Effect of Impurity Particles on the Spectral Properties of Hibiscus sabdariffa Organic Dye used in Solar Cells Industry
In this work, the spectral properties of the Hibiscus sabdariffa organic dye solved in different solvents were studied by introducing the effect of dye concentration on its absorbance and transmission spectra within the range 400-800nm. As well, the effect of adding impurity particles of a semicondu...

| description | In this work, the spectral properties of the Hibiscus sabdariffa organic dye solved in different solvents were studied by introducing the effect of dye concentration on its absorbance and transmission spectra within the range 400-800nm. As well, the effect of adding impurity particles of a semiconductor to the dye solution on these properties was introduced. Results showed that the spectral properties of the dye depend substantially on the type of the solvent, which has to be chosen carefully to achieve the optimum properties of this dye to be used as a sunlight sensing organic medium in dye-sensitized solar cells. Also, the results showed that the spectral properties of this dye are noticeably affected by the presence of impurity particles of a semiconductor when the suitable solvent is used. These particles act as scattering centers through the solution to the electromagnetic radiation in the visible region and hence the intensities of the absorbed and transmitted components of the radiation are decreased |
