This invention provides an organic rare earth metal complex, which emits fluorescence with a wavelength in the range of 550 to 900 nm, particularly a fluorescent resin composition comprising an ethylene-vinyl acetate copolymer containing 0.01 to 10% by mass of an organic rare earth metal complex represented by general formula
wherein R represents an aliphatic or aromatic hydrocarbon group; Ln represents a rare earth metal; A represents group -CH=CH-; and n is 0 or 1. There are also provided a solar battery module using the fluorescent resin composition as a sealing material between a front cover and a crystalline silicon cell, and a solar battery with high conversion efficiency.
