  • Patent number: 9406829
    Abstract: A method to improve operation of a CdTe-based photovoltaic device is disclosed, the method comprising the steps of depositing a semiconductor absorber layer adjacent to a substrate, depositing a semiconductor buffer layer adjacent to the semiconductor layer, and annealing at least one of the semiconductor absorber layer and the semiconductor buffer layer with one of a laser and a flash lamp.
    Type: Grant
    Filed: June 27, 2014
    Date of Patent: August 2, 2016
    Assignee: First Solar, Inc.
    Inventors: Pratima Addepalli, Benyamin Buller, Markus Gloeckler, Akhlesh Gupta, David Hwang, Andrei Los, Rick Powell, Rui Shao, Gang Xiong, Ming Lun Yu, San Yu, Zhibo Zhao
  • Publication number: 20160126395
    Abstract: A photovoltaic device includes a substrate structure and at least one Se-containing layer, such as a CdSeTe layer. A process for manufacturing the photovoltaic device includes forming the CdSeTe layer over a substrate by at least one of sputtering, evaporation deposition, CVD, chemical bath deposition process, and vapor transport deposition process. The process can also include controlling a thickness range of the Se-containing layer.
    Type: Application
