Abstract

The invention relates to an EVA (ethylene vinyl-acetate copolymer) adhesive film capable of simplifying a packaging structure of a solar battery. The EVA adhesive film is prepared from the following raw materials in parts by weight: 100 parts of EVA, 0.5-1.0 part of crosslinking agent, 0.5-5 parts of compatilizer, 0.5-1 part of antioxidant, 0.05-1 part of light stabilizer, 1-10 parts of titanium dioxide and 0.5-1.5 parts of tackifier. The EVA adhesive film is prepared by the following steps: mixing the EVA with other assistants, carrying out melt extrusion, casting to form a film, and finallyrolling to obtain the finished product. The adhesive film provided by the invention is mainly used between a solar battery component and a back panel; and unlike the common EVA packaging adhesive film and back panel material, the adhesive film provided by the invention can simplify the packaging structure of the solar battery, can effectively lower the cost of the solar battery pack, and is beneficial to the further popularization of the solar battery.

Description

technical field

[0001] The invention relates to an EVA adhesive film which can simplify the packaging structure of solar cells. The adhesive film is mainly used between solar cell elements and back plate materials, and is used in the field of solar cell component packaging. Background technique

[0002] Solar energy is a green, non-polluting and inexhaustible energy source. At present, solar panels are mainly used to convert it into electrical energy, and then use it for other purposes, such as street lamps, water heaters, electric vehicles, etc. Since solar cells are generally used outdoors and the environment is relatively harsh, they need to be protected. They are usually packaged with a glass plate (front plate), packaging film and back plate. The glass plate (front plate) used is mainly low taconite tempered glass, which is located on the solar cell element and has high light transmittance and excellent weather resistance.

[0003] Among them, the function of the adhes...
