HyperSolar Demonstrates Successful Hydrogen Production Using Readily Available Commercial Silicon Solar Cells

SANTA BARBARA, CA – February 21, 2017 HyperSolar, Inc. (OTCQB: HYSR), the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, today announced that it had successfully produced renewable hydrogen using commercially available low-cost silicon solar cells (supplied by Midwest Optoelectronics, LLC "MWOE") protected with HyperSolar’s proprietary coating.

The Company’s research team used a patent pending solar-cell/membrane assembly that produces hydrogen and oxygen separately on two different sides of the solar cells. The membrane prevents mixing of hydrogen and oxygen (hazardous gaseous mixture) resulting in the extraction of “pure hydrogen,” necessary for use in fuel cells that can power cars like the Toyota Mirai and Honda Clarity, as well as industrial power equipment. This integrated assembly also prevents recombination of hydrogen and oxygen into water at the catalyst surface, greatly improving the overall hydrogen utilization efficiency.  


In addition, the key to this success is the use of HyperSolar’s patent pending electroactive coating formulated to protect the solar cells from corrosion during prolonged hydrogen production. The success of utilizing silicon solar cells provided by outside manufacturers represents yet another indication of the potential of HyperSolar’s technology for economically viable production of hydrogen.

“While the science itself is challenging, we have always looked for simple, economic, and scalable methods for hydrogen production,” said Dr. Joun Lee, Chief Technology Officer of HyperSolar. “When fully developed, we believe our technology will be easier to deploy, and will have source-to-use energy cost competitive to the current commercial method which uses natural gas to produce hydrogen.”

HyperSolar is now building a 1 square foot hydrogen generator prototype using the commercial silicon cells. Long-term stability testing of the commercial triple junction silicon solar cells for hydrogen production is currently in progress.

“Our goal is to lower the cost of producing renewable hydrogen to compete with natural gas reformed hydrogen,” said Tim Young, CEO of HyperSolar. “We are very encouraged by the production levels achieved using MWOE-supplied low cost triple-junction cells. The cost of these cells, plus the catalysts necessary for hydrogen production, while not yet on par with the hydrogen produced from steam reforming of natural gas, show great promise for another method of producing hydrogen without using fossil fuels. While our ultimate goal is to complete development of our nanoparticle technology using earth-abundant materials, we are going to explore market opportunities with  these readily available solar cells, that when incorporated into our proprietary prototype device, produce pure hydrogen.” 

About HyperSolar, Inc.

HyperSolar is developing a breakthrough, low cost technology to make renewable hydrogen using sunlight and any source of water, including seawater and wastewater. Unlike hydrocarbon fuels, such as oil, coal and natural gas, where carbon dioxide and other contaminants are released into the atmosphere when used, hydrogen fuel usage produces pure water as the only byproduct. By optimizing the science of water electrolysis at the nano-level, our low cost nanoparticles mimic photosynthesis to efficiently use sunlight to separate hydrogen from water, to produce environmentally friendly renewable hydrogen. Using our low cost method to produce renewable hydrogen, we intend to enable a world of distributed hydrogen production for renewable electricity and hydrogen fuel cell vehicles.  To learn more about HyperSolar, please visit our website at
