The invention provides an adhesive film, a preparation method thereof and a photovoltaic module. The preparation method comprises the following steps: mixing the first matrix resin, the first initiator and the light diffusant to obtain light diffusion layer ingredients; mixing the second matrix resin, the second initiator and the long afterglow material to obtain a long afterglow layer ingredient; mixing the third matrix resin, the third initiator and the white filler to obtain a white filler layer ingredient; and carrying out melt co-extrusion on the light diffusion layer ingredient, the long afterglow layer ingredient and the white filler layer ingredient to obtain the adhesive film. The adhesive film with the structure prepared by the method has higher luminescence or light transmittance, and the photoelectric conversion efficiency of the photovoltaic module can be greatly improved by applying the adhesive film to the preparation of the photovoltaic module, so that the cost of a power station is reduced, and the reliability of a product is improved. |
