Abstract
The ultrafast optical technique was used to study the multiexciton states in size- and shape-controlled CdSe and PbSe nanocrystals (NC). The effect of the zero-dimensional to one-dimensional transition on the efficiency of multiparticle Auger recombination using a series of quantum rods with different aspect ratios was also investigated. The transition from the three-to two-particle recombination process was observed as the nanocrystal aspect ratio was increased. The effect of quantum confinement on impact ionization using a series of PbSe NC of different sizes was also investigated. The results show that impact ionization process in NCs can be used to increase the power conversion efficiency of NC-based solar cells.
