PBDB-T-SF is a fluorinated wide-bandgap polymeric donor (n-type semiconductor) with relatively deep highest occupied molecular orbital (HOMO) energy level. It has been used in high performance polymer organic solar cells (PSCs).
HOMO =−5.40eV
LUMO =−3.60eV
Polymer organic solar cells (PSCs) device performance:
Device based on PBDB-T-SF:NCBDT-4Cl
Before any post-treatment
PCE= of 13.1%
After device optimizations
Voc = 0.85V
Jsc = 2.35 mA /cm2
FF = 74.3%
PCE >14%
Energy loss = 0.55 eV
The improved performance was attributed to the more efficient photo-electron conversion process in the optimal device.
Device performance based on PBDB-T-SF:ITIC-F as active layer
(ITO)/ZnO/active layer/MoO3/Al
Voc = 0.88 V
Jsc = 20.50 mA/cm2
FF = 71.9%
PCE = 13.1%
Energy loss = 0.66 eV
