The object of the present invention is to provide a light-emitting ethylene-based copolymer that does not cause problems of migration and bleeding of phosphors, has high processability, has ideal optical characteristics and good light stability, and is easy to handle in the kneading process, and A solar cell encapsulating material composition using the same. In addition, the present invention provides an encapsulating material layer for solar cells formed using the above-mentioned encapsulating material composition for solar cells, and a photovoltaic module having the same, the encapsulating material layer for solar cells does not cause the problem of migration and bleeding of phosphors, And has ideal optical properties and good photostability. The present invention provides a light-emitting vinyl copolymer comprising a fluorescent dye compound having an unsaturated bond as a monomer component. |
