Multi-dye coated electrodes for solid state TiO2|dye|p-semiconductor solar cells

Dyes and pigments absorb unique portion of visible light. Solvatochromic behavior and formation of monomers and aggregations are characteristics features of dyes. Several types of dyes and pigments have been employed to study sensitization process of TiO2|sensitizer|p-semiconductor type solar cells. An enhancement of efficiency of this type of solar cells could be expected by appropriate coupling of several dyes as a result of fully coverage of visible spectrum. A comparable study of multi dye systems was carried compare to that of mono dye systems.
