Abstract

Three terpolymers, J1, J2 and J3, were developed via a ternary polymerization strategy. J2 with 5% ITIC possesses suitable complementary absorption, matching energy levels, especially the appropriate aggregation behaviour and improved compatibility between J2 and PM6 to offer an excellent power conversion efficiency of up to 16.48%.
