摘要

The efficiency of electron injection from excited N3 dye (cis-bis-(4,4'-dicarboxy-2,2'-bipyridine) dithiocyanato ruthenium(II), Ru(dcbpy)_2 (NCS)_2), into various nanocrystalline semiconductor (ZrO_2, TiO_2, ZnO, Nb_2O_5, SnO2, In2O3) films was studied by transient absorption spectroscopy. For TiO_2, ZnO, Nb_2O_5, SnO_2, or In_2O_3 films, injection efficiencies were found to be very high; for ZrO_2 film, the efficiency was very low. These findings indicate that electron injection occurs efficiently if the LUMO level of N_3 dye is located sufficiently far above the bottom of the conduction band of the semiconductor film. On the basis of the results, we discuss the reason TiO_2 exhibits higher solar cell performance than other materials.
