摘要：
Cs2AgBiBr6 is a lead-free double halide perovskite, which has attracted attention as a potential replacement to toxic and unstable organic-inorganic perovskites due to its high structural stability, non-toxicity, and unique photoelectric properties. This work presents a Numerical analysis of a lead-free Cs2AgBiBr6-based perovskite solar via SCAPS software. The effect of several input parameters has been analyzed; after selecting the best Holes Transport Layer (HTL) and the best Electrons Transport Layer (ETL), we have optimized their thicknesses as well as their doping densities, we have also analyzed the impact of: the absorber thickness, its defect density (Nt), defect density at ETL/Cs2AgBiBr6 and Cs2AgBiBr6/HTL interfaces, ETL electron affinity, and front/back contact work function on device performance. Finally we obtained a solar device based on Cs2AgBiBr6with a fully inorganic structure. The results show that Cs2AgBiBr6 can play an important role as an absorbing perovskite in the development of solar cell technology.
