Electrochemical energy can be produced by using solar energy to oxidize water, providing an abundant source of electrons, which are needed in fuel synthesis. The operation of an efficient and stable semiconductor nanocomposite anode, made of a protective TiO2 layer that protects a silicon substrate during photoelectrochemical water oxidation in both dark and light conditions, is now reported.
