Post-deposition treatment of an arylated-carbazole conjugated polymer for solar cell fabrication.
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.
