Patent number: 8231848Abstract: Ternary and quaternary Chalcopyrite CuInxGa1-xSySe2-y (CIGS, where 0?x and y?1) nanoparticles were synthesized from molecular single source precursors (SSPs) by a one-pot reaction in a high boiling solvent using salt(s) (i.e. NaCl as by-product) as heat transfer agent via conventional convective heating method. The nanoparticles sizes were 1.8 nm to 5.2 nm as reaction temperatures were varied from 150° C. to 190° C. with very high-yield. Tunable nanoparticle size is achieved through manipulation of reaction temperature, reaction time, and precursor concentrations. In addition, the method developed in this study was scalable to achieve ultra-large quantities production of tetragonal and quaternary Chalcopyrite CIGS nanoparticles.Type: GrantFiled: April 10, 2012Date of Patent: July 31, 2012Assignee: Sun Harmonics LtdInventors: Yuhang Ren, Chivin Sun, Kai Shum
