  • Tungsten nitrido precursors for the CVD of tungsten nitride, carbonitride, and oxide films
    Patent number: 9540284
    Abstract: Embodiments of the invention are directed to a method of preparing a WNx, WNxCy, WNxOz, and WNxCyOz solid by the deposition of a WNx precursor at a temperature below 300° C. The WNx precursor is a tungsten nitrido complex. The deposition can be carried out using a tungsten nitrido complex as a single-source metal organic precursor. In an embodiment of the invention, the deposition can be performed to form a plurality of WNx, WNxCy, WNxOz, WNxCyOz nanoparticles.
    Type: Grant
    Filed: December 18, 2014

  • NANOCRYSTALLINE COPPER INDIUM DISELENIDE (CIS) AND INK-BASED ALLOYS ABSORBER LAYERS FOR SOLAR CELLS
    Publication number: 20130118585
    Abstract: Embodiments of the invention are to a copper indium diselenide (CIS) comprising nanoparticle where the nanoparticle includes a CIS phase and a second phase comprising a copper selenide. The CIS comprising nanoparticles are free of surfactants or binding agents, display a narrow size distribution and are 30 to 500 nm in cross section. In an embodiment of the invention, the CIS comprising nanoparticles are combined with a solvent to form an ink. In another embodiment of the invention, the ink can be used for screen or ink-jet printing a precursor layer that can be annealed to a CIS comprising absorber layer for a photovoltaic device.
