The invention discloses a black EVA (ethylene vinyl acetate copolymer) adhesive film and a double-glazed photovoltaic module. The black EVA adhesive film comprises components in percentage by weight as follows: 70%-95% of ethylene vinyl acetate copolymer, 1%-5% of black pigment, 2%-15% of heat conducting filler and the balance of additives. By comparison with the prior art, the heat conducting filler is added to the black EVA adhesive film, the heat conducting performance of the EVA adhesive film can be effectively improved, the nominal operating temperature of the double-glazed photovoltaic module is reduced, and generation power can be provided for the double-glazed photovoltaic module at the nominal operating temperature; besides, the double-glazed photovoltaic module packaged by the black EVA adhesive film is attractive, elegant and capable of being widely applied to photovoltaic projects of buildings, roofs, sheds and the like. |
