Abstract

Researchers are doing intense research in tin sulfide (SnS)-based solar cells because of their outstanding semiconducting features. In this work, the solar cell capacitance simulator (SCAPS-1D) has been used to do the simulation study of thin films solar cells using SnS absorber layer with different buffer layers (ZnO, ZnSe, CdZnS, TiO₂) in comparison to the toxic CdS buffer layer. Photovoltaic parameters (open circuit voltage, fill factor, short-circuit current density and efficiency) is evaluated as a function of absorber layer thickness, different buffer layer and buffer layer thickness. Device stability at different operating temperature is also evaluated. The simulation results reveal the fabrication of high efficiency SnS based solar cells.
