摘要:
The subject of the invention is a process for manufacturing an organic light-emitting diode device comprising at least one electrode based on an electrically conductive thin-film multilayer deposited on a substrate, in which the deposition of said multilayer comprises the following steps: a thin-film multilayer comprising at least one thin silver film between at least two thin films is deposited on said at least one face of said substrate; and the at least one coated face is heat treated using at least one source of laser radiation emitted at at least one wavelength lying between 500 and 2000 nm so that the sheet resistance of the multilayer decreases by at least 5%.
摘要:
A method for fabricating a textured single crystal including depositing pads made of metal on a surface of a single crystal. A protective layer is deposited on the pads and on the single crystal between the pads; and etching the surface with a first compound that etches the metal more rapidly than the protective layer is carried out. Processing continues with etching the surface with a second compound that etches the single crystal more rapidly than the protective layer; and etching the surface with a third compound that etches the protective layer more rapidly than the single crystal. The textured substrate may be used for the epitaxial growth of GaN, AlN or III-N compounds (i.e. a nitride of a metal the positive ion of which carries a +3 positive charge) in the context of the fabrication of LEDs, electronic components or solar cells.

The subject of the invention is a substrate that can be used as a substrate for the epitaxial growth of layers based on gallium nitride and comprising a support material (11, 21) coated on at least one of its faces with at least one multilayered stack comprising at least one zinc-oxide-based layer (13, 24). The substrate is coated with a semiconductor structure of III-N or II-VI type, and it is characterized in that placed between the support material (11, 21) and said at least one zinc-oxide-based layer (13, 24) is at least one intermediate layer (12, 23) comprising oxides with at least two elements chosen from tin (Sn), zinc (Zn), indium (In), gallium (Ga) and antimony (Sb).
摘要:
A solar module is described. The solar module has a laminated composite of two substrates bonded to one another by at least one bonding layer, between which substrates there are solar cells which are connected in series and which each have an absorber zone made of a semiconducting material between a front electrode arranged on a light entrance side of the absorber zone and a rear electrode. A diffusion barrier differing from the front electrode is located between each absorber zone and the bonding layer and is designed to inhibit the diffusion of water molecules from the bonding layer into the absorber zone and/or the diffusion of dopant ions from the absorber zone into the bonding layer. A process for producing such a solar module is also described.

This layered element, in particular for a photovoltaic device, includes a polymer layer, a moisture-sensitive layer, and a protective coating forming a moisture barrier inserted between the polymer layer and the moisture-sensitive layer. The protective coating includes an antireflection multilayer comprising at least two thin layers differing in refractive index from each other.

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.

摘要:
A substrate carrying an OLED electrode, with a sheet resistance of less than 25 Ω/square, includes an electrically conducting coating, an essentially inorganic thin electrically conducting layer which is a work-function-matching layer and which exhibits a sheet resistance at least 20 times greater than the sheet resistance of the electrically conducting coating, with a thickness of at most 60 nm, and, between the electrically conducting coating and the work-function-matching layer, a thin buffer layer, which is essentially inorganic and which has a surface resistivity within a range from 10−6 to 1 Ω·cm2.
