METAL OXIDE DISPERSION AND PHOTOACTIVE ELECTRODE FOR DYE-SENSITIZED SOLAR CELL, AND DYE-SENSITIZED SOLAR CELL

摘要

(1) A metal oxide dispersion for a dye-sensitized solar cell containing metal oxide fine particles, a binder comprising a polymer compound having an action to bond with those fine particles, and a solvent; (2) a method for manufacturing a photoactive electrode for a dye-sensitized solar cell wherein a sheetlike electrode comprising a transparent substrate and a transparent conductive layer is coated with a dispersion containing the binder and metal oxide fine particles; (3) a dye-sensitized solar cell photoactive electrode manufactured by this method and containing a metal oxide containing the binder and metal oxide fine particles; and (4) a dye-sensitized solar cell comprising the photoactive electrode. A porous metal oxide film is formed over a sheetlike electrode without sintering at a high temperature, and a flexible and low-cost dye-sensitized solar cell which comprises a resin material of high transparency, low cost, light weight, and a degree of freedom in shape as a sheetlike electrode is manufactured.
