  • Patent number: 11322632
    Abstract: An ultra-thin and highly transparent wafer-type plasmonic solar cell comprising a layer of a conductive transparent substrate, a layer of an n-type semiconductor; a layer made of metal nanoparticles selected from the group consisting of copper, gold or silver and a layer made of a p-type semiconductor; wherein the substrate, n-type semiconductor, metal nanoparticles and p-type semiconductor respectively are linked by covalent bonds by means of one or more molecular linker/linkers. A method for producing said plasmonic solar cell by self-assembly.
    Type: Grant

  • Patent number: 10074489
    Abstract: A solid or quasisolid state hole transport material (HTM) includes the following complex: in which M is copper (Cu), palladium (Pd), gold (Au), silver (Ag), nickel (Ni), vanadium (V) cobalt (Co); and each structure represents an at least 6,6? disubstituted 2,2?-bipyridine, or an at least 2,9 disubstituted 1,10-phenanthroline Electronic devices, such as solar cells can include the solid or quasisolid state HTM, in which the complex is the main hole conducting compound of the HTM.

  • Patent number: 10038150
    Abstract: The invention relates to electrochemical devices comprising complexes of cobalt comprising at least one ligand with a 5- or six membered, N-containing heteroring. The complex are useful as p- and n-dopants, as over of electrochemical devices, in particular in organic semiconductors. The complexes are further useful as over-discharge prevention and overvoltage protection agents.
