Additionally, the applying a multiphoton curable photoreactive composition comprising hydantoin hexaacrylate and a photoinitiator system may be applied to a substrate and a portion of the multiphoton curable photoreactive composition may be at least partially cured to form an at least partially cured structure.
Abstract:
A method of forming a working mold including: placing a substrate (610) on an electrode in a chamber, the substrate having at least a first structured surface (620) and the substrate including a thermoset polymeric material; introducing a release (630) layer forming gas into the chamber, wherein the release layer forming gas includes silicon containing gas and oxygen gas in an atomic ratio of not greater than about 200; providing power to the electrode to create a plasma of the release layer forming gas within the chamber; and depositing a release layer formed from the release layer forming gas on at least the first structured surface of the substrate to form.a working mold.
Abstract:
The inventors of the present disclosure recognized that elimination or reduction of the silver paste and/or silver busbars on the front and/or rear surfaces of solar cells and solar modules would advantageously lower the total cost of the solar cell and/or solar module. The inventors of the present disclosure recognized that the silver paste on the front and rear surface of solar cells or solar modules can be eliminated or the amount of silver paste reduced by replacing the silver busbars with a solderable tape including a conductive metal foil and a nonconductive adhesive.

In one embodiment, a semiconductor component, such as a wavelength converter wafer, is described wherein the wavelength converter is bonded to an adjacent inorganic component with a cured bonding layer comprising polysilazane polymer. The wavelength converter may be a multilayer semiconductor wavelength converter or an inorganic matrix comprising embedded phosphor particles. In another embodiment, the semiconductor component is a pump LED component bonded to an adjacent component with a cured bonding layer comprising polysilazane polymer. The adjacent component may the described wavelength converter(s) or another component comprised of inorganic material(s) such as a lens or a prism. Also described are methods of making semiconductor components such as wavelength converters and LED's.
Abstract:
Lightguides, devices incorporating lightguides, processes for making lightguides, and tools used to make lightguides are described. A lightguide includes light extractors arranged in a plurality of regions on a surface of the lightguide. The orientation of light extractors in each region is arranged to enhance uniformity and brightness across a surface of the lightguide and to provide enhanced defect hiding. The efficiency of the light extractors is controlled by the angle of a given light extractor face with respect to a light source illuminating the light guide.
Abstract:
A supported catalyst is provided comprising catalyst metal nanoparticles having an average particle size of 3.0 nm or less, or mo re typically 2.0 nm or less, and typically having a standard deviation of particle size of 0.5 nm or less, which are supported on support particles at a loading of 30% or more. Typical catalyst metals are selected from platinum, palladium, ruthenium, rhodium, iridium, osmium, molybdenum, tungsten, iron, nickel and tin. Typical support particles are carbon. A method of making a supported catalyst is provided comprising the steps of :a)providing a solution of metal chlorides of one or more catalyst metals in solvent system containing at least one polyalcohol, typically ethylene glycol containing less than 2% water; b)forming a colloidal suspension of unprotected catalyst metal nanoparticles by raising the pH of the solution, typically to a pH of 10 or higher, and heating said solution, typically to 125°C or higher; c)adding support particles to the colloidal suspension; and d)depositing the unprotected catalyst metal nanoparticles on the support particles by lowering the pH of said suspension, typically to a pH of 6.5 or lower.
