In this study, we introduce volatile solid additives to regulate intermolecular interactions and improve blending miscibility, thereby controlling aggregation and phase separation. Both computational and experimental results reveal that the key to this regulation lies in the strong electrostatic potential coupling between the solid additive and the polymer acceptor. This selective interaction modulates the aggregation behavior during film deposition and thermal annealing, enabling a gradual phase evolution. Further analysis indicates that the strong electrostatic coupling reduces aggregate size and promotes more ordered molecular packing, ultimately optimizing the film morphology. As a result, all\u2010PSCs based on PM6\/PY\u2010IT incorporating the solid additive 2\u2010BDBF exhibit a significantly improved power conversion efficiency of 18.62%, representing an increase compared to 14.93% ender the control conditions. This work demonstrates that solid additives with engineered electrostatic interactions offer an effective strategy to tune intermolecular forces, optimize morphology evolution, and boost device performance in all\u2010PSCs.<\/jats:p>","DOI":"10.1002\/smtd.202501821","type":"journal-article","created":{"date-parts":[[2026,2,16]],"date-time":"2026-02-16T04:48:41Z","timestamp":1771217321000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Tuning Intermolecular Interactions With Solid Additives to Optimize Molecular Aggregation and Molecular Packing in All\u2010Polymer Solar Cells"],"prefix":"10.1002","volume":"10","author":[{"given":"Luzhuo","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory of Polymer Science and Technology Changchun Institute of Applied Chemistry Chinese Academy of Sciences  Changchun China"},{"name":"School of Applied Chemistry and Engineering University of Science and Technology of China  Hefei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanyue","family":"Gao","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Polymer Science and Technology Changchun Institute of Applied Chemistry Chinese Academy of Sciences  Changchun China"},{"name":"School of Applied Chemistry and Engineering University of Science and Technology of China  Hefei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Shen","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Polymer Science and Technology Changchun Institute of Applied Chemistry Chinese Academy of Sciences  Changchun China"},{"name":"School of Applied Chemistry and Engineering University of Science and Technology of China  Hefei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingyu","family":"Zuo","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Polymer Science and Technology Changchun Institute of Applied Chemistry Chinese Academy of Sciences  Changchun China"},{"name":"School of Applied Chemistry and Engineering University of Science and Technology of China  Hefei China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianbin","family":"Zhong","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronic Engineering Harbin Engineering University  Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jingyi","family":"Ren","sequence":"additional","affiliation":[{"name":"Key Laboratory of Automobile Materials and School of Materials Science and Engineering Ministry of Education Jilin University  Changchun China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhongxiang","family":"Peng","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Polymer Science and Technology Changchun Institute of Applied Chemistry Chinese Academy of Sciences  Changchun China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xianshao","family":"Zou","sequence":"additional","affiliation":[{"name":"College of Physics and Optoelectronic Engineering Harbin Engineering University  Harbin China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qiang","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Polymer Science and Technology Changchun Institute of Applied Chemistry Chinese Academy of Sciences  Changchun China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tonghui","family":"Wang","sequence":"additional","affiliation":[{"name":"Key Laboratory of Automobile Materials and School of Materials Science and Engineering Ministry of Education Jilin University  Changchun China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1008-5832","authenticated-orcid":false,"given":"Rui","family":"Zhang","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Bioinspired Interfacial Materials Science Institute of Functional Nano &amp;
