Synthesis and organic photovoltaic applications of fully conjugateddonor-acceptor diblock copolymers

合成了完全共轭的供受体嵌段共聚物作为非富勒烯受体材料的候选材料。所得嵌段共聚物具有良好的受体和广泛的捕光性能。以聚（3-己基噻吩）和得到的嵌段共聚物分别作为供体和受体材料制备活性层的全聚合物太阳能电池的功率转换效率为1.6%。这些结果表明，完全共轭的供-受体嵌段共聚物作为非富勒烯受体材料具有巨大的潜力。

Fully conjugated donor-acceptor block copolymers were synthesized for the candidate of non-fullerene acceptor materials. The obtained block copolymers showed the good acceptor and wide light-harvesting properties. The all-polymers solar cells, in which the active layers were respectively prepared from poly(3-hexylthiophene) and the obtained block copolymers as donor and acceptor materials, achieved the power conversion efficiency of 1.6%. These results demonstrated that fully conjugated donor-acceptor block copolymers had a huge potential for the non-fullerene acceptor material.
