Pseudohalogens for Dye-Sensitized TiO2 Photoelectrochemical Cells
Abstract
In this paper, we report on the preparation and characterization of two pseudohalogen redox couples for dye-sensitized TiO 2 photoelectrochemical cells. The equilibrium potentials of the (SeCN) 2 /SeCN - and (SCN) 2 /SCN - couples are respectively 0.19 and 0.43 V more positive than for the I 3 - /I - couple, providing the opportunity to determine the influence of the redox potential on the open circuit photovoltage. With the sensitizer cis -Ru(dcb) 2 (NCS) 2 (N3), the incident photon-to-current conversion efficiency was 20% for the (SeCN) 2 /SeCN - couple and 4% for the (SCN) 2 /SCN - couple. Transient absorbance measurements showed that the quantum yield for electron injection is independent of the pseudohalogen redox couple and that the regeneration rates of the dye decrease in the order I - > SeCN - > SCN - . The effects of the redox potential on open circuit photovoltage were determined by independent measurement of the dependence of the sensitized TiO 2 working electrode and the platinum counter electrode potentials on the cell voltage.

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.
