dc.description.abstractGrain boundaries and surface defect states in perovskite films damage the charge transport mechanism by acting as nonradiative recombination centers, thus resulting in poor device performance and unsatisfactory long-term stability. For this aim, we added 3,4-dihydroxyphenethylamine hydrochloride (3,4-DpACl) as an effective additive to chlorobenzene antisolvent and used it during perovskite fabrication. The characterization results infer that the 3,4-DpACl material not only assists in forming a smoother perovskite film along with the reduction of residual lead iodide but also brings a passivation effect from the possible chemical interaction between the C═O of 3,4-DpACI molecules and uncoordinated Pb2+ ions of the perovskite material. In addition, employing the 3,4-DpACl tailors the energy levels of the perovskite layer and reduces mismatch energy between the valence band of the perovskite layer and hole transport layer (HTL). Overall, the 3,4-DpACl-contained antisolvent records a champion efficiency of 21.17% for optimized perovskite solar cells (PSCs). The optimized triple-cation PSCs show a higher stability against humidity and irradiance. They maintain 83% of their original power conversion efficiency (PCE) after 1600 h of exposure to ambient air with a humidity level of 35-40%. Furthermore, after 1056 h of irradiance with simulated sunlight in an ambient air environment, they retain 81.6% of their initial PCE.en_US
