权利人:FRANKLIN AND MARSHALL COLLEGE
摘要:This invention relates to a process for the phase-controlled synthesis of ternary and quaternary mixed-metal sulfide nanoparticles by reacting soft metal ions with hard metal ions in a high-boiling organic solvent in the presence of a complexing and activating ligands to control the reactivity of the metal ions. Ternary and quaternary mixed metal sulfides nanoparticles of copper, sulfur, and iron, aluminum, tin, and silicon are preferred. This invention also relates to the phase controlled preparation of polymorphs of bornite nanoparticles and the phase controlled preparation of stabilized α- and γ-chalconite nanoparticles.

摘要:Materials and methods for preparing Cu 2 XSnY 4 nanoparticles, wherein X is Zn, Cd, Hg, Ni, Co, Mn or Fe and Y is S or Se, (CXTY) are disclosed herein. The nanoparticles can be used to make layers for use in thin film photovoltaic (PV) cells. The CXTY materials are prepared by a colloidal synthesis in the presence of labile organo-chalcogens. The organo-chalcogens serves as both a chalcogen source for the nanoparticles and as a capping ligand for the nanoparticles.

摘要:Materials and methods for preparing Cu 2 ZnSnS 4 (CZTS) layers for use in thin film photovoltaic (PV) cells are disclosed herein. The CZTS materials are nanoparticles prepared by a colloidal synthesis in the presence of a labile organothiol. The organothiol serves as both a sulphur source and as a capping ligand for the nanoparticles.
