Wide scale production and commercial uses of PSCs are restricted by the toxicity problems associated with the lead
metal, despite the substantial benefits and power conversion efficiency that PSCs have attained over the years. Thus leadfree
metal halide perovskites are the focus of modern study. Here the solid-solution perovskite (CsSn0.5Ge0.5I3), an allinorganic
material devoid of lead as the light absorber layer for obtaining high efficiency PSCs is thoroughly investigated.
The major objective of present work is to analyze superior combination of ETL and HTL for CsSn0.5Ge0.5I3 for getting
affordable, high-efficiency and nontoxic CsSn0.5Ge0.5I3 PSCs. In this work, initially with the use of a one-dimensional solar
cell capacitance simulator (SCAPS-1D) thirty-five, CsSn0.5Ge0.5I3 based PSCs were examined which are formed by the
combination of seven HTLs and five suitable ETLs including ZnO, TiO2, WS2, PCBM and C60. Simulation results showed
that among 35 different configurations the device architecture consisting of ITO/WS2/CsSn0.5Ge0.5I3/PEDOT: PSS/Au had a
higher photo conversion efficiency and stability. This configuration provided PCE of 23.47%. For the different possible
configurations, the impact of varying the absorber, ETL and HTL width on solar cell parameters was carefully examined.
Additionally, the comparison of simulation result obtained by SCAPS-1D software is validated by another simulation
software wxAMPS. Further, the effect of series resistance, temperature and shunt resistance has been studied
comprehensively for the 5 superior configurations out of the 35 combinations taken.
