Abstract

We have succeeded in developing a new-type Si electrode with metal nano-contact and surface methylation, which shows excellent and stable photovoltaic characteristics in aqueous redox electrolytes. The electrode has achieved solar decomposition of hydrogen iodide into hydrogen and iodine under no external bias, with a high solar-to-chemical conversion efficiency ø_chem^s of 7.4%. The present success is of much interest in that it has opened a new way to realize high-efficiency and low-cost solar energy conversion.
