BTR-Cl belongs to BTR derivative, which is a small molecule donor with high crystallinity, strong self-assembly, and high mobility. It has the disadvantages of excessive crystallization and inferior film morphology. However, incorporating of the novel PBTz-F in the preparation of photovoltaic devices can improve this shortcoming[1-2].
