PNF222, poly[[1,2,3,6,7,8-hexahydro-2,7-bis(2-octyldodecyl)-1,3,6,8-tetraoxobenzophenanthroline-4,9-diyl](3,3'-difluoro[2,2'-bithiophene]-5,5'-diyl)], is commonly used as polymer acceptor in all polymer solar cells or OFETs material.
Compared to PNDI(2OD)2T, with the introduction of the fluorine atoms on the electronic structure of the polymer, PNF222 has lower electronic energy levels due to the strong electronegativity of its fluorine atoms. In turn, this results in higher Voc, Jsc and FF for OPV devices.
It has also been reported that PCE of Si-PEDOT:PSS solar cells was promoted from 12.6% to 14.5% while a PNF222 polymer interlayer was incorporated, with the polymer orientation playing a critical role on the polymer–Si contact quality .
