Title:
DYE-SENSITIZED SOLAR CELL AND METHOD OF MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2013/146933
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a dye-sensitized solar cell capable of widely expanding the light-absorption wavelength range without using a metallic complex dye, and capable of yielding exceptional photoelectric conversion characteristics; as well as to provide a method for manufacturing this dye-sensitized solar cell. The present invention is a dye-sensitized solar cell in which a porous metallic-oxide layer comprising metallic oxide particles is laminated on a transparent electroconductive layer of a substrate on which a transparent electroconductive layer has been formed, the dye-sensitized solar cell having a photoelectrode in which a sensitizing dye is supported on the porous metallic-oxide layer, wherein the sensitizing dye contains a cyanine-based organic dye and an indoline-skeleton-containing dye, the cyanine-based organic dye and indoline-skeleton-containing dye are supported in a plurality of levels on the porous metallic-oxide layer, and the cyanine-based organic dye is present in a higher concentration on the surface of the metal oxide particles than the indoline-skeleton-containing dye.
