Abstract
The invention provides a photovoltaic module, an online packaging method thereof and an electronic component. The online packaging method comprises the following steps: the method comprises the following steps of sequentially stacking and laying a front glass layer, a front packaging adhesive film layer, a battery unit, a rear packaging adhesive film layer and a rear packaging material layer on line to obtain a laminated assembly, sequentially coating hot melt adhesive on the edge of the front glass layer, the battery string and the battery piece of the battery unit and at least part of the edge of the rear packaging material layer on line in the stacking and laying process, and laminating the laminated assembly to obtain the photovoltaic assembly, wherein the rear packaging material is glass or a back plate. The online packaging method can avoid the problem that photovoltaic modules are unqualified due to slippage among layers and parallel and serial connection of battery pieces caused by continuous increase of the speed of a production line, can reduce the reliability problems of delamination, bulging and the like of the photovoltaic modules caused by aging of the positioning adhesive tape, and further improves the yield of photovoltaic module products.
Description
Technical Field
The invention relates to the technical field of photoelectricity, in particular to a photovoltaic module, an online packaging method of the photovoltaic module and an electronic component.
Background
With the development of the industry, the production efficiency of photovoltaic modules is higher and higher, the structures of the photovoltaic modules are more and more diverse, and problems in the production process of some photovoltaic modules are gradually revealed and are increasingly sharp. If (1) skid easily between encapsulation glued membrane and the glass, along with the continuous improvement of subassembly production water line speed, the problem of skidding is more and more serious. After the adhesive film and the battery piece are laid, when the adhesive film is transferred to the next step and covered with a back plate or back glass, the adhesive film and the glass slide relatively, so that the problems that the adhesive overflows from one side and lacks from the other side, or the position of the battery piece deviates too close to the edge and even exceeds the edge of the glass easily occur, the degradation and the scrapping of the photovoltaic assembly are directly caused, and the operation pain point influences the speed increase of a photovoltaic assembly production line. For example, (2) the rubber film and the battery piece are easy to slip, which causes the position deviation of the battery piece and even the parallel connection and other problems. If (3) dual glass assembly lamination in-process, because four corners local pressure is big, overflow and glue many, the delaminating appears easily, problem such as bubble influences subassembly outward appearance and reliability.
At present, in order to prevent the movement between the battery strings, a positioning adhesive tape is attached to the position between the battery strings, but the positioning adhesive tape is poor in adhesion with an adhesive film, and reliability problems such as delamination and bulging are easy to occur in an aging process.
Disclosure of Invention
The invention mainly aims to provide a photovoltaic module, an online packaging method thereof and an electronic component, and aims to solve the problem that the photovoltaic module in the prior art is low in product yield due to slipping and the like in the online stacking and laying process.
