  • Copper-indium-gallium-chalcogenide nanoparticle precursors for thin-film solar cells
    Patent number: 9466743
    Abstract: Nanoparticles containing IUPAC group 11 ions, group 13 ions and sulfur ions are synthesized by adding metal salts and an alkanethiol in an organic solvent and promoting the reaction by applying heat. Nanoparticles are formed at temperatures as low as 200° C. The nanoparticles may be thermally annealed for a certain amount of time at a temperature lower than the reaction temperature (usually ˜40° C. lower) to improve the topology and narrow the size distribution. After the reaction is complete, the nanoparticles may be isolated by the addition of a non-solvent and re-dispersed in organic solvents including toluene, chloroform and hexane to form a nanoparticle ink. Additives may be incorporated in the reaction solution to tailor the final ink viscosity.

  • Halogen free syntheses of aminosilanes by catalytic dehydrogenative coupling
    Patent number: 9453035
    Abstract: Compounds and method of preparation of Si—X and Ge—X compounds (X=N, P, As and Sb) via dehydrogenative coupling between the corresponding unsubstituted silanes and amines (including ammonia) or phosphines catalyzed by metallic catalysts is described. This new approach is based on the catalytic dehydrogenative coupling of a Si—H and a X—H moiety to form a Si—X containing compound and hydrogen gas (X=N, P, As and Sb). The process can be catalyzed by transition metal heterogenous catalysts such as Ru(0) on carbon, Pd(0) on MgO) as well as transition metal organometallic complexes that act as homogeneous catalysts. The —Si—X products produced by dehydrogenative coupling are inherently halogen free. Said compounds can be useful for the deposition of thin films by chemical vapor deposition or atomic layer deposition of Si-containing films.
