Tetrathienoanthracene-based Copolymers for Efficient Solar Cells



Feng He, Wei Wang, Wei Chen, Tao Xu, Seth B. Darling, Joseph Strzalka, Yun Liu, Luping Yu


A series of semiconducting copolymers (PTAT-x) containing extended π-conjugated tetrathienoanthracene units have been synthesized. It was shown that the extended conjugation system enhanced the π-π stacking in the polymer/ PC61BM blend films and facilitated the charge transport in heterojunction solar cell devices. After structural fine-tuning, the polymer with bulky 2-butyloctyl side chains (PTAT-3) exhibited a PCE of 5.6% when it was blended with PC61BM.
