[0181]

[0182] Weigh 0.96 g (0.04 mol) of sodium hydroxide, and add 22.5 ml of dehydrated tetrahydrofuran under a nitrogen atmosphere. While vigorously stirring, a solution of 2.52 g (0.02 mol) of 2-acetylthiophene and 3.70 g (0.024 mol) of methyl 4-fluorobenzoate dissolved in 12.5 ml of dehydrated tetrahydrofuran was added dropwise over 1 hour. Thereafter, it was refluxed for 8 hours under a nitrogen stream. This was returned to room temperature (25 degreeC), 10.0 g of pure waters were added, and 5.0 ml of 3N hydrochloric acids were added further. The organic layer was separated and concentrated under reduced pressure. The concentrate was recrystallized to obtain 2.83 g (57% yield) of FTP.

Abstract

A spherical phosphor comprises a fluorescent substance having a maximum excitation wavelength of 400 nm or longer and a transparent material in which the fluorescent substance is contained, wherein an excitation spectrum intensity in a wavelength region of 340 to 380 nm inclusive is 50% or more of an excitation spectrum intensity at a maximum excitation wavelength of the spherical phosphor in the excitation spectrum of the spherical phosphor. A sealing material for wavelength-conversion-type solar batteries involves a light-transmissive resin composition layer comprising the spherical phosphor and a sealing resin.

Description

technical field [0001] The present invention relates to a spherical phosphor, a wavelength conversion type solar cell sealing material, a solar cell module and their manufacturing methods. Background technique [0002] Conventional crystalline silicon solar cell modules have the following configurations. The protective glass on the surface (also called cover glass) emphasizes impact resistance and uses tempered glass, in order to make it compatible with the sealing material (usually a resin mainly composed of ethylene-vinyl acetate copolymer, also called filler) The adhesiveness is good, and the concave-convex pattern formed by embossing is applied on one side. [0003] In addition, the concavo-convex pattern is formed inside, and the surface of the solar cell module is smooth. In addition, a sealing material and a back film for protecting and sealing the solar battery elements and tab lines are provided on the lower side of the protective glass. [0004] In general, ligh...
