Abstract:A strategically designed donor–acceptor (D‐A) block copolymer (PM6‐b‐PYIT) is introduced, as a compatibilizer to enhance the performance and stability of inverted organic solar cells (OSCs) consisting of a bulk heterojunction (BHJ) of PM6 and L8‐BO. The PM6‐b‐PYIT compatibilizer not only significantly boosts the power conversion efficiency from 16.32% to 18.02%, but also further modulates the molecular arrangement and improves the compatibility between donor and acceptor materials. This stems from the structur… Show more
