| Research Abstract |
For the improvement of the efficiency for photon-electron conversion process in polymer thin film solar cells, it is important to create a suitable phase-separated structure in the active layer. In this work, multi-functional block copolymers were designed and synthesized in order to utilize the self-assembling nature of block copolymers for the construction of well-controlled phase-separated morphology in the active layer of the solar cells. Introducing a functional group fostering smooth charge dissociation at the junction of polythiophene-based block copolymers provided fine phase separations in the blend film with a fullerene derivative. The photon-electron conversion efficiency was improved for the solar cell devices based on the junction-modified block copolymers compared to the conventional devices.
