Highly-conductive, transparent and mechanically-stable metal oxide layers, are formed from nanoparticles and metal salts dispersed in organic solvent, by evaporation and sintering

Nanoparticles of one or more transparent, conductive metal oxides are dispersed in organic solvent(s). One or more soluble metal compounds are added at a mass fraction of 1-50%, based on the metal compounds and nanoparticles present. The dispersion is applied to a solid substrate as a layer.

Beschreibung
Zusammenfassung:	Nanoparticles of one or more transparent, conductive metal oxides are dispersed in organic solvent(s). One or more soluble metal compounds are added at a mass fraction of 1-50%, based on the metal compounds and nanoparticles present. The dispersion is applied to a solid substrate as a layer. Energy is introduced. This evaporates solvent from the layer and the metal compounds are converted into conductive oxides. The nanoparticles become sintered to each other and with the metal oxides in the layer. The mean nanoparticle size is up to 500-1000 nm. Further agents added to the mixture are listed in detail, and may be summarized as dispersant, film-forming and binding agents. The dispersion is applied to a substrate containing glass or plastic. Application comprises spin coating, spraying, immersion, wiping or printing. The coating thickness is 1-25 mu m. Solvent is evaporated in an oven at 20-200[deg]C. Sintering is at 200-1000[deg]C. The layer is subjected to a blanketing gas at 200-600[deg]C for between 5 minutes and 2 hours. Sintering is alternatively by irradiation with laser light. Independent claims are included for the following: (A) the transparent layer so produced; (B) an electronic component employing it; (C) a display based on the component; (D) a lighting unit based upon it; (E) and a photovoltaic component. Die Erfindung betrifft ein Verfahren zur Herstellung einer hoch leitfähigen, transparenten, mechanisch stabilen Schicht durch Dispersion von TCO Nanopartikeln aus transparenten leitfähigen Oxiden, zusammen mit löslichen Metallverbindungen in einem organischen Lösemittel, der Auftragung dieser Dispersion auf ein festes Substrat und der anschließenden Umwandlung der Metallverbindungen in leitende Metalloxide, Sinterung der TCO Nanopartikel bei erhöhter Temperatur sowie durch dieses Verfahren erhältliche Schichten, elektronische Bauteile, Displays und photovoltaische Elemente, die diese Schichten enthalten.
