PDPP4T-2F, semiconducting polymer with deep HOMO level

High quality polymer available for fast, secure dispatch

| |

PDPP4T-2F is the fluorinated version of 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 V_oc due to its deeper HOMO energy level, PDPP4T-2F shows great potential in achieving a higher J_sc than PDPP4T in devices for its improved extinction coefficient.
