摘要： The present invention relates to: a composition for an encapsulation film, comprising an ethylene-α-olefin copolymer; an encapsulation film; and a solar cell module. When an encapsulation film is manufactured using the composition for an encapsulation film, according to the present invention, the dipping time of the ethylene-α-olefin copolymer is reduced, and thus the economic feasibility of producing an encapsulation film can be improved. In addition, the composition for an encapsulation film, prepared using the present invention, exhibits an excellent degree of crosslinking.
