The Rb 2 PtI 6 ‐based perovskite solar cell (PSC) was studied using SCAPS‐1D simulations, incorporating CdS as the electron transport layer (ETL) and MoO 3 as the hole transport layer (HTL). We systematically evaluated multiple ETL CdS, SnS 2 , SnO 2 , TiO 2 , ZnO, and MZO (Magnesium Zinc Oxide) to determine the optimal choice for device performance. The research concluded that the FTO/CdS/Rb 2 PtI 6 /MoO 3 /Au functions as an efficient ETL (CdS). Furthermore, A comprehensive study of the proposed PSC has been conducted, evaluating its quantum efficiency (EQE), current density–voltage ( J – V ) characteristics, capacitance–voltage ( C – V ) behavior, and carrier generation‐recombination dynamics. The study further explored the performance dependence of the CdS/Rb 2 PtI 6 /MoO 3 device on parameters such as absorber layer thickness, bulk and interface defect densities, operating temperature, and the work function of the back‐contact metal. To enhance efficiency, it has also optimized the interfacial defect densities at the CdS/Rb 2 PtI 6 and Rb 2 PtI 6 /MoO 3 junctions. A solar cell structure FTO/CdS/Rb 2 PtI 6 /MoO 3 /W has been achieved a high‐power conversion efficiency (PCE) of 33.50%, open‐circuit voltage ( V oc ) of 1.137 V, a short‐circuit current density ( J sc ) of 34.57 mA cm −2 , and a fill factor (FF) of 85.26%. This simulated efficiency of 33.50% represents an idealized theoretical upper‐bound, achievable only under optimized defect densities and interface conditions, providing a performance ceiling to guide future experimental efforts in defect passivation and interface engineering. These results demonstrate the strong potential of Rb 2 PtI 6 as a stable, environmentally friendly perovskite absorber and provide guidance for experimental realization through defect passivation and interface optimization.
