Wavelength conversion-type photovoltaic cell sealing material and photovoltaic cell module using the same |
摘要 |
The present invention provides a wavelength conversion-type photovoltaic cell sealing material, the sealing material including at least one light emitting layer containing a group of spherical phosphors, the group of spherical phosphors having a ratio of a median value D50 of the group of spherical phosphors to a total thickness t of the light emitting layer of from 0.1 to 1.0, where the median value D50 is a median value of a volume particle size distribution of the group of spherical phosphors, and an integrated value N of a number particle size distribution from D25 to D75 of the group of spherical phosphors being 5% or more, when D25 is a particle size value at 25% of an integrated value of the volume particle size distribution of the group of spherical phosphors and D75 is a particle size value at 75% of the integrated value of the volume particle size distribution of the group of spherical phosphors; and a photovoltaic cell module including the sealing material. |
