METHODS FOR CONTROLLING OPTICAL PROPERTY OF WAVELENGTH CONVERSION SHEET AND FOR PRODUCING WAVELENGTH CONVERSION SHEET, WAVELENGTH CONVERSION SHEET FOR CADMIUM TELLURIDE SOLAR CELL, AND CADMIUM TELLURIDE SOLAR CELL

摘要

The present invention provides a method for controlling an optical property of a wavelength conversion sheet. The method is a method for controlling an optical property of a wavelength conversion sheet that contains a transparent resin and a phosphor and achieves wavelength conversion by absorbing light in a specific wavelength range other than a target wavelength range and emitting light in a target wavelength range, wherein the phosphor contains a phosphor having a perylene skeleton, and a stokes shift of the wavelength conversion sheet is controlled by adjusting a concentration of the phosphor having a perylene skeleton to the transparent resin in a range of 0.5% to 3.5% by weight.
