Numerical Simulation of an Improved CZTS/WS2 PV Cell by SCAPS 1-D

Abstract

CZTS solar cells are promising among the third-generation solar cell. Because of its earth abundant materials and less toxicity CZTS solar cell can perform a sustainable role as an absorber layer. The optimization of a buffer layer is still a challenge and efficiency are still low than other thin film solar cells. In this study, WS2 buffer layer have been used to simulate the PV cell structure in SCAPS-1D simulation software. No research has been found where CZTS and WS2 is used together. We have achieved a maximum efficiency of η = 18.90 % at 300 K working temperature and other factors i.e., Voc, Jsc and FF are also promising. The highest certified efficiency of CZTS solar cell is nearly 12%. The simulation profile can be a guideline for fabricating the improved PV cell.

Investigating Ag2S quantum dot buffer layer in CZTSSe photovoltaics for enhanced performance

“…To assess the quality of photovoltaic cells, various important parameters such as FF, short circuit current, open circuit voltage, and conversion efficiency (η) need to be determined. These parameters are interconnected and can be calculated using specific equations derived from relevant research papers (Equation [6,7] [43]).…”

“…Silicon (Si) is one of the most commonly utilized absorber materials. However, it has limited processing capacity, high-priced, and has an efficiency of 25.7 ± 0.5% [7]. By utilizing the Cadmium sulfide layer as a buffer, CdS thin film, the effectiveness of second-generation CIGS and CdTe solar cells has increased to 23% and 21%, respectively, at the laboratory scale [8].…”
