摘要： The present invention is directed to a luminescent waveguide device, and methods of making thereof, that may be used to convert solar energy into electricity. In particular, the present invention relates to extracting and waveguiding luminescence generated in a scattering medium so as to improve luminescent concentrator performance. By stacking one or a pair of transparent plates of refractive index slightly smaller than that of luminescent plate but still larger than that of air, a much greater fraction of re-emitted light by the embedded luminescent particles can be extracted so that the detrimental effect of particle scattering can be minimized. Additionally, by additionally using a high-efficiency diffractive optic component in the structure to redirect the re-emitted photons with angles falling into the escape zone to much larger angles so these otherwise outgoing photons can be waveguided by total internal reflection. These improvements minimize the critical-angle loss and increase the output light intensity at the ends of the waveguide.

摘要： Disclosed herein are systems and methods for improving the performance of a luminescent concentrator. Performance may be enhanced by incorporating a reflector capable of blocking re-emitted photons from the luminescent material used to make frequency down conversion with a narrow reflection band, while allowing broad transmission of incident sunlight. The reflection band of the reflector that spectrally matches to the bandwidth of re-emission from the luminescent material acts as a luminescence cavity to prevent the outgoing re-emission that cannot be waveguided by total internal reflection to the photovoltaic device(s) located at the side edges of the concentrator. Further embodiments include using inorganic phosphors specifically as luminescent materials

摘要： Disclosed herein are systems and methods of a combinatorial synthesis technique that produces functional materials from a plurality of chemical elements with a compositional gradient either continuously varying across the sample, or where the mole fractions are discretely varied. A contactless heating mechanism, such as a pulsed laser, provides in situ thermal activation necessary for promoting and controlling reaction between precursors, inter-diffusion of precursor atoms, and thermal annealing that is essential for crystallization of deposited materials. The heating may be spot selective and temperature variable so that the required thermal annealing may be conducted in a combinatorial manner.

摘要： Disclosed are methods of reducing the bandgap of a metal oxide by alloying a binary oxide with a Group VI element that is isovalent with oxygen. The Group VI element substitutes for at least a portion of the oxygen in the binary oxide to form the alloyed, ternary oxide. Such ternary oxide electrodes are useful as photoelectrodes in photoelectrochemical cells that spontaneously, as a result of solar power, cleave (split) water molecules to produce hydrogen gas. Exemplary ternary metal oxide alloys useful in the present embodiments include W[(VI)xO1−x]3 and Ti[(VI)xO1−x]2, and the Group VI element may be S, Se, and Te, and combinations thereof.
