Abstract
In this research article, the performance of the solar cell having the structure (Ag/ZnO:Al/CdS/SnS/p+-SnS/Mo/Glass) is investigated in detail using SCAPS-1D software. This work was carried out to study the performance parameters of SnS based solar cell with an p+-SnS layer as the back surface field (BSF). The efficiency (η) of the solar cell increased to 7.11% with the inclusion of the p+-SnS BSF layer and after all the optimizations of the various parameters were completed. The open circuit voltage (Voc) and the short circuit current (Jsc) of the designed solar cell enhanced up to 359 mV and 27 mA/cm2 after adding p+-SnS BSF layer. The performance of a heterojunction solar cell is reported to be influenced by a number of parameters, including the thickness of the buffer, absorber, and BSF layers, carrier concentration, defect density, and the device's series and shunt resistance. Also depositing a p+-SnS layer is quite simple, economic and the lattice mismatch is less with the SnS layer. All these findings reveal that p+-SnS layer could be a promising BSF layer to enhance the performance of SnS based heterojunction solar cells.
