Poe film and Eva film are two common choices in the selection of photovoltaic backplane adhesive film. Although their functions are similar, there are significant differences in their applications. Let's take a closer look at the characteristics and application differences of these two thin films.
Poe adhesive film
Poe adhesive film is a kind of material copolymerized by polyethylene and polypropylene, which has the advantages of high temperature resistance, low temperature resistance, ultraviolet resistance, aging resistance, etc. In the application of photovoltaic backplane adhesive film, Poe adhesive film is mainly used for the back protection of solar panels. It can effectively prevent surface pollution and oxidation of the battery board, and extend the service life of the battery board. Poe adhesive film also has good transparency, which can improve the light energy utilization rate of solar panels.
Eva adhesive film
Eva film is a material made by copolymerization of ethylene and vinyl acetate, which has excellent weather resistance, corrosion resistance, UV resistance, and flexibility. In the application of photovoltaic back panel adhesive film, Eva adhesive film is mainly used for back panel packaging of solar panels. It can effectively prevent water vapor infiltration of the battery panel and protect it from moisture and corrosion. Eva adhesive film also has good adhesion performance, which can effectively fix the battery board and back board, improve the mechanical strength and stability of the battery board.
difference
Although Poe film and Eva film can play important roles in photovoltaic backplane applications, there are still significant differences in their application. Mainly manifested in the following aspects:
1. Different application ranges
Poe adhesive film is mainly used for the back protection of solar panels, while Eva adhesive film is mainly used for the back panel packaging of solar panels. The application scope of the two types of thin films is different, so it is necessary to choose according to the actual situation in specific applications.
2. Performance differences
Although Poe film and Eva film have excellent weather resistance, corrosion resistance, and UV resistance, their performance differences are still significant. Poe adhesive film has good transparency, which can improve the light energy utilization rate of solar panels; And Eva adhesive film has good adhesion performance, which can effectively fix the battery board and back board, improve the mechanical strength and stability of the battery board.
3. Different prices
Due to the different production processes and raw materials of Poe film and Eva film, their prices also vary greatly. Generally speaking, the price of Eva film is slightly higher than that of Poe film.
conclusion
In summary, the differences between Poe film and Eva film in the application of photovoltaic backplane film mainly lie in three aspects: application scope, performance, and price. In specific applications, it is necessary to make choices based on the actual situation. If it is necessary to improve the light energy utilization rate of solar panels, Poe adhesive film can be chosen; If it is necessary to improve the mechanical strength and stability of the battery panel, Eva adhesive film can be chosen. No matter which type of thin film is chosen, it is necessary to ensure that its quality and performance meet the requirements in order to effectively improve the efficiency and reliability of solar photovoltaic power generation.
