Problems solved by technology

In this technical solution, the backplane, the first adhesive film, the battery sheet, the second adhesive film and the cover plate need to be heated twice before forming the laminate, and the steps are cumbersome, and the first temperature used in the packaging method 120-200°C, the lamination temperature is higher, and the energy consumption is larger
[0006] In the prior art, when the photovoltaic modules are prepared by the lamination process, the lamination temperature used is relatively high, but with the development of cell technology, some new technology cells produced and prepared are sensitive to heat (such as perovskite cells) , needs to be packaged under the condition of ≤110°C, and the lamination process in the prior art is not suitable for photovoltaic components that require low-temperature packaging

Abstract

The invention provides a packaging adhesive film and a preparation method and application thereof. The packaging adhesive film comprises the following raw material components: matrix resin, a cross-linking agent, an assistant cross-linking agent, a silane coupling agent and a light stabilizer, the assistant cross-linking agent comprises a combination of an isocyanate assistant cross-linking agent and an acrylate assistant cross-linking agent; the mass ratio of the isocyanate assistant crosslinker to the acrylate assistant crosslinker is 1 : (0.2-5). The preparation method comprises the following steps: mixing the matrix resin, the cross-linking agent, the assistant cross-linking agent, the silane coupling agent and the light stabilizer as well as the optional filler, the photoinitiator, the silane coupling agent, the ultraviolet absorber and the anti-PID aid, and extruding the mixture to obtain the packaging adhesive film. When the packaging adhesive film is used for preparing the photovoltaic module, the proper crosslinking degree can be provided, the lamination temperature can be reduced, the lamination time can be shortened, and the problems of higher curing temperature and higher energy consumption of the packaging adhesive film in the preparation process of the photovoltaic module can be solved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic equipment, and in particular relates to an encapsulating adhesive film and a preparation method and application thereof. Background technique [0002] Since the birth of life on the earth, it has mainly lived on the thermal radiation energy provided by the sun, and since ancient times, human beings have also known how to use sunlight to dry objects and make food. With fossil fuels decreasing day by day, solar energy has become an important part of the energy used by human beings and has been continuously developed. Photovoltaic modules, namely solar cells, are devices that directly convert solar energy into electrical energy. Improving the power output of photovoltaic modules is a basic direction of solar photovoltaic module packaging. The encapsulation film mainly seals and protects solar cells, and plays an important role in photovoltaic modules. Common encapsulation films are heat-cured a...
