preparation example Construction

[0069] The steps of the method for preparing a thin film electrode of the present invention will be described below with reference to FIGS. 1 and 2 . First, if Figure 1a As shown, a substrate 10 is provided; then, as Figure 1b As shown, the transfer film 30 is placed on the substrate 10, wherein the transfer film 30 includes a paint layer 31 and an underlayer 32, and the paint layer 31 is interposed between the underlayer 32 and the substrate 10, in this way The paint layer 31 can be transferred on the substrate 10; finally, as Figure 1c As shown, the film electrode 40 can be formed by removing the underlayer 32 .

[0070] In addition, in the method of the present invention, if Figure 2a As shown, the conductive base material 20 may be formed on the base material 10 according to circumstances including the conductive layer 15 . Conductive layers suitable for use in the method of the present invention include, but are not limited to, those selected from the group consis...

Embodiment 1

[0079] Preparation of transfer film

[0080] Get 17.5 parts by weight of titanium dioxide (ST-21, manufactured by Ishihara Co., Ltd., Japan, with 100% solid content), 7.5 parts by weight of polyester resin (5016-TS, manufactured by Changxing Chemical Company, with 100% solid content) and 75 parts by weight of solvent N-octyl Based pyrrolidone (NOP), they are stirred and mixed uniformly at a high speed to prepare a coating composition with a solid content of about 25% by weight, wherein the average particle diameter of titanium dioxide is about 25 nanometers.

[0081] The above-mentioned coating composition was coated on a polyethylene terephthalate (PET) release film (model: A71, manufactured by Teijin DuPont Co., Ltd., film thickness 50 μm) with an RDS coating rod #7, and the coating thickness was The transfer printing film of the present invention can be obtained after drying at 130°C for 10 minutes, and the thickness of the coating layer after drying is 6 microns.

Abstract

The invention relates to a transfer membrane used for preparing an electrode comprising (a) a bottom substrate and (b) at least a coating layer, which is disposed on the bottom substrate, and comprises binder and fillers. The thickness of the coating layer is in a range from 2-40 micrometers. The invention also relates to a manufacturing method of the membrane electrode, which comprises (1) providing a base material; (2) disposing the transfer membrane on the base material, and arranging the coating layer between the bottom substrate and the base material; (3) transferring the coating layer on the base material; (4) removing the bottom substrate to form the membrane electrode. The invention also relates to the membrane electrode manufactured by using the above mentioned method.

Description

technical field [0001] The invention relates to a transfer printing film used for preparing electrodes; the invention also relates to a method for preparing a thin film electrode; the invention also relates to a thin film electrode prepared by the method. Background technique [0002] With the rapid development of science and technology and economy, the use of energy has also increased significantly. The stocks of the most used raw materials such as oil, natural gas, and coal are constantly decreasing, and the increased demand must rely on other emerging energy sources. Among them, because solar energy is less polluting, it is currently one of the most promising and important energy research topics. So far, many different types of solar cells have been developed, among which dye-sensitized solar cells (Dye-Sensitized Solar Cell; DSSC) are considered to have the most development potential because of their low price. [0003] Dye-sensitized solar cells were first developed in...
