SPHERICAL PHOSPHOR, SEALING MATERIAL FOR WAVELENGTH CONVERSION SOLAR BATTERY, SOLAR BATTERY MODULE AND METHOD FOR PRODUCING SAME

摘要

PROBLEM TO BE SOLVED: To provide a spherical phosphor which increases the efficiency for light utilization in a solar battery module, a sealing material for wavelength conversion solar battery containing the same, a solar battery module and a method for producing these.

SOLUTION: In the spherical phosphor including a fluorescent substance and a transparent material, the transparent material is prepared by suspension polymerization of a composition containing a vinyl compound to form a spherical form. Further, the composition containing a vinyl compound contains a di- or higher functional vinyl compound. The sealing material for wavelength conversion solar battery includes a light permeable resin composition layer containing the spherical phosphor and a sealing resin.
