摘要： The present invention relates to an encapsulant film composition, an encapsulant film, and a solar cell module, comprising an ethylene/alpha-olefin copolymer. When an encapsulant film is manufactured by using the encapsulant film composition according to the present invention, the immersion time of the ethylene/alpha-olefin copolymer is reduced, and thus the encapsulant film production process can be more economical. In addition, the encapsulant film composition prepared by using the present invention exhibits an excellent degree of cross-linking.
