Abstract: A heating device equipped with a chamber defining a cavity, includes a door or wall incorporating a multiple glazing, the glazing including at least one transparent substrate coated on each face with a stack of thin layers, namely: on a first face, turned toward the cavity, a first stack that reflects heat essentially by virtue of one or more functional layers based on indium tin oxide; and on the other face, turned toward the exterior of the device, a second stack that reflects heat essentially by virtue of one or more functional layers based on a metal chosen from gold or silver.

Abstract: A glazing can be used as a constituent element of a heating device or of a fireproof door. The glazing includes a transparent substrate coated with a stack of thin layers including at least one silver-based functional metal layer and an upper protective layer based on zirconium titanium oxide.

Abstract: A subject-matter of the invention is a conducting substrate (1) for a photovoltaic cell, comprising a carrier substrate (2) and an electrode coating (6) formed on the carrier substrate (2). The electrode coating (6) comprises a main molybdenum-based layer (8) formed on the carrier substrate (2), a barrier layer to selenization (10) formed on the main molybdenum-based layer (8) and, on the barrier layer to selenization (10), an upper layer (12) based on a metal M capable of forming, after sulfurization and/or selenization, an ohmic contact layer with a photoactive semiconducting material. The barrier layer to selenization (10) has a thickness of less than or equal to 50 nm, preferably of less than or equal to 30 nm, more preferably of less than or equal to 20 nm.

Abstract: A conducting substrate includes a dielectric substrate having alkali ions, an electrode coating having a molybdenum-based layer on the substrate, and a stack of several layers between the substrate and the electrode coating. The stack comprises a first layer impermeable to alkali on the substrate, a layer for retention of alkali on the first layer impermeable to alkali and made of another material, and a second layer impermeable to alkali on the layer for retention of alkali and made of a material other than the layer for retention of alkali. The ratio of the thickness of the layer for retention of alkali to the first layer impermeable to alkali is equal to 2 or more.

Abstract: An organic photovoltaic cell comprising a substrate, a first electrode formed on the substrate, an organic photoactive medium comprising an electron donor and an electron acceptor, and a second electrode comprising a conductive mesh, the first electrode being located between the substrate and the second electrode. The cell comprises an insulating mesh formed on the first electrode. The conductive mesh is formed on the insulating mesh. The insulating mesh and the conductive mesh define together apertures for receiving the photoactive medium, said apertures being able to receive the photoactive medium after the first electrode, the insulating mesh and the conductive mesh have been deposited on the substrate.
