The sealing property of filling meaning component edge.At present, for the steam for reducing or avoiding component edge permeates, industry
Typically lamination can be packaged using butyl rubber, but butyl rubber can flow to component internal during lamination, after causing lamination
Easily there is irregular phenomenon, so as to cause the open defect of photovoltaic module, and this defect to repair so that
Whole photovoltaic module can only be scrapped, and cause the great wasting of resources.
Utility model content
In view of this, the utility model provides a kind of photovoltaic module, and sealing joint strip inwardly flows during it can improve lamination process
Problem that is dynamic and polluting photovoltaic cell string.
Specifically, the utility model is achieved by the following technical solution：A kind of photovoltaic module, including from top to bottom layer
The folded cover plate for setting, upper strata glued membrane, photovoltaic cell string, lower floor's glued membrane and backboard, the photovoltaic module also include being located at it is described under
The sealing joint strip of layer glued membrane circumferential periphery and the barrier layer between lower floor's glued membrane and sealing joint strip.
Further, the barrier layer is surrounded on the periphery of lower floor's glued membrane, and barrier layer and the sealing joint strip it
Between be provided with gap.
Further, the width in the gap is 1-2mm, and the width of the sealing joint strip is 5-10mm, thickness is 1-
2mm。
Further, 1/3rd of the width on the barrier layer no more than the sealing joint strip width.
The utility model by setting a barrier layer on the inside of sealing joint strip, can prevent and treat sealing joint strip in lamination process to
Photovoltaic module inner side flowing, it is to avoid its pollution to photovoltaic cell string, has prevented open defect.

As shown in Figures 1 and 2, the utility model discloses a kind of photovoltaic module, including the cover plate being from top to bottom stacked
10th, upper strata glued membrane 20, photovoltaic cell string 30, lower floor's glued membrane 40 and backboard 50, the layer that foregoing each material part passes through laminating machine
Pressure is acted on, and forms the photovoltaic module of one.
In the utility model preferred embodiment, the cover plate 10 is for clear glass and with embossing basal surface, the back of the body
Plate 50 is also clear glass.The upper strata glued membrane 20 and lower floor's glued membrane 40 are preferably EVA (ethene-vinyl acetate copolymer),
Its upper and lower both sides for being located at photovoltaic cell string 30 respectively, and the upper strata glued membrane 20 and the rectangular sheet of lower floor's glued membrane 40, its
Size is suitable with the size of photovoltaic cell string 30 but less than the size of the backboard 50, before being laminated, it is necessary to by the light
Volt battery strings 30 are positioned on lower floor's glued membrane 40, and the upper strata glued membrane 20 then is layed in into the photovoltaic cell string 30 again
On, finally cover the cover plate 10.
In order to increase the air-tightness of photovoltaic module edge, photovoltaic module described in the utility model is also included positioned at described
The sealing joint strip 60 of the circumferential periphery of lower floor's glued membrane 40, the sealing joint strip 60 is in square along the edge distribution of the backboard 50
Shape, the inner side for making sealing joint strip 60 by the clamping of cover plate 10 and backboard 50 forms sealing state, so as to prevent extraneous steam from entering
Enter inside the photovoltaic module, the preferred butyl rubber of the sealing joint strip 60, the preferred 5-10mm of its width, the preferred 1-2mm of thickness.Together
When, in order to prevent sealing joint strip 60 from deforming or flowing to photovoltaic module in photovoltaic module lamination process, the utility model is preferable
In embodiment, the surrounding of lower floor's glued membrane 40 is additionally provided with barrier layer 70, and the barrier layer 70 is surrounded on lower floor's glued membrane 40
Periphery and between lower floor's glued membrane 40 and sealing joint strip 60, so can be using barrier layer 70 come baffle seal adhesive tape
60 flow to photovoltaic module inner side, and the color on the barrier layer 70 is identical with the color of the sealing joint strip 60, and preferably without
Cloth or soft PVC material are spun, therefore, even if flow to also will not be to barrier layer on the barrier layer 70 for sealing joint strip 60
70 cause outward appearance to pollute, because both colors are identical, it is worth mentioning at this point that, the width on the barrier layer 70 is no more than described close
/ 3rd of the width of seal strip 60.
In addition, retained between the barrier layer 70 and the sealing joint strip 60 having gap 80, the width in the gap 80 is excellent
Elect 1-2mm as, be arranged such and stopped space to the flowing of sealing joint strip 60, make it farther away from photovoltaic cell string 30, so that
It is avoided to be polluted to photovoltaic cell string 30 to being flowed in photovoltaic module.
It can be seen that, the utility model sets a barrier layer 70 by the inner side of sealing joint strip 60, can prevent and treat sealing joint strip 60 and exist
Flowed to photovoltaic module inner side in lamination process, it is to avoid its pollution to photovoltaic cell string 30, prevented open defect.
Preferred embodiment of the present utility model is the foregoing is only, is not used to limit the utility model, it is all at this
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements done etc. should be included in the utility model
Within the scope of protection.
