Recently,the power conversion efficiency(PCE) of polymer solar cells(PSCs) has reached 11 %,exhibiting avery bright future for practical applications.High efficiency PSCs are of a bulk heterojunction structure withthe conjugated polymer as the donor and(6,6)-phenyl-C61-butyric acid methyl ester(PC61BM) or(6,6)-phenyl-C71-butyric acid methyl ester(PC71BM) as the acceptor.
