Abstract

Three isomeric FREAs were synthesized and applied in organic solar cells. The OSC devices based on Z1-bb exhibited a PCE of 12.66%. The isomerization of a fused-ring core could be achieve high-performance OSCs with high <italic>J</italic><sub>sc</sub>, <italic>V</italic><sub>oc</sub>, and FF.
