Embodiment 1

[0119] (Preparation of Titanium Dioxide Semiconductor Particle Suspension)

[0120] 56.8 g of tetraisopropyl ortho-titanate was added dropwise to 200 mL of ion-exchanged water with sufficient stirring. After the dropwise addition was terminated, the hydrolysis was completed by further stirring for 1 hour, thereby obtaining the target titanium hydroxide precipitate. things. The precipitate was filtered using filter paper, and washed sufficiently with ion-exchanged water.

[0121] This precipitate was added to ion-exchange water in which 5.8 g of tetramethylammonium hydroxide (TMAH) was dissolved, and ion-exchange water was further added so that the total amount of the sample became 160 g.

[0122] After the sample was heated to reflux at 140° C. for 4 hours, microcrystals were removed through a glass filter, thereby obtaining a white turbid translucent colloidal solution.

[0123] The obtained colloidal solution was transferred to a closed autoclave vessel and subjected to hy...

Embodiment 2

[0149] Coating TiO with an average particle size of 400 nm on the Pt layer by screen printing 2 A slurry for forming a contact prevention layer in which particles are used as a material. Thereafter, the paste coated on the Pt layer was fired at a temperature of 150° C. for 1 hour, thereby obtaining a counter electrode having a contact prevention layer having a film thickness of 6 μm on the Pt layer.

[0150] Other conditions are identical with embodiment 1.

Embodiment 3

[0152] Coating TiO with an average particle size of 100 nm on the Pt layer by screen printing 2 A slurry for forming a contact prevention layer in which particles are used as a material. Thereafter, the paste coated on the Pt layer was fired at a temperature of 520° C. for 1 hour, thereby obtaining a counter electrode having a contact prevention layer having a film thickness of 6 μm on the Pt layer.

[0153] Other conditions are identical with embodiment 1.

Abstract

An antipole (20) for a dye-sensitization solar cell, the antipole being provided with a conductive layer (21), and a contact-preventing layer (23) formed of an insulating substance, the contact-preventing layer being formed on one surface of the conductive layer (21).

Description

technical field [0001] The present invention relates to a counter electrode for a dye-sensitized solar cell, and more specifically, to a counter electrode for a dye-sensitized solar cell that is less prone to defects such as short circuits and effectively reflects incident light, and a counter electrode having the dye-sensitized solar cell. Dye-sensitized solar cells with counter electrodes. [0002] This application is based on Japanese Patent Application No. 2012-204696 filed in Japan on September 18, 2012, Japanese Patent Application No. 2013-012408 filed in Japan on January 25, 2013, and Japanese Patent Application No. 2013 on August 22, 2013 Japanese Patent Application No. 2013-172711 of the application claims priority, and the contents thereof are incorporated herein. Background technique [0003] Dye-sensitized solar cells were developed by Gretzel (Switzerland) ) and other developed batteries have the advantages of high photoelectric conversion efficiency and low ...
