Abstract
The modification of non-metallic elements N and S to nanocrystalline TiO2 anode results in the energy gap is reduced to 2.63 eV and a strong redshift to the visible region occurred in the UVvisible spectrum. Poly (3-decylthiophene) (P3DT) is synthesized. Ultravioletvisible spectra (UVvis) shows that the light absorption of P3DT (Poly (3-decylthiophene)) and N719 (RuL2(NCS)2:2TBA (L=2,2′-bipyridyl-4, 4′-dicarboxylic acid)) are complementary to cover the entire visible region. Solar cell based on NS/TiO2 is co-sensitized by P3DT and N719. The photoelectric conversion efficiency of co-sensitized solar cell increases 56.8% comparing with the single dye-sensitized solar cell.
