ABSTRACT
Poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) nanofibers containing inorganic fillers were fabricated by electrospinning. Dye-sensitized solar cells (DSSCs) using these nanofibers showed improved short circuit currents without degraded fill factors or open circuit voltages. The long-term stabilities of cells using electrospun PVDF-HFP/titanium isopropoxide (TIP) nanofibers were significantly improved.

We prepared electrospun polymer nanofibers by electrospnning method and investigated about their applications to dye-sensitized solar cells (DSSCs). Electrospun polymer nanofibers applied to the polymer matrix in electrolyte for DSSCs. To improve the stiffness of polymer nanofiber, poly(vinylidene fluoride-hexafluoro propylene)/Poly(methyl methacrylate) (PVDF-HFP/PMMA) blend nanofibers were prepared and examined. In the electrospun PVDF-HFP/PMMA (1:1) blend nanofibers, the best results of VOC, JSC, FF, and efficiency of the DSSC devices showed 0.71 V, 12.8 mA/cm2, 0.61, and 5.56% under AM 1.5 illumination.
