An arylated‐carbazole conjugated polymer with a deep HOMO level has been developed. Solar cells based on blends of PCX3 and PC 71 BM show efficiency of 3.9% with a V oc of 0.96 V. The device performance can be improved to 5.1% by using polar solvent treatment, most likely as a result of modified interfacial properties.
