Solar Water Splitting Record Broken by More Than 10%

September 16, 2015 | Leave a Comment

An international team has succeeded in considerably increasing the efficiency for direct solar water splitting. Using a tandem solar cell whose surfaces have been selectively modified, the old record of 12.4 percent that stood for 17 years was overtaken to 14 percent.  The group’s research paper has been published in Nature Communications in front of […]

New Materials For Solar Water Splitting to Hydrogen

February 26, 2014 | Leave a Comment

University of Wisconsin-Madison researchers have combined cheap, oxide-based materials to split water into hydrogen and oxygen gases using solar energy with a solar-to-hydrogen conversion efficiency of 1.7 percent, the highest reported for any oxide-based photoelectrode system.  The big deal is the lost cost angle. Generating electricity is not the only way to turn sunlight into […]
