DYE-SENSITIZED SOLAR CELL AND METHOD OF MANUFACTURING SAME

摘要

The object of the invention is to provide a dye-sensitized solar cell and a method for making the same that allow for greatly broadening the light absorption wavelength range without using a metal complex dye, thereby achieving excellent photovoltaic characteristics. The dye-sensitized solar cell of the invention includes a photoelectrode having a substrate, a transparent conductive layer on the substrate, and a metal oxide porous layer containing metal oxide particles on the transparent conductive layer. The metal oxide porous layer has sensitizing dyes adsorbed thereon. The sensitizing dyes includes an organic cyanine dye and an indoline dye having an indoline structure. The organic cyanine dye and the indoline dye are supported by the metal oxide porous layer in a plurality of levels such that the organic cyanine dye is present in a higher concentration than the indoline dye on the surface of the metal oxide particles.
