Measurement and validation of PbS nanocrystal energy levels

Abstract

Cyclic voltammetry was used to measure PbS nanocrystal (PbS-NC) energy levels. Accuracy of these measurements was justified by electron transfer experiments, with well known fullerene derivatives, which included photoluminescence quenching experiments and current density-voltage measurements of hybrid photovoltaic devices. It is believed that these energy level measurements, carried out on PbS-NCs under ambient conditions, would provide valuable information for the design and fabrication of optimized hybrid nanoelectronic devices. © 2008 American Institute of Physics.
