Abstract
A wavelength-converting encapsulant composition is provided, which includes a first organic material capable of absorbing ultraviolet light and converting absorbed light to longer wavelength light; and a second organic material capable of absorbing light with a wavelength longer than that of the light absorbed by the first organic material and converting absorbed light to longer wavelength light, wherein the maximum emission wavelength λof the first organic material and the maximum excitation wavelength λof the second organic material satisfy the relationship of formula (1): λ−60≤λ(nm), and which has high durability, is advantageous in terms of cost and suitable for use on solar cells, and can improve the photoelectric conversion efficiency of solar cells by converting light in a wavelength region not contributable to power generation to light in another wavelength region contributable to power generation.
