Theoretical and Experimental Study of Methyl Ammonium Antimony Iodide-Based Lead-Free Perovskite Solar Cells

Methyl ammonium antimony iodide (MA3Sb2I9) perovskite-like materials have gained enormous attention from the scientific community because of their excellent aerobic stability, good optical properties, and less-toxic nature. Herein, we report on the simulation of FTO/TiO2/MA3Sb2I9/spiro-OMeTAD via solar cell capacitance (SCAPS) software. The thickness of the absorber layer, hole-transport layer, or electron-transport layer may significantly impact the photovoltaic performance of the perovskite solar cells (PSCs). In this connection, the thickness of the absorber layer, hole-transport layer, or electron-transport layer was varied during the simulation process and the optimized PSCs demonstrated a good efficiency of 14.90% including an excellent open circuit voltage (Voc) of 1.41 V. Furthermore, we also fabricated MA3Sb2I9-based PSCs and their photovoltaic performance was evaluated. The fabricated PSCs showed a reasonably good efficiency of 1.27% and Voc of 0.51 V.
