A novel solution-processable electron acceptor based on diketopyrrolopyrrole and benzothiadiazole building blocks was designed and synthesized, which exhibited excellent solubility and thermal stability, and afforded 1.16 power conversion efficiency with high open-circuit voltage (1.08 V) when tested with the classical poly(3-hexylthiophene) electron donor in bulk-heterojunction solar cells. The open-circuit voltage reported here ( 1.1 V) is among the highest values for a single bulk-heterojunction device.
