Abstract

In the present study, the SnS thin films have been grown using the sol gel spin coating technical deposed on a glass substrate. The structural analysis of SnS thin films was examined using X-ray diffraction (DRX). The optical properties of SnS thin films have been investigated using the spectrophotometer UV-V, and we calculated the sum of the optical parameters such as the absorption coefficient, refractive index, the extinction coefficient, the real and imaginary part of the dielectric constant, and the optical conductivity. The electrical resistivity has been calculated using the four-point probe method. The performance of the SnS based proposed solar cells studied from the numerical simulation using SCAPS-1D software. The SnS-thickness, CdS-thickness, and ZnO-thickness are optimized. The SnS-band gap optimization showed that the optimal value is 1.55 eV this is similar to the value found experimentally (∼1.58 eV). The influence of the operating temperature, series and shut resistor, and SnS/CdS charge interface defect on the parameters on the performance solar cells are investigated.
