Problems solved by technology

[0013] In order to prevent moisture absorption of solar cells, the surface protection film is generally covered with an adhesive resin, but after durability tests such as moisture resistance tests and weather resistance tests, the adhesion of the interlayer interface has decreased. Moisture absorption in this part reduces the power generation output

Embodiment 1

[0135] Arrange 10 solar cell units with a width of 260 mm and a length of 80 mm in series, and then assemble them with a collector connector to form a flexible solar cell module. The adhesive resin described above was laminated on the central part of a flexible waterproof supporting film material with a width of 1000 mm and a length of 1500 mm, and bonded and integrated.

[0136] As the adhesive resin, an acrylic resin cross-linked by a coupling agent compound (such as an epoxy-based silane coupling agent) and an epoxy resin (such as a urethane-modified epoxy resin) is used.

[0137] In addition, as the fiber fabric for the base fabric of the flexible waterproof supporting membrane material, a base fabric plain weave (mass per unit area: 160 g / m 2 , Density: 40 warps / 25.4mm, 50 wefts / 25.4mm). Furthermore, the following flexible waterproof resin film was pasted on the base fabric of the above-mentioned flexible waterproof supporting film material.

[0138] As a flexible water...

Embodiment 2

[0160] A flexible film-shaped solar cell multilayer was produced in the same manner as in Example 1 and used for testing. However, the flexible surface protective film layer was formed with an ethylene-tetrafluoroethylene copolymer film (50 µm in thickness) having an area of ​​150% with respect to the area of ​​the solar cell layer.

[0161] The test results are shown in Table 1.

Embodiment 3

[0163] A flexible film-shaped solar cell multilayer was produced in the same manner as in Example 1 and used for testing. However, the flexible surface protection film layer was formed with a polyvinyl fluoride film (thickness: 50 μm) having an area of ​​150% with respect to the area of ​​the solar cell layer.

[0164] The test results are shown in Table 1.

Abstract

The invention provides a flexibility water proof membrane solar cell compound layer body capable of preventing a conductive section moisture absorption and power output from reducing, wherein a solar cell layer (1) is jointed on a flexibility water proof support membrane material (5), a flexibility adhesive resin layer (9) and a flexibility surface protective membrane layer (10) are covered on the solar cell layer in turn, and further extend outward, thereby jointing on the support membrane material (5). The solar cell layer is sealed. An anode and a cathode conductive sections in the solar cell layer are covered directly by a conductive section damp course or indirectly by the resin layer (9), and a crosslinking resin layer (6) formed between the resin layer (9) and the membrane layer (10) according to demands.

Description

technical field [0001] The present invention relates to a flexible film-shaped solar battery composite layer. In more detail, the present invention relates to a flexible film-shaped solar cell multilayer body that includes a flexible solar cell and is excellent in moisture resistance and water resistance. The flexible film-shaped solar cell laminate of the present invention is used as a component of large tent structures, tent warehouses, sunshade tents, house tents, agricultural houses, truck covers, shutters, etc. that need to be rolled up or bent for transportation or storage. is useful. Background technique [0002] The energy source of solar cells is the sun, so it is inexhaustible, and unlike fossil energy, it is not exhausted. Therefore, solar cells are expected as clean energy that has zero load on the environment and contributes the most to preventing global warming. In addition, amorphous silicon solar cells have the advantages of being thin and lightweight, low ...
