Abstract: For commercial purposes in the solar cell field which toxicity and stability of lead-based perovskite solar cells (PSC) are important challenges, the presence of lead-free alternatives like Cs 2 TiBr 6 , Cs 2 AgBiBr 6 and Cs 2 PtI 6 double perovskites seems important. The aim of this study is to numerical evaluation of three double perovskite layers as potential photovoltaic (PV) materials in solar cells with fluorine-doped tin oxide (FTO)/TiO 2 /perovskite/Cu 2 O/Au structures by using SCAPS-1D software. Different composite layers were optimized and analyzed to enable enhanced performance. Numerical results showed maximum power-conversion efficiency of 18.86%, 18.54%, and 26.50% for the suggested PSCs with Cs 2 TiBr 6 , Cs 2 AgBiBr 6, and Cs 2 PtI 6 absorbers. The achieved outcomes confirmed that Cs 2 PtI 6 can contribute significantly to the development of highly efficient lead-free double-perovskite solar cell technology.
