The utility model discloses a high moisture -proof hot photovoltaic module's electrically conductive backplate, through the water blocking layer that increases in case stagnant water vapour to the destruction of photovoltaic module backplate, easily bond simultaneously.
Description
Technical field
This utility model relates to the conductive backings of a kind of photovoltaic module, is specifically related to the conductive backings of a kind of high wet-heat resisting photovoltaic module.
Background technology
Conventional solar cell assembly composite conductive rear panel is generally made up of polymeric layer, PET, Copper Foil, bonding by bonding agent between layers.Although conductive backings water is the lowest, steam is difficult to penetrating metal layer and enters dielectric layer, but steam can constantly corrode the layer on surface of metal of PET side through pet layer, metal level is made to be corroded, metal ion can constantly separate out entrance adhesive linkage, makes adhesive linkage insulation breakdown, leaks electricity.And assembly is chronically at energising duty, under electrochemical reaction effect, metal ion can constantly separate out, and finally results in the adhesive linkage between Copper Foil and PET and occurs that conductive path makes component failures.
For solving conductive backings electrical leakage problems, current most of backboards add ion capturing agent in adhesive linkage, and complexation of metal ions reduces free ion concentration.But, ion capturing agent exists and poor compatibility in glue-line, affects the shortcomings such as glue-line adhesive strength, and ion capturing agent belongs to expendable material simultaneously, and in actual use, ionic additive runs out of soon, it is impossible to the protection that assembly is lasting.
Utility model content
Problem to be solved in the utility model is to provide the conductive backings of a kind of high wet-heat resisting photovoltaic module, by the water blocking layer of increase to prevent the water vapour destruction to photovoltaic component back plate, is prone to bonding simultaneously.
For achieving the above object, the technical scheme that this utility model is taked is as follows: the conductive backings of a kind of high wet-heat resisting photovoltaic module, described conductive backings is compounded with outer layer weathering layer, supporting layer, water blocking layer, conductive layer and dielectric layer the most successively, and it is additionally provided with adhesive linkage between each layer, described water blocking layer is metal or metallic oxide film, and its thickness is 1～50 μm.
Described outer layer weathering layer is PVF film, pvdf membrane, the one in fluoro-containing coating or weather-proof PET material, and thickness is 18～40 μm.
Described support layer material is the one in PET, PA, PP, and thickness is 100～400 μm.
Described conductive layer is Copper Foil or aluminium foil, and thickness is 10～200 μm.
The preferred aluminium foil of described water blocking layer, the one in iron foil, tinfoil paper, zinc paper tinsel, nickel foil, Copper Foil, native silver, platinum foil, native gold, pin hole quantity is less than 10 every square metre, and aperture is not more than 0.1mm.
Beneficial effect: the conductive backings of a kind of high wet-heat resisting photovoltaic module disclosed in this utility model, metal is added or water blocking layer prepared by metal-oxide in conventional solar energy backboard, because metal or metal-oxide have the most bonding, higher to water oxygen-barrier property, ductility is good, it is prone to the advantages such as processing, make the water vapor transmittance of water blocking layer less than 0.1g/m2*day, can effectively prevent steam enter thus etching conductive layer metal causes photovoltaic component back plate to damage, in addition, metal and metal-oxide block water and have good heat conductive performance, backboard thermal conductivity can be improved, reduce module operating temperature, improve generating efficiency, component internal temperature additionally can be made homogeneous, improve backboard resistance to hot spot performance, adhesive effect is improve while the burning that dielectric layer can effectively prevent conductive layer.
