Cation-dependent charge recombination to organic mediators in dye-sensitized solar cells

BN DiMarco, RM O'Donnell… - The Journal of Physical …, 2015 - ACS Publications
Mesoporous TiO2 thin films sensitized to visible light with [Ru (dtb) 2 (dcb)] 2+, where dtb is
4, 4′-((CH3) 3C) 2-2, 2′-bipyridine and dcb is 4, 4′-(CO2H) 2-2, 2′-bipyridine,
abbreviated TiO2| Ru, were investigated in acetonitrile electrolytes that contained 0.1 M
Na+, Li+, Mg2+, or Ca2+ perchlorate solutions with the electron donor tri p-tolylamine
(TPTA) or phenothiazine (PTZ). Pulsed 532 nm light excitation of TiO2| Ru with> 25 mM
donor concentrations quantitatively yielded TiO2 (e–)| Ru+ D+, and the corresponding …
