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.

Incorporating a third component through ternary copolymerization strategy has proven to be promising and effective approach for further improving the device performance of polymer donors. However, terpolymer donors typically exhibit negative effects on molecular stacking weaken charge transport due irregular distribution skeleton. Herein, two terpolymers PBBQ-5 (5% ff-Qx) PBBQ-10 (10% are developed by introducing difluoro-2-(3-hexyldecyloxy) quinoxaline (ff-Qx) main chain PM6. The introduction ff-Qx unit not only enables possess N···S noncovalent intramolecular interactions that contribute enlarge planarity enhance interaction but also can fine-tuning electrostatic potential (ESP) values related polymers, thereby regulate intermolecular with acceptor force. After blending L8-BO, PBBQ-5:L8-BO-based blend film exhibits appreciated miscibility, desirable phase separation sizes, more ordered packing than analogs. Consequently, an impressive power conversion efficiency (PCE) as high 19.54% is realized in PBBQ-5-based devices, which set new record Qx-based solar cells. work emphasizes drawbacks provides pathway developing high-performance optimizing intra/inter-molecular interaction.
