Description
Technical field
The utility model relates to photovoltaic art more particularly to a kind of photovoltaic modulies.
Background technique
As the requirement in the industry to photovoltaic module generated output is higher and higher, the scheme for increasing component power emerges one after another,
For example welding is thickeied, or use reflective solder strip, reflective pad pasting etc., but either any scheme, it requires to increase encapsulating material
The thickness of (EVA or POE etc.) solves the problems, such as that welding thickness increases, and then will lead to integrity problem, in this way, in photovoltaic
While component proposes effect, the increase of component cost is also brought.
Utility model content
In view of this, the present invention provides a kind of photovoltaic modulies, to improve integrity problem existing in the prior art
And the problem of higher cost.
Specifically, the utility model is achieved by the following technical solution: a kind of photovoltaic module, including battery strings, position
Upper layer packaging adhesive film above battery strings and lower layer's packaging adhesive film below battery strings, the upper layer packaging adhesive film is under
Layer packaging adhesive film is equipped with the inner surface towards battery strings, and protrusion has several thickening parts on the inner surface.
Further, the battery strings include the welding of several cell pieces and the concatenation cell piece, the welding and institute
Thickening part is stated to be arranged in a one-to-one correspondence.
Further, the quantity of the thickening part is identical as the quantity of the welding, and thickening part is pressed on the welding
Surface.
Further, the width of the thickening part is greater than the width of the welding.
Further, recess portion, the region phase between the recess portion and adjacent two welding are formed between two neighboring thickening part
It is corresponding.
The utility model makes to thicken by thickening part will be arranged on the inner surface of upper layer packaging adhesive film and lower layer's packaging adhesive film
Portion is pressed on welding surface, can effectively solve the bad problem of bring reliability due to the increase of welding thickness, and without adding
Thick entire packaging adhesive film, need to only thicken at the corresponding position of welding, reduce production cost to a certain extent.
Detailed description of the invention
Fig. 1 is the schematic diagram of internal structure of photovoltaic module described in the utility model.
Specific embodiment

The example of the consistent device and method of some aspects be described in detail in the appended claims, the utility model.
It is only to be not intended to be limiting this reality merely for for the purpose of describing particular embodiments in the term that the utility model uses
With novel.In the "an" of the utility model and singular used in the attached claims, " described " and "the"
Most forms are intended to include, unless the context clearly indicates other meaning.It is also understood that term used herein " and/
Or " refer to and include that one or more associated any or all of project listed may combine.
It please join shown in Fig. 1, the utility model provides a kind of photovoltaic module comprising be from top to bottom sequentially overlapped the lid of setting
Plate 10, upper layer packaging adhesive film 20, battery strings 30, lower layer's packaging adhesive film 40 and backboard 50.The cover board 10 and backboard 50 are laminated
The upper layer packaging adhesive film 20, battery strings 30 and lower layer's packaging adhesive film 40 are pressed into an entirety after technique, wherein the electricity
Pond string 30 includes the welding 32 of several cell pieces 31 and the concatenation cell piece 31, and the welding 32 is respectively connected to two neighboring
The front and back of cell piece 31 is realized and is electrically connected with the electrode of 31 front and back of cell piece.
In the utility model preferred embodiment, the upper layer packaging adhesive film 20 and lower layer's packaging adhesive film 40 are equipped with direction
The inner surface 60 of cell piece 31, protrusion has several thickening parts 61 on the inner surface 60, and the thickening part 61 is towards the battery
31 direction of piece protrudes out, and is arranged in a one-to-one correspondence with the welding 32 on 31 surface of cell piece, for being pressed in the surface of the welding 32.
The quantity of the thickening part 61 is identical as the quantity of the welding 32, and the width of thickening part 61 is slightly larger than the width of the welding 32
Degree.Recess portion 62 is formed between two neighboring thickening part 61, the region between recess portion 62 and adjacent welding 32 is corresponding.
The utility model passes through on the inner surface 60 by least one of upper layer packaging adhesive film 20 and lower layer's packaging adhesive film 40
Thickening part 61 is set, so that thickening part 61 is pressed on 32 surface of welding, the thickness of thickening part 61 is thicker than the other positions of packaging adhesive film
Thickness, being pressed in 32 surface of welding can effectively solve the bad problem of bring reliability due to the increase of 32 thickness of welding, for weldering
Thickness increase with 32 provides advantage, and without entire packaging adhesive film is thickeied, only need to be in the corresponding position of welding 32
It sets place to thicken, reduces production cost to a certain extent.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should be included in the utility model
Within the scope of protection.
