Abstract

Abstract Fluorination of the donor and/or acceptor blocks of photoactive semiconducting polymers is a leading strategy to enhance organic solar cell (OSC) performance. Here, the effects are investigated in OSCs using fluorine‐free ( TPD‐3 ) and fluorinated ( TPD‐3F ) donor polymers, paired with the ...
