An organic-inorganic perovskite formamidinium tin iodide (HC(NH2)2SnI3– FASnI3) is used as light absorbing layer in photovoltaics due to its lead-free nature, wider bandgap of 1.41 eV and better temperature stability than CH3NH3SnI3. In the present investigations, SCAPS simulation with comparison to...
