Description
Technical field
The utility model is related to a kind of crystal silicon solar battery component.
Background technology
Generating electricity by way of merging two or more grid systems and run after a period of time, home and abroad station successively with the photovoltaic plant of domestic and international up-front investment
Quality problems occur on a large scale, many power stations have broken into the quality problem of snail line, PID decay etc., and the problem triggers
Highest attention to power station quality both at home and abroad.Problem main cause one be each photovoltaic cell cell piece sole mass caused by electricity
The conversion efficiency of pond piece is low, reliability and weatherability is poor, service life is short；Two be due to existing photovoltaic module by cell piece
The EVA adhesive film for the solar cell array group front and back covering that connection in series-parallel is formed is the EVA adhesive film of individual layer single performance, its
It can not reach that reflection and translucent effect are all required well, and some producers have used the EVA adhesive film of poor quality, cause 70% light
Lie prostrate component and occur large-scale snail line problem, the power station also having has found that up to 60% decay for 1 year or so in operation.
Utility model content
The purpose of this utility model be exactly solve the above-mentioned problems in the prior art there is provided a kind of high conversion efficiency,
Reliability and good weatherability, the crystal silicon solar battery component of the high efficiency high reliability of service life length.
To complete above-mentioned purpose, technical solution of the present utility model is：A kind of crystalline silicon of high efficiency high reliability
Solar cell module, including formed by multiple cell piece connection in series-parallel solar cell array group, battery array group front
The reflective adhesive films of 3M of covering, the super EVA adhesive film covered on the reflective adhesive films of 3M layer, are covered on super EVA adhesive film layer
Preceding tempered float glassy layer, the battery array group back side cover white high reflection EVA adhesive film layer, in white high reflection EVA
The later half tempered float glassy layer that is covered on adhesive film, double glass dedicated hooks fixed on later half tempered float glassy layer and
The fixed split terminal box electrically connected with cell piece on later half tempered float glassy layer or battery component edge.
It is further preferred that the reflective adhesive films of described 3M include three layers：It is covered in the positive EVA adhesive film of battery array group
Layer, middle PET layer and outermost reflective membrane.When temperature reaches 70 DEG C, the EVA adhesive film layer of the reflective adhesive films of 3M is opened
Begin to melt and bond together with battery array group face bonding band, when sunlight is irradiated on reflective membrane, reflection occurs for sunlight simultaneously
Above preceding tempered float glass-reflected to cell piece, reflecting rate is further improved, so as to improve the power output of component.
It is further preferred that it is anti-to be added with the porous with core shell structure in described white high reflection EVA adhesive film layer
Optical medium.Further increase scattered light intensity, reach preferable diffusion effect.
Because the preceding tempered float glassy layer light transmittance that the utility model is used may be up to 94%, super EVA adhesive film layer is right
Below 360nm ultraviolet light transmission is obviously improved, and is added the ultraviolet light transmission to below 360nm, is worked as sun
When illumination is mapped on the reflective glued membranes of 3M, these sunlight occur reflection and by preceding tempered float glass-reflected to cell piece above,
Further improve reflecting rate；White high reflection EVA adhesive film layer and the reflecting effect of later half tempered float glassy layer below；Always
It, the mutual cooperation of these film layers and glass substantially increases the conversion efficiency of battery component, adds its reliability and weather-proof
Property, improve its service life；In the case of using identical solar cell array group, the utility model conversion efficiency ratio
The conversion efficiency of existing photovoltaic module improves more than 0.3%, and service life is brought up to more than 30 years.

Group 4, the reflective adhesive films 3 of 3M covered in the front of battery array group 4, the super EVA adhesive film layer covered on the reflective adhesive films 3 of 3M
2, the preceding tempered float glassy layer 1 covered on super EVA adhesive film layer 2, the white high reflection covered at the back side of battery array group 4
EVA adhesive film layer 5, white high reflection EVA adhesive film layer 5 on cover later half tempered float glassy layer 6, in later half tempered float glass
Fixed double glass dedicated hooks 7 and the fixed split terminal box electrically connected with cell piece on battery component edge on glass layer 6
8.Preferably, the reflective adhesive films 3 of described 3M include three layers：Be covered in battery array group positive EVA adhesive film layer, it is middle
PET layer and outermost reflective membrane.Preferably, being added with described white high reflection EVA adhesive film layer has nucleocapsid knot
The porous reflective medium of structure.
Certainly, the utility model also has other a variety of examples, in the case of without prejudice to the utility model spirit and essence,
Those skilled in the art can make corresponding change and deform according to the utility model, and these change and deformed accordingly
All should be in the utility model scope of the claims.
