Fast electron transfer: Picosecond charge transfer between CdTe quantum dots and a novel water-soluble organo-Ir dye is shown. This process allows hot electron transfer from the nanoparticles to the organic component before cooling is complete and before Auger relaxation processes can compete for the carrier's excess energy. Understanding and controlling fast charge transfer is a key to making improved solar-energy conversion devices.
