| Abstract: 8-Hydroxyquinoline(HQ) is a monoprotic bidentate chelating agent, which forms a fluorescent complex with AlCl3 in the ground and the excited states. The formation constants are determined from the least squares fitting of Benesi-Hildebrand and Hill plots. 8-hydroxyquinoline and 8-hydroxyquinoline aluminum salt (AlHQ3)show photostabilityin the presence of suspended TiO2 (Degaussa P25). The photostability of the surface complexes (8-HQ-TiO2) and (AlHQ3-TiO2) has been examined in the presence of (I-/I2) electrolyte solution showing a significant changes in the absorption and the fluorescence spectra of AlHQ3 and the rate of the reaction is determined. The photostability results of 8-Hydroxyquinoline favor its exploitation as a sensitizer in dyesensitized solar cell (DSSC). Light into electricity conversion efficiency is calculated from the current -voltage (I-V) curve for 8-HQ sensitized solar cell.Although 8-HQ reveals an appreciatedphotostability, it is not an efficient dye for light to electricity conversion due to its limited light absorption range (290-340nm). | ||||
