Publication number: 20110315211Abstract: A carrier substrate, includes a substrate especially having a glass function, transparent at least in the visible and near-infrared ranges and receiving a conducting electrode which is transparent at least in the visible and near-infrared ranges, this electrode carrier substrate being intended to constitute, in combination with functional elements, a solar cell. This carrier substrate is such that: the electrode includes a micromesh made of conducting material having submillimeter-sized openings; and this micromesh is in contact with an at least slightly conducting antireflection coating facing that one of the functional elements with which it is intended to be in contact. An aspect of the present invention also relates to the use of such a carrier substrate as constituent element of a solar cell and to a process for fabricating the substrate.Type: ApplicationFiled: September 24, 2009Publication date: December 29, 2011Applicant: Saint-Gobain Glass FranceInventors: Bernard Nghiem, Eddy Royer, Emmanuelle Peter, Georges Zagdoun

Publication number: 20110177324Abstract: One subject of the invention is a glass substrate coated with a continuous temporary protection film, said film essentially consisting of a stack of discernible colloidal polymer particles. Another subject of the invention is a process for coating a glass substrate with a continuous temporary protection film, in which process an aqueous dispersion of colloidal particles of at least one water-insoluble solid polymer is deposited on at least one surface of said substrate and then the film thus obtained is dried at a temperature above the glass transition temperature of said at least one polymer but not exceeding 50° C.Type: ApplicationFiled: May 25, 2009Publication date: July 21, 2011Applicant: SAINT-GOBAIN GLASS FRANCEInventors: Georges Zagdoun, Eddy Royer
