Using Mirror yellow PE film For Daily Use can significantly protect photovoltaic modules from the risk of PID. PID is an important issue in the photovoltaic industry. It describes that when photovoltaic modules are operated outdoors for a long time, due to the combined effect of a variety of external factors, the internal packaging materials, EVA (ethylene vinyl acetate copolymer) film or The phenomenon of chemical or physical changes in key components such as backplanes.
The PID phenomenon usually occurs between the packaging material of the module and the cell. Due to the combined effect of factors such as humidity, temperature fluctuations, and voltage stress, it may cause ion migration in the packaging material, which in turn causes the performance of the cell to decline. This performance degradation may manifest as power attenuation and efficiency reduction of the component, and may even affect the long-term stability and reliability of the component.
Mirror yellow daily-use PE film can effectively deal with PID risks through its unique material and structural design. First, its surface treatment and coating technology can isolate or reduce direct contact between external factors such as humidity and the internal structure of the component, thereby reducing the probability of PID phenomena. Secondly, the polymer structure of the PE film makes it have excellent weather resistance and stability, and can maintain its performance under various harsh environmental conditions, further extending the service life of photovoltaic modules.
Mirror yellow daily-use PE film also has a series of other advantages, such as superior weather resistance (including high temperature, high humidity, ultraviolet light, etc.), excellent adhesive properties after aging, and excellent light transmittance (to ensure the power generation efficiency of the module) , low shrinkage (to ensure stable quality during the lamination process) and good operability and stability during the lamination process. These characteristics make Mirror yellow PE film For Daily Use an ideal choice to protect photovoltaic modules from PID risks and improve module performance and stability.
