Abstract

MAPbBr₃ films were deposited on FTO-glass substrates by the spin coating technique. These films were irradiated by Cu ions with a flounce rate of 2×10¹⁴ ions/cm², 4×10¹⁴ ions/cm², and 6×10¹⁴ ions/cm² respectively. MAPbBr₃ films exhibited a crystalline nature and a cubic structure, as verified by XRD. The MAPbBr₃ film irradiated by 4×10¹⁴ ions/cm² Cu ions has a large grain size (33 nm) and a small E_g (2.11 eV). As a result, the trap-state densities within the perovskite bulk were suppressed at interfaces as well as in the bulk material for smooth and improved carrier transportation. The calculated valence and conduction band edges of MAPbBr₃ are ‘-5.60’ and ‘-3.2’, respectively. The film exposed to Cu ions has the CB edge pushed towards the lower value, making it a preferable solar cell material. The non-irradiated and irradiated films by Cu ions have higher carrier life times of 63 ns and 74 ns, respectively. The cell fabricated with ions/cm² Cu ions-MAPbBr₃ film displayed a champion device with FF (0.84), J_sc (9.34 mA-cm⁻²), V_oc (1.098), and PCE (8.59%).
