摘要

In this paper, we observe a comprehensive simulation approach for organic/inorganic perovskite-based photovoltaic solar cell under the preconditioned illumination of AM1.5 for distinct device structures. The predominant objective of this work is to obtain the optimized thickness parameters for achieving the best possible efficiency for MASnI(3) based PSC device structures. The present simulation accomplishes considering TiO2 as an electron transport layer (ETL) and Spiro-OMeTAD as a hole transport layer (HTL); inserting the lead-free PVK of MASnI(3) having a precise bandgap of 1.3 eV, under doping concentration of 3.25 x 10(25) m(3) respectively. Therefore, the extensive investigation of the simulated device structures confirms the optimized thickness of the ETL, MASnI3, and HTL respectively as 1 nm, 500 nm, and 10 nm for both the device structures. The optimization of layer thickness under suitable defect density condition yields a much-improved power conversion efficiency (PCE) approaching 22% owing to enhanced J(sc) than the earlier reported value by Noel et al. [20] for the PSC devices.
