Cis-bis(isothiocyanato)-bis(2,2 '-bipyridyl-4,4 ' dicarboxylato)-Ru(II) (N719) dark-reactivity when bound to fluorine-doped tin oxide (FTO) or titanium dioxide (TiO2) surfaces

Journal article

The solar cell sensitizer cis-bis(isothiocyanato)-bis(2,2′-bipyridyl-4,4′dicarboxylato)-ruthenium(II) (N719) is adsorbed and investigated at two electrode surfaces: (i) at a bare fluorine-doped tin oxide (FTO) and (ii) at a nano-particulate anatase (TiO2) film in contact with FTO. N719 is adsorbed from acetonitrile onto FTO surfaces giving poor quality partial or multi-layer coverage commencing at 10-7 M concentration. In contrast, from 50% acetonitrile 50% tBuOH solution of N719 Langmuirian ...
