Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Photovoltaic cell modules are often installed outdoors, and the outdoor climate has a great influence on the operating life of the photovoltaic cell module, wherein water vapor is a great influencing factor. In order to prevent the erosion of the water vapor to the photovoltaic cell assembly, except for adopting the traditional packaging material to package the photovoltaic cell, the aim of preventing the erosion of the water vapor to the photovoltaic cell assembly is fulfilled by improving the water blocking performance of the sealant for bonding the outer frame. Also disclosed in the patent publication No. CN205039164U is a dual-glass photovoltaic module comprising a cover plate, a back plate, a battery piece positioned between the cover plate and the back plate, and a sealing strip positioned at the periphery of the battery piece; the sealing strips are distributed along the peripheral edges of the backboard and are positioned between the cover plate and the backboard, and each sealing strip comprises a middle interlayer, and an upper hot melt adhesive layer and a lower hot melt adhesive layer which are respectively positioned on the upper side and the lower side of the middle interlayer. It should be noted that the above-mentioned packaging material includes a packaging adhesive film and a packaging cover plate, and the packaging cover plate also includes a front cover plate and a rear cover plate.
The scheme only seals the periphery of the photovoltaic cell assembly, and the problem that once the water vapor breaks through the seal of the periphery, the water vapor enters the photovoltaic cell assembly, and the photovoltaic cell assembly is not provided with an effective water blocking element or can not continuously prevent the corrosion of the water vapor to the photovoltaic cell assembly is solved.
In order to solve the above-mentioned problems, referring to fig. 1, an embodiment of the present utility model provides a high water-blocking photovoltaic cell assembly, which includes a packaging material 10 and a plurality of battery serial structures 20, wherein the plurality of battery serial structures 20 are distributed in a rectangular shape to form a battery serial structure matrix, water-blocking adhesive tapes 30 are disposed around the battery serial structure matrix, water-blocking adhesive tapes 30 are disposed at gaps of the battery serial structures 20, and the water-blocking adhesive tapes 30 and the battery serial structures are sandwiched between the packaging material 10. The water blocking adhesive tape 30 is arranged at the gap between the battery serial structures 20, so that when water vapor breaks through the water blocking adhesive tape 30 arranged around the battery serial structure matrix, the water vapor can be prevented from further corroding the photovoltaic battery assembly, and the generation power of the photovoltaic battery assembly is prevented from being greatly reduced due to the influence of the water vapor. It should be noted that, the packaging material 10 may be divided into a packaging film and a packaging cover plate, and the packaging cover plate may be divided into a front cover plate and a rear cover plate. In the lamination process of the photovoltaic module, the packaging adhesive film is heated and melted and fills all gaps in the battery array under the action of pressure, so that the packaging adhesive film must have enough thickness to fill all gaps and a certain margin to bond the cover plate, otherwise, bubbles are generated due to incomplete filling of the packaging adhesive film, or the bonding force between the packaging adhesive film and the cover plate is smaller than the stress generated by rebound or deformation of the cover plate (especially glass) due to insufficient margin of the packaging adhesive film, so that vacuum bubbles are formed. Therefore, the water blocking adhesive tape 30 is arranged at the gap between the battery serial structures 20, which is equivalent to prefilling the gap between the battery serial structures 20, and accordingly, the thickness of the packaging adhesive film can be properly reduced, so that the overall quality of the photovoltaic module can be reduced, the installation place with higher overall quality requirement on the photovoltaic module can be adapted, and meanwhile, the cost can be reduced. The water blocking tape 30 can be adapted to any of the battery serial structures 20, for example: the cell series structure 20 may be a conventional cell series structure (as shown in fig. 4), a shingled cell series structure (as shown in fig. 7), a linear film cell series structure (as shown in fig. 8), and a plated electrode cell series structure (as shown in fig. 5 and 6).
Further, the difference between the height of the water blocking tape 30 and the height of the battery serial structure 20 is 0 μm to 200 μm. Furthermore, the height of the water blocking adhesive tape 30 is smaller than or equal to the height of the battery serial structure 20, so that water vapor can be prevented from entering the inside of the battery serial structure 20 from the edge of the photovoltaic module by arranging the water blocking adhesive tape 30, short circuit of the battery can be avoided, the packaging material 10 can be supported by limiting the height of the water blocking adhesive tape 30, a space is supported for the battery serial structure 20, and hidden crack or damage caused by stress action of the battery in the battery serial structure 20 in the laying process or the laminating process can be prevented. The height of the water-blocking adhesive tape 30 can be set according to the thickness of the packaging adhesive film, so that the synergistic effect of the water-blocking adhesive tape 30 and the packaging adhesive film can be fully exerted, the optimal effect is ensured, and the material is not wasted. Preferably, the water-blocking adhesive tape 30 is made of POE (ethylene- α -olefin polymer), and the POE adhesive film has excellent waterproof (permeation) capability, and has stronger vapor permeation resistance and corrosion aging resistance than EVA adhesive film.
Further, regarding the position where the water blocking tape 30 is provided, two embodiments are provided below.
As shown in fig. 1, the water blocking adhesive tape 30 may be disposed at a gap between the battery serial structures 20, the water blocking adhesive tape 30 and the battery serial structures 20 are sandwiched between the packaging materials 10, and in this embodiment, the height of the water blocking adhesive tape 30 is equal to the height of the battery serial structures 20. Preferably, the packaging material 10 includes a packaging adhesive film and a packaging cover plate, when the water-blocking adhesive tape 30 is disposed at the gap between the battery serial structures 20, the water-blocking adhesive tape 30 can be used for prefilling the gap to protect the battery and prevent the battery from being hidden and broken, and meanwhile, the packaging adhesive film can be properly thinned, so that the weight of the whole photovoltaic module is reduced, and the whole cost is saved.
