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: The present invention provides methods for making pnictide compositions, particularly photoactive and/or semiconductive pnictides. In many embodiments, these compositions are in the form of thin films grown on a wide range of suitable substrates to be incorporated into a wide range of microelectronic devices, including photovoltaic devices, photodetectors, light emitting diodes, betavoltaic devices, thermoelectric devices, transistors, other optoelectronic devices, and the like. As an overview, the present invention prepares these compositions from suitable source compounds in which a vapor flux is derived from a source compound in a first processing zone, the vapor flux is treated in a second processing zone distinct from the first processing zone, and then the treated vapor flux, optionally in combination with one or more other ingredients, is used to grow pnictide films on a suitable substrate.

Abstract: Cantilever chemical vapor sensors that can be tailored to respond preferentially in frequency by controlling the location of deposition of an adsorbing layer. Cantilever chemical vapor sensor having a base, one or more legs and a tip are fabricated using a gold layer to promote deposition of a sorbing layer of a polymeric material in a desired location, and using a chromium layer to inhibit deposition of the sorbing layer in other locations. Sorbing layers having different glass temperatures Tg and their effects are described. The methods of making such cantilever chemical vapor sensors are described.

Abstract: A light-driven electrolytic cell that uses water vapor as the feedstock and that has no wires or connections whatsoever to an external electrical power source of any kind. In one embodiment, the electrolytic cell uses a proton exchange membrane (PEM) with an IrRuOx water oxidation catalyst and a Pt black water reduction catalyst to consume water vapor and generate molecular oxygen and a chemical fuel, molecular hydrogen. The operation of the electrolytic cell using water vapor supplied by a humidified carrier gas has been demonstrated under varying conditions of the gas flow rate, the relative humidity, and the presence or absence of oxygen. The performance of the system with water vapor was also compared to the performance when the device was immersed in liquid water.

Abstract: Electrical structures and devices may be formed and include an organic passivating layer that is chemically bonded to a silicon-containing semiconductor material to improve the electrical properties of electrical devices. In different embodiments, the organic passivating layer may remain within finished devices to reduce dangling bonds, improve carrier lifetimes, decrease surface recombination velocities, increase electronic efficiencies, or the like. In other embodiments, the organic passivating layer may be used as a protective sacrificial layer and reduce contact resistance or reduce resistance of doped regions. The organic passivation layer may be formed without the need for high-temperature processing.

Methods for forming such a structure include forming the semiconductor structures on a substrate, casting a binder material onto the substrate to embed the semiconductor structures in the binder material, and separating the binder material from the substrate at the substrate. These methods provide for the retention of the orientation and order of highly ordered semiconductor structures in the separated binder material.
