We developed N-doped TiO2 photoanodes with various N-doped percentages and employed in organic dye-sensitized solar cells with hole-conducting coadsorbents in order to improve the Voc and Jsc in DSSCs. N-doped TiO2 photoanodes increased the charge transport ability, resulting in increasing the light-havesting performance in IPCE spectra. Moreover, N-doped TiO2 photoandes increased the electron lifetime, which can enhance the Voc. The hole-conducting coadsorbents have been incorporated in DSSCs to have multiple functions, that is, the prevention effect of π-π stacking of organic dye to enhance Voc by reducing the charge recombination and the cascade-typed hole hopping channel to enhance Voc and Jsc. |
