Redox-Driven Spatiotemporal Passivation for Efficient andDurable Perovskite Solar Cells Here, we systematically screened a series of redox-active, bifunctional passivation molecules with various functional motifs, namely sildenafil (SDNF), avanafil (AVNF), and dabrafenib (DRFN), to achieve spatial defect passivation and temporal redox healing in perovskite films. 本文系统筛选了一系列具有不同功能基团的氧化还原活性双功能钝化分子，包括西地那非（SDNF）、阿伐那非（AVNF）和达拉非尼（DRFN），旨在实现钙钛矿薄膜的空间缺陷钝化和瞬态氧化还原修复。
