Patent number: 9688863Abstract: 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.Type: GrantFiled: June 15, 2016Date of Patent: June 27, 2017Assignee: Enki Technology, Inc.Inventors: Sina Maghsoodi, Brenor L.

Patent number: 9598586Abstract: 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.Type: GrantFiled: July 14, 2015Date of Patent: March 21, 2017Assignee: Enki Technology, Inc.Inventors: Brenor L.
