Abstract
The utility model relates to a solar battery backboard with a weather-resistant protection layer being made of polyester, which comprises a first adhering layer, a structural reinforced layer, a second adhering layer and a heat sealing layer, which are sequentially laminated together, and is characterized in that: the surface layer of the first adhering layer is provided with a polyester weather-resistant protection layer. The solar battery backboard has the advantages that: the polyester weather-resistant protection layer is adopted, so the material is easy to obtain, the solar battery backboard is easy to process, and the cost is low.
Description
Technical field
It is the solar cell backboard of weathering protective layer that the utility model relates to a kind of polyester film that adopts.
Background technology
Along with the development of low-carbon economy, national governments more and more pay attention to the utilization to solar energy, are used for substituting exhausted day by day petrochemical industry resource.The utilization of solar energy mainly is converted into electric energy through solar panel and supplies human the use.
Solar panel is the photoelectric cell that the luminous energy of the sun is converted into electric energy, and primary structure is top board/encapsulating material/solar cell circuit/encapsulating material/backboard.Wherein top board and encapsulating material have high light transmittance; Backboard light tight main play protection solar cell circuit and encapsulating material effect; Avoid destroying solar cell circuit and encapsulating material, the mechanical protection and the electrical insulation capability of solar cell also is provided simultaneously with steam and oxygen.
Because a large amount of uses of solar cell, each company concentrates and adopts fluoroplastics as weathering layer the many patents of solar cell backboard application.Fluoroplastics so have good weather, are fit to do the weathering layer of solar cell backboard owing to fluorine-containing very much.Difficulty has higher technical threshold but because fluoroplastics are processed very; So supplier is less; Mainly contain Dupont, French Acker agate, Japan AGC etc., the supply of fluoroplastics is lacked and the price height becomes the bottleneck that restriction solar cell large-scale popularization is used.
Summary of the invention
It is easy that the purpose of the utility model provides a kind of manufacturing processing, the solar cell backboard that cost is low.
In order to achieve the above object; The technical scheme of the utility model has provided the solar cell backboard that a kind of protective layer of anti-marquis is a polyester; Comprise first adhesive linkage, structure enhancement layer, second adhesive linkage and the hot sealing layer that stack gradually, it is characterized in that: be provided with resistant polyester marquis protective layer on the surface of first adhesive linkage.
Further, the thickness of said resistant polyester marquis protective layer is the 5-80 micron.
The thickness of said structure enhancement layer is the 20-500 micron.
The thickness of said hot sealing layer is the 20-200 micron.
The thickness of said first adhesive linkage and said second adhesive linkage is all the 1-20 micron.
The utility model has the advantages that: adopt resistant polyester marquis protective layer, material is easy to get, handling ease, cost are low.
Description of drawings
A kind of protective layer of anti-marquis that Fig. 1 provides for the utility model is the structural representation of the solar cell backboard of polyester.
Embodiment
For making the utility model more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
As shown in Figure 1; A kind of protective layer of anti-marquis that the utility model provides is that the solar cell backboard of polyester comprises first adhesive linkage 2, structure enhancement layer 3, second adhesive linkage 4 and the hot sealing layer 5 that stacks gradually, and is provided with resistant polyester marquis protective layer 1 on the surface of first adhesive linkage 2.
The thickness of resistant polyester marquis protective layer 1 is the 5-80 micron.The thickness of structure enhancement layer 3 is the 20-500 micron.The thickness of hot sealing layer 5 is the 20-200 micron.The thickness of first adhesive linkage 2 and said second adhesive linkage 4 is all the 1-20 micron.
The manufacture method of resistant polyester marquis protective layer 1 is with inorganic material, hydrolysising protection agent, ultra-violet absorber and after polyester slice mixes, and through the double screw extruder extruding pelletization, each component is fully mixed.Process the film of 50 micron thickness through casting sheet, biaxial tension, moulding.
The solar cell backboard of the utility model through under 2000 hours ultraviolet irradiation conditions with 85 ℃ of temperature 85% humidity aging after; The back plate surface color does not have significant change; The instructions for use of solar cell backboard is satisfied in the physical property of backboard and aging preceding basic not variation fully.
