  • Laser-textured thin-film semiconductors by melting and ablation
    Patent number: 11393938
    Abstract: A photovoltaic device and a method of making the photovoltaic device are disclosed. The photovoltaic device may include a semiconductor layer epitaxially grown using a compound semiconductor material, such as a group III-V semiconductor material, wherein a surface of the semiconductor layer is textured via one or more laser pulses of a laser. The photovoltaic device may also include a dielectric layer deposited over the textured surface of the semiconductor layer, and a back metal reflector provided on the dielectric layer. The textured surface extends a path of light traveling through the photovoltaic device to increase absorption of the light within the photovoltaic device.
    Type: Grant
    Filed: April 2, 2019
    Date of Patent: July 19, 2022
    Assignee: UTICA LEASECO, LLC
    Inventors: Octavi Santiago Escala Semonin, Daniel Guilford Patterson, Reto Adrian Furler, Andrew James Ritenour
