Nanotechnology and Solar Power: New Developments

March 25th, 2009 · No Comments · Main Content

This process uses solar energy to split water into hydrogen and oxygen. Hydrogen can be used to run cars, or can produce energy using fuel cells.

Hydrogen production from solar power might become a commercial reality now. A major increase in efficiency of this process is a new development. We may see a lot more of this type of energy production in the future.

Scientists in Japan discovered in 1970 that semiconductor oxide photoanodes can harness the photons from solar radiation and used them to split a water molecule into hydrogen and oxygen, but process was too inefficient to be viable.

The UALR team, working with researchers at the University of Nevada, Reno, and supported by the U.S. Department of Energy and the Arkansas Science and Technology Authority (ASTA), has reported an 80 percent increase in efficiency with a new process.
