▎ 摘　　要

NOVELTY - Encapsulation adhesive film comprises first adhesive film substrate (10) and a multiple organic high refractive index portions (20). The organic high refractive index portions are arranged at intervals on one surface of the first adhesive film substrate. The organic high refractive index portion is arranged in one-to-one correspondence with the encapsulated solar cell sheet, and the refractive index of the first adhesive film substrate is 1.45-1.50. The refractive index of the organic high refractive index portion is 1.49-1.8. The refractive index of the organic high refractive index portion is higher than the refractive index of the first adhesive film substrate. USE - Encapsulation adhesive film. ADVANTAGE - The organic high refractive index portion of the encapsulating adhesive film of the present application is arranged on the surface of the first adhesive film substrate, the structure is more stable and avoids the problem that the refractive index cannot be effectively increased due to agglomeration of additives. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a photovoltaic module, which includes a glass cover plate, a front layer encapsulation film, a solar cell unit, a back layer encapsulation film, and a back layer cover plate. The front-layer encapsulating adhesive film and/or the back-layer encapsulating adhesive film is the encapsulating adhesive film. The organic high refractive index portion is arranged in one-to-one correspondence with the solar cells in the solar cell unit. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of encapsulation adhesive film. Adhesive film substrate (10) Organic high refractive index portions (20)
