Problems solved by technology

In the harsh outdoor weather environment, if the quality of the polymer encapsulation film is not good, it will quickly age and turn yellow, or even degummed and cracked, causing the battery components to rupture or be eroded by the environment, resulting in a decrease in the photoelectric conversion efficiency of the entire battery component or Failure due to short circuit damage

Abstract

The invention relates to a solar energy packaging adhesive film, in particular, relates to an ultra-fast solidified solar energy packaging adhesive film and a preparation method thereof, and belongs to the field of photovoltaic packaging adhesive film, wherein the ultra-fast solidified solar energy packaging adhesive film is used for photovoltaic single-glass and double-glass assemblies. The solarenergy packaging adhesive film for reducing the lamination time is designed. The invention aims to reduce the vacuumization and lamination time of the photovoltaic assemblies in the packaging process, improve the efficiency and reduce the cost by adjusting the process, changing an auxiliary agent and improving the lamination temperature.

Description

Technical field [0001] The invention relates to a solar energy packaging adhesive film, in particular to an ultra-fast curing solar energy packaging adhesive film and a preparation method thereof, which are used for photovoltaic single glass and double glass components, and belong to the field of photovoltaic packaging adhesive films. Background technique [0002] With the depletion of energy and the deteriorating environment, governments of various countries have higher and higher requirements for energy saving and emission reduction. People urgently need a new energy to replace fossil fuels. Solar energy is a green, pollution-free and inexhaustible energy source. The solar energy industry has also become the focus of the development of various countries. Solar energy is converted into electricity through solar panels. Since the main working environment of the panels is outdoors, and the cells cannot be exposed to the sun or rain, they must be sealed with encapsulating materials....
