Systems and methods disclosed herein are directed towards the fabrication of a solar absorber comprising an IR reflector layer deposited on a substrate; a first cermet layer deposited in contact with the IR reflector layer; a second cermet layer deposited in contact with the first cermet layer; a first anti-reflection coating layer deposited in contact with the second cermet layer; a second anti-reflection coating layer deposited in contact with the first anti-reflection coating layer. A sputtering process may be used to deposit some or all of the layers, and the YSZ layers in each cermet layer may be deposited with a tuned partial oxygen pressure in order to form a layer that is oxygen-deficient.

Selective solar absorbers with tuned oxygen deficiency and methods of fabrication thereof

A solar thermal photovoltaic device, and method of forming same, includes a solar absorber and a spectrally selective emitter formed on either side of a thermally conductive substrate. The solar absorber is configured to absorb incident solar radiation. The solar absorber and the spectrally selective emitter are configured with an optimized emitter-to-absorber area ratio. The solar thermal photovoltaic device also includes a photovoltaic cell in thermal communication with the spectrally selective emitter. The spectrally selective emitter is configured to permit high emittance for energies above a bandgap of the photovoltaic cell and configured to permit low emittance for energies below the bandgap.

Spectrally-engineered solar thermal photovoltaic devices

Solar power conversion system. The system includes a cavity formed within an enclosure having highly specularly reflecting in the IR spectrum inside walls, the enclosure having an opening to receive solar radiation. An absorber is positioned within the cavity for receiving the solar radiation resulting in heating of the absorber structure. In a preferred embodiment, the system further contains an energy conversion and storage devices thermally-linked to the absorber by heat conduction, convection, far-field or near-field thermal radiation.

Substantially pure water is produced via desalination using a directional solvent that directionally dissolves water but does not dissolve salt. The directional solvent is heated to dissolve water from the salt solution into the directional solvent. The remaining highly concentrated salt water is removed, and the solution of directional solvent and water is cooled to precipitate substantially pure water out of the solution.

A system and method for energy-efficient and environmentally-friendly recovery of bitumen aims at recovering unconventional oil in an environmentally friendly and sustainable way that has the potential of eliminating the need of natural gas currently employed for steam production and power generation. The system and method aims at providing low temperature steam for the stimulation of the formation by means of solar radiation. In addition, the system and method provides a novel solution for hydrogen production that does not employ reforming of natural gas. Furthermore, the use of thermoelectric devices in combination with low temperature steam can be employed to power an electrolysis plant to generate the hydrogen necessary to produce synthetic oil.
