Abstract
Abstract The strategic utilization of self‐assembled monolayers (SAMs) significantly advances the interfacial contact and power conversion efficiency (PCE) of inverted perovskite solar cells (IPSCs). However, inadequate adhesion between the SAM and perovskite layer remains a critical challenge, limiting further performance enhancement. Herein, a synergistic interface engineering strategy is introduced that combines a co‐assembly approach with in situ polymerization to optimize the buried interface of perovskite film. Specifically, 11‐Mercaptoundecylphosphoric acid (MPA) is incorporated into a SAM to form co‐SAMs, improving homogeneity and mitigating defects at the NiO x surface. Simultaneously, the ionic…
