Printable mesoscopic perovskite solar cells (p-MPSCs) provide an opportunity for low-cost manufacturing of photovoltaics. However, the performance p-MPSCs is severely compromised by iodine defects. This study presents a strategy incorporating polyaniline (PANI) to achieve both recycling and defect passivation significantly improve p-MPSCs. PANI captures immobilizes ions, establishing stable system that effectively suppresses loss. Additionally, Lewis base properties enable it passivate defects within suppress nonradiative recombination. With synergistic effects, increases power conversion efficiency champion device from 18.28% 20.24%. offers potential solution enhancing with promising implications practical applications.
