Robust Water-Splitting Technology

Caption: This drawing shows two electrodes splitting water into oxygen (left) and hydrogen (right). The electrodes are connected via an external voltage source. The illuminated silicon electrode (left) is protected from the surrounding electrolyte by a 2-nm film of nickel and uses light energy to assist in the water-splitting process.
