  • Methods of growing CdTe-based materials at high rates
    Patent number: 10134590
    Abstract: Systems and methods for growing high-quality CdTe-based materials at high growth rates are provided. According to an aspect of the invention, a method includes depositing a first CdTe-based layer on a CdTe-based template at a rate of greater than 1 ?m/min. Each of the first CdTe-based layer and the CdTe-based template has a single-crystal structure and/or a large-grain polycrystalline structure. The depositing is performed by physical vapor deposition.
    Type: Grant
    Filed: March 27, 2017
    Date of Patent: November 20, 2018
    Assignee: Alliance for Sustainable Energy, LLC

  • CdTe devices and method of manufacturing same
    Patent number: 9147793
    Abstract: A method of producing polycrystalline CdTe materials and devices that incorporate the polycrystalline CdTe materials are provided. In particular, a method of producing polycrystalline p-doped CdTe thin films for use in CdTe solar cells in which the CdTe thin films possess enhanced acceptor densities and minority carrier lifetimes, resulting in enhanced efficiency of the solar cells containing the CdTe material are provided.
