摘要：

Attaining a balanced charge carrier generation is a significant challenge in organic photovoltaics (OPVs). To enhance device performance, the ternary strategy has emerged as an effective approach. In this study, two Y6 derivatives, QIP-4F and QIP-4Cl, containing quinoxalineimide (QI) building blocks fused with thienylthiophene as the central unit were incorporated into the PM6:L8-BO system. The quinoxalineimide units reduce the energy losses in charge carrier extraction and non-radiative charge recombination. Furthermore, the increasing steric hindrance in the central block impacts phase separ...
