The advantages that melting temperature is low, adhesive property is good, volume resistivity is high, at low cost.
It is also higher and higher for the functional requirement of photovoltaic encapsulation glue film with being constantly progressive for photovoltaic market, using high anti-
Back side encapsulating material of the injection film as photovoltaic module, can significantly improve component generated output, the solution that patent proposes at present
Scheme is mostly the problem of white glue film is primarily present filler overflow using white glue film, and being easy covering solar battery sheet causes
The decline of component power.
In addition, the barrier property for improving encapsulating material at present, which relies primarily on back veneer material, either uses other encapsulating materials,
The barrier property for directly improving EVA adhesive film has not yet to see all reports.
Utility model content
The purpose of this utility model be solve the problems, such as above-mentioned the deficiencies in the prior art and, propose a kind of solar energy
Battery component and its packaging adhesive film, packaging adhesive film reflecting properties with higher and the barrier property to steam improve component
Generating efficiency guarantees assembly life-span.
In order to achieve the above objectives, the technical solution adopted in the utility model are as follows:
A kind of packaging adhesive film of solar cell module, including base layer and reflection barrier layer, the reflection barrier layer is
The coating with a thickness of 8-500nm being formed in the base layer.
Preferably, the coating is one or more stacking formation in aluminium coated, plating alumina layer or plating silicon oxide layer
Laminated construction.
Preferably, the coating is formed in the base layer by chemical vapour deposition technique or physical vaporous deposition.
Preferably, the packaging adhesive film further includes protection adhesive layer, and the protection adhesive layer is formed in the transmitting barrier
On layer.
It is highly preferred that the packaging adhesive film is made of the base layer, the reflection barrier layer and the protection adhesive layer,
The base layer, the reflection barrier layer and the protection adhesive layer stack gradually.
Further, it is described protection adhesive layer with a thickness of 0.1-30 μm.
Further, the protection adhesive layer is formed on the reflection barrier layer by coating or printing.
Preferably, the base layer is EVA layer.
Another technical solution that the utility model uses are as follows:
A kind of solar cell module, including packaging adhesive film as described above.
The utility model uses above scheme, has the advantages that compared with prior art
It is laminated on the base layer of packaging adhesive film and is used as reflection barrier layer with a thickness of the coating of 8-500nm, it is with higher
Reflecting properties and barrier property to steam improve component generating efficiency, guarantee assembly life-span, and due to the thickness of coating compared with
Small (only 8-500nm), on lamination influence it is smaller, it is without exception after lamination, thus provide it is a kind of low cost, easily use,
The packaging adhesive film for the high reflection high-barrier solar cell module haveing excellent performance.
Detailed description of the invention
It, below will be to needed in embodiment description in order to illustrate more clearly of the technical solution of the utility model
