EVA photovoltaic encapsulation film For Industry plays a vital role in the lamination process of photovoltaic modules. It provides a number of key properties to ensure the high efficiency, stability and long-term operation of photovoltaic modules. EVA encapsulation film is designed with a special formula to give it excellent adhesion properties. During the lamination process, the EVA film can fit tightly between the front and back of the solar cell, the glass cover and the back plate to form a continuous, gap-free encapsulation layer. This tight adhesion not only prevents the intrusion of harmful substances such as moisture and dust, but also enhances the overall structural strength of the module and improves the weather resistance and durability of the photovoltaic module.
EVA encapsulation film has extremely high light transmittance in the molten state, which means that it can maximize the penetration of sunlight and irradiate the solar cell, thereby improving the photoelectric conversion efficiency of the photovoltaic module. In addition, EVA film can also reduce the reflection and scattering of light, further improving the utilization rate of light energy and ensuring the optimal power generation performance of photovoltaic modules under lighting conditions.
During the lamination and subsequent curing process, the EVA encapsulation film exhibits an extremely low shrinkage rate, which ensures a high degree of dimensional consistency of the photovoltaic modules. The low shrinkage rate helps to avoid deformation or cracking of the modules due to thermal expansion and contraction during long-term use, thereby ensuring the mechanical stability and power generation efficiency of the photovoltaic modules.
The EVA encapsulation film has good fluidity and plasticity during the lamination process, which enables it to adapt to various complex lamination processes and equipment requirements. Whether it is manual lamination or automated production lines, the EVA film can perform well and ensure the smooth progress of the lamination process. At the same time, the curing speed of the EVA film is moderate, which is easy to operate and control, and improves production efficiency.
The EVA encapsulation film is specially formulated and has excellent weather resistance. It can resist the erosion of harsh environmental conditions such as high temperature, high humidity, and ultraviolet rays, ensuring the stable operation of photovoltaic modules under extreme weather conditions. In addition, the EVA film also has good anti-aging properties, and can maintain the stability of its physical and chemical properties even during long-term use, extending the service life of photovoltaic modules.
The key properties of EVA photovoltaic encapsulation film For Industry during the lamination process, such as excellent adhesion performance, high light transmittance, low shrinkage, good operability and process adaptability, as well as excellent weather resistance and long-term stability, together constitute an important guarantee for the efficient, stable and long-term operation of photovoltaic modules.
