Problems solved by technology

However, in fact, sufficient redox function cannot be obtained only by the ionic liquid matrix, and it is necessary to introduce iodine molecules. In this case, the viscosity of the electrolyte becomes high, and sufficient ion diffusion ability cannot be obtained.
In addition, these methods use liquid substances in essence, so that the problem about sealing cannot be solved in essence
Therefore, although the following methods have been proposed, that is, a method of forming a gel by mixing a gelling agent or the like in an electrolytic solution; The form of the substance is polyvinylidene fluoride or macromolecular materials such as polyethylene glycol, polyvinyl alcohol, and polyvinylpyrrolidone) and a method of quasi-solidification, but in this case, the ion diffusion ability become worse, so there are problems of lower conversion efficiency and worse battery life

preparation example Construction

[0147] In the production of the π-conjugated polymer (β), for example, first, if necessary, an electrolytic matrix solvent such as ion-exchanged water is acidified, and an emulsifier such as p-toluenesulfonic acid is added thereto. Then, monomers (I) to (III) are added thereto, and an oxidizing agent is added thereto to be oxidatively polymerized.

[0148] In the above reaction, examples of the acidic component used to make the electrolytic matrix solvent acidic include hydrochloric acid, sulfuric acid, perchloric acid, periodic acid, iron(III) chloride, and iron(III) sulfate. What is necessary is just to use about 0.5-4.0 mol of acidic components with respect to 1 mol of total amounts of the monomers (I)-(III) used about the quantity of an acidic component.

[0149] In addition, as the oxidizing agent used for the reaction, although it needs to be adjusted appropriately according to the redox potential of the aromatic compound (monomer) forming the π-conjugated polymer (β), e...

Abstract

[Solution to problem] The composition for a solid electrolyte of the present invention is characterized in that the composition comprises a polymer compound (A) and a charge transfer material and the polymer compound (A) is obtained by polymerizing a monomer (a) comprising a monomer (a-2) having chelating ability. The charge transfer material is preferably a carbonmaterial and / or a n-conjugatedpolymer (²). [Effects] When a polymer electrolyte layer of a dye-sensitized solar cell is formed from the composition for a solid electrolyte of the present invention, efficient charge transfer and sufficient charge life can be reconciled with each other.

Description

technical field [0001] The present invention relates to a composition for solid electrolyte and a solar cell using the composition. Background technique [0002] The role of the electrolyte layer in the dye-sensitized solar cell is more important, and the I - / I 3 - redox ability. Therefore, when aiming at a high-efficiency dye-sensitized solar cell, in order to fully exhibit the redox efficiency of iodine, a solvent with a high degree of ion dissociation is used for the electrolyte layer, and conditions that allow iodine ions to diffuse at a sufficient rate are required. However, when the use as a solar cell is considered, when the electrolyte layer is made into a liquid, strict sealing is required to prevent liquid leakage, gas diffusion, and the like. Furthermore, in order for iodine redox to function, it is also necessary to introduce iodine anion and iodine molecule, and these may cause problems of corrosion and deterioration of materials. [0003] As a solution to...
