Graphical Abstract

Two dimeric acceptors , DIBP3F-Se and DIBP3F-S were synthesized by linking two Y6-derivative segments using different central linking bridges: selenophene and thiophene. Both adopt a favorable O-shape conformation as confirmed by simulations and 2D NMR spectroscopy. Paired with the state-of-the-art polymer donor PM6, optimized solar cells employing DIBP3F-Se showcase remarkable performance with a power conversion efficiency of 18.09 %, as demonstrated by Donghong Yu, Thomas D. Anthopoulos, Ergang Wang et al. in their Research Article (e202302888).
