Investigation of Different Materials as Buffer Layer in CZTS Solar Cells Using SCAPS

Abstract—Cadmium sulfide (CdS) is widely used as buffer layer of Cu2ZnSnS4 (CZTS)-based thin film solar cell. Due to its toxicity, its alternatives are being explored. In this work, with an attempt to find an alternative to Cadmium sulfide, electrical performances of solar cell with different buffer layers were simulated and recorded. Simulation was carried out with Solar Cell Capacitance Simulator (SCAPS). As buffer layer, other than Cds; Zn(O,S), ZnS, ZnSe, InS and MoS2 were separately used. Zinc compounds are cheap, eco-friendly and they have relatively higher band gap, making them suitable candidate for replacing CdS. Zn(O,S) and ZnS yielded good results with conversion efficiency of 10.28% and 9.82% respectively. This result is favorable for cost-effective fabrication of highly efficient thin film solar cell.

Index Terms—Buffer layer, CdS, CZTS, InS, MoS2, SCAPS, Zn(O,S), ZnSe, ZnS.
