摘要：

An easily accessible homoleptic complex [Ru(L3)(3)](2+) containing a dissymmetrical bipyridine (1-3) substituted by a pyrrole and a carboxylic group has been evaluated in a dye-sensitized solar cell. The new dye displayed extended absorption domain, high absorbance, and a promising 65% IPCE value. Higher scores were reached using a cobalt-iron mediator instead of the usual LiI/I-2 couple for regeneration of the Ru-II state. Transient absorption spectroscopy was used to explain the mediator effect.
