Expermential Study of the Performance of Fluorescence Collector

Abstract

The luminescent concentrator which used consisting of organic fluorescence dyessuch as Rhodamine 6G doped in article Polyvinyl alcohol (PVA) to configure aspecific membrane thickness, and then put these films on the glass plate solar collectormodel with energy halogen Lamp (1000 Watt) as a source of light to represent offluorescence collector.Examining the effect of these pigments on the efficiency of the solar collector as afunction of the temperature difference between the water inside and outside of the solarcollector. Where the increasing in the amount of the difference between thetemperature refers to increasing the efficiency of the performance of solar collector.Results showed that the efficient performance of the solar collector increases with theincrease in the intensity of incident light with existence the luminescent concentrator,where the rising water temperature of (24 K) compared with (20 K) when there is notexistence the luminescent concentrator when the intensity of radiation falling (1500W/m2) and increasing efficiency of solar collector to 20% .
