Problems solved by technology

However, there is a general problem in the use of the above two flexible solar cell assemblies. After repeated use, the metal wires in the folded part of the battery assembly will be broken, causing the entire product to be scrapped. The design service life of the product is much shorter. Choosing different types of metal wires or metal wires with better folding resistance will delay the breakage of the folded part of the wire, but it has a very limited effect on increasing the service life of the product, and conventional solar cell modules use The encapsulation adhesive encapsulates the metal wires and the battery chip together. After the packaging is completed, the metal wires are completely fixed by the glue. When the solar cell product is folded, the metal wires will also be folded repeatedly. Since the metal wires have been e

Example Embodiment

[0029] Example one

[0030] see figure 1 The structure of the multi-dimensional foldable flexible solar cell module of this embodiment is sequentially laminated with a back sheet material 7, an adhesive film 5, a plurality of flexible solar cell chips placed at intervals, a shielding material 8, an adhesive film 5, and a front plate material 6. As a result, the flexible solar cell chips 1 are arranged in 3 rows and 2 rows, with gaps between adjacent battery chips, forming a folding area of ​​the battery assembly. The wires connected in series and parallel of the flexible solar cell chip 1 are welded to the electrode lead-out tape 4 of the battery chip, connect multiple flexible solar cell chips 1 in series and parallel, and hollow out the glue film 5 where the wires are laid in the folding area to form a placement wire 2 and the braid 3 is placed above and below the hollowed out of the glue film. The size of the braid 3 is larger than the hollowed out size of the glue film. The m...

Example Embodiment

[0037] Example two

[0038] The manufacturing method of the multi-dimensional folded flexible solar cell module is as follows:

[0039] First cut the front plate material 6, the back plate material 7, the adhesive film 5, the flexible solar cell chip 1, and the shielding material 8, as well as the connecting wires 2 and braids 3 of appropriate length specifications according to the design size, in order from bottom to top Laminated backplane material 7, the glue layer facing upwards, the glue film 5 on the glue layer, the glue film 5 should cover the entire backplane material 7, and the flexible solar cell chip 1 is placed on the glue film 5 according to the design size. When placing the battery chip, leave the distance of the folded part according to the design size to position the flexible solar battery chip 1.

[0040] Use wires 2 to connect the flexible solar cell chips 1 in series and parallel. The wires 2 are welded to the electrode lead-out tape 4, and the electrode lead-out ...

Example Embodiment

[0050] Example three

[0051] In this embodiment, on the basis of the first and second embodiments, a protective layer of the flexible solar cell chip is added. The flexible solar cell panel is composed of multiple flexible solar cell chips in series and parallel. The folding area of ​​the battery module is reserved between adjacent flexible solar cell chips. The adhesive film where the wires are laid in the folding area is hollowed out to form an inner groove for placing the wires . A protective layer is added on the light-receiving surface and / or the backlight surface of each battery chip. The protective layer of the light-receiving surface of the flexible solar cell core board is a transparent polymer material, which is a material with high tensile strength, good light transmission, high temperature resistance and ultraviolet resistance, such as polyethylene terephthalate (PET ), the film adopts photovoltaic film material, which can be cross-linked at high temperature and pr...

Abstract

The invention relates to a multi-dimensional folded flexible solar battery pack and a manufacturing method thereof and belongs to the field of a solar photovoltaic technology. The technical problems that an interior metal lead in a flexible solar battery pack is easy to break and the like are solved. According to the multi-dimensional folded flexible solar battery pack, flexible solar battery chips are packaged between a front plate and a rear plate through an adhesive film; multiple flexible solar battery chips are in parallel connection through a lead string, so as to form a flexible solar photovoltaic array; an area for folding a battery pack is reserved between adjacent flexible solar battery chips; and an inner slot for storing the lead is arranged in the area for folding. The folding life of the multi-dimensional folded flexible solar battery pack designed by the invention is long; the folding times can reach above 4000 times, without the breaking condition of the metal lead; and the service life of the battery pack is ensured.

Description

technical field [0001] The invention relates to a multi-dimensional foldable flexible solar cell assembly and a manufacturing method, in particular to a flexible solar cell assembly with a high folding life and a manufacturing method thereof, belonging to the field of solar photovoltaic technology. Background technique [0002] With the improvement and demand of people's quality of life, the demand for mobile power is also increasing, and solar mobile power has undoubtedly become the most green and most suitable for modern life. Requirements, while the solar mobile power supply of traditional glass-encapsulated components has become a problem to be solved due to its heavy weight and large volume. With the development of flexible solar cell technology, its lightness, softness, and portability have become more and more concerns for commercial applications. However, due to its low conversion efficiency, a large battery area is required for a high-power mobile power supply. How ...
