(133f) Solution Phase Synthesis of Inorganic Nanoparticle, Films and Electronic Devices

Metal chalcogenides provide us with a class of inorganic semiconducting materials that are quite useful for optoelectronic applications. In this talk, we will present the synthesis of several chalcogenides, their films and devices. In particular, we will discuss our result related to Cu(In,Ga)Se₂, Cu₂ZnSnSe₄, and their derivatives. We will also present the synthesis of Cu₃VVI₄ class of materials and their improved optoelectronic properties for devices such as solar cells. Finally, we will discuss the chemistry behind the versatile amine-thiol solvents, which are capable of dissolving a large number of metals and salts providing us with molecular precursor inks for the synthesis of chalcogenide nanoparticles and thin films. As an illustration, we will show its ability to tune synthesis of Pb chalcogenide particles in sizes ranging from a few nanometers to micrometers.
