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.
