Photoelectrochemical Properties of a Porous Nb2O5 Electrode Sensitized by a Ruthenium Dye
Abstract
In studying the photoelectrochemical properties of TiO 2, Nb 2 O 5, ZnO, SnO 2, In 2 O 3, WO 3, Ta 2 O 5, and ZrO 2 porous semiconductor films sensitized by the ruthenium(II) cis -bis(thiocyanato)bis(2,2‘-bipyridyl-4,4‘-dicarboxylic acid) complex, it was found that the Nb 2 O 5 semiconductor cell had the next highest incident of monochromatic photon-to-current efficiency (IPCE = 18%) compared to the TiO 2 cell and showed the highest open-circuit photovoltage ( V oc ) among them. The V oc of the dye-sensitized cell was proved to be related to the flatband potential of the semiconductor electrode. The Ru dye adhered to the Nb 2 O 5 surface mainly through an ester-like linkage. It is speculated that electrons are transferred mainly through the conjugated orbitals of the ester linkage and semiconductor conduction band and that the TiO 2 and Nb 2 O 5 conduction bands consisting of d-orbitals are more advantageous than those of s-orbitals in attaining the desired IPCE. The IPCE of the Nb 2 O 5 cell was markedly improved by treating the Nb 2 O 5 electrode with Nb alkoxide, and the maximum IPCE was 32% at 548 nm. The overall solar-to-electric energy conversion efficiency was about 2% (AM-1.5, 100 mW/cm 2 ).

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
