Synthesis of Earth-Abundant Chalcogenide Nanoparticlesy Chalcogenide Nanoparticles
Researchers at Purdue University have developed an innovative method that is related to the synthesis of multinary chalcogenide nanoparticles comprising of Cu, Zn, Sn, S, and Se. The main compound created is Cu2ZnSn(SySe1-y)4, whereby Cu/(Zn+Sn) can be substantially less than 1, but greater than 0.5; Zn/Sn can be greater than, equal to, or less than 1; and y can be between 0 and 1. This method would allow for improved thin films for photovoltaic applications because of tin and zinc's natural abundance in the earth's crust and the relatively low toxicity.
