pbdb-t-sf chemical structure, pce13

PBDB-T-SF, also known as PCE13, is a polymer donor semiconductor material used in highly-efficient OPV devices, such as non-fullerene polymer solar cells (NF-PSCs) and all-polymer solar cells (all-PSCs).

Compared to PBDB-T (PCE12), PBDB-T-SF has deeper HOMO (-5.4 eV) and LUMO (-3.6 eV) energy levels. This is due to fluorination, which produces an electron-withdrawn effect without causing strong steric hindrance. Fluorination can also enhance either intermolecular and/or intramolecular interactions - thus improving film crystallinity and facilitating charge transport.

Higher maximum absorption coefficiency has also been observed for PBDB-T-SF.
