Abstract
The utility model relates to the technical field of solar cells, specifically to a packaging film for an EVA (Ethylene/vinyl Acetate) solar cell component, comprising a plastic film, wherein the plastic film is an EVA film, and raised polygonal patterns are pressed on any surface of the EVA film. The packaging film for the EVA solar cell component plays a role of increasing light transmission, preventing moisture and resisting ultraviolet rays for the solar component. Due to the raised patterns pressed on the EVA film, films can be prevented from being adhered with each other, enough channels are arranged between the EVA film and the cell component for the subsequent vacuumization, and the air between the cell components can be completely removed, so that the service life of the solar cell component is ensured.
Description
Technical field
The utility model relates to technical field of solar batteries, is specifically related to a kind of EVA solar module encapsulating film.
Background technology
Solar module (also being solar panel) is the core in the solar power system, also is to be worth the highest part in the solar power system.Its effect is to be electric energy with conversion of solar energy, or is sent in the storage battery and stores, or promotes loaded work piece; Its center is the battery sheet, and the two-layer up and down of battery sheet is packaging adhesive film.Wherein, encapsulating film is to be used for solar battery sheet is sealed between the glass and backboard of solar panel, makes it not receive the erosion of moisture and air.Encapsulation for ease, existing packaging adhesive film mostly adopts two-sided smooth structure, because the characteristic of membrane material itself, the product of processing generally all can have certain viscosity, when rolling, causes the adhesion between film and the film easily, makes troubles for the practicality of product; The contact area of the encapsulating film of this smooth surface and battery component is big in addition; The exhaust passage is few, is unfavorable for operation that solar cell is vacuumized, fully deaeration; Thereby can influence the outward appearance of solar module, even more serious meeting influences solar module useful life.
The utility model content
In order to overcome the deficiency of prior art, the purpose of the utility model is to provide a kind of transparency height, the vapour that blocks water, EVA solar module encapsulating film that uvioresistant is strong, and can prolong the useful life of solar module.
For addressing the above problem, the technical scheme that the utility model adopted is following:
A kind of EVA solar module encapsulating film comprises the glue facial mask, and said glue facial mask is EVA (ethylene-vinyl acetate copolymer) film, and the EVA film is pressed with protruding polygon decorative pattern on the one side arbitrarily.
In order to prevent that effectively encapsulating film from not producing adhesion between film and the battery component between film and the film and when mounting when the rolling, make things convenient for the practicality of product, in the preferred scheme of the utility model, said EVA film two sides all is pressed with the decorative pattern of multiform.
Polygon decorative pattern of the present invention can be triangle, quadrangle, pentagon or the like, can look the difficulty of processing and decide; In order to reduce the difficulty of processing, in the preferred scheme of the utility model, said polygon decorative pattern is a hexagon.
In the preferred scheme of the utility model, described EVA film thickness is 0.05-0.5mm.
As preferably, the thickness of the said polygon decorative pattern of the utility model on the EVA face is 0.05-0.2mm.
Compare prior art, the beneficial effect of the utility model is: the EVA solar module encapsulating film of the utility model its to solar components play anti-reflection light, the vapour that blocks water, anti-ultraviolet effect; The utility model is through can effectively preventing the adhesion between film and the film at the protruding decorative pattern of compacting on the EVA face; And make have enough passages to make things convenient for the follow-up step that vacuumizes between EVA film and the battery component; Can get rid of the air between the battery component fully, thereby guarantee the useful life of solar module.In addition, the utility model good looking appearance, processing are simply.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Description of drawings
Fig. 1 is the EVA solar module encapsulating film structural representation of the utility model preferred embodiment.
Embodiment
As shown in Figure 1, the EVA solar module encapsulating film of the utility model comprises the glue facial mask, and said glue facial mask is an EVA film 1, and EVA film 1 is pressed with protruding polygon decorative pattern 2 on the one side arbitrarily.
In order to prevent that effectively encapsulating film from not producing adhesion between film and the battery component between film and the film and when mounting when the rolling, make things convenient for the practicality of product, in preferred embodiment of the utility model, said EVA film two sides all is pressed with the decorative pattern of multiform.
Polygon decorative pattern 2 of the present invention can be triangle, quadrangle, pentagon or the like, can look the difficulty of processing and decide; In order to reduce the difficulty of processing, in preferred embodiment of the utility model, said polygon decorative pattern is a hexagon.
In preferred embodiment, the described EVA film thickness of the utility model is 0.05-0.5mm.
In another preferred embodiment, the thickness of the said polygon decorative pattern of the utility model on the EVA face is 0.05-0.2mm.
The foregoing description is merely the preferred case study on implementation of the utility model; Can not limit the utility model scope required for protection with this, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement all belong to the utility model scope required for protection.
Claims (5)
