Encapsulation Adhesive Film and a Photovoltaic Module

Abstract

Provided in the present disclosure are an encapsulation adhesive film and a photovoltaic module. The encapsulation adhesive film includes an infrared high-transmittance adhesive film layer, and an infrared high-reflection adhesive film layer, which is stacked on the infrared high-transmittance adhesive film layer. The light transmittance of the infrared high-transmittance adhesive film layer for light within a wavelength range of 700-1100 nm is greater than 55%; the light transmittance of the infrared high-transmittance adhesive film layer for light within a wavelength range of 400-700 nm is less than 2%; and the reflectivity of the infrared high-reflection adhesive film layer for the light within the wavelength range of 700-1100 nm is greater than 75%. By using the encapsulation adhesive film as an encapsulation adhesive film on a back side of a cell piece, black exterior appearance of the photovoltaic module can be realized so as to reduce light pollution.
