Problems solved by technology

Therefore, the above-mentioned conventional method has cumbersome manufacturing steps, narrow range of manufacturing conditions (process tolerance, process tolerance), poor productivity and economical efficiency, and further has the problem of large variation in the performance of the obtained photoelectric conversion element.
[0012] In addition, in the above-mentioned conventional method, it is also desirable to use a low-viscosity (liquid) electrolyte composition, but in this case, there is a risk of liquid leakage during manufacture or when the battery is damaged, as with a solution-based electrolyte. , and it is difficult to obtain a photoelectric conversion element with sufficient safety and durability simply and at low cost

Embodiment 1

[0083] First, prepare a transparent glass substrate (manufactured by Asahi Glass Fabritec Co., Ltd.) with fluorine-doped SnO as a transparent conductive film, and screen-print a commercially available titanium oxide paste (particle size 18 nm), heated at 60°C for 10 minutes to dry the paste, and then fired at 450°C for 30 minutes to produce a titanium oxide film with a thickness of about 3 µm. Subsequently, adjust the ethanol solution of N719 pigment (pigment concentration: 3×10 -4 M) As a dye-adsorbing solution, the above-mentioned titanium oxide thin film was immersed in the dye-adsorbing solution at room temperature for 8 hours to perform a dye-adsorbing treatment, and then washed with ethanol and vacuum-dried to prepare a dye-loaded metal oxide layer , thus obtaining the working electrode.

[0084] Subsequently, commercially available carbon black (N 2 The specific surface area is 315m 2 / g), the electrolyte (pseudo-solid electrolyte) was prepared by kneading. The cont...

Embodiment 2

[0088] Except for using a glass fiber screen (manufactured by Clever Co., Ltd., the number of meshes per 1 inch square is 16, the mesh size is about 1 mm, and the thickness is 230 μm) as the mesh-shaped support member, other uses are the same as in Example 1. The electrolyte sheet of Example 2 (thickness is about 240 μm) was produced, and, except for using the electrolyte sheet of Example 2, other methods were processed in the same way as in Example 1, and a total of 5 samples of Example 2 were obtained. Photoelectric conversion element.

Abstract

The invention provides a photoelectric conversion device that has excellent photoelectric conversion efficiency and enhanced reliability without wide variations in performance. A manufacturing method of a photoelectric conversion device that includes a working electrode having a dye-supported metal oxide layer, a counter electrode disposed so as to face the working electrode, and an electrolyte layer enclosed between the working electrode and the counter electrode, includes: a step of preparing an electrolyte sheet in which an electrolyte is retained by a reticulated support member; and a step of enclosing the electrolyte sheet between the working electrode and the counter electrode.

Description

technical field [0001] The present invention relates to a photoelectric conversion element and a manufacturing method thereof. Background technique [0002] In recent years, the resource depletion of fossil fuels and environmental issues represented by the reduction of carbon dioxide emissions have attracted great attention. As one of the promising solutions, solar power generation is attracting attention. As typical examples of solar cells, monocrystalline silicon-based solar cells and polycrystalline silicon-based solar cells are widely known, and these solar cells have already been put on the market. However, in this technical field, concerns about insufficient supply of silicon as a main raw material have increased in recent years, and the next-generation non-silicon-based solar cells (for example, CuInGaSe 2 (CIGS, etc.) [0003] Among non-silicon solar cells, a dye-sensitized solar cell disclosed by Gratzel et al. in 1991 has attracted attention as an organic solar ...
