dc.description.abstract | The extension of fused aromatic ring core structures is beneficial for enhancing intramolecular charge transfer and effective pi conjugation in A-D-A-type (A=acceptor; D=donor) non-fullerene acceptors (NFAs). In this work, a novel strategy involving the extension of a fused-ring core by symmetrically replicating the core unit has been developed, and a novel symmetric fused-12-ring NFA, LC81, has been synthesized. When paired with the wide-bandgap polymer donor PBT1-C, the corresponding organic solar cells (OSCs) showed a high power conversion efficiency of 12.71 %, much higher than that of the device based on the reference NFA, TPTT-4F. Moreover, the LC81-based OSC displayed a lower energy loss and a better ambient stability than the TPTT-4F-based device. Our results indicate that the extension of the fused-ring core by the symmetric replicating core unit strategy is an effective approach to promoting the photovoltaic characteristics of A-D-A-type NFAs. | - |
