Embodiment 1

[0052] In this embodiment, the encapsulation front plate is composed of a composite film tightly covering the upper surface of the solar cell module, which is composed of multi-layer films. Wherein, 1 is an anti-sticking coating, the thickness is preferably 1-10um, more preferably 3-8um, more preferably 5um, which is distributed on the upper surface of the composite film of the front plate of the package, with anti-sticking, dustproof, self- Cleaning effect; 2 is frosted anti-aging coating, the thickness is preferably 1-10um, more preferably 3-8um, more preferably 5um, the specific composition of this layer preferably contains organic or inorganic frosted particles, for example, organic particles choose PMMA , PBMA, PDMS, the inorganic particles are SiO 2 、Al 2 o 3 , ZrO 2 , more preferably contains an anti-aging agent, and this layer has wear-resistant, scratch-resistant, and aging-resistant effects; 3 is the first film substrate layer, the thickness is preferably 50-200um...

Embodiment 2

[0062] In order to further improve the comprehensive performance of the packaging front panel, the composite film of the packaging front panel of the present invention can be improved in the following structure and process.

[0063] Preferably, on the basis of the composite film structure of the package front panel in Example 1, the lower surface of the water vapor barrier layer 5 is compounded with a layer of modified primer coating 6;

[0064] More preferably, the second film substrate layer 7 is compounded on the lower surface of the layer 6 .

[0065] The structural representation of the packaging front plate obtained in this embodiment is as follows: figure 2 shown.

[0066] Among them, the inventor of the present invention arranges the water vapor barrier layer on the middle layer of the composite film of the encapsulation front panel. On the one hand, it can avoid the water and gas generated by the battery assembly from damaging the water vapor barrier layer, and on t...

Abstract

The invention provides an packaging front panel and a preparation process thereof, wherein the packaging front panel is a composite film bonded on the upper surface of a solar cell module, and is characterized in that the composite film comprises an anti-adhesion coating, a frosted anti-aging layer, a first thin film base material layer, a first adhesive layer and a water vapor barrier layer fromtop to bottom. The packaging front panel of the invention can meet the requirements of lower water vapor transmission rate and lower service life (less than five years) of mobile energy sources, meanwhile, the flexible front panel has fingerprint-proof and scratch-resistant surface, simple and efficient packaging process, and low material and process cost. The package front board is lighter, thinner, softer than the traditional front board, lower material cost and simpler process.

Description

technical field [0001] The invention relates to a solar cell packaging assembly, and more particularly to a packaging front plate applied in the field of flexible mobile solar cells and a preparation process thereof. Background technique [0002] At present, in solar cell modules, the quality of encapsulation plays an important role in the service life of the cell. The closed structure of the front plate of the solar cell module is mainly used to isolate the air and water vapor from penetrating into the cell module, and to protect the solar cell. The packaging material generally uses adhesive film mainly made of PVB and EVA. Its function is to fix the battery sheet and isolate air and water vapor to ensure a long service life after the battery is packaged. However, PVB and EVA materials have deficiencies in the comprehensive performance of solar cell sealing, and the water blocking performance is not good enough. After a certain period of time, water vapor will enter the in...
