  • Patent number: 11359301
    Abstract: The invention relates to a method of processing of materials using a moving interface, the method comprising: providing a working material, the working material comprising a substrate with a metallic film on at least one side of the substrate; providing an energy source adjacent to the working material, where the energy source is electrical current between a cathode and the working material as an anode; providing for relative controlled movement between the working material and the energy source, where the relative controlled movement is a motor attached to the working material via a linkage; activating the energy source such that the energy processes the working material; moving the energy source and/or the working material relative to the other to control the amount of processing of the working material achieved by the energy, where the processing of the working material is anodization; immersing the working material at a controlled speed into an anodizing bath equipped with a cathode; starting anodization

  • Patent number: 10790403
    Abstract: A system and method are presented for the design and fabrication of arrays of vacuum photodiodes for application to solar power generation. In a preferred embodiment, each photodiode cell comprises a microfabricated enclosure with a hermetically sealed vacuum, an absorptive photocathode, and a transparent anode, wherein the photocathode and the anode are separated by a vacuum gap of less than about 20 micrometers. Light incident on the photocathode through the anode leads to a flux of electrons passing from the photocathode across the vacuum gap to the anode. In a further preferred embodiment, the photocathode is backed by a reflection layer with, e.g., controlled diffuse reflection, thus increasing the efficiency of energy extraction. An array of such cells may be manufactured using automated thin-film deposition and micromachining techniques.
