Embodiment 1
[0033] The thickness of the EVA adhesive film is 0.8mm, according to the weight fraction, including the raw materials of the following weight fraction: 100 parts of EVA resin, 0.5 part of plasticizer, 0.1 part of photoelectric conversion rate enhancer, 1 part of anti-aging agent, 1.5 parts of barrier agent, 1 part of dispersant, 1 part of coupling agent, 1 part of crosslinking agent.
[0034] The content of vinyl acetate (VA) in the EVA film is 32%, and the plasticizer is composed of spiropyran and phthalate plasticizer at a mass ratio of 1:4. The plasticizer is composed of butyl benzyl phthalate (BBP) and diethyl phthalate (DMP) in a mass ratio of 3:1. The photoelectric conversion rate enhancer is a bonded macromolecular rare earth complex, and the bonded macromolecular rare earth complex is 6-(acryloyloxy)naphthalene-2-carboxylic acid-europium (p-NJS-Eu). The anti-aging agent is composed of light stabilizer and antioxidant according to the mass ratio of 1:1; the light stabi...
