Device Optimization and Defect Analysis of Sr3BiCl3-Based Perovskite Solar Cells by SCAPS-1D

In this study, we conduct a thorough numerical analysis to examine the photovoltaic performance of Sr3BiCl3-based perovskite solar cells (PSCs) using the SCAPS-1D simulator. The study investigates the Ag/FTO/TiO2/Sr3BiCl3/MoO3/Ni device configuration, with the objective of assessing the impact of bulk and interface defect states on total device performance. The simulated device achieves a power conversion efficiency (PCE) of 27.56% when the Sr3BiCl3 absorber layer has a thickness of 1000 nm, a band gap of 1.541 eV, a defect density of 1014 cm-3, and a doping concentration of 1018 cm-3.
