HyperSolar, Inc. announced that it has received the European Patent Office (EPO) decision to grant the patent entitled “Multi-junction artificial photosynthetic cell with enhanced photovoltages. This patent is jointly held with 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. The company has until June 6, 2019 to designate which countries in Europe it intends to validate the patent. The patent protects the Company’s Gen 2 proprietary design of a self-contained high-voltage solar hydrogen production device made up of billions of solar-powered water-splitting nanoparticles, per square centimeter. These nanoparticles consist of multiple layers of solar cells that increase the photovoltages of the nanoparticles for higher solar-to-hydrogen conversion efficiency. The nano-sized design of the structure enhances the light absorption by the solar cell thus requiring much less material compared to traditional film solar cells. The innovative integrated structures of high-density arrays of nano-sized high-voltage solar cells will serve as the core of the company’s future hydrogen production units. The high-voltage, high-light absorbing properties of the nanoparticle solar cells enable production of ultrathin solar cells with significantly lower amount of materials. The nanoparticle solar cells can be produced through a conventional roll-to-roll process which leads to substantially lower materials and manufacturing cost compared to conventional solar cells used in rooftop power applications.
