Original abstract
ABSTRACT Self‐assembled materials (SAMs) represent an emerging class of hole‐selective contact materials for inverted perovskite solar cells (PSCs). In this work, we report a multifunctional SAM named T4 for regulating the buried FTO/SAM/perovskite interface. T4 combines a phosphonic‐acid anchoring group with a heteroatom‐incorporated fused aromatic terminal group, enabling coupled interfacial effects including improved SAM loading/packing, interfacial electronic‐structure modulation, and sulfur‐involved interaction with Pb‐containing species. These combined effects improve the buried‐interface quality, suppress interfacial recombination losses, and promote hole‐selective charge collection. Consequently, T4‐based inverted PSCs achieve a champion power conversion efficiency of 26.67% and retain approximately 90% of their initial efficiency after 800 h of continuous maximum power point tracking. This work highlights the potential of multifunctional SAM design for regulating buried interfaces in efficient and stable perovskite photovoltaics.
