In this work, we demonstrate the fabrication of (FAPbI3)1−x(MAPbBr3)x perovskite solar cells (PSCs) with various composition ratios of x, (x = 0, 0.1, 0.125, 0.15) employing spin-coating method. The as-prepared composite perovskite film acts as an active light-harvesting layer, whereas tin oxide SnO2 and Spiro-oMeTAD function as electron and hole transporting layer, respectively. It was found that the addition of MAPbBr3 into FAPbI3 stabilized the perovskite phase, leading to more uniform and dense morphology. Incorporation of MAPbBr3 in perovskite film also results in higher optical absorption and enhanced photovoltaic properties, with PSC device at x = 0.125 recorded the highest power conversion efficiency (PCE). In summary, this study offers insights on how compositional engineering modulates the micrstructural properties and device performance of the perovskite films. |
