Spectral Sensitization of TiO 2 Nanocrystalline Electrodes with Aggregated Cyanine Dyes
Abstract
New chromophores were explored for use in dye-sensitized solar cells. The attachment of various di-carboxylated cyanine dyes to nanocrystalline TiO 2 was examined spectroscopically and through their performance in a sensitized solar cell. It was found that aggregated forms of these cyanine dyes sensitized with an efficiency equal to that of the monomer form and that combinations of cyanine dyes could be used to sensitize solar cells over the entire visible spectrum. With the high extinction coefficients of the organic dyes, short circuit photocurrents for these cyanine-sensitized systems was maximized at a 4 μm thickness of the nanocrystalline TiO 2 . Short circuit photocurrents for these 4 μm solar cells were found to exceed that of ruthenium coordination complexes.

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.
