Mesoporous bragg stack electrodes, dye-sensitized solar cells comprising the same and method of fabrication thereof

摘要

The present invention relates to a Bragg-stacked electrode prepared by alternately laminating two layers having different refractive indexes selected from among a plurality of mesoporous titanium dioxide layers having different refractive indexes and a silicon dioxide layer, a method for producing the same, and a dye- , The electrode of the Bragg stack structure according to the present invention has a uniform surface structure, a large surface area and a well-aligned mesopore structure, and has excellent optical characteristics. In addition, when applied as an electrode of a dye-sensitized solar cell, dye adsorption is improved and efficient electrolyte penetration is performed, thereby increasing the photoelectric conversion efficiency.
