HyperSolar, Inc., the developer of a technology to produce renewable hydrogen, using sunlight and any source of water, today announced that it was recently granted a patent from the Australian Government entitled “Multi-junction artificial photosynthetic cell with enhanced photovoltages” issued as Patent No. 2015231504. This patent is jointly owned by HyperSolar and the Regents of the University of California, as a result of the collaboration with the University of California, Santa Barbara in developing the technology. Evidence of the granted patent can be viewed here at http://pericles.ipaustralia.
The patent protects the Company’s proprietary design of a self-contained high voltage solar-to-hydrogen device made up of billions of solar-powered water-splitting nanoparticles, per square centimeter. These nanoparticles consist of multiple layers of solar cells stacked on top of each other to increase the photovoltages for higher solar-to-hydrogen conversion efficiency.
The important aspect of the patented technology is the integrated structures of high-density arrays of nano-sized high voltage solar cells as the core of hydrogen production units. The nanoparticles can be produced on ultra-thin sheets through a roll-to-roll process which requires substantially lower materials cost and manufacturing cost compared to conventional solar cells used in rooftop power applications. Further the manufacturing process uses low physical and carbon footprint and maximizes raw material utilization.
Commented HyperSolar’s CEO Tim Young, “With abundant land and sun, Australia offers huge opportunity for our renewable hydrogen. Both Toyota and Hyundai have committed to bringing hydrogen fuel-cell cars to Australia. The patent is critical to protecting the intellectual property related to the development our GEN 2 technology. It complements our other granted and pending patents and puts us a step closer to realizing our goal of renewable, low-cost hydrogen produced near or at the point of use, such as at hydrogen stations or in Amazon fulfillment centers where hydrogen fuel-cell powered forklifts are widely used.”
HyperSolar’s research is focused on developing a completely renewable, low-cost and submersible hydrogen production particle that can split water molecules using the power of the sun, emulating the core functions of photosynthesis. Each particle is a complete hydrogen generator that contains a novel high voltage solar cell bonded to chemical catalysts by a proprietary encapsulation coating.
