We have demonstrated a new method for synthesizing monodisperse ultra-small PbSe NRs with the diameter approaching 2 nm (Eg > 1.2 eV). The PbSe NRs show n-type properties and high electron mobility as measured by using field-effect transistors. The PbSe NRs with narrow diameters are used for the first time in solar cells and their improved efficiency is demonstrated when used together with QDs.
