Abstract

A novel D-A1-D-A2-type polymer that exhibits a small bandgap of 1.43 eV yet still yields polymer solar cells with a high open-circuit voltage (V_OC) of 0.81 V and power conversion efficiencies of up to 8.63% is reported. Comparable efficiencies can be achieved even when the active layer is processed in air or after it is thermally annealed at 150 °C.
