Description

  The present invention relates to a solar cell module, a manufacturing method thereof, and a construction method of the solar cell module.

  Since solar energy is inexhaustible and clean, the degree of attention has been increasing year by year as fossil fuels are depleted and environmental problems have become more serious. Currently, solar power generation systems that generate power using solar energy are installed in various places such as roofs of ordinary houses and wall surfaces of high-rise buildings.

  In many of the solar cell modules distributed in the market, a plurality of photovoltaic elements 10 are arranged between a reinforcing member 11 and a weather-resistant film 12 and sealed with a sealing material 13 as shown in FIG. It has been configured. In order to prevent the photovoltaic element from being damaged by an external stress, a material that is inferior in flexibility, such as a glass plate, is used for the reinforcing member. Therefore, the solar cell module does not have flexibility.

Recently, however, many ideas for flexible solar cell modules have been proposed. In JP-A-9-51118, JP-A-9-237911, and JP-A-11-135813, as shown in FIG. 2, a plurality of photovoltaic elements 20 are electrically connected by a wiring material 25 having flexibility, and a photovoltaic device is connected. An idea has been proposed in which a solar cell module is made flexible by forming an electrical connection body of a power element and sealing the electrical connection body with a front film 21, a back film 22, and a sealing material. As shown in FIG. 3, the solar cell module described in the idea is bent mainly in a region between photovoltaic elements in which no photovoltaic element exists.
JP-A-9-51118 Japanese Patent Laid-Open No. 9-237911 Japanese Patent Laid-Open No. 11-135813

  When the above-described solar cell module is bent into a roll shape, the area between the photovoltaic elements is more flexible than the area where the photovoltaic elements are present, and therefore the bending R is the smallest in this area. As a result, a large tensile or compressive stress is applied to the surface film and the back film in this portion. The surface film and back film described above are made of a material harder than the sealing material. If bending is applied with a small bending R, the material will be deformed beyond the elastic deformation region, and even if the bending is restored, A non-recoverable strain that does not return remains, and peeling occurs between the film and the sealing material, or in some cases, breakage occurs at that portion.

  In particular, in the region where the wiring material exists between the photovoltaic elements, the thickness of the sealing material is thinner than the region where there is no wiring material, and the adhesive force of the sealing material between the wiring material and the film is weakened. As a result, it was found that the film is particularly easily peeled off at the interface between the film and the sealing material on which a relatively large stress acts.

  When peeling occurs at the interface between the film and the sealing material, a space is formed at the interface. The space is hermetically sealed with a film and a sealing material, but moisture accumulates in the space because the film and the sealing material transmit water vapor. Since the moisture promotes corrosion of the wiring material provided between the photovoltaic elements, hydrolysis of the coating material, and the like, there is a possibility that the reliability of the solar cell module is remarkably lowered.

  The present invention has been devised in order to solve the above-described problems. When a flexible solar cell module is folded, the film is non-recovered in a region located immediately above and immediately below a wiring member. It is an object of the present invention to provide a solar cell module that prevents the occurrence of strain and prevents peeling at the interface with the sealing material.

  Means for solving the above problems will be described below.

  The solar cell module of the present invention includes at least a plurality of photovoltaic elements, a wiring material for electrically connecting the photovoltaic elements, a surface film disposed on the light receiving surface side of the photovoltaic elements, and a non-photovoltaic element. It has a back film placed on the light-receiving surface side, a sealing material for bonding each film and the photovoltaic element, and at least one film is provided with a cut in a region located immediately above and / or directly below the wiring material It is characterized by being. Moreover, in this invention, the extension part of the electrode provided in the photovoltaic element may be sufficient as the said wiring material.

  When a flexible solar cell module is bent, a large tensile or compressive stress acts on the area of the film discharged on the front and back sides of the photovoltaic element directly above or below the wiring material. Therefore, peeling at the interface between the film and the sealing material, generation of non-recovery strain, and film breakage have been problems. However, in the present invention, by providing a cut in a region located immediately above and / or directly below the wiring material of at least one film, the cut absorbs deformation due to compression or tension, and hence tensile stress acting on the film. Alternatively, the compressive stress can be greatly relieved, and as a result, the occurrence of the problem can be suppressed. Note that this portion is filled with a sealing material excellent in stretchability, and even when the small bending R as described above is applied, non-recoverable strain hardly occurs, and the covering material can be prevented from being broken.

  By providing a cut in the surface film in the region located directly above the wiring material, the solar cell module can be wound up in a roll shape with the surface film of the solar cell module facing outside. By providing a cut in the back film in the region located directly below the wiring material, the solar battery module can be wound up in a roll shape with the back film on the outside. That at least a part of the sealing material is continuously formed on the surface opposite to the sealing material of the front surface and / or the back film through the above-described incision, the adhesion between each film and the sealing material It is preferable because the strength can be improved and peeling at the interface between the film and the sealing material can be suppressed.

  When the solar cell module is rolled up in the direction of electrical connection of the photovoltaic element, a plurality of cuts are provided in a region of at least one film located immediately above and / or directly below the wiring material, the cut Is perpendicular to the electrical connection direction of the photovoltaic element, more effectively relieves the tensile or compressive stress acting on the film directly above and / or below the wiring material. Therefore it is desirable.

  In the present invention, the surface film is a fluoride polymer film, the back film is any one of a polyvinyl fluoride film, a nylon film, and a polyethylene terephthalate film, and the sealing material is an ethylene-vinyl acetate copolymer. Desirably, the resin is a coalesced resin, ethylene-methyl acrylate copolymer resin, ethylene-ethyl acrylate copolymer resin, ethylene-methacrylic acid copolymer resin, ionomer resin, or polyvinyl butyral resin.

  The method for manufacturing a solar cell module according to the present invention includes at least a step of electrically connecting a plurality of photovoltaic elements, a step of providing a cut in a region located directly above and / or directly below a wiring member of at least one film, The method includes a step of covering a plurality of connected photovoltaic elements with a film and a sealing material.

  It is desirable to use a single vacuum type laminating apparatus or a double vacuum type laminating apparatus in the step of covering the photovoltaic element.

  The solar cell module construction method of the present invention includes at least a step of folding and transporting the solar cell module, a step of expanding the folded solar cell module on the support, and a step of fixing the solar cell module to the support. It is characterized by including.

  When a cut is present in a region of the surface film located immediately above the wiring material, the method includes a step of covering the cut of the surface film with a light-transmitting film after the step of fixing the solar cell module to the support. In the case where a notch is present in a region of the back film located immediately below the wiring member and the solar cell module is fixed to the support using an adhesive, the notch of the back film member is covered with the adhesive. Thus, it is desirable to have the process of apply | coating an adhesive agent to a solar cell module or a support body.
