We prepared Poly(vinylidenefluoride-co-hexafluoropropylene) (PVDF-HFP) nanofibers containing nano-sized inorganic BaTiO(3) filler by electrospinning technique, and applied to the dye sensitized solar cells (DSSCs). This technique compensates the draw back of leakage of the electrolyte in DSSCs. Moreover, electrospun PVDF-HFP nanofibers containing inorganic filler have better ionic conductivity than those of without filler, and the DSSC device using inorganic filler showed better efficiency than without inorganic filler. The best result of V(oc), J(sc), FF, and eta of the DSSC devices using the electrospun PVDF-HFP nanofibers containing 20 wt% inorganic BaTiO(3) filler were the values of 0.70 V, 12.9mA/cm(2), 0.58 and 5.15% under AM 1.5, respectively. We also measured up-take, ionic conductivity and porosity to investigate the effect of electrolyte in the electrospun nanofibers.
