  • Publication number: 20120103669
    Abstract: The present invention relates to a transparent electrode comprising an ultra thin metal conductor (2) with a thickness between 1 nm and 10 nm and a metal grid in contact with the ultra thin metal conductor (3), the metal grid comprising openings. The invention relates also to a method for its manufacture. It can be applied in, for example, optoelectronic devices. Thanks to the metal grid, the sheet resistance of the electrode can be lowered without compromising the transparency of the electrode.

  • Patent number: 8168265
    Abstract: This invention contemplates the use of laser patterning/scribing in electrochromic device manufacture, anywhere during the manufacturing process as deemed appropriate and necessary for electrochromic device manufacturability, yield and functionality, while integrating the laser scribing so as to ensure the active layers of the device are protected to ensure long term reliability. It is envisaged that the laser is used to pattern the component layers of electrochromic devices by directly removing (ablating) the material of the component layers. The invention includes a manufacturing method for an electrochromic device comprising one or more focused laser patterning steps.

  • Patent number: 8158204
    Abstract: For making ceramic or oxidic layers (CL/OL) on substrates (S), the method according to the invention therefore provides that following application (I) and drying (II) of a suitable precursor (P) the formed precursor layer (PLD) is gassed (III) with a moist reactant gas (RG) for conversion into a corresponding hydroxide or complex layer (HL) and then thermally treated (IV) for forming a ceramic or oxidic layer (CL/OL). For the alternative production of other chalcogenidic layers of increased material conversion additional gassing is carried out with a reactant gas containing chalcogen hydrogen. Metallic layers may alternatively be made by use of a reducing reactant gas. The methods in accordance with the invention may be used wherever surfaces, even those of shaded structures, must be protected or modified or provided with functional layers, particularly in solar and materials technology.
