METHOD OF MANUFACTURING COUNTER ELECTRODE FOR DYE-SENSITIZED SOLAR CELL USING NITROGEN DOPED TITANIUM DIOXIDECARBON NANOFIBER COMPOSITE

摘要

The present invention relates to a nitrogen-doped titanium dioxide-carbon nanofiber composite material and a method for producing the same, and more particularly, to a titanium dioxide-carbon nanofiber composite material containing titanium dioxide, nitrogen-doped titanium dioxide, titanium nitride and carbon nanofibers, Wherein the doped titanium dioxide comprises 3.4 to 13.8 wt% of the carbon nanofibers and the nitrogen-doped titanium dioxide is an anatase phase. The nitrogen-doped titanium dioxide-carbon nanofiber composite and the carbon nanofiber precursor Dissolving the substance in a solvent, adding and dispersing the titanium dioxide nanoparticles to prepare a spinning solution; Preparing a titanium dioxide-carbon nanofiber composite by electrospunning the spinning solution; And carbonizing the resulting composite in a nitrogen atmosphere. The present invention also relates to a method for producing a nitrogen-doped titanium dioxide-carbon nanofiber composite.
