Bifunctional Molecular Bridge with Tunable Dielectric Constant for Air‐Processed Perovskite Solar Cells
/perovskite layers and a higher dielectric constant, a champion power conversion efficiency (PCE) of 25.22% based on EAP modification is achieved-one of the highest reported values for air-processed n-i-p PSCs-along with exceptional stability (e.g., 95.0% PCE retention after 4392 h storage, and 95% after 1000 h of MPPT at 40 ± 5°C and 40%-50% RH in air). This study provides valuable insights for the rational molecular design of interface engineering, enabling the fabrication of high-performance, long-lifetime PSCs in ambient air.
