Title:
WAVELENGTH CONVERSION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2016/194193
Kind Code:
A1
Abstract:
Provided is a wavelength conversion material for solar batteries which can efficiently convert light of wavelengths of 500 nm or less, at which the sensitivity of a solar battery is relatively low, to light of 500 nm or more, at which the solar battery sensitivity is high.
The wavelength conversion material for solar batteries includes a material (A) having an absorption wavelength peak of less than 500 nm, and a material (B) having a light emission wavelength peak of 500 nm or more, wherein the material (B) is present in order to make it possible for light to be emitted as a result of the transfer of energy from the material (A).
