Embodiment

[0189] Hereinafter, the present invention will be more specifically described through synthesis examples and examples, but the present invention is not limited to the following examples. In addition, the number-average molecular weight and molecular weight distribution (Mw / Mn) measured below, using the GPC chromatograph "HLC-8020" (1 TSKgel α-M, 1 TSKgel α-2500) manufactured by Tosoh Co., Ltd., And under the analytical conditions of flow rate: 1.0 ml / min, stripping solvent: N,N-dimethylformamide, column temperature: 35° C., it is determined by gel permeation chromatography (GPC) method.

[0190] Copolymer Manufacture

Synthetic example 1

[0192] Into a flask having a cooling tube and a stirrer, 5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by mass of diethylene glycol ethyl methyl ether were added. Continue to add 40 parts by mass of glycidyl methacrylate, 18 parts by mass of styrene, 20 parts by mass of methacrylic acid and 22 parts by mass of N-cyclohexylmaleimide, and start to slowly stir after nitrogen replacement. The temperature of the solution was raised to 70° C., and the temperature was maintained for 5 hours to obtain a polymer solution containing a copolymer (A-1). The solid content concentration of the obtained polymer solution was 33.1% by mass. The number average molecular weight of the obtained copolymer was 7,000, and the molecular weight distribution (Mw / Mn) was 2.

Synthetic example 2

[0194] In a flask having a cooling tube and a stirrer, 5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 200 parts by mass of propylene glycol monomethyl ether acetate were added. Continue to add 40 parts by mass of 3-(methacryloxyethyl) oxetane, 10 parts by mass of styrene, 30 parts by mass of methacrylic acid and 20 parts by mass of N-cyclohexylmaleimide, and After nitrogen replacement, slow stirring was started. The temperature of the solution was raised to 70° C., and the temperature was maintained for 5 hours to obtain a polymer solution containing a copolymer (A-2). The solid content concentration of the obtained polymer solution was 33.1% by mass. The number average molecular weight of the obtained copolymer was 7,300, and the molecular weight distribution (Mw / Mn) was 2.

Abstract

The invention provides a resin composition capable of accurately coating a base plate with metal layout height difference and meanwhile forming a screen film capable of keeping high photoelectric conversion efficiency and having excellent corrosion stability. Furthermore, the invention provides the resin composition for forming the screen film at low cost only using the relative simple steps suchas the coating step and the heating step and an electrode for a dye sensitization solar battery with the screen film with corrosion stability with excellent photoelectric conversion efficiency. The electrode for the dye sensitization solar battery comprises the screen film formed by the resin composition, characterized in that: the resin composition comprises [A] having copolymer with at least one reactivity function base selected from the groups composed of a carboxyl group, an epoxy group and (methyl) acryl group.

Description

technical field [0001] The present invention relates to an electrode for a dye-sensitized solar cell, a resin composition for forming a shielding film of an electrode for a dye-sensitized solar cell, a shielding film and a method for forming the same, and a dye-sensitized solar cell having the shielding film. Background technique [0002] The dye-sensitized solar cell is a material developed by Glatzler et al. in Switzerland. Because it has advantages such as high photoelectric conversion efficiency and low manufacturing cost, it has attracted attention as a new type of solar cell (for example, see Japan JP-A-1-220380; Michael Graetzel et al., Nature (UK), 1991, No. 353, p.737). A dye-sensitized solar cell includes a working electrode on a transparent electrode substrate having an oxide semiconductor porous film formed of oxide semiconductor particles and loaded with a photosensitizing dye, a counter electrode opposite to the working electrode, and Electrolyte layer (charge...
