摘要

While varying the size and branching of solubilizing side chains in π-conjugated polymers impacts their self-assembling properties in thin-film devices, these structural changes remain difficult to anticipate. This report emphasizes the determining role that linear side-chain substituents play in poly (benzo [1, 2-b: 4, 5-b′] dithiophene–thieno [3, 4-c] pyrrole-4, 6- dione)(PBDTTPD) polymers for bulk heterojunction (BHJ) solar cell applications. We show ...
