摘要
It is an object to improve photoelectric conversion efficiency by use of a wavelength conversion film that is formed without dispersion of wavelength conversion substance and by using no rare earth compound. There is provided a composition for easily forming such a wavelength conversion film by spin-coating or the like. The present invention relates to a composition for forming a wavelength conversion film for a photovoltaic device, comprising a polymer or an oligomer in which a fluorescent moiety is incorporated, and a solvent. The fluorescent moiety may be incorporated in a main chain or a side chain of the polymer or the oligomer. The present invention also relates to a wavelength conversion film for a photovoltaic device that is formed from the composition for forming a wavelength conversion film.
