Description
Technical field
This utility model belongs to solar photovoltaic battery component technical field, is specifically related to a kind of high reflection-type solar energy back of the body
Plate.
Background technology
In view of the scarcity increasingly of non-renewable natural resources such as oil, coal, natural gas and ocean ice, again in view of the mankind
To the economy consciousness of natural resources and being obviously enhanced of protective awareness, to inexhaustible and have the feature of environmental protection and
The utilization of cheapness resource such as wind energy and solar energy is paid attention to increasingly, solar energy ground in the mankind's sustainable use energy strategy
Position shows day by day.Solaode is a kind of by photovoltaic effect, directly utilizes solar energy and is converted into electric energy
Device.The solaode of existing routine mainly utilize wave-length coverage 400～1100nm sunray carry out opto-electronic conversion,
But, general backboard reflectance is the most relatively low, a part of sunray can be made to cause light losing through backboard, thus reduce too
The photoelectric transformation efficiency of sun energy battery.There is the actual number of solar module producer it was demonstrated that backboard reflectance often promotes
The assembly generated output of 8%, 250W can improve 1～2W.As can be seen here, solar cell backboard is improved in wave-length coverage 400
～the sunray reflectance of 1100nm, it is one of important channel improving solar cell working efficiency.In the market
Solar energy backboard mainly has the structures such as TPT, TPE, and reflectance is relatively low, is difficult to more than 90%, and there will be after permanent use
The phenomenon that xanthochromia is aging, thus affect cell piece generating efficiency and assembly service life.
In view of above-mentioned prior art, it is necessary to the structure of existing solar energy backboard is improved.To this end, the applicant
Having made useful design, technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model is to provide a kind of high reflection-type solar energy backboard, has higher reflectance, can show
Write the work efficiency improving solaode, there is weatherability, resistance to ag(e)ing and the insulating properties of excellence, stain resistance simultaneously
By force, water vapor transmittance is little.
The purpose of this utility model is such to reach, a kind of high reflection-type solar energy backboard, it is characterised in that: include
Basic unit, weathering layer and internal layer, described basic unit is combined with weathering layer towards a side surface of weathering layer by the first tack coat
Being integrated, and basic unit is combined as a whole by the second tack coat and internal layer towards a side surface of internal layer, described basic unit is high
Reflectance mylar, described weathering layer and internal layer be high reflectance fluorinated copolymer layer, the first described tack coat and
Second tack coat is the adhesive layer with high reflectance.
In a specific embodiment of the present utility model, described high reflectance mylar is poly terephthalic acid
Any one in glycol ester thin film, polybutylene terephthalate thin film or PEN thin film.
In another specific embodiment of the present utility model, described high reflectance fluorinated copolymer layer is for containing anti-
Penetrate the politef of filler and/or polyvinylidene fluoride and/or copolymer layer that polyvinyl fluoride is made.
In another specific embodiment of the present utility model, described reflection filler be different-grain diameter titanium dioxide with
Common fillers or the combination of functional filler.
In another specific embodiment of the present utility model, described common fillers is calcium carbonate, Kaolin, Talcum
Powder or barium sulfate, described functional filler is hollow glass micropearl or solid ceramic microbeads.
This utility model is combined weathering layer and internal layer respectively on two surfaces of basic unit and constitutes multi-layer compound structure, institute
The multi-layer compound structure stated has good weatherability, resistance to ag(e)ing and insulating properties, and stain resistance is strong, water vapor transmittance
Little, service life was up to more than 25 years；Further, since use high reflectance mylar as basic unit, high reflectance is used to contain
Fluo-copolymer layer is as weathering layer and internal layer, and the adhesive layer of employing high reflectance is as first, second tack coat, thus has
Higher reflectance, is remarkably improved the work efficiency of solaode.
