✦ Synopsis

Recent advances in the study of the dye sensitization of semiconductor electrodes are reviewed highlighting the characteristics of dye/semiconductor pairs with a high quantum yield, @, for electrons collected as current per photon absorbed by the dye. Photoelectrochemical data, picosecond fluorescence measurements, and flash photolysis results on high Q systems are discussed in relation to kinetic models of the injection process ia order to provide an overall evaluation of the current state of the understanding of the events following excitation of an excited dye adsorbed on a semiconductor surface.
