In this work, we studied the absorption and fluorescencespectrum of the (4,4'-((1E,1'E)-[1,1'-biphenyl]-4,4'-diylbis(diazene-2,1-diyl))bis(5-methyl-2,4-dihydro-3H-pyrazol-3-one)(Bpbpy)dye. Five differentconcentrations were prepared at room temperature after dissolving the dye into Ethanol with 99.99% purity.
The absorption and fluorescence spectra were measuredby usingUv-Vis Spectrophotometerand Spectrofluorometer with a wavelength range of (200 - 900) nm, theyshowed that the peaks of intensity of the absorption and fluorescence were increased with increasingthe concentration. At the same time, there is a shifting in the spectra peaks to high waves length (red shift), the fill factor (FF)was also calculatedfor all solutions.
The efficiency of solar cell was calculated before and after using the luminescent solar concentrator (LSC),the highest efficiency((ηwas(15.86) for the solar cellwith concentration(1×10-4) mol/L.
