Abstract
Decomposition of water into hydrogen and oxygen by sunlight is accomplished by using a rhodate p-type semiconductor as cathode and an n-type semiconductor or a metal as anode. A cell exposed to sunlight using a rhodate cathode and an n-type TiO.sub.2 anode decomposes the contained water and also generates electric power.
