This paper explores the development and simulation of cadmium-free solar cells based on Antimony tri-selenium (Sb2Se3) absorber materials, with the integration of zinc sulfide (ZnS) buffer layers. The aim is to replace cadmium-based materials with environmentally friendly alternatives while maintaining or improving the efficiency of thin-film solar cells. We utilize the SCAPS-1D (Solar Cell Capacitance Simulator) software to model and simulate the electrical and optical characteristics of the proposed solar cell structure. This work used SCAPS-1D software to construct and quantitatively analyze solar cells made of high-efficiency Antimony tri-selenium (Sb2Se3) and Zinc sulfide (ZnS). This study examines how the thickness of the absorber surface and the buffering layer affects the efficiency of solar cells. Cadmium has been avoided because of its significant toxicity to the environment, for making solar cells which is suitable and efficient. Various photovoltaic parameters have been determined using ZnS as a buffer layer. By varying the depth of the absorber layer from 0.6μm to 0.5μm and the thickness of the buffer layer from 0.06 μm to 0.2 μm author tried to investigate the properties of solar cell.

Keywords : SCAPS-1D, Sb2Se3 Solar Cell, ZnS, Absorber Layer, Buffer Layer.
