AI Technical Summary

Problems solved by technology

However, depending on the electrolyte to be used, platinum may be dissolved, which may lead to deterioration of power generation characteristics
In addition, platinum is a rare resource and is relatively expensive; since a high-vacuum process or a high-temperature process is required in the process of forming the platinum layer, its production equipment needs to be large-scale

Embodiment 1-1）

[0172] [Preparation of Carbon Counter Electrode]

[0173]First, carbon black (manufactured by Mitsubishi Chemical Corporation, product name: #2600), vapor grown carbon fiber (VGCF) (manufactured by Showa Denko KK), and polyvinylidene fluoride (PVdF) (manufactured by Kureha Chemical Co., Ltd. Manufacture, Product Name: #7300) mixed thoroughly into a powder state. At this time, adjust the mixing ratio of each material so that the mass ratio (B / A) of carbon black (A) to vapor-grown carbon fiber (B) is 25 / 75, and polyvinylidene fluoride (N) is relatively The ratio ((N / M)×100) of the total amount (M) of all materials of the electrode was 2% by mass. In this case, all materials constituting the carbon counter electrode were carbon black, vapor-grown carbon fibers, and polyvinylidene fluoride. Subsequently, a carbon paste can be prepared by adding N-methylpyrrolidone to the mixed powder and stirring the resulting mixture with a paint shaker.

Embodiment 2-1 to 2-8）

[0190] The preparation of the dye-sensitized solar cell was the same as in Example 1-1, but the mass ratio (B / A) of carbon black (A) to vapor-grown carbon fiber (B) was changed to the value shown in Table 2.

[0191]

Embodiment 3-1 to 3-6）

[0193] The preparation of the dye-sensitized solar cell is the same as in Example 1-1, but the ratio of polyvinylidene fluoride (N) to the total amount (M) of all materials constituting the carbon counter electrode ((N / M)×100) The values ​​shown in Table 3 were changed, and the mass ratio (B / A) of carbon black (A) to vapor-grown carbon fibers (B) was fixed at 25 / 75.

Abstract

An electrode includes carbon black, a fibrous carbon material and an organic binder. The carbon black (A) and the fibrous carbon material (B) are in a mass ratio (B / A) within the range of from 10 / 90 to 50 / 50.

Description

technical field [0001] The present invention relates to electrodes, photoelectric conversion elements, electronic equipment and building structures. More particularly, the present invention relates to an electrode including a carbon material, a photoelectric conversion element using the electrode, an electronic device and a building structure using the photoelectric conversion element. Background technique [0002] Since a solar cell, which is a photoelectric conversion element that converts sunlight into electrical energy, uses sunlight as an energy source, the solar cell has little influence on the global environment and is expected to increase in popularity. Examples of solar cells mainly used in the past are crystalline silicon solar cells using single crystal silicon or polycrystalline silicon; and amorphous silicon solar cells. Simultaneously, The dye-sensitized solar cell proposed by et al. in 1991 has attracted wide attention because of its high photoelectric conv...
