Side-chain fluorination of polymers is demonstrated as a highly effective strategy to improve the efficiency all-polymer solar cells from 2.93% (nonfluorinated P1) 7.13% (fluorinated P2). This significant enhancement achieved by synergistic improvements in open-circuit voltage, charge generation, and transport, donor polymer optimizes band alignment film morphology.
