Abstract:

The paper introduced the reasons, methods, and research results of modification for ethylene vinyl acetate copolymer (EVA) as an adhesive material for solar cell modules in terms of tensile strength, flame retardancy, UV aging resistance, and adhesion. In view of some defects of EVA materials, the research progress and development direction in new adhesive materials such as polyurethane and polyvinylbutyral were reviewed. Finally, the production technology of co?extruded solar backplane was briefly introduced.

Key words: solar backplane, ethylene vinyl?acetate copolymer, polyurethane, co?extrusion technology
