Problems solved by technology

However, when such a structure is adopted, when the sealing member is cured, the uncured resin penetrates into the porous metal oxide layer, which not only causes a decrease in photoelectric conversion characteristics, but also causes the dye-carrying metal oxide layer to be damaged during long-term use. It will be cured or deteriorated, and / or its presence will become a factor that decomposes or deteriorates the electrolyte or pigment, etc., reducing the durability of the dye-sensitized solar cell

[0082] First, as a substrate, prepare SnO doped with fluorine 2 A transparent glass substrate (TCO: manufactured by AGC fabritech Co., Ltd., size: 25 mm in length x 25 mm in width) serving as a transparent conductive film was preliminarily cleaned. Next, a polyimide tape (Kapton Tape) was pasted in a frame shape on the transparent conductive film of the transparent glass substrate to form a mask, and silicon dioxide was formed into a film with a thickness of about 300 nm by sputtering. The polyimide tape is peeled off from the glass substrate to form a frame-shaped (outer dimension: vertical 10.0mm × horizontal 10.0mm, inner dimension: vertical 5.0mm × horizontal 5.0mm, frame width Δt: 2.5mm) short-circuit prevention layer in a pattern .

[0083] Next, commercially available zinc oxide particles (trade name: nano ZINC100, manufactured by Honjo Chemical Co., Ltd.) were added at 30 wt% to toluene, and dispersion treatment was performed for 30 minutes using a paint disperser to ...

Abstract

It is an object of the present invention to provide a dye-sensitized solar cell, etc. capable of preventing, even when a highly-conductive electrolyte is employed, a short circuit between a transparent conductive film of a working electrode and the electrolyte, and thereby enhancing reliability with improved photoelectric conversion characteristics and improved durability. A short circuit-prevention layer is patterned in a frame shape so as to surround the periphery of a dye-supported metal oxide layer on a region of a conductive surface where the dye-supported metal oxide layer is not formed. The short circuit-prevention layer is formed to be thinner than the dye-supported metal oxide layer, and the dye-supported metal oxide layer is formed so as to cover the conductive surface in the frame of the short circuit-prevention layer and to extend onto the short circuit-prevention layer. The dye-supported metal oxide layer and a sealing material are arranged apart from each other via the short circuit-prevention layer.

Description

technical field [0001] The present invention relates to a dye-sensitized solar cell, a method for manufacturing the same, and a method for manufacturing a working electrode for the dye-sensitized solar cell. Background technique [0002] In recent years, dye-sensitized solar cells have attracted attention because they can be produced at low cost and have high photoelectric conversion efficiency among organic solar cells. As the main constituent elements of the dye-sensitized solar cell, three points can be cited: a working electrode, an electrolyte, and a counter electrode. As a working electrode, an electrode in which a porous dye-carrying metal oxide layer is formed on a transparent conductive film formed on a substrate is generally used. The dye-supporting metal oxide layer is generally a layer in which a metal oxide semiconductor (metal oxide layer) supports (adsorbs) a sensitizing dye. Also, as a counter electrode, an electrode in which a platinum thin film is formed ...
