  • Combinatorial methods for making CIGS solar cells
    Patent number: 8927322
    Abstract: The present disclosure is directed to methods of forming different types of Cu2ZnSnS4 (CZTS) solar cells and Copper Indium Gallium DiSelenide (CIGS) solar cells that can be combinatorially varied and evaluated. These methodologies all incorporate the formation of site-isolated regions using a combinatorial processing tool and the use of these site-isolated regions to form the solar cell area. Therefore, multiple solar cells may be rapidly formed on a single substrate for use in combinatorial methodologies. Any of the individual processes of the methods described may be varied combinatorially to test varied process conditions or materials.
    Type: Grant
    Filed: May 3, 2011
    Date of Patent: January 6, 2015
    Assignee: Intermolecular, Inc.
    Inventors: Upendra Avachat, Tony Chiang, Craig Hunter, Jian Li, Guizhen Zhang
  • Combinatorial methods for developing superstrate thin film solar cells
    Patent number: 8835212
    Abstract: Methods for developing and investigating materials and processes for various layers used in manufacturing CdTe, CIGS, and CZTS TFPV superstrate devices using high productivity combinatorial techniques is described. Typical layers subjected to the HPC techniques include the buffer layers, absorber layers, and the contact interface layers.
