Applications

Poly[2,5-bis(2-octyldodecyl)pyrrolo[3,4-c]pyrrole-1,4(2H,5H)-dione -3,6-diyl)-alt-(3'',4'-difluoro[2,2’;5’,2’’;5’’,2’’’-quaterthiophen]-5,5’’’-diyl)] (PDPP4T-2F) is the fluorinated version of PDPP4T with a device performance PCE of 7.59% [1].

In comparison to PDPP4T, PDPP4T-2F has a deeper highest-occupied molecular orbital (HOMO) level, due to the electron-withdrawing nature of the fluorine atoms on the thiophene units. It has also been reported that apart from being more favorable for realising higher Voc due to its deeper HOMO  energy level, PDPP4T-2F shows great potential in achieving a higher Jsc than PDPP4T in devices for its improved extinction coefficient.
