Linyi Bian, Dong Yang, Liangming Yin, Jian Zhang* and Weihua Tang*
An alternating conjugated polymer (PTCDPP) of carbazole-substituted triarylamine and diketopyrrolopyrrole is prepared with a bandgap of 1.66 eV. By using 1,8-diiodooctane(DIO) (3% v/v) as a processing additive and annealing the active layer at 80 °C, the best performing device PTCDPP:PCBM (1:4, w/w) exhibits a power coversion efficiency of 2.65%.
