Abstract
The utility model relates to an EVA (ethylene vinyl-acetate copolymer) adhesive film for a solar photovoltaic module, which comprises a solar cell lamination part, wherein the solar cell lamination part is sequentially composed of a back plate, a first adhesive film layer, a solar cell, a second adhesive film layer and coated toughened glass; and the upper surface and the lower surface of the first adhesive film layer and the second adhesive film layer are respectively provided with an embossed pattern. Due to the EVA adhesive film having an embossed structure, the EVA adhesive film for a solar photovoltaic module ensures that the adhesive film rolled up can not be subjected to adhesion, and has better adhesion property when adhering to the solar cell. Besides, the EVA adhesive film is simple in structure and high in durability.
Description
Technical field
The utility model relates to the field of solar photovoltaic assembly, and especially a kind of solar photovoltaic assembly is used the EVA glued membrane.
Background technology
Solar cell need be laid the glued membrane that one deck is processed by the EVA material between glass outer and solar cell when encapsulation, this glued membrane is in the solar cell package process; Curing reaction takes place; Become the water white transparency shape, the glued membrane solidification process need be discharged the air between glass outer and the solar cell; The comprehensive light transmittance of cured glue film and glass outer is more taller than the light transmittance that is merely glass outer, and the photoelectric conversion efficiency of solar cell also is improved.
In the field of solar components, what at present traditional glued membrane adopted is the EVA glued membrane, but the upper strata and the bottom of the glued membranes that great majority use all are smooth layer, and it is not high to make the adhesion of its glued membrane close durability, phenomenons such as easy ageing.
Summary of the invention
The utility model technical issues that need to address are: in order to overcome the above-mentioned middle problem that exists, provide a kind of solar photovoltaic assembly to use the EVA glued membrane, it has stronger adhesion and closes durability.
The utility model solves the technical scheme that its technical problem adopted: a kind of solar photovoltaic assembly is used the EVA glued membrane; Comprise lamination part of solar cell; Described lamination part of solar cell is made up of backboard, first adhesive film, solar battery sheet, second adhesive film and coated toughened glass successively, and the upper surface and the lower surface of described first adhesive film, second adhesive film are equipped with the embossing decorative pattern.
First adhesive film and second adhesive film all are to adopt the EVA glued membrane to process; The EVA glued membrane is a kind of heat cured membranaceous PUR; Be not clamminess under the normal temperature, be convenient to operation, under molten condition; It produces to bond with silicon wafer, glass, TPT becomes solar panel; EVA is the copolymer of ethene and vinyl acetate, has good pliability, resistance to impact, elasticity, optical transparence, low temperature around song property, adherence, environmental stress crack resistance, weatherability, corrosion resistance, heat seal property and electrical property etc., and the performance of EVA depends primarily on the content of molecular weight (can represent with melt index M worker) and vinylacetate (representing with VA).When M worker's one timing, the content of VA increases, and the elasticity of EVA, flexibility, caking property, intermiscibility and the transparency improve; The content of VA reduces, and EVA then approaches poly performance, and when one timing of VA content, molecular weight reduces then softening point decline, and processability and lustrous surface are improved, but intensity reduces; Divide in amount to increase, can improve resistance to impact and stress cracking property, be used to encapsulate the EVA of silicon solar cell assembly, mainly according to light transmission be processed into film properties and select.
For can be at adhesion between the glued membrane after the glued membrane rolling, described embossing decorative pattern be to adopt the protruding decorative pattern of polygon.
The thickness of described first adhesive film and second adhesive film is 0.5～0.8mm.
The beneficial effect of the utility model is: described solar photovoltaic assembly is used the EVA glued membrane; Adopt the EVA glued membrane of decorative pattern formula structure; Can make after the glued membrane rolling adhesion and can stick to have better adhesiveness on the solar cell, it is simple in structure, and durability is high.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the overall structure sketch map of the described solar photovoltaic assembly of the utility model with the EVA glued membrane;
Fig. 2 is the structural representation of first adhesive film and second adhesive film among Fig. 1.
Accompanying drawing acceptance of the bid is kept the score and is stated as follows: 1, backboard, 2, first adhesive film, 3, solar battery sheet, 4, second adhesive film, 41, the embossing decorative pattern, 5, coated toughened glass.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the sketch map of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Solar photovoltaic assembly as depicted in figs. 1 and 2 is used the EVA glued membrane; Comprise successively by backboard 1, thickness being that first adhesive film 2, solar battery sheet 3, the thickness of 0.6mm is second adhesive film 4 of 0.6mm and the lamination part of solar cell that coated toughened glass 5 is formed; The upper surface and the lower surface of first adhesive film 2 and second adhesive film 4 are equipped with embossing decorative pattern 41; Embossing decorative pattern 41 is the protruding decorative pattern of polygon, and first adhesive film 2 and second adhesive film 4 all adopt the EVA glued membrane to process.
The described solar photovoltaic assembly of the utility model is used the EVA glued membrane; Select the EVA glued membrane of 0.6mm for use; The upper epidermis of EVA glued membrane goes out the protruding decorative pattern of polygon with following top layer through the roller pressure roller, and it can prevent between the glued membrane bonding when rolling EVA glued membrane; And can when solar cell and backboard and toughened glass lamination, can improve adhesiveness, and improve durability effectively.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
