| Abstract: | The commercialization of high-performance hybrid metal halide perovskite solar cells faces a significant obstacle in the form of long-term instability, specifically caused by weak interfaces between the perovskite/charge transfer layers and defects at the surface and grain boundaries. Passivating the surface is an effective strategy to improve perovskite solar cells’ long-term performance by reducing defects through strong interaction with lead or halide ions. The presence of phosphonium iodide in methyl triphenyl phosphonium iodide (MTPPI) allows it to interact with unconsolidated Pb2+, leading to a reduction in surface defects in the perovskite. Here, the MTPPI was introduced as a hydrophobic material to improve the performance and stability of the perovskite device through the post-annealing passivation method. Compared to pristine MAPbI3, the 0.6 mg MTPPI-passivated films had superior crystal orientation, light-harvesting capacity, smooth and pinhole-free surface. In comparison to other devices, it was discovered that the optimal concentration of 0.6 mg MTPPI-passivated device showed a better power conversion efficiency of 10.2%, Voc of 0.941 V, Jsc of 23.58 mA/cm2, and FF of 45.8%. Furthermore, this champion device outperforms the pristine MAPbI3 in terms of stability in ambient air conditions, maintaining approximately 82% efficiency for 500 h without any encapsulation.
