CONDUCTING POLYMER INCORPORATING WITH PYRENE COMPOUND AND ORGANIC SOLAR CELL USING THEM

摘要

PURPOSE: A conducting polymer including a pyrene compound is provided to improve charge transfer velocity, thereby improving power conversion efficiency when used as an electron donor of an organic solar cell. CONSTITUTION: A conducting polymer including a pyrene compound is represented by chemical formula 1. In chemical formula 1, I is 0.40<= l/(l+m+n) < 1 as a molar fraction of X; m is 0 <= m/(l+m+n) <= 0.50 as a molar fraction of Y; n is 0 < n/(l+m+n) <= 0.10 as a molar fraction of the pyrene compound; X and Y are electron donors, acceptors or one monomer having optical absorption function.
