It has been claimed that both \u03c0\u2010electrons within aromatic units and carbonyl groups can, separately, interact with ionic defects, which, however, causes troubles in understanding the passivation mechanism of those aromatic ketone\/aldehyde molecules. Herein, we clarify the effect of both moieties in one molecule on the defect passivation by investigating three aromatic aldehydes with varied conjugation planes, namely, biphenyl\u20104\u2010carbaldehyde (BPCA), naphthalene\u20102\u2010carbaldehyde (NACA) and pyrene\u20101\u2010carbaldehyde (PyCA). Our findings reveal that the \u03c0\u2010electrons located in the conjugated system do not directly present strong passivation for defects, but enhance the electron cloud density of the carbonyl group augmenting its interaction with defect sites; thereby, with the extended conjugation plane of the three molecules, their defect passivation ability is gradually improved. PSCs incorporating PyCA with the most extended \u03c0\u2010electrons delocalization achieve maximum power conversion efficiencies of 25.67\u2009% (0.09\u2005cm\n                    <jats:sup>2<\/jats:sup>\n                    ) and 21.76\u2009% (14.0\u2005cm\n                    <jats:sup>2<\/jats:sup>\n                    ). Moreover, these devices exhibit outstanding long\u2010term stability, retaining 95\u2009% of their initial efficiency after operation for 1000\u2005hours at the maximum power point.\n                  <\/jats:p>","DOI":"10.1002\/anie.202420369","type":"journal-article","created":{"date-parts":[[2024,12,12]],"date-time":"2024-12-12T21:58:48Z","timestamp":1734040728000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Insights Into the Role of \u03c0\u2010Electrons of Aromatic Aldehydes in Passivating Perovskite Defects"],"prefix":"10.1002","volume":"64","author":[{"given":"Xiaoqing","family":"Jiang.","sequence":"first","affiliation":[{"name":"College of Chemical Engineering Qingdao University of Science and Technology  Qingdao 266042 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lina","family":"Zhu","sequence":"additional","affiliation":[{"name":"College of Chemical Engineering Qingdao University of Science and Technology  Qingdao 266042 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5657-6303","authenticated-orcid":false,"given":"Bingqian","family":"Zhang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Photoelectric Conversion and Utilization of Solar Energy Qingdao New Energy Shandong Laboratory Qingdao Institute of Bioenergy and Bioprocess Technology Chinese Academy of Sciences  Qingdao 266101 China"},{"name":"College of Materials Science and Engineering Qingdao University of Science and Technology  Qingdao 266042 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangyue","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Chemical Engineering Qingdao University of Science and Technology  Qingdao 266042 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Likai","family":"Zheng","sequence":"additional","affiliation":[{"name":"Laboratory of Photonics and Interfaces \u00c9cole Polytechnique F\u00e9d\u00e9rale de Lausanne  CH-1015 Lausanne Switzerland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaiwen","family":"Dong","sequence":"additional","affiliation":[{"name":"College of Chemical Engineering Qingdao University of Science and Technology  Qingdao 266042 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yanfeng","family":"Yin","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Molecular Reaction Dynamics Dalian Institute of Chemical Physics Chinese Academy of Sciences  Dalian 116023 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Minhuan","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Materials Modification by Laser, Ion, and Electron Beams Ministry of Education) School of Physics Dalian University of Technology  Dalian 116024 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shiwei","family":"Liu","sequence":"additional","affiliation":[{"name":"College of Chemical Engineering Qingdao University of Science and Technology  Qingdao 266042 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2526-4104","authenticated-orcid":false,"given":"Shuping","family":"Pang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Photoelectric Conversion and Utilization of Solar Energy Qingdao New Energy Shandong Laboratory Qingdao Institute of Bioenergy and Bioprocess Technology Chinese Academy of Sciences  Qingdao 266101 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Guo","sequence":"additional","affiliation":[{"name":"Key Laboratory of Photoelectric Conversion and Utilization of Solar Energy Dalian Institute of Chemical Physics Chinese Academy of Sciences  Dalian 116023 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,12,27]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-022-04961-1"},{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1039\/D2EE02543D"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41560-024-01471-4"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-021-03964-8"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41566-024-01468-1"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.1002\/aenm.202400078"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/anie.202314270"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/adfm.202309789"},{"key":"e_1_2_7_9_1","doi-asserted-by":"crossref","unstructured":"X.\u2005Y.
