Long-Lived Charge Separated State in NiO-Based p-Type Dye-Sensitized Solar Cells with Simple Cyclometalated Iridium Complexes.
Three new cyclometalated Ir complexes were prepd. and studied on nanocryst. NiO cathodes. Nanosecond transient absorption spectroscopy expts. show they present a surprisingly slow geminate charge recombination upon excitation on NiO, representing thus the 1st examples of simple sensitizers with such feature. These complexes were used in dye-sensitized solar cells using nanocryst. NiO film as semiconductor. The long-lived charge sepd. state of these Ir complexes make them compatible with other redox mediators than I3-/I-, such as a Co electrolyte and enable to reach significantly high open circuit voltage.
