  • Patent number: 11114714
    Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc includes a casing having a header assembly comprising a ceramic plate formed by co-firing a metallic-containing paste in first and second via holes extending through a green-state ceramic. The ceramic plate is joined to a metal ring by a gold-braze to form the header assembly that is secured to an open-ended metal container by a weld to provide the casing. The fill material resulting from sintering the metallic-containing paste provides a first conductive pathway to the anode current collector contacting an anode active material and a second conductive pathway to a cathode current collector contacting a cathode active material. A solid electrolyte activates the anode and cathode while also serving as a separator. Outer surfaces of the first and second conductive pathways are configured for electrical connection to a load.

  • Patent number: 10873045
    Abstract: This invention relates to a novel structure of photovoltaic devices (e.g. photovoltaic cells also called as solar cells) are provided. The cells are based on the micro or nano scaled structures which could not only increase the surface area but also have the capability of reducing the reflection and increasing the absorption of incident light. More specifically, the structures are based on 3D structure which are made of electric materials covering semiconductors, insulators, dielectric, polymer, and metallic type materials. By using such structures reflection loss of the light from the cell is significantly reduced, increasing the absorption, which results in increasing the conversion efficiency of the solar cell, and reducing the usage of material while increasing the flexibility of the solar cell. The structures can be also used in other optical devices wherein the reflection loss and absorption are required to enhance significantly improve the device performances.
