dc.description.abstract | Nonfullerene acceptors (NFAs) have played an important role in the development of organic solar cells. However, the optical absorption of most NFAs is limited within 600-900 nm, prohibiting further improvement of short-circuit current density (J(sc)). To alleviate this problem, a fused-ring pi-core BzS was designed by combining weakly electron-withdrawing benzotriazole (Bz) and strongly electron-donating selenophene together. Besides, the length of N-alkyl chain on the Bz moiety was engineered to tune the morphology, affording two NFAs mBzS-4F and EHBzS-4F. Both NFAs possess an absorption edge approaching 1000 nm, as resulted from the enhanced intramolecular charge transfer in conjunction with efficient intra- and intermolecular interactions. Binary photovoltaic devices based on PM6:mBzS-4F showed a power conversion efficiency of 17.02% with a very high J(sc) of 27.72 mA/cm(2) and a low energy loss of 0.446 eV. This work provides a strategy for future design of efficient NIR-responsive materials. | - |
