“Ternary blending” and “random terpolymerization” strategies have both proven effective for enhancing the performance of organic solar cells (OSCs). However, reports on combination two remain rare. Here, a terpolymer PM6-Si30 was constructed by inserting chlorine alkylsilyl-substituted benzodithiophene (BDT) unit (0.3 equivalent) into state-of-the-art polymer PM6. The exhibitsadeep highest-occu...
