Investigating the impact of MASnBr3 absorbent layer thickness on FTO/TiO2/MASnBr3/CuI perovskite solar cells characteristics

This work involved designing a solar cell with layers of fluorine-doped tin oxide, titanium dioxide, methylammonium tin bromide, and cuprous iodide. The impact of absorbent layer thicknesses ranging from 0.2 μm to 2.5 μm on developed PSC properties was examined. The thickness of the absorption layer that performs the optimally is discovered to be 0.2 μm. The synthetic solar cell provided an open circuit voltage of 1.07 V, a short circuit current of 34.356 mA/cm2 , an efficiency of 30.68%, and a fill factor of 83.404 at an optimal thickness of 0.2 μm. The findings proved the developed PSC's cost-effectiveness, increased environmental sustainability, and robustness compared to traditional counterparts.
