PNF222PNF222, polymer acceptor for all-PSCs and OFETs
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.
