A polyfluoroalkyl-containing guest acceptor (EH-C₈F₁₇) enables self-stratification in the active layer of bulk-heterojunction organic solar cells. The favorable vertical phase separation and molecular stacking increases the mobility, increases carrier lifetimes, and reduces trap-assisted recombination, leading to significantly improved device performance.
