Abstract

The invention provides a multilayer packaging glue film for a solar cell and a preparing technology thereof, and particularly discloses a multilayer packaging glue film capable of effectively improving the anti-PID performance of a solar cell assembly and a preparing technology thereof.According to the specific formula proportion and the preparing technology, three glue films with different characteristics are compounded, the ion barrier performance, the insulativity and the water-vapor permeating barrier performance of the product are improved at the same time, and the anti-PID performance generated when the packaging glue film is used is further effectively improved.Compared with a traditional EVA packaging glue film in the market, the anti-PID performance generated when the product prepared with the preparing technology is used is obviously improved.

Description

technical field [0001] Technical Field Description Paragraph The present invention relates to a multi-layer encapsulation adhesive film for solar cells and its preparation process, especially a multi-layer encapsulation adhesive film that can effectively improve the anti-PID performance of solar cell modules and its preparation process. Background technique [0002] With people's emphasis on environmental protection and renewable energy, solar power generation has been rapidly developed as a new type of energy, and EVA packaging film has become the current solar cell due to its excellent light transmittance, bonding performance, processing performance, etc. The main packaging material. [0003] In recent years, the potential-induced power degradation (PID) of solar cells has attracted more and more attention. According to relevant research results, it is believed that there are many possible reasons for the PID phenomenon of components, such as the grounding method of the p...
