It is a schematic cross section which shows the structure of one Example of the dye-sensitized solar cell by the manufacturing method of this invention. It is a schematic cross section of the principal part which shows the structure of one Example of the dye-sensitized solar cell module by the manufacturing method of this invention.

  The method for producing a dye-sensitized solar cell of the present invention is formed of a laminate in which a transparent substrate, a transparent electrode layer, a power generation layer, a back electrode layer, and a back substrate are laminated in order from at least the light receiving surface side, and A dye formed by the power generation layer comprising an oxide semiconductor film obtained by firing fine oxide particles, a dye sensitizer carried on the oxide semiconductor film, and an electrolyte impregnated in the oxide semiconductor film In the method of manufacturing a sensitized solar cell, a step of applying a platinum or carbon paste in a pattern on a back substrate and drying to form a back electrode layer, and an oxide on the back electrode layer Applying a fine particle paste in a pattern, drying and baking to form an oxide semiconductor film, and impregnating the oxide semiconductor film by applying or dipping a solution of a dye sensitizer, followed by drying And a step of supporting a dye sensitizer, In which a dye sensitizer conductive layer to form a supported oxide semiconductor film and the back electrode layer and the back substrate laminate.

  Further, the method for producing the dye-sensitized solar cell module of the present invention is formed of a laminate in which a transparent substrate, a transparent electrode layer, a power generation layer, a back electrode layer, and a back substrate are sequentially laminated from at least the light receiving surface side, The power generation layer is formed of an oxide semiconductor film obtained by firing oxide fine particles, a dye sensitizer carried on the oxide semiconductor film, and an electrolyte solution impregnated in the oxide semiconductor film. In the method for producing a dye-sensitized solar cell module in which a plurality of dye-sensitized solar cells are arranged in a planar or curved shape and connected in series, the dye-sensitized solar cell A cell is manufactured by the above method for manufacturing a dye-sensitized solar cell.

  The power generation layer was impregnated in an oxide semiconductor film obtained by firing oxide fine particles having a particle diameter of 0.1 nm to 10 μm, a dye sensitizer supported on the oxide semiconductor film, and the oxide semiconductor film. It is possible to make a configuration in which at least 30% by weight of the oxide fine particles are fine particles having a particle diameter of 0.1 to 10 nm.

  The particle diameter of the oxide fine particles is preferably in the range of 0.1 nm to 10 μm, and the fine particles having a particle diameter of less than 0.1 nm are difficult to produce, and moreover, the particles tend to aggregate to form secondary particles. It is not preferable. In addition, fine particles having a particle diameter exceeding 10 μm are not preferable because the thickness of the oxide semiconductor film is increased more than necessary and the light transmittance is also decreased.

  By adopting such a configuration, the oxide fine particles forming the oxide semiconductor film of the power generation layer have a particle size in the range of 0.1 nm to 10 μm, and at least 30% by weight of the fine particles have a particle size of 0.00. Since it is a fine particle of 1 to 10 nm, the actual surface area inside the porous film to be formed is further increased, and at the same time the dye sensitizer is supported on the inner surface, so that light in a wide wavelength region is more effectively used. The photoelectric conversion efficiency of the dye-sensitized solar cell, that is, the power generation efficiency can be further increased. Further, since the oxide fine particles are less expensive than amorphous silicon or the like, the material cost can be reduced.

  A glass plate may be used for the back substrate, but a long heat-resistant film wound up in a roll shape can be used, whereby at least the back electrode layer thereon and the oxide semiconductor of the power generation layer The film and the dye sensitizer to be supported on the film can be formed by a roll-to-roll method using a wind-up / wind-up pattern coater such as a gravure direct coater, a rotary screen printer, or a dipping device. Therefore, productivity is remarkably improved, mass production is facilitated, and manufacturing cost can be reduced.

Oxide fine particles of the oxide semiconductor _{film, TiO 2, ZnO, SnO 2} , ITO, ZrO 2, SiO X, MgO, Al 2 O 3, CeO 2, Bi 2 O 3, Mn 3 O 4, Y 2 O ₃ , WO ₃ , Ta ₂ O ₅ , Nb ₂ O ₅ , La ₂ O ₃ fine particles, or a mixture of two or more fine particles.

  The oxide fine particles are suitable for forming an oxide semiconductor porous film as a power generation layer in terms of material, have high photoelectric conversion efficiency, and are relatively inexpensive in terms of cost. Therefore, by adopting such a configuration, in addition to the effects described above, a dye-sensitized solar cell with high photoelectric conversion efficiency and low cost can be more easily manufactured.

30% by weight or more of the oxide fine particles of the oxide semiconductor film can be TiO ₂ fine particles.

As the oxide fine particles used for the oxide semiconductor film of the dye-sensitized solar cell, it is relatively easy to produce fine particles of TiO ₂ fine particles having a particle diameter of 0.1 to 10 nm. It is particularly suitable in terms of high photoelectric conversion efficiency and low cost. Therefore, all of the oxide fine particles may be composed of TiO ₂ fine particles, but by forming 30% by weight or more of TiO ₂ fine particles, the formation of the highly porous film, high photoelectric conversion efficiency, and low cost are achieved. Such effects can be sufficiently obtained. Therefore, by adopting the configuration as described above, in addition to the above-described effects, a dye-sensitized solar cell with higher photoelectric conversion efficiency and lower cost can be manufactured.

  The said oxide semiconductor film can be set as the structure currently formed with the mixture which mixed the conductive binder with the oxide fine particle in the range of 1 to 30 weight%.

  By adopting such a configuration, in addition to the effects described above, when forming the oxide semiconductor film, the porous film can be formed at a lower heating temperature or a shorter heating time. In addition to improving productivity, when a heat-resistant flexible film is used as the back substrate, the level of heat resistance can be lowered, so that the range of film selection can be expanded and a cost reduction effect can be obtained.

The oxide semiconductor film may be surface-treated with a TiCl ₄ aqueous solution and / or an acetonitrile dispersion of t-butylpyridine up to the porous inner surface.

Surface treatment with the TiCl ₄ aqueous solution, a TiCl ₄ aqueous solution of less than 0.5M coated on the calcined oxide semiconductor film, after impregnation, can be carried out by a method of drying, this oxide semiconductor film The surface treatment with an acetonitrile dispersion of t-butylpyridine is less than 5% by volume of t-butylpyridine on the oxide semiconductor film after supporting the dye sensitizer. This can be carried out by applying and impregnating the acetonitrile dispersion liquid, followed by drying, whereby the backflow of electrons moved into the oxide semiconductor film is suppressed.

  Therefore, by applying such a surface treatment, the generated electrons can be used more efficiently in addition to the above-described effects, further improving the power generation efficiency of the dye-sensitized solar cell. Can be made.

  The dye sensitizer may be a ruthenium complex.

  As the dye sensitizer, an organic dye or a metal complex dye can be used. Examples of the organic dye include acridine, azo, indigo, quinone, coumarin, merocyanine, and phenylxanthene dyes. Among the metal complex dyes, ruthenium dyes are preferable, and ruthenium bipyridine dyes and ruthenium terpyridine dyes which are ruthenium complexes are particularly preferable. For example, visible light (wavelength of about 400 to 800 nm) can hardly be absorbed with only an oxide semiconductor film, but by supporting a ruthenium complex, visible light can be significantly taken in and photoelectrically converted.

  Therefore, by adopting the configuration as described above, in addition to the effects described in the above-mentioned request, the wavelength range of light that can be photoelectrically converted by the ruthenium complex can be greatly expanded, so that of the dye-sensitized solar cell Photoelectric conversion efficiency can be further improved.

  The electrolyte solution may be an iodine electrolyte solution, a gel electrolyte, or a solid electrolyte.

  As the electrolyte solution of the dye-sensitized solar cell of the present invention, an iodine electrolyte solution can be used effectively, but a gel electrolyte and a solid electrolyte can also be used. Gel electrolytes are roughly classified into physical gels and chemical gels, and the physical gels are gelled near room temperature due to physical interaction, and examples thereof include polyacrylonitrile and polymethacrylate. The chemical gel is a gel formed by a chemical bond by a crosslinking reaction or the like, and examples thereof include acrylate ester-based and methacrylate ester-based gels. Moreover, polypyrrole and CuI are mentioned as a solid electrolyte. When using a gel electrolyte or solid electrolyte, impregnating a low-viscosity precursor into an oxide semiconductor film and causing a two-dimensional or three-dimensional crosslinking reaction by means of heating, ultraviolet irradiation, electron beam irradiation, etc. It can be gelled or solidified.

  By adopting such a configuration, in addition to the effects described above, when an iodine electrolyte solution is used, the oxidation-reduction reaction is rapidly performed and the photoelectric conversion efficiency is improved. Further, when a gel electrolyte or a solid electrolyte is used, the liquid does not leak, and thus safety and durability are improved.

However, a plastic sheet having an appropriate thickness can also be used. When using a glass plate, the thickness is suitably in the range of 0.5 to 5 mm, preferably about 1 to 3 mm. When a plastic sheet is used, an ethylene / tetrafluoroethylene copolymer sheet is suitable in terms of weather resistance, but a biaxially stretched polyethylene terephthalate sheet or the like can also be used. When using a plastic sheet, the thickness is not particularly limited, but about 50 to 300 μm is appropriate.

The transparent electrode layer 2 is preferably excellent in conductivity and light transmittance (transmittance of light having a wavelength in the range of ultraviolet light to visible light). For example, a thin film layer such as SnO ₂ , ITO, ZnO or the like is used. Among them, a fluorine-doped SnO ₂ or ITO thin film layer is particularly preferable because it is excellent in both conductivity and light transmittance. As a method for forming a thin film layer of SnO ₂ or ITO, various vapor deposition methods can be used, but it is particularly preferable to form by a sputtering method in terms of good productivity and excellent performance. The thickness of the SnO ₂ or ITO thin film layer is suitably about 300 to 1500 mm.

Since the electrolyte solution 3 constituting the power generation layer 8 and the oxide semiconductor film 4 on which the dye sensitizer is supported have been described in detail above, description thereof is omitted here. When the oxide semiconductor film 4 is formed, a highly porous film can be easily formed by including polyethylene glycol in the coating solution. The thickness of the oxide semiconductor film 4 is preferably about 10 μm. Although not shown in the figure, the oxide semiconductor film 4 is preferably subjected to a surface treatment with a TiCl ₄ aqueous solution and / or an acetonitrile dispersion of t-butylpyridine as described above.

The back electrode layer 5 can be formed on the back substrate 6 by applying, for example, a platinum paste or carbon paste in a pattern and drying. In the case of using a platinum paste, for example, an H ₂ PtCl ₆ paste can be used, which can be applied after adjusting to a suitable viscosity with an organic solvent such as isopropyl alcohol, ethyl acetate, and toluene.

  Although a glass plate can be used for the back substrate 6, as described above, a heat-resistant flexible film that can be rolled up in order to improve productivity and reduce costs. Is preferably used. Examples of the heat-resistant flexible film include a biaxially stretched polyethylene terephthalate film, a polyethersulfone (PES) film, a polyetheretherketone (PEEK) film, a polyetherimide (PEI) film, and a polyimide (PI) film. Is mentioned. These may use a single film, and can also be used as a composite film in which other heat-resistant materials are laminated. The thickness of such a heat-resistant flexible film is not particularly limited, but about 16 to 100 μm is appropriate.

In the dye-sensitized solar cell module 200 shown in FIG. 2, three dye-sensitized solar cells having the configuration shown in FIG. 1 are arranged side by side at a predetermined interval, and each cell is electrically conductive.

The peripheral edge of each is sealed with a non-conductive sealing material 10, and positive or negative electrode leads 11 are drawn from the cells on both sides.

  Therefore, the configuration of each cell itself is the same as that of the dye-sensitized solar cell 100 shown in FIG. 1, and from the light incident side, the transparent substrate 1, the transparent electrode layer 2, the electrolyte solution 3, the dye-sensitized solar cell. The oxide semiconductor film 4 on which the sensitizer is supported, the back electrode layer 5 and the back substrate 6 are sequentially laminated or arranged.

However, the number of cells to be arranged is arbitrary. Yes, it can be freely designed to obtain a desired voltage.
