“…The constant low-field mobilities (µ n and µ p ) are used for each layer as a default model that is independent of doping concentration, carrier densities, and electric field and accounts for lattice scattering due to temperature [65]. Shockley-Read-Hall (SRH) and the Auger (AUGER) recombination models were considered for the ETL layers which are needed to consider the effects of defects (or traps) that cause states in the bandgap as well as third-order recombination process [73,74]. For active material, optical (OPTR) and SRH recombination models were chosen to take into account the effects of the band-band recombination process and trap [73,74].…”

The development of environmentally friendly and highly efficient inverted perovskite solar cells (PSCs) poses a formidable challenge. The potential toxicity of absorbers and the pressing need to effectively passivate interlayers in hybrid organic-inorganic photovoltaics (PV) present major obstacles. To surmount these formidable challenges, we resorted to the SCAPS-1D and SILVACO ATLAS-2D device simulators to leverage theoretical design strategies that engender hysteresis-reduced, efficient, and stable PSCs that are grounded in composition and interface engineering. Further, we carried out optoelectronic characterization measurements to glean a better understanding of the physical mechanisms that govern the operation of the device. The device utilizes mixed-cation perovskites FAMASnI3 as the absorber layer and employs zinc oxide (ZnO) and phenyl-C61-butyric acid methyl ester (PC61BM) as a double electron transport layer (HTL). A double-hole transport layer (ETL) consists of nickel oxide (NiO) and copper iodide (CuI), ensuring a trap-free junction for hole collection and good contact. This inverted PSC structure, combined with the mentioned layers, achieved high power conversion efficiencies (PCEs) of 24.27% and 23.50% in 1D and 2D simulations, respectively. This study effectively illustrates that composition and interface engineering enable eco-friendly perovskite solar cells, leading to improved performance and advancing clean energy.
