Self-assembled monolayer molecules have been widely employed as interfacial transport materials in inverted perovskite solar cells (PSCs), demonstrating high efficiency and improved device stability. However, self-assembling (SAM) often suffer from aggregation weak interactions with the layer, resulting inefficient charge transfer significant energy losses, ultimately limiting power conversion long-term stability of cells. In this work, we developed a series novel skeleton-matching carbazole isomer SAMs based on following key design principles: (1) introducing benzene ring structure to distort molecular skeleton SAM, thereby preventing achieving uniform distribution fluorine-doped tin oxide (FTO) substrates; (2) strategically incorporating methoxy groups onto at different positions (ortho, meta, para). These functional not only increase anchoring points layer but also fine-tune dipole moment. Among SAMs, m-PhPACz exhibits most favorable properties, maximum moment 2.4 D an O-O distance that aligns excellently diagonal lead ions adjacent lattice, enhancing SAM-perovskite interactions, facilitating efficient extraction, improving As result, new SAM-based PSCs achieved impressive 26.2%, 12.9% improvement. Moreover, devices demonstrated outstanding photothermal stability, retaining 96% their initial PCE after 1000 h 85 °C maintaining 90% 300 UV-light exposure.
