  • Patent number: 9688863
    Abstract: Disclosed herein are polysilsesquioxane-based anti-reflective coating (ARC) compositions, methods of preparation, and methods of deposition on a substrate. In one embodiment, the polysilsesquioxane of this disclosure is prepared in a two-step process of acid catalyzed hydrolysis of organoalkoxysilane followed by addition of tetralkoxysilane that generates silicone polymers with >40 mol % silanol based on Si-NMR. These high silanol siloxane polymers are stable and have a long shelf-life in polar organic solvents at room temperature. Also disclosed are low refractive index ARC made from these compositions with and without additives such as porogens, templates, thermal radical initiator, photo radical initiators, crosslinkers, Si—OH condensation catalyst and nano-fillers. Also disclosed are methods and apparatus for applying coatings to flat substrates including substrate pre-treatment processes, coating processes and coating curing processes including skin-curing using hot-air knives.

  • Patent number: 9598586
    Abstract: Glass coating materials and methods are disclosed for the coating of glass substrates used in the manufacturer of photovoltaic solar modules such that the coating enhances the reliability of the module by reducing its susceptibility to potential induced degradation (PID). Coating materials are disclosed that reduce soiling on the front surface of the glass; that increase the surface resistivity of the glass and that repel moisture and that seal the surface from the ingress of moisture. Further electrically conductive coatings are disclosed that reduce the electric field between the front and back surfaces of the glass and hence reduce ion mobility within the glass and transport from the interior glass surface to the solar cell. There are additional configuration choices for fine tuning associated with separately optimizing the exterior and interior glass coating. Finally, coating processes and methods are disclosed for coating glass substrates with the disclosed materials.

  • Patent number: 9376593
    Abstract: Disclosed herein are coating materials and methods for applying a top-layer coating that is durable, abrasion resistant, highly transparent, hydrophobic, low-friction, moisture-sealing, anti-soiling, and self-cleaning to an existing conventional high temperature anti-reflective coating. The top coat imparts superior durability performance and new properties to the under-laying conventional high temperature anti-reflective coating without reducing the anti-reflectiveness of the coating. Methods and data for optimizing the relative thickness of the under-layer high temperature anti-reflective coating and the top-layer thickness for optimizing optical performance are also disclosed.

  • Publication number: 20150255748
    Abstract: Barrier stacks according to embodiments of the present invention achieve good water vapor transmission rates with a reduced number of dyads (i.e., polymer layer/oxide layer couple). In some embodiments, the barrier stack includes one or more dyads comprising a first polymer decoupling layer and a second barrier layer on the first layer. A passivation layer is wet deposited on the second layer of at least one of the dyads. The passivation layer includes a wet coated and cured curable material that seals the localized defects in the underlying barrier layer, and the barrier stack including the passivation layer has a water vapor transmission rate that is lower than a water vapor transmission rate of a barrier stack not including the passivation layer.
