Embodiment 1-1

[0139] As a specific example of the photoelectric conversion element described in the above embodiment, a dye-sensitized solar cell was produced by the following procedure.

[0140] 【0063】

[0141] First, the working electrode 10 is fabricated. Initially, the F-SnO 2 One side of the conductive substrate 11 is electrolytically separated to an area of ​​1cm 2 The metal oxide semiconductor layer 12 containing zinc oxide is formed in a manner. When forming the metal oxide semiconductor layer 12, first, prepare a 40cm 3 , a counter electrode comprising a zinc plate, and a reference electrode comprising a silver / silver chloride electrode. As the electrolytic bath, use a concentration of eosin Y30μmol / dm 3 , Zinc chloride 5mmol / dm 3 , potassium chloride 0.09mol / dm 3 of aqueous solution. After bubbling the electrolytic bath with oxygen for 15 minutes, the temperature of the electrolytic bath was set to 70° C., and while bubbling, constant potential electrolysis at a potential ...

Embodiment 1-2～1-5

[0150] Mixed with the electrolytic solution so that the content of CB in the electrolyte-containing layer 30 reaches 10% by weight (Example 1-2), 30% by weight (Example 1-3), 40% by weight (Example 1-4) or 60% by weight (Example 1-5) was prepared, and the procedure similar to Example 1-1 was carried out except that.

[0151] 【0068】

Embodiment 2-1～2-3

[0172] Change the content (molar concentration) of TBAI in the electrolyte to 0.13mol / dm 3 (Example 2-1), more preferably 0.25mol / dm 3 (Example 2-2) or 0.75mol / dm 3 (Example 2-3) Except for this, the procedure similar to Example 1-4 was carried out.

Abstract

The present invention provides a photoelectric conversion device capable of improving durability without using particular material. The photoelectric conversion device includes a working electrode in which dye is carried by a metal oxide semiconductor layer and a facing electrode having a conductive layer, and a semi-solid electrolyte containing layer supported between the working electrode and the facing electrode. The electrolyte containing layer contains an electrolyte solution in which a solid electrolyte salt is dissolved in an organic solvent, and a particle. Thereby, liquid leakage or the like hardly occurs even under a high-temperature environment in comparison with the case where the electrolyte containing layer does not contain a particle.

Description

【Technical field】 [0001] 【0001】 [0002] The present invention relates to a photoelectric conversion element using a dye. 【Background technique】 [0003] 【0002】 [0004] Conventionally, dye-sensitized photoelectric conversion elements using a dye as a photosensitizer are known as photoelectric conversion elements such as solar cells that convert light energy such as sunlight into electrical energy. The dye-sensitized photoelectric conversion element can be expected to have high efficiency theoretically, and it is generally considered to be very cost-effective compared to a photoelectric conversion element using a silicon semiconductor that has been widely used. For this reason, they are attracting attention as next-generation photoelectric conversion elements, and are being developed toward practical use. [0005] 【0003】 [0006] This dye-sensitized photoelectric conversion element generates electricity by utilizing the property of a dye to absorb light and release elect...
