Solar cells based on a new conjugated donor polymer with alternating quaterthiophene and diketo pyrrolo-pyrrole units in combination with C60 and C70 PCBM acceptors afford high external quantum efficiencies over a broad spectral range into the near-infrared. The cells provide power conversion efficiencies of up to 4.0% under simulated AM1.5G solar light conditions.
