Abstract: Recently, theoretical studies based on density functional theory have shown that the double perovskite Rb2PtI6 exhibit excellent optoelectronic properties that are relevant for photocatalytic and photovoltaic applications. In this work, novel lead-free halide double perovskite solar cells with the initial architecture FTO/CdS/Rb2PtI6/Spiro-OMeTAD/C are simulated for the first time using SCAPS-1D device modeling. With the optimization of the thicknesses of the FTO, seven-hole transport layers (HTL), Rb2PtI6 absorber and six-electron transport layers (ETL), we have identified four high-performance solar cells with the best efficiency PCE of 20.54%. Among them, the solar cell FTO/SnO2/Rb2PtI6/MoSe2/C is studied under some factors affecting device performance such as, acceptors and defects densities, parasitic series and shunt resistances, working temperature and back contact materials. Our results show that the photovoltaic performance efficiency PCE is boosted to 26%, placing the Rb2PtI6-based solar cell as potential eco-friendly high efficiency solar cell. We hope that our results will be useful for future experimental studies.
