The invention discloses an EVA packaging adhesive film for resisting potential-induced degradation (PID) of a photovoltaic module. The adhesive film is mainly used in the field of photovoltaic module packaging. The EVA packaging adhesive film for resisting potential-induced degradation of a photovoltaic module is prepared from the following raw materials: by weight, 100 parts of ethene-vinyl acetate copolymer, 0.2-1.5 parts of an initiator, 0.1-0.5 part of an anti-oxidant, 0.1-0.5 part of an ultraviolet absorber, 0.1-0.5 part of a light stabilizer, 0.1-1.0 part of a tackifier, and 0.1-1 part of a metal ion capture agent. According to the EVA packaging adhesive film for resisting potential-induced degradation of the photovoltaic module, by adding the metal ion capture agent into a common EVA packaging adhesive film, mobility of metal ions is reduced, and the anti-PID characteristic of the photovoltaic module is raised from the source. In addition, the method is simple and the cost is low, so as to help further popularization of a photovoltaic product.
