Performance Enhancement of Luminescent Solar Concentrator by using Mixing Fluorescent Colors and Nanoparticles

Abstract

Liquid zinc acetate nanoparticles were added to a fluorescent organic dye (fluorescein sodium) to prepare three concentrations (2 × 10^-5, 7×10^-5, 1×10^-4) moI/L, and the absorbance of the dye was measured before and after adding Liquid nanomaterial by using two devices (SCINCO Mega-2100 UV/visible Spectrophotometer.) as well as measuring the flux of the dye before and after adding zinc acetate nanoparticles using the (Spectrofluorometer F96 PRO). The Stoke displacement (Δη), the radiative age (τfm), the fluorescence lifetime (τf), and the quantitative efficiency (Qfm) were calculated. Absorption and fluorescence curves were drawn using the Excel program. The MATLAB program was also used to measure the area under the absorption and fluorescence spectra curves. It was found that the fluorescence intensity of fluorescein sodium dye has increased compared to the intensity of fluorescence before adding the nanomaterial and thus increasing the quantitative efficiency, which in turn helps in improving the performance of the photovoltaic concentrator, resulting in an improvement in the efficiency of the solar cell.
