Abstract
The present invention relates to a kind of low-cost solar battery back-sheet; including PET base material; the side of described PET base material connects weathering layer by tack coat; upper surface in described weathering layer arranges polyester weathering protective layer; the other end in described PET base material connects weather-proof tack coat by tack coat, and described polyester weathering protective layer is mixed to form thin film by inorganic material, hydrolysising protection agent, UV absorbent and polyester slice.The solar cell backboard of the present invention under the conditions of 2000 hours ultraviolet irradiate and 75 DEG C of temperature 75% humidity aging after; back plate surface color is without significant change; the physical property of backboard with aging before the most unchanged, the present invention by use polyester weathering protective layer make processing be easier to, cost lower.
Description
Technical field
The present invention relates to solar components field, particularly relate to a kind of low-cost solar battery back-sheet.
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 effect that protection cell piece permeate from environmental factors, the solar energy of routine at present
Backboard is concentrated and is used fluoroplastics as weathering layer, and fluoroplastics, due to fluorine-containing, therefore have preferable weatherability, but due to fluoroplastics
Processing extremely difficult and have higher technical threshold, so supplier is few, it should and the price height restriction solar energy back of the body few for amount
Popularizing of plate.
Summary of the invention
The applicant, for above-mentioned existing issue, has carried out Improvement, it is provided that a kind of low-cost solar battery back-sheet,
It has manufacture processing simplicity, the advantage of low cost.
The technical solution adopted in the present invention is as follows:
A kind of low-cost solar battery back-sheet, including PET base material, the side of described PET base material is connected by tack coat
Weathering layer, the upper surface in described weathering layer arranges polyester weathering protective layer, and the other end in described PET base material passes through tack coat
Connecting weather-proof tack coat, described polyester weathering protective layer is cut by inorganic material, hydrolysising protection agent, UV absorbent and polyester
Sheet is mixed to form thin film.
Beneficial effects of the present invention is as follows:
The solar cell backboard of the present invention is under the conditions of 2000 hours ultraviolet irradiate and 75 DEG C of temperature 75% humidity
After aging, back plate surface color without significant change, the physical property of backboard with aging before the most unchanged, the present invention is by using
Polyester weathering protective layer makes processing be easier to, cost is lower.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Wherein: 1, weathering layer；2, tack coat；3, PET base material；4, weather-proof tack coat；5, polyester weathering protective layer.
Detailed description of the invention
The detailed description of the invention of the present invention is described below.
As it is shown in figure 1, a kind of low-cost solar battery back-sheet PET base material 3, tack coat 2 is passed through in the side of PET base material 3
Connecting weathering layer 1, the upper surface in weathering layer arranges polyester weathering protective layer 5, and the other end in PET base material 3 passes through tack coat 2
Connecting weather-proof tack coat 4, polyester weathering protective layer is by inorganic material, hydrolysising protection agent, UV absorbent and polyester slice
It is mixed to form thin film.The solar cell backboard of the present invention is under the conditions of 2000 hours ultraviolet irradiate and 75 DEG C of temperature 75% are wet
Degree aging after, back plate surface color without significant change, the physical property of backboard with aging before the most unchanged, the present invention passes through
Processing is easier, cost is lower to use polyester weathering protective layer to make.
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.
