Abstract Organic solar cells (OSCs) have emerged as promising candidates for renewable energy harvesting due to their lightweight, flexible, and low‐cost fabrication potential. The efficiency of OSCs is largely determined by the choice solvents, which significantly affect film morphology active layers, intermixed donor‐acceptor domains, overall device performance. Beginning with an introduction importance solvent selection, screening classification emphasizing characteristics based on sustainability, solubility, other additional considerations are explored. Various non‐halogenated highlighting commonly used aromatic biomass‐derived water/alcohol‐based solvents state‐of‐the‐art donor acceptor materials, focusing efficient materials such PM6 D18, high‐performing Y‐series acceptors also presented. Strategies developing high‐performance processed using examined, including engineering additive additive‐free approaches, ternary strategies, layer‐by‐layer techniques. large‐area devices addressed, blade‐coating, slot‐coating, processing Finally, this review outlines future research directions in OSCs, need continuous innovation overcome existing limitations propel OSC technology toward commercial viability.

Abstract Blade coating is a promising tool for upscaling organic solar cells (OSCs). However, the performances of blade‐coated OSCs still lag behind their spin‐coated counterparts, limiting competitive edge towards commercialization. One main reasons that controlling film aggregation kinetics and morphology becomes challenging during transition from spin to blade coating, especially when using high boiling point solvents, which can result in excessive aggregation. Therefore, deeper understanding appraisal formation influenced by methods crucial. In this work, it demonstrated ink solubility tuning incorporating twisted third component (BTP‐4Cl) induce rapid crystallization behavior promote fine phase separation between donor polymer (PM6) acceptor (BTP‐eC9) coating. As result, power conversion efficiency (PCE) 19.67% obtained (0.04 cm 2 ), one state‐of‐the‐art efficiencies among reported (19.76% devices). addition, found inhibited contributes enhancing light stability device. This strategy offered novel insights into effectiveness solubility‐tuning approaches achieving highly efficient stable under open‐air conditions.
