Abstract
The present invention relates to a good weather resistance solar cell backboard. The backboard comprises a PET base material, one end of the PET base material is connected with a weather resistance layer through a bonding layer, the other side of the PET base material is connected with a structure enhancement layer through the bonding layer, and the outer side of the structure enhancement layer is bonded with a weather resistance bonding layer. The materials of the weather resistance layer of the solar cell backboard is a fluorine-containing weather resistance layer, is low in cost, good in environmental protection performance, better in mechanical property and bonding intensity than a traditional backboard and more stable in the structure of the backboard, and has excellent effect on support and protection of the whole solar energy; and moreover, the solar cell backboard is obviously better than the current backboard, and has high heat-resistant and ageing-resistant performances, long service life and high weather resistance.
Description
Technical field
The present invention relates to solar-energy photo-voltaic cell field, especially a kind of high-weatherability solar cell backboard.
Background technology
Solar energy, as a kind of environmental protection, the inexhaustible energy, replaces the optimal choosing of tradition thermal power generation beyond doubt
Select, owing to solaode needs to be chronically exposed to outdoor practicality, so the cell piece in photovoltaic module needs to be protected by, come
Prevent impact and the vertical view of the environmental factorss such as the steam in air, oxygen, ultraviolet.Solar energy backboard is whole solaode
One of accessory, act primarily as mechanical support and protection cell piece exempt from the effect of environmental factors infiltration, the most how to improve backboard
Weathering row be always the research emphasis of the sector.
Summary of the invention
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that a kind of high-weatherability solar battery back
Plate, it can improve the weatherability of solar cell backboard further and extend its service life.
The technical solution adopted in the present invention is as follows:
A kind of high-weatherability solar cell backboard, including PET base material, passes through tack coat in the side of described PET base material
Connecting weathering layer, the opposite side of described PET base material is also by tack coat attachment structure enhancement layer, outside described structure enhancement layer
The most bonding weather-proof tack coat in side.
Its further technical scheme is:
The thickness of described PET base material is 250～300 microns；
The thickness of described weathering layer is 10～50 microns；
The thickness of described structure enhancement layer is 100～300 microns, and the thickness of described tack coat is 2～35 microns；
Described weathering layer is fluorine-containing weathering layer；
The thickness of described weather-proof tack coat is 40～60 microns.
Beneficial effects of the present invention is as follows:
The weathering layer material of solar cell backboard of the present invention is fluorine-containing weathering layer, and it has a low cost, good environmental protection,
Its mechanical property, adhesion strength are also good than conventional backing plate, and back board structure is more stable, and whole solar energy is supported protective effect more
Adding prominent, the solar cell backboard that the present invention provides is substantially better than existing backboard, and its wet-heat resisting ageing-resistant performance is high, the life-span
Long, weatherability is high.
Accompanying drawing explanation

A kind of high-weatherability solar cell backboard of the present invention includes
As it is shown in figure 1, a kind of high-weatherability solar cell backboard, including PET base material 3, logical in the side of PET base material 3
Crossing tack coat 2 and connect weathering layer 1, the opposite side of PET base material 3, also by tack coat 2 attachment structure enhancement layer 4, strengthens in structure
The most bonding weather-proof tack coat 5 in outside of layer.The thickness of PET base material 3 is 250～300 microns.The thickness of weathering layer 1 is 10～50
Micron.The thickness of structure enhancement layer 4 is 100～300 microns, and the thickness of tack coat is 2～35 microns.Weathering layer 1 is fluorine-containing resistance to
Wait layer.The thickness of weather-proof tack coat 5 is 40～60 microns.
The weathering layer material of solar cell backboard of the present invention is fluorine-containing weathering layer, and it has a low cost, good environmental protection,
Its mechanical property, adhesion strength are also good than conventional backing plate, and back board structure is more stable, and whole solar energy is supported protective effect more
Adding prominent, the solar cell backboard that the present invention provides is substantially better than existing backboard, and its wet-heat resisting ageing-resistant performance is high, the life-span
Long, weatherability is high.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, in the case of the basic structure of the present invention, the present invention can make any type of amendment.
