CHLORO-BENZOTHIADIAZOLE-CONTAINING CONJUGATED POLYMER AND PREPARATION METHOD THEREFOR AND ORGANIC SOLAR CELL DEVICE

摘要

A chloro-benzothiadiazole-containing conjugated polymer, a preparation method therefor and an organic solar cell device. The chloro-benzothiadiazole-containing conjugated polymer is represented by structural formula (1), wherein Ar is one selected from structural formulas (A), (B), (C), (D), (E), (F), -OR1 and –SR1; R1 is an alkyl group having 1-20 carbon atoms; R2 is an alkyl group having 1-20 carbon atoms; and n is an integer between 1 and 50. The chloro-benzothiadiazole-containing conjugated polymer has higher energy conversion efficiency.
