The SCAPS 1D was employed to improve the device in the Rb 2 SnI 6 -based PSC, which utilized tungsten disulfide (WS 2 ) as the electron transport layer and cadmium telluride (CdTe) as the hole transport layer (HTL). To identify the most suitable electron transport layer (ETL), we initially investigated WS 2 , SnS 2 , PCBM, and C 60 . The ITO/WS 2 / Rb 2 SnI 6 /CdTe/Ni structure proved to be the most effective ETL after extensive investigation, demonstrating a power conversion efficiency (PCE) of 24.95%, a V oc of 1.0896 V, a J sc of 44.6795 mA cm 2 and an FF of 82.71%. Subsequently, we evaluated the impact of the absorber thickness, ETL thickness, and defect density on the device's effectiveness in the Rb 2 SnI 6 , WS 2 , and CdTe layers. We further investigated the effect of adjusting the interfacial defect densities at the CdTe/Rb 2 SnI 6 and Rb 2 SnI 6 /WS 2 interfaces to optimize the device's capabilities further. Additionally, we examined the proposed PSCs' quantum efficiency (QE), current density-voltage (J-V), shunt resistance, series resistance, capacitance-voltage, working temperature, and generation-recombination parameters. The results of these simulations provide valuable information for the excellent scientific fabrication of an inorganic PSC that is based on Rb 2 SnI 6 .
