Problems solved by technology

[0004] However, since dye-sensitized solar cells are electrochemical cells, organic electrolytes or ionic liquids are used as electrolytes. When organic electrolytes are used, they may volatilize or dry up during long-term use, reducing power generation efficiency. Problems, In addition, when using ionic liquids, although volatilization and depletion during long-term use can be prevented, leakage will cause durability problems such as structural deterioration

[0181] Organizing layered hydrous oxides is carried out by a regeneration method utilizing the regenerative properties of layered hydrous oxides.

[0182] (Organized Layered Hydroxide 1)

[0183] A commercially available layered hydrous oxide 1 (Mg-Al-based layered hydrous oxide, trade name: DHT-6, manufactured by Kyowa Chemical Industry Co., Ltd.) was calcined at 500° C. for 12 hours to obtain a calcined Layered water oxides. Next, a 0.1 M aqueous solution of sodium stearate (manufactured by Kanto Chemical Co., Ltd.) was prepared using ion-exchanged water (decarbonated ion-exchanged water bubbled with nitrogen gas). 2 g of the obtained calcined layered hydrous oxide was poured into 1 L of the above aqueous sodium stearate solution, and stirred at room temperature for 24 hours. Then, filtration and washing were repeated three times, followed by drying and pulverization to prepare the organic layered hydrous oxide 1 .

Abstract

The purpose of the present invention is to provide an electrolyte for use in a photoelectric conversion element that enables a dye-sensitised solar cell having excellent stability to be obtained. In the present invention the electrolyte for use in a photoelectric conversion element contains an organochloride compound (A) having level 3 or level 4 cations, and an organic layered double hydroxide (B).

Description

technical field [0001] The present invention relates to an electrolyte for a photoelectric conversion element, a photoelectric conversion element and a dye-sensitized solar cell using the electrolyte. Background technique [0002] In recent years, environmental problems such as global warming due to the increase in carbon dioxide have become serious, and non-silicon solar cells have attracted attention as solar cells that have a small environmental load and can reduce manufacturing costs, and research has been conducted on them. research and develop. [0003] Among non-silicon-based solar cells, dye-sensitized solar cells developed by Gretzel et al. in Switzerland, among solar cells using organic materials, have the advantages of high photoelectric conversion efficiency and lower manufacturing costs than silicon-based solar cells. , has attracted attention as a new type of solar cell. [0004] However, since dye-sensitized solar cells are electrochemical cells, organic ele...
