  • Patent number: 7663057
    Abstract: An ink for forming CIGS photovoltaic cell active layers is disclosed along with methods for making the ink, methods for making the active layers and a solar cell made with the active layer. The ink contains a mixture of nanoparticles of elements of groups IB, IIIA and (optionally) VIA. The particles are in a desired particle size range of between about 1 nm and about 500 nm in diameter, where a majority of the mass of the particles comprises particles ranging in size from no more than about 40% above or below an average particle size or, if the average particle size is less than about 5 nanometers, from no more than about 2 nanometers above or below the average particle size. The use of such ink avoids the need to expose the material to an H2Se gas during the construction of a photovoltaic cell and allows more uniform melting during film annealing, more uniform intermixing of nanoparticles, and allows higher quality absorber films to be formed.

  • Patent number: 7485588
    Abstract: This invention relates to textile substrates to which a finishing treatment has been applied during the manufacturing process. Such a finishing treatment provides improved water and/or oil repellency and stain and soil resistance. The finishing treatment generally includes a repellent agent, a stain release agent, and a particulate component. Other compounds may be added to the treatment, such as stain-blocking agents, crosslinking agents, coupling agents, antimicrobial agents, and pH adjusting agents. The components of the finishing treatment are generally applied to the textile substrate using an application process that results in layered structures on the surface of the treated substrate, which has been found to greatly improve the durability of the treatment. Such treated textile substrates thus exhibit excellent stain and soil resistance and water and/or oil repellency properties.

  • Patent number: 7390676
    Abstract: A method and apparatus for the manipulation of colloidal particulates and biomolecules at the interface between an insulating electrode such as silicon oxide and an electrolyte solution. Light-controlled electrokinetic assembly of particles near surfaces relies on the combination of three functional elements: the AC electric field-induced assembly of planar aggregates; the patterning of the electrolyte/silicon oxide/silicon interface to exert spatial control over the assembly process; and the real-time control of the assembly process via external illumination. The present invention provides a set of fundamental operations enabling interactive control over the creation and placement of planar arrays of several types of particles and biomolecules and the manipulation of array shape and size. The present invention enables sample preparation and handling for diagnostic assays and biochemical analysis in an array format, and the functional integration of these operations.
