  • Devices and methods for making polycrystalline alloys
    Patent number: 11207731
    Abstract: A process for preparing alloy products is described using a self-sustaining or self-propagating SHS-type combustion process with point-source ignition, preferably a laser, in a pressurized vessel. Binary, ternary and quaternary alloys can be formed with control over polycrystalline structure and bandgap. Methods to tune the bandgap and the alloys formed are described. The alloy products may be doped. Preferably sulfides, tellurides or selenides are formed. Cooling during reaction takes place.
    Type: Grant
    Filed: March 23, 2017
    Date of Patent: December 28, 2021
    Assignee: First Solar, Inc.
    Inventors: Shrinivas Govindarajan, Michael Latusek, Christopher Wagner, Feng Yan

  • Process for making powder alloys containing cadmium and selenium
    Patent number: 10026855
    Abstract: A process for preparing alloy products powders is described using a self-sustaining or self-propagating SHS-type combustion process. Binary, ternary and quaternary alloy having cadmium, selenium and optionally a third element X or Y selected from Group VIA (such as S or Te) or from group IIB (such as Zn or Hg). The alloy products may be doped or not with a wide variety of other elements. The process involves heating to ignition, maintaining an elevated temperature less than melting for homogenization, followed by cooling and crushing. An optional de-oxidation process may follow to further purify the alloy and balance the stoichiometry.
