Abstract: The solar fuels generator includes an ionically conductive separator between a gaseous first phase and a second phase. A photoanode uses one or more components of the first phase to generate cations during operation of the solar fuels generator. A cation conduit is positioned provides a pathway along which the cations travel from the photoanode to the separator. The separator conducts the cations. A second solid cation conduit conducts the cations from the separator to a photocathode.

Abstract: A solar fuels generation system includes a first reactor that contains a first solution in which a charge carrier is reduced to a reduced charge carrier. The system also includes a second reactor that contains a second solution in which the reduced charge carrier reduces protons so as to generate hydrogen gas.

Abstract: A photoanode includes a passivation layer on a light absorber. The passivation layer is more resistant to corrosion than the light absorber. The photoanode includes a surface modifying layer that is location on the passivation layer such that the passivation layer is between the light absorber and the surface modifying layer. The surface modifying layer reduces a resistance of the passivation layer to conduction of holes out of the passivation layer.

Abstract: The present invention provides methods of making photovoltaic devices incorporating improved pnictide semiconductor films. In particular, the principles of the present invention are used to improve the surface quality of pnictide films. Photovoltaic devices incorporating these films demonstrate improved electronic performance. As an overview, the present invention involves a methodology that metalizes the pnictide film, anneals the metalized film under conditions that tend to form an alloy between the pnictide film and the alloy, and then removes the excess metal and at least a portion of the alloy. In one mode of practice, the pnictide semiconductor is Zinc phosphide and the metal is Magnesium.
