Influence of the Nature of the Absorption Band on the Potential Performance of High Molar Extinction Coefficient Ruthenium(II) Polypyridinic Complexes As Dyes for Sensitized Solar Cells
(American Chemical Society, 2011-05-31)
When tested in solar cells, ruthenium polypyridinic
dyes with extended π systems show an enhanced lightharvesting
capacity that is not necessarily reflected by a high
(collected electrons)/(absorbed photons) ratio. ...
