Intramolecular Donor-Acceptor Regioregular Poly(hexylphenanthrenyl-imidazole thiophene) Exhibits Enhanced Hole Mobility for Heterojunction Solar Cell Applications

摘要

Conjugated polymers possessing extended arrays of delocalized it electrons are being investigated intensively for their potential use in organic optoelectronic devices, with some studies focused on solar-cell devices incorporating bulk heterojunctions using conjugated polymers. Polythiophene derivatives are at present among the most promising materials for solar-cell applications because of their high light absorption and electronic conductivity.
