Abstract

Semiconductor quantum dots (QDs) are the subject of intensive research worldwide due to a number of novel properties, which make them of interest for both fundamental science and technological applications. QDs are of particular interest for solar cell applications due to their ability to increase efficiency via the generation of multiexcitons from a single photon. The efficiency of multiexciton generation (MEG) in colloidal QDs is determined by the competition between MEG and other hot electron-cooling processes. Core/shell QDs with type-II band alignment offers extra degrees of freedom in mediating both the optical dipoles and the Coulomb interaction between charges in such structures for the benefit of elevated MEG efficiency.
