  • Colloidal dispersion of a material in a divided state and consisting of metal chalcogenide in an aqueous medium, material in a divided state, and uses thereof
    Patent number: 9525095
    Abstract: A colloidal dispersion of a metal chalcogenide material in divided state in an aqueous liquid phase selected from the group consisting of aqueous solutions and solutions including a mixture of water and at least one solvent that is miscible with water, wherein the carbon element of the material is present in a proportion of less than 2.5 wt. % as determined by elemental analysis, the concentration of the material in the colloidal dispersion is more than 40 g/l, and the colloidal dispersion has a charge potential value which is negative and the absolute value of which is higher than 20 mV.

  • Solid material in the divided state, process for the production of such a material, and use of such a material in a photovoltaic cell
    Patent number: 8574538
    Abstract: The invention relates to a solid material with the following formula (A): (Cu+1a-u; Ag+1u; Zn+2b-v-(y/2); Cd+2v; Sn+4c-w-(y/2); 1X+4w; 2X+3y; S?2x)(A), in which the solid material: is in divided state in the form of particles having a mean equivalent diameter of 15 nm to 400 nm; has, according to X-ray diffraction analysis of the solid material, a unique crystalline structure; is suitable for forming a stable dispersion of at least one solid material with formula (A) in a liquid, referred to as dispersion liquid, made up of at least one compound with a value of ?p higher than 8 and a value of ?H higher than 5.
