HyperSolar, the developer of a breakthrough technology to produce renewable hydrogen using sunlight and any source of water, announced that its artificial photosynthesis technology is now capable of producing 1.0 volt open circuit voltage for use in direct solar hydrogen production. This achievement represents a dramatic voltage increase over the previous 0.2 volt just 8 months ago, and 0.75 volt just 3 months ago.
It is well known that the theoretical voltage for splitting water into hydrogen and oxygen is 1.23 volts, and approximately 1.5 volts in real-world systems. Achieving 1.5 volts using inexpensive solar cells has eluded the world. For example, silicon solar cells are the most inexpensive and abundant, but their 0.7 volt is not enough to split water. Commercially available high voltage solar cells are unfortunately too expensive for use in hydrogen production.
HyperSolar is developing and intends to market a novel solar hydrogen generator that eliminates the expensive electrolyzer by integrating the electrolysis function directly into a solar cell.
