Abstract Solution‐processable organic solar cells (OSCs) represent a promising renewable photovoltaic technology with significant potential for eco‐compatible production. While high power conversion efficiencies (PCEs) have been achieved in OSCs, scaling this high‐throughput manufacturing remains challenging. Key reason lies the lack of efficient control strategies complex and long‐duration morphology evolution during high‐speed coating process ecofriendly solvents. Here, donor‐priority rapid aggregation (DP‐RAP) scheme is proposed to solve issue by adjusting kinetics donor acceptor components. DP‐RAP enables blends nanoscale fiber network structure favorable crystallinity, which contributes balanced carrier transport reduced recombination losses. As result, PCE improved from 14.3% (reference) 17.4% ultra‐high speed coated PM6:BTP‐eC9 devices atmosphere, one highest values non‐halogenated solvent‐processed at speeds 500 mm s −1 . Moreover, based remain stable approximately across broad range (20–500 ), illustrating its tolerance varied conditions. This work highlights avenue high‐speed, production pushing boundaries practical energy technologies.
