o-Chlorobenzaldehyde (CBA) is a derivative of chlorobenzene (CB). The boiling point of CBA is 212 °C, much lower than 332 °C for 1,8-diiodooctane (DIO). With CBA as solvent additive in CB host solvent, CBA could be fast removed during spin-coating 100, 200, and 300 nm thick thieno[3,4-b]thiophene/benzodithiophene polymer (PTB7):[6,6]-phenyl C71-butyric acid methyl ester (PC71BM) active layers, achieving power conversion efficiencies of 9.11%, 8.24%, and 7.11%, respectively, much higher than 7.53%, 5.71%, and 4.93% for corresponding DIO control devices with vacuum drying.
