Solid additive engineering is a well-established and effective strategy for enhancing active layer morphology in polymer solar cells (PSCs), thereby improving their power conversion efficiency (PCE). However, the availability of solid molecules remains limited, especially those combining simple structural units with large dipole moment to promote strong interactions materials. In this study, we introduce 4-iodobenzonitrile (IBZN), commercially available, low-cost, structurally molecule high (3.33 debye), as PSCs. Theoretical calculations, ultraviolet–visible (UV-Vis) spectroscopy experiments, analysis demonstrate that IBZN forms L8-BO, subsequently packing mode crystallization. The incorporation into PM6:L8-BO-based PSCs resulted an increased fill factor (FF) 79.54% boosted PCE from 17.49% 18.77%. Furthermore, has also demonstrated outstanding regulatory effects systems based on other Y-series acceptors, such Y6 BTP-ec9. This study not only introduces characterized by but offers valuable insights subsequent development novel additives aimed at
