| Research Abstract |
The conversion efficiency of organic solar cells strongly depends on the morphology of the composites. In this study, in order to controll the morphology and the orientation of phase separated each domain, novel methodology utilizing block copolymers consisting of regioregular poly (3-hexylthiophene) (P3HT) and electrically inert polymer. The film morphology of the composites of block copolymers with fullerene derivative was strongly dependent on the nature of inert block. P3HT-b-polystyrene composite showed distinct and larger domain compared with P3HT/PCBM. On the other hand, P3HT-b-poly (ethylene oxide) showed smaller size of regular phase separated structure.
