Abstract

Their unique optical properties have made semiconductor nanocrystals (NCs) the subject of intense research for use in solar cells. Even in the simplest scenario, in which semiconductor NCs are used as replacements for dyes in dye-sensitized cells, there is great potential for increased efficiency because of the broad-band, high-cross-section absorbance spectra, increased photostability and "carrier multiplication" (CM) demonstrated by semiconductor NCs. Lead selenide (PbSe) NCs are an especially promising candidate, because they possess near-to-mid infrared optical band gaps, and have demonstrated efficient CM. However, PbSe NCs are unstable under ambient conditions, undergoing band gap shifts and reduced surface quality that preclude their use in solar cells. Investigation of this instability has led to a method for stabilizing PbSe NCs with unique advantages to possible solar cell application. We will present the results of that study, along with a comparison study performed on the new cadmium-stabilized PbSe NCs.
