Fabrications of electrospun nanofibers containing inorganic fillers for dye-sensitized solar cells.

: 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.
