EVA film belongs to a kind of photovoltaic encapsulation film.
Common PV single-glass module, its structure is Glass/encapsulation film/cell/encapsulation film/backsheet.
Photovoltaic encapsulation film
It is widely used in the internal encapsulation material of photovoltaic modules. At present, there are two main types in the market, namely EVA film and POE film. It is mainly used for laminating on the surface of the battery, which can resist the influence and damage of the external environment on the performance of the battery cell, and play a protective role for the battery cell.POE is the second largest PV encapsulation material after EVA, and has stronger barrier characteristics, which can be applied to crystalline silicon cells and thin film battery encapsulation.
Characteristics of EVA encapsulation film
※ Excellent weather resistance: high temperature, high humidity, strong UV resistance
※ Good adhesion: good adhesion with various materials such as glass, metal, polymer backsheet, etc., and can be maintained for a long time.
※Excellent light transmission
※ Excellent maneuverability: easier to stack together, short lamination time, high efficiency.
Characteristics of POE encapsulation film
※ Lower water vapor transmission rate
※ Longer PID resistance
※Excellent light transmission
※Good adhesion: good adhesion to various materials such as glass, metal, polymer backsheet, etc., and can be maintained for a long time.
※Excellent weather resistance: high temperature, high humidity, strong UV resistance, anti-aging.
