Description
Technical field
Photovoltaic module field is the utility model is related to, specifically a kind of double-sided glass photovoltaic module.
Background technology
Solar cell is the semiconductor devices to be generated electricity using sunshine, and solar battery chip can be amorphous
Silicon, amorphous silicon germanium, the single-unit or more piece laminated silicon-base film solar cell, CIGS solar-electricities of microcrystal silicon or nanocrystal silicon
Pond, copper and indium tin solar cell, indium sulphur solar cell, monocrystalline or quasi-monocrystalline silicon solar cell, polycrystalline silicon solar electricity
Pond, cadmium telluride solar cell, gallium arsenide solar cell, organic solar batteries, DSSC etc..It is existing
The TPT materials used in technology, have the disadvantage that:The service life of TPT materials is short, light tight, causes photovoltaic module
Service life is short, can not meet demand of the client to printing opacity.In addition, EVA adhesive film is to be currently used primarily in encapsulation solar cell
Material, but it comes with some shortcomings, and such as easy xanthochromia aging, weatherability is poor, service life is short.
Utility model content
The utility model provide it is a kind of there is cleaning, efficient, pollution-free, noiseless, do not discharge any be harmful to
The double-sided glass photovoltaic module of material.
A kind of photovoltaic module described in the utility model, including silicon wafer cell piece, in the upper and lower table of silicon wafer cell piece
PET composite membrane of the face encapsulation with three-decker, sets above the PET composite membranes of upper surface and below the PET composite membranes of lower surface
There is backboard, be provided with above the backboard above the PET composite membranes of upper surface and below the backboard of the lower section of lower surface PET composite membranes anti-
Photosphere, the lower section of the reflector layer above the backboard below the top of reflector layer and backboard are provided with photovoltaic glass, described photovoltaic glass
Glass outer surface is provided with radiation proof metallic film.
Further improve, described PET composite membranes are three-decker, by modified EVA/POE films and through sided corona treatment mistake
PET base material film two sides carry out pressing be combined.
Further improve, described modified EVA/POE films by fire-retardant EVA/POE resins and antioxidant using mass ratio as
100:0.1 ~ 1 is mixed to get jointly.
The beneficial effects of the utility model are：
The structure of double-sided glass photovoltaic module of the present utility model compared with common solar module, maximum difference
Being in instead of the lighttight TPT of short life with glass, greatly extending the life-span of photovoltaic module, and visitor can be met
The requirement of family printing opacity；In addition, the photovoltaic module has the characteristics that cleaning, efficient, pollution-free, noiseless, do not discharge any harmful
Material, belong to green product；Encapsulated using the PET composite membranes of three-decker instead of EVA adhesive film, there is the PET of three-decker
Composite membrane processing technology is simple, and cost is low, has excellent an anti-flammability and mechanical property, and good barrier, heat resistance,
Electrical insulating property and resistance to ag(e)ing, can have directly as the articulamentum for bonding backboard and cell piece as photovoltaic component encapsulating material
Potential application；Radiation proof metal film is additionally provided with outside glass so that the external radiativity of photovoltaic module is small.It is provided with backboard reflective
Layer, the sunshine that can be emitted onto marginal zone reflex to glass plate, and the sunshine is in glass plate through reflecting and reflecting again
On collected cell panel, the daylight rate of cell panel is effectively increased, so as to improve generating efficiency.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
A kind of photovoltaic module of the utility model, including silicon wafer cell piece 1, sealed on the upper and lower surface of silicon wafer cell piece
Harness has the PET composite membranes 2 of three-decker, and the lower section with lower surface PET composite membranes above the PET composite membranes of upper surface is provided with the back of the body
Plate 3, it is provided with above the backboard above the PET composite membranes of upper surface and below the backboard of the lower section of lower surface PET composite membranes reflective
Layer 4, the lower section of the reflector layer above the backboard below the top of reflector layer and backboard are provided with photovoltaic glass 5, described photovoltaic glass
Glass outer surface is provided with radiation proof metallic film 6.
Described PET composite membranes are three-decker, the PET base material film crossed by modified EVA/POE films and through sided corona treatment
Two sides carry out pressing be combined；Described modified EVA/POE films are by fire-retardant EVA/POE resins and antioxidant with quality
Than for 100:0.1 ~ 1 is mixed to get jointly.
The utility model concrete application approach is a lot, and described above is only preferred embodiment of the present utility model, should
Point out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also make
Go out some improvement, these improvement also should be regarded as the scope of protection of the utility model.
