  • Methods of producing uniform intrinsic layer
    Patent number: 10424687
    Abstract: A photovoltaic device includes an intrinsic layer having two or more sublayers. The sublayers are intentionally deposited to include complementary concave and convex shapes. The sum of these layers resulting in a relatively flat surface for deposition of n- or p-doped layers. The photovoltaic device is optionally bifacial.
    Type: Grant
    Filed: September 16, 2016
    Date of Patent: September 24, 2019
    Assignee: Aptos Energy, LLC
    Inventors: Thanh Ngoc Pham, Joe Feng
  • Photovoltaic devices including curved sub-layers
