Abstract:
A method for the preparation of copper indium gallium diselenide/disulfide (CIGS) nanoparticles utilizes a copper-rich stoichiometry. The copper-rich CIGS nanoparticles are capped with organo-chalcogen ligands, rendering the nanoparticles processable in organic solvents. The nanoparticles may be deposited on a substrate and thermally processed in a chalcogen-rich atmosphere to facilitate conversion of the excess copper to copper selenide or copper sulfide that may act as a sintering flux to promote liquid phase sintering and thus the growth of large grains. The nanoparticles so produced may be used to fabricate CIGS-based photovoltaic devices.

Claim (Index 21):
CIGS nanoparticles prepared a process, the process comprising:\n mixing salts selected from the group consisting of copper salts, indium salts and gallium salts in a solvent at a first temperature to produce a reaction solution; adding an organo-chalcogen precursor to the reaction solution; heating the reaction solution to a first temperature while stirring for a first time interval; heating the reaction solution to a second temperature and adding a second chalcogen precursor over a second time interval; stirring the reaction solution at the second temperature for a third time interval; cooling the reaction solution to a third temperature and stirring for a fourth time interval; cooling the reaction solution to room temperature; and isolating the nanoparticles.
