HyperSolar Reaches Another Milestone Towards Commercially Viable Solar-to-Hydrogen Efficiency

HyperSolar, Inc. the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, today announced that it recently was able to nearly triple photocurrents in its novel solar cell, an important breakthrough to increase the rate of hydrogen ("H2") production as the Company seeks to scale its technology to support real world energy applications.

The volume of hydrogen produced is directly related to the amount of photocurrents generated utilizing submersible, integrated solar cell materials. The Company, in partnership with University of Iowa, was able to nearly triple this amount of photocurrents generated from its novel solar cell materials. This breakthrough constitutes an important milestone in the Company's effort to split water molecules for the production of renewable hydrogen fuel.

In terms of next steps, HyperSolar seeks to optimize the catalyst loading onto the solar cells in order to apply the increased efficiency of the photocurrents, resulting in a more powerful hydrogen production process. "This breakthrough on the negative side (cathode reduction reaction) of the solar hydrogen production device allows us to leverage the success we achieved earlier with high photocurrents obtained on the positive side of the device (anode oxidation reaction)," said Dr. Joun Lee, Chief Technology Officer at HyperSolar. "We believe this achievement to be crucial, as it is necessary to match the currents on both sides of the electrode to achieve optimum hydrogen production efficiency."
