Abstract

The invention discloses a packaging material, a packaging adhesive film, a manufacturing method of the packaging adhesive film and a photovoltaic module, relates to the technical field of photovoltaics, and aims to ensure that the packaging material not only has good PID (Potential Induced Degradation) resistance, but also has relatively low production cost. The packaging material is used for packaging a photovoltaic module. The packaging material comprises a polyethylene-polyvinyl acetate copolymer, a nanoscale inorganic filler, a cross-linking agent component, a coupling agent and an auxiliary component, and the nanoscale inorganic filler is a nanoscale inorganic oxide capable of carrying negative electricity. The packaging adhesive film comprises the packaging material provided by the technical scheme. The packaging material provided by the invention is used for the photovoltaic module.

Description

technical field [0001] The invention relates to the field of photovoltaic technology, in particular to an encapsulation material, an encapsulation adhesive film, a manufacturing method thereof, and a photovoltaic module. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA for short) is a thermosetting adhesive film that can be placed between laminated glass. Because EVA has significant advantages in adhesion, durability, optical properties, etc., it is more and more widely used in current components and various optical products. [0003] In the related technology, the solar cells can be encapsulated with high transparency, excellent anti-ultraviolet and aging resistance, good adhesion, and elastic EVA film, and can be combined with the upper protective material (such as glass) and the lower protective material (such as backsheet or glass) bonded together to form a photovoltaic module. In practical applications, the double-glass module uses the encapsulation...
