An Alternative Efficient Redox Couple for the Dye‐Sensitized Solar Cell System
Open accessAbstract
A series of new cobalt complexes [Co(LLL)2 X 2] were synthesized and evaluated as redox mediators for dye‐sensitized nanocrystalline TiO 2 solar cells. The structure of the ligand and the nature of the counterions were found to influence the photovoltaic performance. The one‐electron‐transfer redox mediator [Co(dbbip)2](ClO 4)2 (dbbip = 2,6‐bis(1′‐butylbenzimidazol‐2′‐yl)pyridine) performed best among the compounds investigated. Photovoltaic cells incorporating this redox mediator yielded incident photon‐to‐current conversion efficiencies (IPCE) of up to 80 %. The overall yield of light‐to‐electric power conversion reached 8 % under simulated AM1.5 sunlight at 100 W m−2 intensity and more than 4 % at 1000 W m−2. Photoelectrodes coated with a 2 μm thick nanoporous layer and a 4 μm thick light‐scattering layer, sensitized with a hydrophobic ruthenium dye, gave the best results.

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.
