Sang Hoon Nam has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9452929
    Abstract: Provided are a photoelectrode including a zinc oxide hemisphere, a method of fabricating the same, and a dye-sensitized solar cell using the same. The photoelectrode includes a conductive substrate, a zinc oxide hemisphere disposed on the conductive substrate, and a porous metal oxide layer covering the zinc oxide hemisphere. Light scattering effects of photoelectrodes can be increased, and recombination losses of electrons can be minimized to improve photovoltaic properties.
    Type: Grant

  • Patent number: 8637186
    Abstract: An electrode for a battery and a method for manufacturing the same are disclosed. The electrode for a battery according to the present invention comprising silicon nanostructures integrally formed on a silicon thin film and having a period array can reduce the internal resistance, have better charge transport properties, and reduce the structural stress, thereby exhibiting high storage capacity, high efficiency charge/discharge characteristics, and long charge/discharge cycle characteristics. Moreover, the method for manufacturing the electrode for a battery according to the present invention can simply and easily form a nanopattern with nanostructures on a silicon thin film using laser interference lithography (LIL) and dry etching.
