Co-assembled self-assembled monolayers (co-SAMs) offer an effective route to enhance hole extraction. However, their practical design is limited by the absence of universal material selection rules, often leading to incompatible molecular packing and suboptimal interfaces. Here, we propose a synergistic co-SAM strategy that enables high-quality hole-selective contacts across OSCs, PSCs, and TSCs. By co-assembling carbazole-based phosphonic acids with chain length-matched phosphonic acid derivatives, we reveal that rational molecular pairing governs the synergistic behavior of co-adsorbates. PAC<sub>2</sub>Br shows optimal compatibility with 2PACz, while PAC<sub>4</sub>Br matches well with 4PACz, resulting in homogeneous molecular distribution, compact surface coverage, and favorable energy-level alignment. These synergistic interfaces effectively suppress interfacial recombination and enhance charge extraction. Consequently, co-SAM-modified devices achieve power conversion efficiencies of 19.60% in OSCs. Demonstrating the universality of the co-SAM strategy, the co-SAM pairing yields PSCs with efficiencies up to 25.78%, and further enables a champion PCE of 26.06% for perovskite/organic TSCs. This work establishes synergistic co-SAMs as a general and effective interfacial design principle for high-efficiency photovoltaic devices.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"1 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2026-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147753400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We further elucidate the correlation between SEI components and its solubility, and quantify that the average capacity loss caused by the dissolution of organic‐rich SEI is 1.36 times that of inorganic‐rich SEI.
