Apart from the molecular structure, high absorption coefficient,we know that absorption is depending on the material band gap. From the band gap we easily determine the absorption wavelength range. Is there any significance about dye color in DSSC?
For selecting dye in fabrication of dye sensitized solar cell satisfy the following requirment
1) Dye should contain specific anchoring groups for adsorption on metal oxide surface
2) Dye should Absorb light in visible and near IR region
3)The LUMO of the dye must be more negative (higher)
than the CB of the semiconductor.
4)The HOMO of the dye should be more positive than the
redox potential of the electrolyte
5)The dye should form monolayer on the surface of photoanode
6)The dye should be photosensitive means it will absorb the light and excite the electron
