SYSTHESIS OF PARTIALLY REDUCED AND MESOPOROUS STRUCTURED TUNGSTEN OXIDE AND APPLICATION FOR COUNTER ELECTRODE OF DYE SENSITIZED SOLAR CELL

摘要

The present invention relates to a dye-sensitized solar cell, and more particularly, to a tungsten oxide counter electrode having a uniform porous structure, a dye-sensitized solar cell using the same, and a method of manufacturing the dye-sensitized solar cell. The dye-sensitized solar cell according to the present invention comprises a photoelectrode; Metal oxides; dyes; An electrolyte, and a counter electrode, wherein the counter electrode is a partially reduced mesoporous tungsten oxide. The dye-sensitized solar cell according to the present invention uses a mesoporous tungsten suboxide (WO3-x) as a counter electrode of a dye-sensitized solar cell based on a T2 / T-electrolyte, And a 79% improvement in efficiency. In addition, the dye-sensitized solar cell according to the present invention exhibited excellent characteristics in the evaluation through cyclic voltammetry, electrhochemical impedance spectroscopy, and tafel polarization curve analysis.
