Sunlight into  Hydrogen:  "Hydrogen Solar of Guilford, England, and Altair Nanotechnologies are building a hydrogen-generation system that captures sunlight and uses the energy to break water molecules into hydrogen and oxygen. .. Hydrogen Solar CEO David Auty said his company's Tandem Cell technology uses two solar cells that together capture sunlight from every part of the ultraviolet spectrum. The interaction of photons with a semiconductor material causes a photoelectrochemical reaction that excites electrons and causes water molecules to break up into hydrogen and oxygen, according to Auty. Auty said Tandem Cells are coated with a layer containing metal oxide particles that are less than 30 nanometers thick and can convert sunlight energy into hydrogen with 8 percent efficiency. .. In October, the Department of Energy awarded (.pdf) $10 million in research grants to four groups also working on producing hydrogen from sunlight -- GE Global Research, the University of California at Santa Barbara, MVSystems and Midwest Optoelectronics.
