摘要：

A new family of polythienothiophene-co-benzodithiophene copolymers with different amounts of fluorine decoration (PBFx) had been successfully synthesized. Detailed structure property investigations covering physical properties, morphology, and solar cell performance with respect to the fluorine content in the polymers were performed by a series of structural characterization techniques. A PCE of 8.75% was obtained with the highest fluorinated polymer; the morphological trends, as well as the crystalline structure, were also investigated, shedding light on this important material modification.
