The invention discloses a black infrared reflection type photovoltaic EVA (Ethylene Vinyl Acetate) adhesive film. The photovoltaic EVA adhesive film comprises EVA resin as well as the following raw materials counted by the mass of the EVA resin: 0.1-2% of a cross-linking agent, 0.1-2% of an assistant crosslinker and 0.05-0.5% of an infrared reflection pigment. According to the photovoltaic EVA adhesive film, the infrared reflection pigment is added in the EVA resin, is black and has high infrared reflectivity, so that the prepared EVA adhesive film has good infrared reflection performance; by packaging a photovoltaic assembly by virtue of the photovoltaic EVA adhesive film, the power loss and temperature rise of the packaging assembly can be effectively reduced.
