Patent number: 8354136Abstract: A method for producing a thick film includes disposing a precursor solution onto a substrate to form a precursor film. The precursor solution contains precursor components to a rare-earth/alkaline-earth-metal/transition-metal oxide including a salt of a rare earth element, a salt of an alkaline earth metal, and a salt of a transition metal in one or more solvents, wherein at least one of the salts is a fluoride-containing salt, and wherein the ratio of the transition metal to the alkaline earth metal is greater than 1.5. The precursor solution is treated to form a rare earth-alkaline earth-metal transition metal oxide superconductor film having a thickness greater than 0.8 ?m. precursor solution.Type: GrantFiled: November 24, 2009Date of Patent: January 15, 2013Assignee: American Superconductor CorporationInventors: Xiaoping Li, Thomas Kodenkandath, Edward J.

Publication number: 20120060900Abstract: A process described herein provides an economical means for producing the oxide-based buffer layers using a wet chemical CSD process wherein the desired buffer layer material results from the evaporation of a chemical already containing the material in solution. Thus, no residual liquid chemical elements remain after deposition, and as there is no reaction to create the buffer material, as is the case with CdS CBD, the liquid elements in CSD have sufficiently long shelf life after mixing to as to improve manufacturability and further reduce waste. Furthermore, as there is no in-chamber reaction to create the buffer material solution, there are many options for delivering said solution to the CIGS absorber layer. Finally, as the oxide films for the CdS replacement have inherently better transmission in the blue spectrum, aggressive thinning of films to improve current generation is unnecessary.Type: ApplicationFiled: September 8, 2011Publication date: March 15, 2012Applicant: Ascent Solar Technologies, Inc.Inventors: Thomas A. Kodenkandath, Anne Gatchell, Venugopala R. Basava

Patent number: 7893006Abstract: Under one aspect, a method of making a superconductor wire includes providing an oxide superconductor layer overlaying a substrate; forming a substantially continuous barrier layer over the oxide superconductor layer, the barrier layer including metal; depositing a layer of metal particles over the barrier layer, said depositing including applying a liquid including metal particles over the barrier layer; and sintering the layer of metal particles to form a substantially continuous metal layer over the barrier layer. In one or more embodiments, the oxide superconductor layer is oxygen-deficient, and the method may include oxidizing the oxygen-deficient oxide superconductor layer. At least a portion of the sintering and the oxidizing may occur simultaneously, for example by performing them at an oxygen partial pressure and a temperature sufficient to both sinter the metal particles and to oxidize the oxygen-deficient oxide superconductor layer.Type: GrantFiled: March 23, 2007Date of Patent: February 22, 2011Assignee: American Superconductor CorporationInventors: Yibing Huang, Thomas Kodenkandath, Joseph Lynch, Martin W.
