Abstract: Laser pyrolysis reactor designs and corresponding reactant inlet nozzles are described to provide desirable particle quenching that is particularly suitable for the synthesis of elemental silicon particles. In particular, the nozzles can have a design to encourage nucleation and quenching with inert gas based on a significant flow of inert gas surrounding the reactant precursor flow and with a large inert entrainnient flow effectively surrounding the reactant precursor and quench gas flows. Improved silicon nanoparticle inks are described that has silicon nanoparticles without any surface modification with organic compounds. The silicon ink properties can be engineered for particular printing applications, such as inkjet printing, gravure printing or screen printing. Appropriate processing methods are described to provide flexibility for ink designs without surface modifying the silicon nanoparticles.

Abstract: High quality silicon inks are used to form polycrystalline layers within thin film solar cells having a p-n junction. The particles deposited with the inks can be sintered to form the silicon film, which can be intrinsic films or doped films. The silicon inks can have a z- average secondary particle size of no more than about 250 nm as determined by dynamic light scattering on an ink sample diluted to 0.4 weight percent if initially having a greater concentration. In some embodiments, an intrinsic layer can be a composite of an amorphous silicon portion and a crystalline silicon portion.

Abstract: Light-driven flow reactors are configured with an aerosol delivery apparatus that is designed to improve the reactive process with respect to forming uniform product compositions at higher rates. In particular, the reactant delivery system can deliver an aerosol having an average droplet size of no more than about 50 microns, and in some embodiments 20 microns, and with less than 1 droplet in 10,000 having a diameter greater than 5 times the average droplet size. In some embodiments, the edge of the aerosol generator can be placed within about 6 centimeters of the edge of the light beam passing through the reaction chamber. The average aerosol velocity can be no more than about 5 meters per second. In some embodiments, the aerosol generator can comprise a non-circular opening and a gas permeable structure that is used to generate a mist that is delivered from the apparatus as an aerosol.

Abstract: Collections of phosphor particles have achieved improved performance based on improved material properties, such as crystallinity. Display devices can be formed with these improved submicron phosphor particles. Improved processing methods contribute to the improved phosphor particles, which can have high crystallinity and a high degree of particle size uniformity. Dispersions and composites can be effectively formed from the powders of the submicron particle collections.
