Theoretical Analysis and Development of Multilayered Ecofriendly Sb₂S₃‐Based Solar Cell Using SCAPS‐1D Framework

Abstract

In this work, we examined the FTO/TiO2/Sb2S3/Au solar cell characteristics via SCAPS‐1D modeling. The research begins with device modeling of the Sb2S3 conventional solar cell based on experimental data, which results in excellent agreement with the conversion efficiency (PCE) recorded in the literature of ∽4.72%. The influence of several factors on the characteristics of conventional solar cells is then investigated, including Sb2S3 thickness, carrier concentration, bulk and interface defects, and buffer layer type (TiO2, WS2, and CdS). An optimal efficiency of 9.97%, Voc of 0.96 V, Jsc of 19.69% FF of 52.26% was found for the FTO/WS2/Sb2S3/Au optimized solar cell. Finally, we investigated the influence of NiO as the back‐surface field (BSF) and parasitic resistance (Rs and Rsh) on the performance of Sb2S3 solar cells. The innovative solar cell design (FTO/WS2/Sb2S3/NiO/Au) with NiO thickness of 20 nm, Rs < 2 Ω.cm‐2 and Rsh > 700 Ω.cm‐2 yielded a high efficiency of more than 14.38%, FF > 68.93%, Voc > 1 V, and Jsc > 20.67 mA/cm2. These qualities allow for the large‐scale manufacture of a solar cell by including it in a manufacturing workflow.This article is protected by copyright. All rights reserved.
