Porphyrin-containing D-π-A conjugated polymer with absorption over the entire spectrum of visible light and its applications in solar cells

In this communication, we present the first example of a donor-acceptor porphyrin-containing conjugated copolymer, PCTTQP, with absorption over the entire spectrum of visible light. The BHJ solar cells based on PCTTQP : PC71BM blends displayed a PCE of 2.5%, which is the highest value in porphyrin-based conjugated polymers.
