a customized simulation software package mainly used for photovoltaic cells, which supports quick data input and enhanced visualization with its improved user interface. Copper–indium–gallium–diselenide Cu(In, Ga)Se2 (CIGS) is a semiconductor material with chalcopyrite crystal structure that has high conversion efficiency and structural stability. CIGS model- ZnO: Al/ZnO/CdS/CIGS/Mo/substrate is mainly experimental research that considers the physical characteristics, dimensions, and thicknesses of the different layers. The bilayer window and absorber layer with different thicknesses are the critical factors that influence solar cell performance. The bilayer window concept can assist in reducing the loss at the window layer. In this paper, through the numerical simulation, the highest conversion efficiency was achieved, 18.7%, with an optimum bandgap of 1.12 eV with 3000 nm thickness of the absorber layer under AM 1.5G.
