Patent number: 9117965Abstract: The invention is a method of forming a cadmium sulfide based buffer on a copper chalcogenide based absorber in making a photovoltaic cell. The buffer is sputtered in two steps the first being at low rates or relatively high pressures and the second at high rates or relatively low pressures. The resulting cell has good efficiency and according to one embodiment is characterized by a narrow interface between the absorber and buffer layers. The buffer is further characterized according to a second embodiment by a relatively high oxygen content.Type: GrantFiled: October 22, 2012Date of Patent: August 25, 2015Inventors: Melissa A. Mushrush, Todd R. Bryden, Kevin P. Capaldo, Scott A. Sprague

Patent number: 7824747Abstract: A light diffusing film for a back light display is described. The light diffusing film includes a unitary film consisting essentially of polycarbonate and a uniformly dispersed anti-static material in an amount sufficient to impart anti-static properties to the film. The anti-static material may comprise a fluorinated phosphonium sulfonate. The film may additionally include at least one textured surface for the low scattering of light. Alternatively, the film may additionally include a uniformly dispersed acrylic bulk scattering additive of particles having a mean particle size of from about 3 to about 10 microns and present in an amount from about 2 to about 7 percent by weight percent for the high scattering of light.Type: GrantFiled: December 28, 2007Date of Patent: November 2, 2010Assignee: Sabic Innovative Plastics IP B.V.Inventors: Grant Hay, Kevin P.

Publication number: 20030108710Abstract: A method for producing articles bearing patterned microstructures, e.g., optical film, information carrying substrates for optical recording media, etc. includes applying a radiation curable coating material to a surface of a base film substrate, passing the base film substrate and uncured coating through a compression nip defined by a nip roll and a casting drum having pattern master of the microstructures. The method further includes curing the radiation curable coating by directing radiation energy through the base film substrate from the surface opposite the surface having the coating thereon while the coating is in contact with the drum, thus causing microstructure pattern to be replicated in the cured coating layer.Type: ApplicationFiled: August 9, 2002Publication date: June 12, 2003Applicant: General Electric CompanyInventors: Dennis Joseph Coyle, Kevin P.

Publication number: 20030099808Abstract: A process for producing low birefringence and low stress thermoplastic polycarbonate film having a birefringence of less than about 20 nm from polycarbonate resin. The process consists of feeding a polycarbonate resin to an extruder, melting the polycarbonate resin, extruding the melted polycarbonate resin downwardly through an extrusion nozzle having the configuration of, forming a continuous film of melted resin, advancing the melted resin downwardly by essentially gravity into a gap between two calendering rolls which lie in a plane essentially perpendicular to the downward extrusion of the resin, cooling the polycarbonate film to below its glass transition temperature and advancing the cooled polymer to storage. The calendering rolls lie in a plane essentially perpendicular to the downward extrusion of the melted resin to wherein one roll is in a plane at an angle of about 30° from said perpendicular. The film is useful for optical media applications.Type: ApplicationFiled: August 13, 2002Publication date: May 29, 2003Applicant: General Electric CompanyInventors: Dennis Joseph Coyle, Kevin P.
