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 is a conjugated block copolymer lacking a wide bandgap donor and a narrow bandgap acceptor block, in which different p- type semiconductor blocks and n- type semiconductor blocks are each covalently connected, and includes the same. It relates to a single component organic solar cell, wherein the conjugated block copolymer according to the present invention has a deep HOMO level, a small band gap, and a high charge mobility, and thus can exhibit excellent efficiency of an organic solar cell. It can be used alone in a solar cell to further improve the lifespan characteristics of the device due to the excellent stability of the compound.
