Ternary copolymerization has been proven to be an effective method regulate the photovoltaic properties of polymer donors. However, terpolymers synthesized using ternary strategy inevitably disrupt periodic sequence distribution backbone, resulting in increased molecular disorder and heightened main-chain entropy. Herein, we developed two terpolymer donors by introducing electron-deficient fused-ring skeleton unit BTP with a large dipole moment into main chain PM6 via copolymerization. We found that presence enables exhibit enhanced crystallinity electrostatic potential, leading excellent miscibility more ordered packing than PM6. As result, maximum PCE 19.40% was achieved for PY5:L8-BO-based device. Overall, this work introduces novel approach developing high-performance combining third component moments restrain enhance intermolecular interaction force between acceptors.
