摘要：

Tunnel barrier photoelectrodes, with a thin inorganic tunnel barrier layer that isolates the semiconductor electrode from the electrolyte while allowing current flow across the interface, are a possible solution to the problem of photocorrosion in solar water splitting. In this approach, selection of the semiconductor for the light absorber is decoupled from selection of the tunnel barrier material that provides chemical stability. Here we demonstrate a proof-of-principle of this approach with TiO2/MgO tunnel barrier photoelectrodes. (C) 2010 American Institute of Physics. [doi:10.1063/1.3479055]
