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: A method of aligning microwires includes modifying the microwires so they are more responsive to a magnetic field. The method also includes using a magnetic field so as to magnetically align the microwires. The method can further include capturing the microwires in a solid support structure that retains the longitudinal alignment of the microwires when the magnetic field is not applied to the microwires.

Abstract: The present invention uses a treatment that involves an etching treatment that forms a pnictogen-rich region on the surface of a pnictide semiconductor film The region is very thin in many modes of practice, often being on the order of only 2 to 3 nm thick in many embodiments. Previous investigators have left the region in place without appreciating the fact of its presence and/or that its presence, if known, can compromise electronic performance of resultant devices. The present invention appreciates that the formation and removal of the region advantageously renders the pnictide film surface highly smooth with reduced electronic defects. The surface is well-prepared for further device fabrication.

Abstract: A solar fuels generator includes an anolyte and a catholyte in contact with a separator. The separator is configured such that the pH of the anolyte and the pH of the catholyte are each held at a steady state pH level during operation of the solar fuels generator. The steady state pH level of the anolyte is different from the steady state pH level of the catholyte.

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.
