Single-crystal perovskite with no grain boundaries improves the performance of perovskite solar cell compared with its polycrystalline counterpart. Owing to its stability and excellent defect physics, it has enormous potential in the field of photovoltaics. In this article, a comprehensive numerical evaluation of single-crystal CH₃NH₃PbI₃ solar cell model with an unprecedented n-i-p-type architecture reduced graphene oxide/AgNW-115/Cytop composite (rGO/AgNW-115/Cytop)/TiO₂/CH₃NH₃PbI₃/Spiro-OMeTAD/Au has been presented. Various factors affecting the solar cell’s performance have been rigorously investigated; more specifically, the effect of defect density and thickness of the absorber layer. The impact of the interface layer defect density on the performance of solar cell has also been studied. Finally, the diode parameters of the optimized device were thoroughly investigated to analyze the performance of cell module. By optimized parameters, we obtained power conversion efficiency (PCE) of 22.12% with open-circuit voltage ( ${V}_{oc}$ ) as 1.13 V, short-circuit current density ( ${J}_{sc}$ ) as 22.96 mA/cm², and fill factor (FF) of 85.12% which is considerably better than the best reported values available in the literature.
