title: Polymer solar cells with diketopyrrolopyrrole conjugated polymers as the electron donor and electron acceptor.
abstract: A new class of diketopyrrolopyrrole conjugated acceptor polymer incorporating thiazoles with low-lying energy levels, high electron mobility, and broad absorption to the near infrared region provides a power conversion efficiency of 2.9% in solar cells with a second diketopyrrolo-pyrrole polymer as the donor.
