Solar Hydrogen Production "breakthrough".

Using a simple solar cell and a photo anode made of a metal oxide, scientists in Europe have successfully stored nearly 5% of solar energy chemically in the form of hydrogen. The significance of the advance is based on the design of the solar cell, which is much simpler than that of the high-efficiency triple-junction cells based on amorphous silicon or class III-V semiconductors.
