Patent number: 9242401Abstract: The present invention is directed to the use of injection molding to form polymeric interlayers directly between two rigid substrates that are positioned so that after injection of the melted polymeric material and after cooling, the resulting multiple layer panel functions as a safety panel that can be used in any appropriate conventional safety glazing application. Methods of the present invention utilize a relatively low molecular weight polymer, multiple injection points, mold compression, and/or a heated substrate in order to facilitate the injection of polymer into the relatively narrow space between glazing substrates that is typically found in safety glazings.Type: GrantFiled: August 23, 2006Date of Patent: January 26, 2016Assignee: Solutia Inc.Inventors: Aristotelis Karagiannis, Francois Andre Koran, Ping Yuan

Patent number: 8124868Abstract: The present invention provides a thin film photovoltaic module that has a protective substrate, such as glass, that has been contoured to define a space that allows air to avoid entrapment by a bus bar on the thin film photovoltaic device. The contouring of the protective substrate greatly facilitates the deairing and lamination of the module because it reduces or eliminates the amount of trapped air during lamination. Photovoltaic modules of the present invention can be processed with a minimum of waste caused by deairing and related lamination problems.Type: GrantFiled: December 16, 2008Date of Patent: February 28, 2012Assignee: Solutia Inc.Inventors: Francois Andre Koran, Stephen Joseph Norton, Khanh Duc Tran

Publication number: 20100065105Abstract: The present invention provides a thin film photovoltaic module that has a protective substrate, such as glass, that has been contoured to define a space that overlies a bus bar on the thin film photovoltaic device. The contouring of the protective substrate greatly facilitates the deairing and lamination of the module because it reduces or eliminates the amount of trapped air and the degree to which the underlying polymeric material is forced to flow during lamination. Photovoltaic modules of the present invention can be processed with a minimum of waste caused by deairing and related lamination problems.Type: ApplicationFiled: September 12, 2008Publication date: March 18, 2010Inventors: Francois Andre Koran, Stephen Joseph Norton, Khanh Duc Tran
