Abstract

A dye-sensitized solar cell of a polymer resin type is provided, which is excellent in sealability. A counter electrode substrate (1) provided with an electrically conductive transparent electrode layer (5) and a working electrode substrate (1') provided with an electrically conductive transparent electrode layer (5') are opposed to each other with the electrode layers (5, 5') facing inward. A space defined between the substrates (1, 1') is sealed with a seal member (4) disposed along peripheries of inner surfaces of the substrates (1, 1'). An electrolyte solution is filled in the sealed space. The substrates (1, 1') are each made of a polymer resin material. Inorganic layers (2, 2' , 3, 3') are provided between the substrates (1, 1') and the electrode layers (5, 5'). The seal member (4) is composed of a material obtained by curing a photopolymerizable composition essentially comprising a specific hydrogenated elastomer derivative. The inorganic layers (3,3') each have a portion coated with a (meth)acryloxyalkylsilane silage coupling agent in contact with the seal member (4).

Description

technical field

[0001] The present invention relates to a polymer resin (plastic film) substrate-type dye-sensitized solar cell in which a pair of electrode substrates face each other, are bonded and sealed, and an electrolyte solution is enclosed. A dye-sensitized solar cell with high sealing properties and excellent durability, and a sealing material therefor. Background technique

[0002] On titanium oxide (TiO) loaded with dye 2 A dye-sensitized solar cell obtained by enclosing a redox electrolyte solution between a transparent conductive substrate of a porous semiconductor film such as ) and an opposing electrode substrate is expected to be a next-generation inexpensive solar cell due to its high conversion efficiency of sunlight.

[0003] However, when a redox-based electrolyte solution such as iodine or lithium iodide is sealed in a polymer resin (plastic film) substrate, if the conventionally used ethylene-methacrylic acid copolymer ionomer resin is used as the seal...
