Application

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 =−5.40eVLUMO =−3.60eVPolymer organic solar cells (PSCs) device performance:Device based on PBDB-T-SF:NCBDT-4ClBefore any post-treatmentPCE= of 13.1¯ter device optimizationsVoc = 0.85VJsc = 2.35 mA /cm²FF = 74.3%PCE >14%Energy loss = 0.55 eVThe 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/AlVoc = 0.88 VJsc = 20.50 mA/cm²FF = 71.9%PCE = 13.1%Energy loss = 0.66 eV
