摘要

This article presents a numerical investigation of a heterostructure coper-zinc-tin-sulfide-based solar cell (ZnO/CdS/CZTS) with different hole transport layers (HTL). The main objective of this research is to investigate the series and shunt resistance effect on the performance of the proposed CZTS-based heterojunction solar cell. The proposed cell has been designed considering the ideal and practical condition of series and shunt resistance using SCAPS-1D simulation software. On top of that, different HTL layers like CuO, NiO, and SnS have been inserted between the back contact and CZTS absorber layer to improve the cell’s performance. In an ideal solar cell, the efficiency is increased from 18.32 to 23.91%, 25.68%, and 29.75% and in a practical solar cell, the efficiency is increased from 17.19 to 22.44%, 24.09%, and 27.89% for adding CuO, NiO, SnS HTL layer respectively. These findings reveal that at a specified ratio of series and shunt resistance, there is an optimum value of series and shunt resistance to obtain maximum solar cell efficiency.
