Title: The Curious Case of Fluorination of Conjugated Polymers for Solar Cells

Conjugated polymers with fluorine substitutions have shown significantly improved device performance than their non-fluorinated counterparts.¹ Though significant advances on the fundamental understanding of the effect of fluorination have been achieved,² there still remain questions to be answered.

In this talk, we will try to summarize the recent understanding on the effect of fluorination on conjugated polymers. A few newly synthesized fluorinated polymers will be discussed in detail to shed more light on understanding this peculiar effect of fluorination.^3,4
