Scientists Make Major Breakthrough In Sustainable Hydrogen Production

By Brian Westenhaus - Jan 18, 2023,

> Scientists have created a new type of solar panel that could help drive down the cost of sustainable hydrogen.

> The new solar panel achieved 9% efficiency in converting water into hydrogen and oxygen – mimicking a crucial step in natural photosynthesis.

> Zetian Mi, U-M professor of electrical and computer engineering, said, “In the end, we believe that artificial photosynthesis devices will be much more efficient than natural photosynthesis, which will provide a path toward carbon neutrality.”

University of Michigan scientists developed a new kind of solar panel achieving 9% efficiency in converting water into hydrogen and oxygen – mimicking a crucial step in natural photosynthesis. Outdoors, it represents a major leap in the technology, nearly 10 times more efficient than solar water-splitting experiments of its kind.

But the biggest benefit is driving down the cost of sustainable hydrogen. This is enabled by shrinking the semiconductor, typically the most expensive part of the device. The team’s self-healing semiconductor withstands concentrated light equivalent to 160 suns.
