Abstract: A method for manufacturing at least one photovoltaic cell includes the following steps: (a) providing at least one plate, the plate having a first face and a second face opposite the first face; (b) providing a support device; (c) positioning the plate placing the first face of the plate in contact with the support device; (d1) forming a first conductive material on the first face of the plate; (d2) forming a second conductive material on the second face of the plate. At least one of the first and second conductive materials is transparent, the support device includes at least one wire, and, during all or part of step (d1), the first face of the plate bears on the wire.

Abstract: A photovoltaic module includes a first protective element, a second protective element, photovoltaic cells that are located between the first protective element and the second protective element, an envelope in which the photovoltaic cells are encapsulated. The envelope links the first protective element to the second protective element and includes a first portion that is located between the photovoltaic cells and the first protective element, and a second portion that is located between the photovoltaic cells and the second protective element. The disassembly method includes separating the photovoltaic cells with respect to the first protective element and cutting the first portion of the envelope by an abrasive wire.

Abstract: An abrasive sawing or polishing substrate includes a substrate, a binder C1 covering at least a portion of the substrate, and abrasive particles having an at least partial coating, C2.

Abstract: Provided are alternative fabrication methods and compositions for an electrochemical cell. The methods of the present invention are applicable to the manufacture of polymer-cased lithium-ion secondary battery cells. They are particularly, but not exclusively, applicable to manufacturing scale processes of fabricating polymer-cased lithium-ion secondary battery cells. Briefly, the present invention provides an electrochemical cell fabrication process wherein a binder is applied to a porous battery separator material. Binder solutions in accordance with the present invention, are formulated with a low boiling/high solubility (“good”) solvent and a higher boiling/no or low solubility (“bad”) solvent to dissolve the binder and coat it on the separator. When the separator is subsequently dried by evaporation of the solvents, a porous coating of binder is formed on the separator material.

Abstract: Provided are alternative fabrication methods and compositions for an electrochemical cell. The methods and compositions of the present invention are particularly, though not exclusively, applicable to the manufacture of polymer-cased lithium-ion secondary battery cells. Briefly, the present invention provides an electrochemical cell fabrication process wherein a PVDF-based binder specifically selected for its physical and chemical properties, in particular, it's high crystallinity, is coated on a porous separator material to form a porous separator. The high crystallinity PVDF of the binder results in improved cell structure and performance.
