Publication number: 20220077337Abstract: A cover sheet (7) for a photovoltaic panel (4), the cover sheet (7) comprising a transparent substrate (8) and a coating (9) on the substrate (8), the coating (9) being such that the cover sheet (8) is more reflective to light of a first range of wavelengths in the infrared spectrum than to a second range of wavelengths in the visible spectrum; in which the coating (9) comprises alternating layers of first (11, 13) and second (12, 14) materials, with the first material (11, 13) having a higher refractive index than the second material (12, 14) and being a transparent conducting oxide such as indium tin oxide (ITO). Methods of manufacture including annealing the first material and/or depositing it at elevated temperatures are also discussed.Type: ApplicationFiled: December 20, 2019Publication date: March 10, 2022Inventors: Piotr Michal Kaminski, Adam Michael Law, Lewis David Wright, John Michael Walls

Patent number: 9562283Abstract: The invention relates to apparatus and a method for depositing material onto substrates, particularly optical substrates, to form a coating thereon. The apparatus and method incorporates the use of a series of magnetrons provided to be controlled to sputter deposit material provided in targets mounted therein, on to the substrates. There is provided a voltage to the magnetrons to operate the same and the level of voltage which is required to form required coating or coating layer characteristics is determined by using monitoring apparatus, at least when forming the coating or coating layer for the first time. The appropriate voltage level data for operation of the magnetrons can be held in a database and subsequently used to control the voltage level when forming an identified coating or layers of coatings.Type: GrantFiled: September 26, 2005Date of Patent: February 7, 2017Assignee: Applied Multilayers LLCInventors: Desmond Gibson, John Michael Walls

Patent number: 8206562Abstract: The invention relates to a method and apparatus for the application of material to form a layer of an organic electroluminescent device. The material is sputter deposited typically from at least one target of material held in respect to a magnetron in a coating chamber. The magnetrons used can be unbalanced magnetrons and/or are provided with other magnetrons and/or magnet arrays in a closed field configuration. The material is found to be deposited in a manner which prevents or minimises damage to the device and hence reduces or removes the need for a barrier layer to be applied.Type: GrantFiled: February 16, 2006Date of Patent: June 26, 2012Assignees: Cambridge Display Technology Limited, System Control Technologies LimitedInventors: John Michael Walls, Desmond Gibson, William Young, Nalinkumar Patel, Nicoletta Anathassopoulou

Publication number: 20090297787Abstract: The invention relates to the formation of optical lens including a coating, typically, an anti-reflective (AR) coating which provides improved characteristics of the lens. The invention provides for a method and apparatus for forming the coated lens in which there is provided a sheet material with the coating applied to at least one surface thereof. At least part of the sheet material is then placed into a mold and located so as to form an external surface of the lens, the base of which is formed by introducing, typically by injection, a material into the mold and during which molding process the material and sheet material join together to form the optical lens with the coating.Type: ApplicationFiled: February 26, 2007Publication date: December 3, 2009Inventors: Michael Hanney, Christopher John Ferrari, Des Gibson, John Michael Walls

Patent number: 6143143Abstract: The invention relates to apparatus for use in the coating of surfaces of substrates by Physical Vapor Deposition systems (PVD) wherein the deposition in material is applied onto the said surfaces by the sputtering of the same using the PVD system. The invention provides means for preventing sputtering material from applying or landing onto surfaces other than which is desired to be coated in the said coating process. The masking means allow the prevention and/or removal of such material which is known as backscattered material and the invention described claims protection for several embodiments and methods of achieving this thereby improving subsequent adhesion propertied and optical quantities, if applicable, of the coating.Type: GrantFiled: September 29, 1995Date of Patent: November 7, 2000Assignee: Applied Vision LimitedInventors: John Michael Walls, Alaric Graham Spencer, Norman Henry White, Alan Robert Waugh

Patent number: 6090248Abstract: The invention relates to apparatus for depositing of materials onto at least one substrate mounted on a substrate carrier provided for rotation in a material depositing zone in a vacuum chamber and causing a reaction of the said material to form a coating having desired properties. In a first aspect of the invention there is provided a loading chamber in selective interconnection with the vacuum chamber whilst maintaining a vacuum therein and in a second aspect the carrier and/or the vacuum chamber walls are provided with linear protrusions to restrict the flow of reactive gases in the chamber and thereby reduce the occurrence of arcing and both aspects allowing the dimensions of the coating apparatus to be reduced in comparison to conventional coating apparatus.Type: GrantFiled: April 19, 1996Date of Patent: July 18, 2000Assignee: Applied Vision LimitedInventors: Norman Henry White, Allen Robert Waugh, Alaric Graham Spencer, John Michael Walls

Patent number: 6090247Abstract: The current invention relates to the provision of apparatus for depositing layers of material onto substrates (2) mounted on a carrier (4) all provided in a vacuum chamber (6) wherein the material is deposited by sputtering of targets of the material from activated magnetrons (7, 7') and the deposited material is reacted by providing a reaction producing means (9) which allows the coating material on the substrates to be conditioned to have the required characteristics. The invention provides that any, or any combination, of the material depositing means and/or reaction producing means are formed from either two magnetrons or a magnetron and counter electrode arrangement which are powered by an alternating voltage power supply which allows a reduction in the occurence of arcing and thereby the dimensions of the apparatus in comparison to conventional apparatus can be substantially reduced.Type: GrantFiled: November 17, 1995Date of Patent: July 18, 2000Assignee: Applied Vision LimitedInventors: Norman Henry White, Allen Robert Waugh, Alarie Graham Spencer, John Michael Walls, Hussein J'Afer
