Numerical Simulation of the Performance of Sb2Se3 Solar Cell via Optimizing the Optoelectronic Properties based on SCAPS-1D.

Abstract

The study analyzed the potential of using antimony selenide (Sb2Se3) as a material for solar cells by conducting simulations using the Solar Cell Capacitance Simulator (SCAPS) program. The non-toxic and accessible nature of Sb2Se3, coupled with its potential for high efficiency and low cost, makes it an exciting material for the future of solar cell technology. The analysis focused on various factors, including the thickness of the Sb2Se3 layer, its defect density, band gap, energy level, and carrier concentration, and their influence on the performance of the solar cells. The simulation results indicated that an optimal performance of the devices could be achieved with specific values for the Sb2Se3 layer: an 800nm thickness for the absorber, a defect density less than 1015 cm−3, a band gap of 1.2 eV, an energy level of 0.1 eV (above the valence band), and a carrier concentration of 1014 cm−3. By optimizing these parameters, a maximum efficiency of 30% was attained. Overall, the study's findings offer valuable insights and directions for designing and engineering solar cells using Sb2Se3 as a material.
