In order to improve the Voc and Jsc, we synthesized light Nb-doped anatase TiO2 nanoparticles and employed in organic dye-sensitized solar cells with hole-conducting coadsorbents. Nb-doped TiO2 is possible to increase the charge transport ability by the formation of intra-band state and the charge injection improvement thus increasing the Jsc. The hole-conducting coadsorbents 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. |
