differences in application of eva film photovoltaic modules

the eva film used in the production of photovoltaic modules is a transparent colloid with good light transmittance and aging resistance. it encapsulates the crystalline silicon wafer set with an "upper cover and lower pad" and is bonded with the upper protective material glass and the lower protective material tpt (polyfluoroethylene composite film) using vacuum lamination technology to form a crystalline silicon component. long...

basic principles of using eva dimming film

basic principles for using eva dimming film: 1. when the dimming film is powered off, the polymer liquid crystal materials in it are arranged in disorder, making it impossible for light to penetrate the film. the effect seen at this time is a milky white opaque state. 2. when the dimming film is energized, the polymer liquid crystal material in the middle of the film is arranged in an orderly manner under the action of the electric field, which can make...
