Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings：
A kind of novel photovoltaic module as shown in Figure 1, including photovoltaic module ontology and be connected with photovoltaic module body end
Frame 1；The photovoltaic module ontology includes the glass plate 2, the first EVA films 3, solar cell set gradually from up to down
Piece 4, the 2nd EVA films 5, insulating film 6, the 3rd EVA films 7 and backboard 8.On the 2nd EVA films 5 and the 3rd EVA films 7
It is respectively provided with cracking for solar battery sheet cabling.The backboard 8 is equipped with the trepanning for solar battery sheet cabling.
Preferably, the thickness of the 3rd EVA films is 0.5mm；The effect of 3rd EVA films is bonding insulating film and metal backing.
Further, the first EVA films are colourless film.The effect of first EVA films is bonding solar cell
Piece and glass plate, since photovoltaic cell can utilize ultraviolet light wave band, high light transmission EVA not to obstruct ultraviolet light so that luminous energy
Transmitance higher.In order to penetrate more light, the first EVA films do not use coloured film.
Further, 5, the 2nd EVA glue is white EVA films.White EVA films can obstruct ultraviolet light, protection
Insulating film does not fail.The effect of 2nd EVA films is the bonding for solar battery sheet and insulating film, in addition can also stop purple
Outside line.EVA films using white are the glass bounce back photovoltaic cells again in order to reflect more sunlight to glass surface（I.e. too
Positive energy battery）So that efficiency of light energy utilization higher.
Further, the frame 1 is equipped with slot.The laminated machine of photovoltaic module ontology evacuates forming layer after hot pressing
Shape structure, end are mounted in slot.Be coated with silicone adhesive on the surface of the slot, layer structure be directly embedded into be placed on it is slotting
In slot, after silicone adhesive curing, layer structure and the integral structure of frame shape.
Further, the glass plate 2 is tempered glass.The main function of glass plate is light transmission and protection, due to glass
Performance change will not occur because of the irradiation of sunlight, be used for the outermost protection materials of photovoltaic cell always.
Further, the first EVA films 3 are high light transmission EVA films.
Further, the insulating film 6 is using polyimides, makrolon, polyvinyl fluoride, polyethylene terephthalate
Any one in ester, polypropylene screen, organosilicon membrane material.
Further, the insulating film is PET film.The effect of insulating film is that the backboard of photovoltaic cell and metal material is exhausted
Edge, select PET film be because its is at low cost, it is good with the adhesive strength of EVA films.
Further, the backboard 8 uses metal or plastimets.Metal backing water resistant molecule infiltration performance
It is good, conductivity variations can not be caused by hydrone intrusion with protection packaging material, influence photovoltaic module power generation performance；Metal backing
Good heat dissipation can radiate as early as possible if hot spot occurs in photovoltaic module, and temperature accumulation is avoided to accelerate encapsulating material aging or failure；
The fire protecting performance of component can be made more excellent using metal backing.
