A novel, solution-processable non-fullerene electron acceptor displayed excellent solubility, thermal stability, and afforded 2.30% power conversion efficiency with a high open-circuit voltage (1.17 V).
A novel, NDI-based non-fullerene electron acceptors (R1, R2) for solution-processable bulk-heterojunction, displayed good thermal stability and afforded 2.24% power conversion efficiency.
