Method of quantitative analysis of fluorescent light

摘要

A fluorescent dye is a wavelength shifting material that absorbs light of a broadband spectrum of light such as sunlight and artificial illumination, and fluoresces by converting it into light of specific wavelengths. In this study, the authors have developed, instead of using the ray - tracing method, the computer program named "method of quantitative analysis of fluorescent light" which calculates output energy of fluorescent material in a flat plate shape. We tested the program whether it was proper to analyze the flat plate type fluorescent material by photodiode(S1087). It is confirmed that the calculated values by this program agree with the measured ones for the flat plate sample from 1 to 5mm in thickness and red in color. And then we also research on improving the efficiency of CdS/CdTe solar cell whose spectrum response had high sensitivity in long wavelength(500 - 900nm) by using this program.
