Problems solved by technology

[0003] In the above-mentioned production method of solar cell modules, there are the following defects: the coating time of butyl rubber strips is long, and one size of glass corresponds to a set of coating parameters, which is not flexible enough; the current glass size of 1616mm*984mm is standardized, and the design is limited
Reserve the position of the butyl rubber strip to reduce the battery laying area; the design of the butyl rubber strip is too narrow, which weakens the ability to isolate air and water vapor, resulting in shortened TV life
Packaging film, the incoming material needs to be cut, and during laying and moving before lamination, it is easy to produce wrinkles, offsets, etc., resulting in defective components after lamination

Embodiment 1

[0034] see figure 1 , the embodiment of the present invention provides a solar cell module packaging method, the packaging method includes the following steps:

[0035] S1, providing a substrate 5, a battery sheet group 3 and a front plate 1, the battery sheet group 3 including opposite first surfaces and second surfaces;

[0036] The material of the substrate 5 is glass, metal, semiconductor or organic plastic; the material of the front plate 1 is glass or transparent organic plastic. In this step, the substrate 5 and the front plate 1 need to be cleaned to avoid introducing impurities and affecting light transmittance.

[0037] In order to improve the ability of the edge of the finished module to resist water vapor or air erosion, in this embodiment, when arranging the battery pack 3 , a certain area is reserved at the edge, and the reserved area is filled with protective glue in subsequent steps. The width of the reserved area is related to the thickness of the battery sh...

Embodiment 2

[0052] This embodiment provides a method for packaging solar cell modules. The difference between this embodiment and Embodiment 1 is that in this embodiment, after the protective adhesive is arranged between the substrate 5 and the battery sheet group 3, in order to prevent the battery For the drift of the sheet group 3 , the present embodiment uses a mold or a fixture to limit the position of the battery sheet group 3 .

[0053] Likewise, this embodiment is not only applicable to the improvement of the encapsulation method of the first embodiment, but also applicable to the improvement of the encapsulation method of the second embodiment.

Embodiment 3

[0055] The difference between this embodiment and the above-mentioned embodiments is that in this embodiment, the stacked front plate 1, battery sheet group 3 and substrate 5 are fixed with a jig or a mold, and then the substrate 5 and the battery are sealed by potting. Sheet group 3, potting is performed between the front plate 1 and the cell sheet group 3; after the potting is completed, heating and lamination are carried out; similar to Example 1, in order to reduce packaging defects, it can be put into a sealed container and pumped. Vacuum treatment followed by heating and lamination.

Abstract

The invention discloses a solar cell module and a package method thereof, and mainly aims at the problems that areas of a substrate and a front plate are occupied by an existing package method and a battery piece group is small in laying range. The substrate, the battery piece group and the front plate are provided, wherein the battery piece group comprises a first surface and a second surface which are opposite to each other. The package method comprises the following steps of laminating the battery sheet group and the substrate, and arranging liquid-state protection glue between the first surface and the substrate, wherein the protection glue completely covers the first surface; laminating the front plate, the battery piece group and the substrate, and arranging the liquid-state protection glue between the second surface and the front plate, wherein the protection glue completely covers the second surface; and heating and laminating the substrate, the battery piece group, the front plate and the protection glue. By the package method, a butyl adhesive tape is not needed, the laying range of the battery piece group is expanded, moreover, a glue film is not needed to be cut duringprotection glue coating, the protection glue coating is free from the limitation of the specification of the glue film, and the production is relatively flexible.

Description

technical field [0001] The invention relates to a solar battery component and a packaging method thereof. Background technique [0002] Existing battery modules, taking the double-glass module structure as an example: include sequentially stacked backplane glass, encapsulant film, battery sheet, diode string, bus bars (+, -), encapsulant film and front glass. Wherein, butyl glue needs to be filled around the encapsulation film. [0003] In the above-mentioned production method of solar cell modules, there are the following defects: the coating time of butyl tape is long, and one size of glass corresponds to a set of coating parameters, which is not flexible enough; the current glass size of 1616mm*984mm is standardized, and the design is limited. Reserve the position of the butyl rubber strip to reduce the battery laying area; the design of the butyl rubber strip is too narrow, which weakens the ability to isolate air and water vapor, resulting in shortened TV life. For pa...
