Nanofibril Formation of Electrospun TiO2 Fibers and its Application to Dye-Sensitized Solar Cells

Electrospun TiO 2 nanofibers were employed to the quasi-solid state dye-sensitized solar cells with porous electrodes, which enhanced the penetration of viscous polymer gel electrolytes. The morphology of electrospun TiO 2 fibers was affected by the electrospinning parameters such as the types of po...

Summary:Electrospun TiO 2 nanofibers were employed to the quasi-solid state dye-sensitized solar cells with porous electrodes, which enhanced the penetration of viscous polymer gel electrolytes. The morphology of electrospun TiO 2 fibers was affected by the electrospinning parameters such as the types of polymers, the concentration of polymer and titanium(IV) propoxide (TiP), the ratio of TiP/PVAc. The TiO 2 fibers electrospun from poly(vinyl acetate) matrix formed the one-dimensionally aligned fibrillar morphology as an islands-in-a-sea structure. The new TiO 2 electrodes demonstrated that the photocurrent generation with polymer gel electrolytes was over 90% of the performance in a dye-sensitized solar cell with liquid electrolytes.
