Conjugation Pathway of Benzobisoxazoles in Polymer Donors Mediates the Charge Management and Enables Organic Solar Cells with Record Certified Efficiency

open access: yesAdvanced Materials, EarlyView.
Herein, the conjugation pathway isomerism of the benzobisoxazole (BBO) building block is systematically compared, by which a certified efficiency of 19.1% is obtained in corresponding all‐polymer solar cells. Abstract Charge management plays a pivotal role in achieving high‐performance bulk heterojunction (BHJ) organic solar cells (OSCs). In this study,
