HyperSolar, Inc., the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, today announced that it has jointly filed a patent application with the University of California, Santa Barbara (“UCSB”) for the “method of manufacture of multi-junction artificial photosynthetic cells.”
“The hydrogen fuel cell industry has been abuzz lately in part due to Walmart’s partnership with Plug Power, and Hyundai, BMW and other auto manufacturer’s commitment to hydrogen fuel,” said Tim Young, CEO of HyperSolar. “That being said, the infrastructure surrounding hydrogen production is as crucial as the fuel cell technology. We believe that our process of mimicking photosynthesis by splitting water molecules provides the lowest-cost and scalability that the industry will need as it continues to establish relationships with international brands and projects. This patent, which improves the durability and efficiency of the semiconductor, brings HyperSolar one step closer to achieving that goal.”
Inspired by expensive space shuttle multi-junction solar cells where different layers of semiconductor materials are stacked together to maximize solar conversion efficiency, this patent application claims a novel low cost and high voltage multi-junction solar cell made from a single material. The single material has a low cost per watt and the voltage achieved so far in the laboratory is very close to the critical 1.5 volts required for splitting water molecules into hydrogen and oxygen. If successfully developed, the company believes that this technology can produce renewable hydrogen from water (“green hydrogen”) that is cost competitive with hydrogen that is currently produced from natural gas (“brown hydrogen”).
HyperSolar’s technology is based on the concept of developing a low-cost, submersible hydrogen production particles that can split water molecules using sunlight without any other external systems or resources – acting as artificial photosynthesis
