Two novel selenophene-containing building blocks have been developed as central cores to construct high-performance asymmetric non-fullerene acceptors (SePTT-2F and SePTTT-2F). Organic solar cells based on SePTTT-2F with more extended backbone conjugation delivered a high efficiency of 12.24% with an outstanding fill factor of 75.9%.
