Embodiment Construction

[0015] Below, refer to the attached Figure one The preferred embodiments of the present invention will be described below. However, the present invention is not limited to the following embodiments. For example, the constituent elements constituting these embodiments may be appropriately combined with each other.

[0016] Hereinafter, the present invention will be explained in detail based on the best mode.

[0017] The electrolyte composition of the present invention contains an ionic liquid having a dicyanamide anion as an anion.

[0018] The ionic liquid is not particularly limited as long as it has a dicyanamide anion as an anion, and a room temperature molten salt that becomes a liquid at room temperature can be used. The cation corresponding to the dicyanamide anion includes, for example, a cation containing a quaternary nitrogen atom.

[0019] Cations containing quaternary nitrogen atoms (hereinafter referred to as "quaternary nitrogen atom-containing cations") can be exemp...

Abstract

An electrolyte composition containing ionic liquid having dicyanamide anions as anions. Examples of cations of the ionic liquid, may include, for example, cations having quaternized nitrogen atom. This electrolyte composition may contain halogen-based oxidized / reduced pair. This electrolyte composition is used as an electrolyte of a photoelectric conversion element.

Description

[0001] This application claims priority to Japanese Patent Application No. 2003-315955 filed on September 8, 2003, and its content is quoted here. Technical field [0002] The present invention relates to an electrolyte composition and a photoelectric conversion element using the electrolyte composition. Background technique [0003] The dye-sensitized solar cell was developed by Graetzel and others in Switzerland. It has the advantages of high photoelectric conversion efficiency and low manufacturing cost. It has attracted attention as a new type of solar cell (for example, see Japanese Patent No. 2664194, Japan Japanese Patent Application Publication No. 2001-160427, Japanese Patent Application Publication No. 2001-230434, Japanese Patent Application Publication No. 2002-184478). [0004] The general composition of the dye-sensitized solar cell is as follows: a working electrode and a counter electrode arranged opposite to the working electrode are provided, an electrolyte conta...
