Abstract

original image

A low band gap alternative polymer was synthesized. The polymer contained benzodithiophenes with lateral thiophenes and fluorinated benzothiadiazole. The polymer possessed broad absorption and high Voc. The PCE of the device with PC61BM achieved 4.8% without annealing and additive.
