Terpolymer Donor with Inside Alkyl Substituents on Thiophene π‐Bridges toward Thiazolothiazole A2‐Unit Enables 18.21% Efficiency of Polymer Solar Cells
Abstract PM6 is a widely used D–A copolymer donor in the polymer solar cells (PSCs). Incorporating second electron‐withdrawing (A2) units into PM6 backbone by ternary D–A1–D–A2 random copolymerization strategy is an effective approach to further improve its photovoltaic performance.
