Problems solved by technology

Since thermoplastic elastomers must be laminated within 24 hours when exposed to air, otherwise they will fail, increasing the risk of material waste
[0005] The third is that the cells are easily damaged during transportation
During the lamination process of photovoltaic modules, photovoltaic modules need to be lifted and transported to the laminator, and problems such as cell fragmentation are likely to occur during transportation, which affects the production quality of photovoltaic modules

Embodiment 1

[0036] Embodiment 1 A production process of vacuum plastic-encapsulated photovoltaic modules

[0037] Such as Figure 1 to Figure 2 As shown, this embodiment includes the following steps:

[0038] S1. Stacking to form photovoltaic modules

[0039] The front-side encapsulation material 1 , the heat-treated thermoplastic elastomer 2 , the battery string 3 , the heat-treated thermoplastic elastomer 2 , and the back-side encapsulation material 4 are stacked sequentially from top to bottom to form a photovoltaic module.

[0040] Wherein, the front encapsulation material 1 can be tempered glass, the back encapsulation material 4 can be a back plate, and the front encapsulation material 1 and the back encapsulation material 4 can both be tempered glass. Thermoplastic elastomers are commonly used packaging materials for photovoltaic modules, such as EVA, POE, PVB and other materials. The heat-treated thermoplastic elastomer 2 refers to heating the thermoplastic elastomer to 140-150...

Embodiment 2～6

[0052] Embodiments 2-6 A production process of vacuum plastic-encapsulated photovoltaic modules

[0053] The difference between Embodiment 2 to Embodiment 6 and Embodiment 1 is only that the parameters in the steps are different, as shown in the following table for specific reference:

Abstract

The invention discloses a vacuum plastic package photovoltaic module production process. The production process comprises the following steps: S1, laminating to form a photovoltaic module: sequentially laminating a front packaging material, a thermoplastic elastomer subjected to heat treatment, a battery string, a thermoplastic elastomer subjected to heat treatment and a back packaging material from top to bottom to form the photovoltaic module; S2, forming a closed space: wrapping the side surface of the photovoltaic module with a side surface packaging material to form the closed space in the photovoltaic module; and S3, vacuumizing: vacuumizing the interior of the photovoltaic module through an air exhaust piece on the front packaging material or the back packaging material. The photovoltaic module is convenient to disassemble and recycle, the production efficiency is improved, and the energy consumption is reduced. The method is suitable for photovoltaic module production.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic modules, in particular to a production process of vacuum plastic-sealed photovoltaic modules. Background technique [0002] At present, in the production process of photovoltaic modules, the production process of stacking, lamination, and framing is generally adopted, that is, the backsheet, thermoplastic elastomer (such as EVA, POE, PVB, etc.), battery strings are stacked in sequence. , thermoplastic elastomer, glass, and then use a laminator to heat the thermoplastic elastomer to make it melt and then solidify, so that it can wrap the internal cell ribbon and paste it to the backplane and glass to achieve the sealing effect, and During the transportation of the components, it can offset the impact of deformation on the cells, and protect and buffer the cells. Then, the junction box and frame are placed on the laminated photovoltaic module to complete the installation process of the p...
