The solar cell module further includes a light redirecting film which comprises a concave-convex reflective structure, and the concave-convex reflective structure includes an array of abutting triangular prisms. An angle between an orthographic projection of an orientation direction of the array of abutting triangular prisms on the back sheet and an orthographic projection of the solar cell strings on the back sheet is in a range of 45-80 degrees. A vertical distance between a plane where apexes of the concave-convex reflective structure are located and a plane where the solar cells are located is in a range of 200 - 600 μm. The solar cell module can achieve high power generation efficiency while satisfying safety.

摘要： An adhesive composition comprises a resin base material, a peroxide crosslinking agent, a non-peroxide crosslinking agent, a coupling agent, an ultraviolet absorber, and an ultraviolet stabilizer, wherein the adhesive composition undergoes an exothermic reaction at a temperature of 95°C or more and has an exothermic amount of 2-40 J/g. The invention further provides a light redirecting film which comprises a reactive adhesive layer comprising the adhesive composition. Furthermore, the invention further provides a solar cell module comprising the light redirecting film. When the adhesive composition according to the present invention is used as an adhesive layer for adhering a light redirecting film to a back sheet during the assembly of a solar cell module, the formation of bulges in the adhesive layer during high moisture-heat aging may be avoided while maintaining the high adhesion of the adhesive layer, and the relative positional drift of the light redirecting film during the high temperature laminating process may be greatly reduced.
