Abstract

Antimony selenide (Sb₂Se₃) has remarkable optoelectronic capabilities that make it a promising option for the next generation solar cells. In this work, a solar cell with the structure Al/FTO/CdS/Sb₂Se₃/Mo is modeled and numerically analyzed using SCAPS-1D program. Furthermore, a Al/FTO/CdS/Sb₂Se₃/Sb₂S₃/Mo solar cell structure that uses Sb₂S₃ as the back surface field (BSF) layer is proposed. A comprehensive examination of photovoltaic characteristics for the solar cells was carried out. The optimization process involved adjusting the operating temperature, series and shunt resistance, doping concentration, bulk defect density, back contact metal work function, and thickness of the absorber layer. The optimized Sb₂Se₃-based solar cell with Sb₂S₃ material showed a conversion efficiency of 28.91%, suggesting that Sb₂Se₃-based solar cells have a great deal of potential for further development.
