Improve solar cell energy conversion efficiency by using illuminescent dyes concentrators
Abstract
AuramineO is fluorined organic and sensitive for light,has been chosen in this workdissolved in ethanol liquid. The Ethanol did not effected onAuramineO absorption because the absorption of Ethanol drop and approaches to zero in the visible spectrum region .After studying the spectroscopic properties of AuramineO dye ,it showed that it have wide range of absorptionspectra and high fluoridation.So the relative intensity of both absorption and fluorescespectra were increasedbyincreasing concentrationto a certain extent andthus compatible with Beer- Lambert law. Accordingly we could determine the highest absorption and fluorescence of each concentration and calculated molar absorptioncoefficientes ,quantum efficiency , radiated lifetime, fluorescence lifetime and stokes shift . These panelsofAuramineO dye were used as concentrators for solar cell and all their panels are infallible improving and raies the efficiency of solar cell at ratio spotty.Measuresof the thickness for the panelsshowed they effect on the efficiency solar cell that the thicknessof panels if increase thesolar cell efficiency decrease, therefore it is preferred using little thickness.
