  • Preparation of semiconductor films
    Patent number: 9117964
    Abstract: The invention relates to a preparation process for thin semiconducting inorganic films comprising various metals (Cu/In/Zn/Ga/Sn), selenium and/or sulfur. The process uses molecular precursors comprising metal complexes with oximato ligands. Copper-based chalcopyrites of the I-III-IV2-type are prepared with high purity at low temperatures under ambient conditions. The thin films can be used in photovoltaic panels (solar cells).
    Type: Grant

    Date of Patent: August 25, 2015
    Assignee: Merck Patent GmbH
    Inventors: Ranjan Deepak Deshmukh, Ralf Kuegler, Joerg J. Schneider, Rudolf Hoffmann
  • Functional material for printed electronic components
    Patent number: 8766251
    Abstract: The invention relates to a printable precursor comprising an organometallic aluminum, gallium, neodymium, ruthenium, magnesium, hafnium, zirconium, indium and/or tin complex or a mixture thereof which contains at least one ligand from the class of the oximates, for electronic components, and to a preparation process. The invention furthermore relates to corresponding printed electronic components, preferably field-effect transistors.
