Document Type and Number:
Japanese Patent JP6777246
Kind Code:
B2
Abstract:
A light wavelength conversion member in which silicon nanoparticles are dispersed having a higher photoluminescence intensity, a method of production of the same, a photovoltaic module, and a photovoltaic cell, in particular, a light wavelength conversion member comprised of a substrate on one surface of which is formed a silicon oxide film in which silicon nanoparticles of a size of 1 nm to 10 nm are dispersed, the silicon oxide film, when the silicon oxide film is measured by the electron spin resonance method, having a spin density in the range of g=1.998±0.001 of 1×1016/cm3 or less and a spin density in the range of g=2.003±0.001 of 3×1016/cm3 or less and having a photoluminescence quantum yield with respect to incident light of a wavelength of 300 nm to 500 nm of 15% or more.
