Title: Roger M Hawk: Innovator in Solar Technology and Silicon Deposition
Introduction
Roger M Hawk is a notable inventor based in Conway, AR (US), recognized for his contributions to solar energy and silicon film technology. With a total of 3 patents, Hawk has made significant strides in enhancing the efficiency of energy production and material deposition processes.
Latest Patents
One of Hawk's latest inventions is the Solar Co-Generator, which produces both heat energy and electricity. This innovative device utilizes a solar concentrator to direct sunlight into a container lined with solar cells and filled with a thermal transfer fluid. The fluid is designed to be transparent to certain wavelengths of light, allowing for electricity generation, while being opaque to longer wavelengths, particularly in the infrared spectrum. This design enables the infrared portion of sunlight to heat the thermal transfer fluid, which is then used to transfer heat through a storage facility via a heat exchange mechanism. The thermal transfer fluid enhances the efficiency of photovoltaic generation by preventing overheating of the solar cells due to infrared radiation. The fluid may consist of a mixture containing barium sulfate and a suspension of zinc sulfide phosphors, and a fluorescing anti-reflective coating can be applied to the solar cells to further boost efficiency.
Another significant patent is the Apparatus for the Deposition and Film Formation of Silicon on Substrates. This novel apparatus employs an aerosol generating technique to deposit silicon powder of optimal particle size onto high melting point substrates, which can include semiconducting, insulating, and conducting materials such as silicon, sapphire, and molybdenum. The aerosolized silicon powder is charged and electrostatically deposited onto the substrates, which are then heat-treated at specific times and temperatures to form polycrystalline silicon films.
