The invention provides a high-reflection photovoltaic module packaging adhesive film with a three-layer structure, which is characterized in that a transition layer, a structural reflection layer and a packaging layer are sequentially arranged from top to bottom, the upper surface of the structural reflection layer is provided with a plurality of parallel first prism structures and a plurality of parallel second prism structures, the first prism structures and the second prism structures are crossed to form a # -shaped arrangement, the lower surface of the structural reflection layer is provided with a plurality of concave hemispherical structures, and the lower surface of the packaging layer is provided with a plurality of protruding T-shaped structures. Its advantage does: the reflectivity is high, the PID resistance effect is better, the simplicity and the high efficiency are realized, the assembly production process flow is not increased, and the large-scale popularization and application are suitable. |
