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 diketopyrrolopyrrole polymer as the donor.
