A kind of eva encapsulation adhesive film that improves the conversion power of solar modules

Abstract

The invention discloses an EVA packaging glue film with an effect of improving solar assembly transition power. The EVA packaging glue film comprises a transparent front glue film and a white back glue film. The front glue film is prepared from 0.05-5% by mass of a cross-linking agent, 0.05-5% by mass an assistant cross-linking agent, 0.05-3% by mass of a coupling agent, 0.05-2% by mass of a hydrophobic agent, 0.02-1.5 parts by mass of a light stabilizing agent, 0.02-1.0% by mass of an antacid, 0.02-1.0% by mass of a UV transition agent and the balance EVA resin. The EVA packaging glue film has a low cost, high performances and high transition power, has lasting resistance to damp and hot, UV, PID and snail cracks in a photovoltaic system and satisfies photovoltaic assembly market requirements now and forever.

Description

technical field

[0001] The invention relates to the technical field of production of solar photovoltaic components, in particular to an EVA encapsulation adhesive film for improving the conversion power of solar components. Background technique

[0002] Since my country launched the "Photovoltaic Leader" program in 2015, high-efficiency photovoltaic products have become the consensus of the industry and the development direction of the industry.

[0003] Stimulated by the "Top Runner" plan, in the next 3-5 years, the power of modules will increase faster, and the competition among enterprises will become a healthy competition with conversion efficiency as the core. Improving the conversion efficiency and reducing the cost of electricity is the key to the further development of photovoltaics.

[0004] The "Top Runner" plan promotes the improvement of the overall level of the industry from the aspects of manufacturing level, application level, standards and testing. The produ...
