In this study, the well-defined coil−rod−coil triblock copolymer poly(4-vinyltriphenylamine)-b-poly(3-hexylthiophene)-b-poly(4-vinyltriphenylamin) (PTPA-P3HT-PTPA) was used as a surfactant for P3HT/PCBM (1:1) based solar cells. The power conversion efficiency of the device was enhanced from 3.9 to 4.4% in the presence of the 0−5% PTPA-P3HT-PTPA under illumination of AM 1.5G (100 mW/cm2). The morphology variation and the balance of the hole/electron mobility accounted for such enhancement. In the P3HT/ ...
