Abstract :

Colloidal Nanocrystal Quantum Dots (NQDs) have been considered ideal building blocks for functional materials because of their physical properties tunability based on quantum confinement effect. Recent advances in the use of hot carriers and multiple-excition from the high energy photon in NQDs have demonstrated potential efficiency improvements when used in photovoltaics. Here, strategies to facilitate carrier transfer/transport while preserving optical characteristics of isolated NQDs will be discussed. Specifically, synthesis and characterizations of 1) the fabrication of neat NQD solids (assembled NQD films) with modified surfaces by attaching ligands or by applying physical processes such as heat annealing [J. Phys. Chem. C (2011), 115(3), 607] and 2) coupling NQDs to one-dimensional nanostructures such as single-walled carbon nanotubes (SWNTs) [ACS Nano, (2010) 4(1), 324] will be presented.
