However, conventional SAMs such as Me\u20104PACz tend to adopt lying\u2010down or tilted conformations on substrates, leading to disordered dipole orientation, inadequate substrate coverage, and buried terminal groups that are unable to passivate interface defects. In this study, we design an asymmetric conjugated SAM molecule, BCPA\u2010Ph, to address these limitations. Its vertically oriented \u03c0\u2010conjugated backbones build direct hole transport pathways, thereby accelerating carrier extraction, while the fully exposed terminal carbazole N\u2500H groups form intermolecular hydrogen bonds with perovskite surface iodine species and eliminate iodide vacancy traps. As a result, the inverted PSCs based on BCPA\u2010Ph achieve a certified power conversion efficiency (PCE) of 27.21%, along with markedly enhanced thermal and operational stability. Moreover, BCPA\u2010Ph presents outstanding universality for large\u2010area and wide\u2010bandgap perovskite devices, yielding a high PCE of 26.34% for 1 cm\n                    <jats:sup>2<\/jats:sup>\n                    devices and 23.77% for 1.68\u00a0eV wide\u2010bandgap PSCs. This work underscores the critical importance of molecular configuration engineering in the rational design of SAMs for high\u2010performance PSCs.\n                  <\/jats:p>","DOI":"10.1002\/adma.75147","type":"journal-article","created":{"date-parts":[[2026,9,25]],"date-time":"2026-09-25T06:17:02Z","timestamp":1790317022000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Upright Orientation of Asymmetric Conjugated SAM Enables High\u2010Performance Perovskite Solar Cells"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-3370-7252","authenticated-orcid":false,"given":"Xinyu","family":"Gu","sequence":"first","affiliation":[{"name":"Future Photovoltaics Research Center Global Institute of Future Technology (GIFT) Shanghai Jiao Tong University  Shanghai P.
