Buried Interface Engineering: a Key to Unlocking the Potential of Self‐Assembled Monolayer (SAM)‐Based Inverted Perovskite Solar Cells

Abstract P‐i‐n perovskite solar cells (PSCs) are regarded as a promising solution for mitigating global energy crises, owing to their exceptional stability and minimal hysteresis effects. In recent years, self‐assembled monolayer (SAM)‐based p‐i‐n PSCs have demonstrated power conversion efficiencies (PCEs) ≈27%. In contrast to existing reviews centered on SAM molecular structure modulation, this work prioritizes recent advancements in buried interface engineering for SAM‐based inverted PSCs. First, through a comprehensive analysis of the literature, eight distinct buried interface engineering strategies are defined, and elucidate their underlying mechanisms. Next, recent advancements in stability research specific to SAM‐based inverted PSCs are methodically synthesized. Finally, strategic recommendations are proposed to optimize device efficiency, stability, and scalable commercialization.
