Conjugated block copolymers comprising with donor type block and acceptor type block single-component polymer solar cell using the same

摘要

The present invention relates to: a conjugated-type block copolymer having a wide bandgap donor and a narrow bandgap acceptor block in which p-type semiconductor blocks and n-type semiconductor blocks are covalently connected, respectively; and a single component organic solar cell. The conjugated-type block copolymer according to the present invention has a deep HOMO level, a small band gap, and a high charge mobility, thereby exhibiting excellent efficiency of an organic solar cell. In addition, by using the block copolymer alone in the organic solar cell, it is possible to further improve lifespan characteristics of a device due to excellent stability of a compound.
