Disclosed is a method for solidifying carbon dioxide into carbonate, in which carbon dioxide is stably converted into and solidified into carbonate (mineral facies) by using steel slag or natural mineral by extracting an alkali component by supplying an ammonium salt solvent as an extraction solvent to raw slag and injecting carbon dioxide into an extract solution supplied to a carbonation reactor to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate. Then after the above two step are performed at least one an acetic acid solvent is supplied as an extraction solvent to the raw slag so as to finally extract an alkali component; and carbon dioxide is injected into an extract solution to produce carbonate precipitate from the extract solution through the induction of a conversion reaction of the carbon dioxide into the carbonate precipitate.

Disclosed is a dye-sensitized solar cell. The dye-sensitized solar cell includes a working electrode and a counter electrode configured to join the working electrode. The working electrode includes a photo electrode having a plurality of photo electrode cells coated on a transparent conductive substrate and arranged in linear rows and a collector having a plurality of collector cells coated on the transparent conductive substrate and arranged along perimeters of the photo electrode and between the photo electrode cells and a collector bottom portion integrally interconnecting the collector cells. The collector cells have a same length or the collector cells arranged along the perimeters have a different length from the collector cells arranged between the photo electrode cells to increase an active area of the photo electrode.
