title: A random copolymer based on dithienothiophene and diketopyrrolopyrrole units for high performance organic solar cells.
abstract: A random donor-acceptor semiconducting copolymer based on diketopyrrolopyrrole as the acceptor unit and dithienothiophene as the donor unit has been synthesized and characterized. Preliminary studies of BHJ solar cells based on this polymer with PC(71)BM showed a high PCE of above 5% under 100 mW cm(-2) AM1.5 solar illumination.
