The present disclosure relates to a device that includes an irregular network of interconnected ridges in physical contact with a planar substrate and a perovskite layer, where the planar substrate include a support layer and a first charge selective contact layer, the first charge selective contact layer is positioned between the support layer and the interconnected ridges, each ridge includes a second charge selective contact layer and an insulating layer, the insulating layer is positioned between the first charge selective contact layer and the second charge selective contact layer, and the perovskite layer substantially covers the plurality of interconnected ridges and the underlying planar substrate.

All-back-contact photovoltaic devices using cracked film lithography

The present invention relates to catalysts, methods of making catalysts, and methods of using catalysts, where the catalysts include: at least one of a transition metal and a transition metal oxide supported by yttria-stabilized zirconia (YSZ), where the transition metal is promoted by at least one of an alkali metal and an alkaline-earth metal.

Methods of making YSZ supported catalyst, and methods of using the same

The present disclosure relates to an all-back-contact photovoltaic device that includes, in order, a substrate, a first electrode having a first surface, an insulator, a second electrode having a second surface, and an active material, where the insulator and the second electrode form a cavity, the active material substantially fills the cavity and is in physical contact with the first surface and the second surface, the insulator includes a first layer and a second layer with the second layer positioned between the first layer and the second contact, and the first layer is constructed of a first material that is different than a second material used to construct the second layer.

All-back-contact perovskite solar cells

Disclosed herein are CdTe-based solar cells that are successfully removed from their glass superstrate through a combination of lamination to a backsheet followed by thermal shock.

Controlled thermomechanical delamination of thin films

A catalytic membrane reactor and methods of operating and producing the same are provided that efficiently produces highly pure hydrogen (H) from ammonia (NH) as well as operates according to other chemical conversion processes. In one embodiment, a tubular ceramic support made from porous yttria-stabilized zirconia has an outer surface that is impregnated with a metal catalyst such as ruthenium and then plated with a hydrogen permeable membrane such as palladium. An inner surface of the ceramic support is impregnated with cesium to promote conversion of ammonia to hydrogen and nitrogen (N). The resulting catalytic membrane reactor produces highly pure hydrogen at low temperatures and with less catalytic loading. Therefore, ammonia can be used to effectively transport hydrogen for use in, for example, fuel cells in a vehicle.

Catalytic membrane reactor, methods of making the same and methods of using the same for dehydrogenation reactions

Disclosed herein are methods of producing metal sulfide materials, including cathode materials. In some embodiments, the metal sulfide material comprises a secondary cluster of metal sulfide nanoparticles surrounded by a carbon layer. The carbon layer may be created by carbonizing one or more polymer layers disposed about the secondary cluster. The carbonized layer may aid in optimizing performance of the cathode material. Also disclosed herein are methods, processes, devices, and systems for removing hydrogen sulfide from a waste stream. In some embodiments, the waste stream containing hydrogen sulfide is a gas. The waste stream can be combined with a solvent containing a metal-catalyst complex, and the reaction of hydrogen sulfide with the metal results in production of a hydrogen gas and a solid comprising metal sulfide.

Production of alkali sulfide cathode material and methods for processing hydrogen sulfide

The present invention relates to a method to synthesize ammonia at moderate conditions. The present invention also relates to a new chemical reactor configuration to achieve ammonia synthesis at moderate pressures and temperatures, and methods to make membranes for use in ammonia synthesis.

Ammonia synthesis at moderate conditions using hydrogen permeable membrane reactors

The present invention provides a hydrogen separation membrane based on nanoporous, composite metal carbide or metal sulfide coated membranes capable of high flux and permselectivity for hydrogen without platinum group metals. The present invention is capable of being operated over a broad temperature range, including at elevated temperatures, while maintaining hydrogen selectivity.

Stable catalyst layers for hydrogen permeable composite membranes

TaOand AlOthin films were fabricated by pulsed plasma-enhanced chemical vapor deposition (PECVD) with simultaneous delivery of Oand the metal precursor. By appropriately controlling the gas-phase environment self-limiting deposition at controllable rates (&#x2dc;1 &#x212b;/pulse) was obtained. The process was insensitive to substrate temperature, with a constant deposition rate observed from 90-350&#xb0; C. As-deposited TaOfilms under these conditions displayed good dielectric properties. Performance improvements correlate strongly with film density and composition as measured by spectroscopic ellipsometry and Fourier transform infrared spectroscopy. Pulsed PECVD eliminates the need for gas actuation and inert purge steps required by atomic layer deposition.
