Abstract

Nanocrystalline Ti[O.sub.2] solar cells sensitized with InAs quantum dots are reported. The solar cells have shown lower power efficiency under higher light intensity, due to both mass transport limitations of the redox relay and the increased charge recombination from the back reaction of electrons in Ti[O.sub.2] with holes in quantum dots (QDs).
