Mirror yellow film For Daily Use

How does Mirror yellow film effectively protect modules from PID (potential induced degradation) risk?

Mirror yellow film plays a key role in the photovoltaic industry, its design and performance are designed to effectively protect photovoltaic modules from the risk of PID (Potential Induced Degradation). PID is a phenomenon that can lead to degradation of photovoltaic module performance, usually caused by ion migration caused by the potential difference between the cells and the frame. Mirror yellow film significantly reduces the risk of PID through a series of unique features and designs, thereby ensuring the long-term stable operation of photovoltaic modules.
First of all, Mirror yellow film is very particular about material selection. It may be made from specially formulated polymer materials that provide excellent electrical insulation and chemical stability. These properties enable the film to effectively prevent ion migration, thereby reducing the occurrence of PID effects. In addition, these materials have excellent weather resistance and can maintain stable performance in harsh environments such as high temperature, high humidity and UV rays.
Secondly, Mirror yellow film has superior isolation performance. It is usually designed to cover the cells of a photovoltaic module, forming a protective barrier. This barrier effectively isolates the direct contact between the cells and the metal frame, thereby preventing high-voltage areas from forming between them. Since PID effects are often caused by high voltage areas, this isolation performance is crucial to prevent PID effects.
In addition, Mirror yellow film also has good light transmittance. Although it appears yellow, it does not significantly reduce the photoelectric conversion efficiency of the photovoltaic module. On the contrary, its light transmittance ensures that sunlight can penetrate the film, be absorbed by the cells, and converted into electrical energy. This efficient energy conversion is crucial to improving the power generation efficiency of photovoltaic power plants.
During the manufacturing process, Mirror yellow film also shows its unique advantages. It has low shrinkage and high stability, which means that the size and shape of the film remain relatively stable during the lamination process. This stability ensures the quality of PV modules during manufacturing and avoids the risk of PID due to dimensional changes.
Finally, Mirror yellow film also requires special attention during storage and transportation. It should be stored in a dry, cool environment away from direct sunlight and high temperatures. At the same time, heavy pressure and collisions also need to be avoided during transportation to ensure that the integrity and performance of the film are not affected.
To sum up, Mirror yellow film effectively protects photovoltaic modules from PID risks through its high-quality material selection, superior isolation performance, good light transmittance, high stability and correct storage and transportation methods. This kind of film has broad application prospects in the photovoltaic industry and is of great significance for improving the power generation efficiency and long-term stability of photovoltaic power stations.
