Description
Technical field
The present invention relates to a kind of composite material more particularly to a kind of composite materials for photovoltaic module synergy and its should
With.
Background technology
There is a kind of reflective composite material in the prior art, stick between the silica-based solar surrounding of photovoltaic and string piece
White space region, can be good at improve solar components efficiency.Its principle is by reflected light by the diffusing reflection of light
Crystal silicon solar batteries on piece is irradiated to again by glass back, so as to achieve the effect that put forward effect.Passed through with upper type unrestrained anti-
It penetrates and understands the angle of total reflection that glass is not achieved in some light, glass loss is penetrated, so the illumination ratio using cell piece gap
It is relatively not high.
Invention content
The present invention mainly solves the deficiencies in the prior art, provides a kind of compact-sized, is entered using rational design illumination
Firing angle degree and reflection angle reach more than the angle of total reflection with making incident light maximum ratio, and the one kind being reflected on cell piece is used for
The composite material of photovoltaic module synergy and its application.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of composite material for photovoltaic module synergy, including reflective layer and insulating protective layer, the reflective layer includes UV

Section is shaggy tooth, and the end face of the shaggy tooth forms reflecting surface；
Insulating protective layer includes upper pet layer and lower pet layer, and the top of the lower pet layer is equipped with upper pet layer, and the UV is anti-
Photosphere is located between pet layer and lower pet layer, and the UV reflective layers are equipped with synergy component with insulation protection interlayer.
Preferably, the synergy component includes EVA layer, surface and the bottom surface of the upper pet layer are respectively equipped with EVA
Layer.
Preferably, the synergy component includes EVA layer and UV filled layers, the surface of the upper pet layer is equipped with EVA
Filled layer is equipped between the bottom surface of layer, the surface of the aluminium plating membrane and upper pet layer.
Preferably, the filled layer is UV filled layers or EVA filled layers.
Preferably, the thickness of the upper pet layer and lower pet layer is respectively 0.1mm.
A kind of application of composite material for photovoltaic module synergy：
After photovoltaic module battery strings pendulum string, the composite material of 5~7mm width is uniformly sticked into the back electrode string piece with component
Between about 1.5-4mm white space；Reflective surface and cell piece light-receiving surface are in the same direction, and composite material and cell piece gapless or gap are not
More than 0.3mm；
The part for being located at string piece white space to composite material with 110~150 DEG C of heating modules or hot wind after laying is heated,
It is made to be bonded with upper strata EVA to be held in position；Or sticked on the composite using laminator adhesive tape keep cell piece with it is compound
The positioning of material；
Extended meeting to this pad pasting heat and be sticked with automation equipment afterwards.
Preferably, when sticking 60 silicon based cells components（Wherein longitudinal direction string 10, direction battery；6 between transversal flaps
Piece battery）, pad pasting unit can be entered by assembly line after automatic laying battery strings equipment has laid battery strings.Pad pasting unit
Position where component is positioned, starts to stick reflective pad pasting after accurate.
It is relatively accurate in view of the beat needs of pipelining；The whole flow process time for sticking pad pasting needs to control
Between 30-40 seconds, this just needs 9 lateral silver spacing and the string spacing of longitudinal direction 5 to stick simultaneously；In the transverse direction of film sticking apparatus
9 storage devices and 9 automatic traction discharging equipments need to be placed；5 storage devices and 5 need to be placed in the longitudinal direction of film sticking apparatus
It is automatic to draw discharging equipment, ensure 9 lateral in the given time drawing mechanisms while move once to complete laterally to discharge to apply
If 5 longitudinal drawing mechanisms move primary completion longitudinal direction discharging laying simultaneously.
Wherein reflective layer makes depth with UV materials on the PET of 0.1mm thickness essentially according to the reflection angle of light and is
The prism angle that 0.01-0.02mm is suitble to, then reach by aluminizing on prism the orientation mirror-reflection of light.Due to this composite wood
Material the face of aluminizing need to stick with two panels silicon based cells back electrode both sides, if do not do insulation processing be likely to occur in subsequent use it is short
Transportation work style danger.
PET is good insulating materials.And the transparent PET light of 0.1mm thickness is not in the process thoroughly light loss substantially,
The protection of one layer of anti-ultraviolet ageing is done in the light-receiving surface of PET, is fully available for the protection of reflective membrane aluminium coat.Therefore it selects with transparent
PET is used as the insulating layer of aluminium coat.
Since aluminium coat prismatic reflection structure is there are small bumps, such as directly with PET and aluminium coat it is compound can cause it is recessed
The air of convex can not be extracted out, hide some dangers for photovoltaic silicon-based devices finished product.One kind is in transparent PET double-coated EVA or one side
Doing the mode of UV structures one side coating EVA can effectively solve the problems, such as that gas is discharged in reflective structure.It is set finally by compound
It is standby that reflective layer and insulating layer is compound, just obtain the composite material of this patent.
A kind of composite material and its application for photovoltaic module synergy provided by the invention further promotes product matter
Amount improves product stability energy.
