제목 Fabrications of PVA (Poly Vinyl Alcohol) Nanofibers by Electrospinning Technique and its Application to Dye-Sensitized Solar Cells
초록 We fabricated PVA (poly vinyl alcohol) nanofibers by electrospinning method and applied to the polymer matrix on the dye sensitized solar cells (DSSCs). This method compensates the draw back of leak of the electrolyte in the DSSCs. Photovoltaic characteristics were measured by using a Solar Simulator with a black mask under AM 1.5. The photovoltaic performance of the DSSC without the electrospun nanofiber was lower than those of electrospun nanofiber. We examined Electronical Impedance Spectroscopy (EIS) to evaluate the effective of the nanofibers in DSSC. Also, we examined the electrolyte up-take, the ionic conductivity, the porosity and SEM images to investigate the effect of electrolyte in the electrospun PVA nanofibers on DSSCs.
