20080299327 | Surface Energy Control Methods For Color Filter Printing - Black matrix (BM) material is deposited on glass and patterned to form walls that define an array of wells. Various surface treatments and masking schemes are utilized to achieve surface energy control of the BM glass. The surface treatments include one or more of chemically treating the BM walls by depositing hydrophobic self-assembled monolayers on the uppermost wall surfaces, and plasma treatments to control the surface energy of the various BM glass surfaces. Masking processes include backside exposure and development of photoresist, and maskless, self-aligned photo-patterning of the monolayers. Color filter ink is then injected into each well from an ink jet print head. The high surface energy of the lower and side wall surfaces facilitates wetting of the ink, and the low surface energy of the monolayers prevents intermixing of ink between adjacent wells. The ink then dries to form a color filter in each well. | 12-04-2008 |
20090047558 | MICRO-MACHINED FUEL CELLS - An improved fuel cell is described. The invention addresses the problem of mechanical failure in thin electrolytes. One embodiment varies the thickness of the electrolyte and positions at least either the anode or cathode in the recessed region to provide a short travel distance for ions traveling from the anode to the cathode or from the cathode to the anode. A second embodiment uses a uniquely shaped manifold cover to allow close positioning of the anode to the cathode. Using the described structures results in a substantial improvement in fuel cell reliability and performance. | 02-19-2009 |
20120288673 | Depositing Calcium Fluoride Template Layers for Solar Cells - A biaxially textured crystalline layer formed on a substrate is provided. The biaxially textured crystalline layer includes an oriented CaF | 11-15-2012 |
20120292725 | DEPOSITION AND POST-PROCESSING TECHNIQUES FOR TRANSPARENT CONDUCTIVE FILMS - In one embodiment, a method is provided for fabrication of a semitransparent conductive mesh. A first solution having conductive nanowires suspended therein and a second solution having nanoparticles suspended therein are sprayed toward a substrate, the spraying forming a mist. The mist is processed, while on the substrate, to provide a semitransparent conductive material in the form of a mesh having the conductive nanowires and nanoparticles. The nanoparticles are configured and arranged to direct light passing through the mesh. Connections between the nanowires provide conductivity through the mesh. | 11-22-2012 |
20130276877 | Composition and Method For Upconversion of Light and Devices Incorporating Same - An up-converting electrode and a solar cell that combines the up-converting electrode are disclosed. The up-converting electrode comprises a material that up-converts light from longer wavelengths to shorter wavelengths and an electrically conductive material. The electrically conductive material increases the efficiency of the up-converting material such that more light is up-converted. The up-converting electrode can also serve as an electrical contact for the solar cell. | 10-24-2013 |
20140270671 | Confocal and Concave 1D Photonic Crystal Resonant Cavities with Ultra-low Mode Volume - A 1D nanobeam photonic crystal cavity is provided that includes a substrate, where the substrate includes a dielectric medium, and a series of cutout features in the substrate, where each cutout feature includes a first curved surface and a second curved surface, where the first curved surface and the second curved surface form a meniscus shape, where the series of cutout features include an array of sizes of the meniscus shape cutouts, where edges of the meniscus shape and the array of sizes are disposed to form a pair of opposing parabolic dips proximal to a central region of the series of cutout features. | 09-18-2014 |
20150197844 | Depositing Calcium Fluoride Template Layers for Solar Cells - A biaxially textured crystalline layer formed on a substrate using ion beam assisted deposition (IBAD) is provided. The biaxially textured crystalline layer includes an oriented CaF | 07-16-2015 |
20150367616 | PRESSURE-TRANSFERRED COMPONENTS - In accordance with various embodiments, a front surface of a donor substrate is placed upon a surface of an acceptor substrate, with the front surface having donor material formed thereupon. A portion of the donor material is transferred from the donor substrate to a target surface region of the acceptor substrate, by applying a localized-force to a back surface of the donor substrate that is opposite the donor material in the region being transferred. The force is applied in such a way that, if or when the donor and acceptor substrates are physically separated, a portion of the donor material remains on the acceptor substrate in the region(s) the force was applied. | 12-24-2015 |
