Generally speaking, the encapsulation film needs to be light-transmitting, bondable, resistant to ultraviolet rays and high temperatures, low water-permeable, and have a high resistivity (reduce leakage current). With the increasing performance requirements of different component factories for photovoltaic encapsulation films, photovoltaic encapsulation films are gradually developing towards multi-layer structures.
