Abstract
Sb2Se3 photovoltaic cells have garnered much attention recently because of their inexpensive manufacture and long-term stability. So, different buffer layers were investigated using the SCAPS software to improve the device's output. By comparing J-V characteristics and QE for cells with different ETLs, WS2 was discovered to be the best ETL. The impact of carrier concentrations, the active layer, ETL and HTL thickness, absorber density of defects, and electron affinity were also investigated. It was discovered that WS2 could be a good substitute for conventional ETLs. After optimization, efficiency is 30.03%, FF is 87.13%, JSC is 37.15 mA/cm2, and VOC is 0.928 V. This research provides a new strategy to fabricate high-efficiency and Cd-free Sb2Se3-based photovoltaic cells.
