Highlights A novel fluoro-methoxylated end group for Y-series acceptors is produced, and asymmetric substitution strategy is applied as a step-by-step optimization. 19.24% power conversion efficiency is achieved for industrially compatible solvent ortho-xylene processed organic solar cells. Underlying morphological and photo-physical variation is revealed for device performance difference brought by solvent selection, which could set up a template for future research on similar topics.
