## Abstract A series of new cobalt complexes [Co(LLL)~2~X~2~] were synthesized and evaluated as redox mediators for dyeโsensitized nanocrystalline TiO~2~ solar cells. The structure of the ligand and the nature of the counterions were found to influence the photovoltaic performance. The oneโelectron
## Experimental Section TiO 2 /CD/JK-2: The TiO 2 electrodes were immersed in a solution of CD in H 2 O (0.8 mm) and kept at room temperature for 12 h. The film was subsequently washed in absolute ethanol and dried. The TiO 2 electrodes were then immersed in a solution of JK-2 in EtOH (0.3 mm) and
