Abstract
This communication describes electrochemical contacting of PbS quantum dot solids with liquid solutions of fast, outer-sphere redox couples to form both rectifying and non-rectifying junctions. Current-voltage data were consistent with junction formation near the semiconductor/liquid interface. The results are important because they show that electrochemical contacting provides a method to probe photovoltaic properties of quantum dot solids over a wide span of contacting energetics.
