Numerical StudiesOn Cs2AgBiCl6 Based All-Inorganic Perovskite Solar Cell Using SCAPS 1D
摘要
Double perovskites, which are lead-free, are potential replacements for lead based perovskites in solar cells, due to their promising features of non-toxicity and substantial stability. Perovskite solar cell (PSC) with a novel double perovskite Cs2AgBiCl6, is designed using SCAPS—1D. The impact of parameters such as charge transport materials, thickness of various layers, valence band offset (VBO), conduction band offset (CBO), absorber & interface defect density on the performance of the PSC are analyzed. The optimized device is ITO/SnO2/Cs2AgBiCl6/Cu2O/Au which exhibits an impressive 19.18% efficiency at ambient temperature. The proposed all- inorganic Cs2AgBiCl6 based PSC could contribute to the development of sustainable, environmentally friendly & highly efficient solar cells in the near future.
