We intend to use a synthetic mineral dye for use in the dye-sensitized solar cell. But this color is not soluble in any solvent. What method do you suggest for absorbing this dye on the titanium dioxide layer?
Natural dyes were used as a light harvesting pigments for Dye-sensitized solar cell. The effect of dye extracting solvents on the performance of solar energy conversion has been studied. Quasi-solid state electrolyte and PEDOT as a counter electrode has been used for DSSC assembly.
Dear Kambiz Hosseinpanahi , if your insoluble dye can be dispersed as a suspension in a volatile solvent, then it could be distributted in the voids of the TiO2 layer.
Probably you could try to mix together the TiO2 and the dye and then make a paste with them for depositing them on top of the electrode substrate, just using the same solvent you use for depositing the TiO2 alone.
Consider also possibilities to synthetize the dye right on the surface where you want it. This can be surface of TiO2 particles in suspension, or a ready porous layer of titanium dioxide. For the latter ALD (atomic layer deposition) technology probably might be used, proponents of it often say that ALD can be used to make any layers.
