Abstract
In this study, an innovative solar cell utilizing antimony selenide (Sb2Se3) as a base material and incorporating a dual absorber layer is comprehensively examined using the Solar Cell Capacitance Simulator (SCAPS-1D) tool. The aim is to assess the performance of the solar cell with different absorber layers in combination with Sb2Se3. Results demonstrate that the solar cell employing an organic CH3NH3SnI3 absorber layer alongside Sb2Se3 achieves superior efficiency compared to one with an inorganic CZTS absorber layer. The two absorber layers investigated are the inorganic Copper Zinc Tin Sulfide (CZTS) and the organic methylammonium tin iodide (CH3NH3SnI3 The dual absorber layer configuration proves advantageous by enhancing light absorption. The solar cell architecture comprises ZnO/i-ZnO/Sb2Se3/CZTS or CH3NH3SnI3/NiO layers, resulting in an improved efficiency of up to 36.70%. Throughout the analysis, parameters such as concentration, band gap, thickness, and temperature are systematically adjusted to evaluate the behavior of this unique solar cell structure. The findings from the study indicate a noticeable enhancement in the performance of Sb2Se3 solar cells when employing the bilayer absorber structure comprising Sb2Se3 and CH3NH3SnI3.
