  • OPTOELECTRONIC DEVICE WITH NON-CONTINUOUS BACK CONTACTS
    Publication number: 20190221698
    Abstract: An optoelectronic device is disclosed. The optoelectronic device comprises a semiconductor structure; a plurality of contacts on the front side of the semiconductor structure; and a plurality of non-continuous metal contacts on a back side of the semiconductor structure. In an embodiment, a plurality of non-continuous back contacts on an optoelectronic device improve the reflectivity and reduce the losses associated with the back surface of the device.

  • Thin-film semiconductor optoelectronic device with textured front and/or back surface prepared from template layer and etching
    Patent number: 10008628
    Abstract: A method for providing a textured layer in an optoelectronic device is disclosed. The method includes depositing a template layer on a first layer. The template layer has significant inhomogeneity either in thickness or in composition, or both, including the possibility of forming one or more islands to provide at least one textured surface of the island layer. The method also includes exposing the template layer and the first layer to an etching process to create or alter at least one textured surface. The altered at least one textured surface is operative to cause scattering of light.
    Type: Grant
