  • Publication number: 20220149305
    Abstract: The present invention provides compositions comprising a metal oxide electrode, a passivating agent on its surface, and a hybrid organic-inorganic perovskite active layer in contact with the metal oxide electrode surface. The presence of a passivating agent on the metal oxide surface increases stability and/or photovoltaic power conversion efficiency of the electronic component comprising a composition of the invention.

  • Patent number: 9505770
    Abstract: Organic photovoltaic (OPV) devices are disclosed. An exemplary device has first and second electrodes and an organic, photovoltaically active zone located between the first and second electrodes. The photovoltaically active zone includes an organic electron-donor material and an organic electron-acceptor material. The electron-donor material includes one or more trivalent- or tetravalent-metal phthalocyanines with alkylchalcogenide ring substituents, and is soluble in at least one organic solvent. This solubility facilitates liquid-processability of the donor material, including formation of thin-films, on an unlimited scale to form planar and bulk heterojunctions in organic OPVs. These donor materials are photovoltaically active in both visible and near-IR wavelengths of light, enabling more of the solar spectrum, for example, to be applied to producing electricity. Also disclosed are methods for producing the metalated phthalocyanines and actual devices.

  • Publication number: 20010017155
    Abstract: Polymers comprising triarylamine substituent monomers. The polymers are products of anionic or radical polymerization of monovinylated triarylamine monomers or of ROMP polymerization of monomers comprising a triarylamine component, a linker component, and a cyclic olefin that is capable of undergoing a ring-opening polymerization reaction. The resulting polymers possess hole-transporting properties and are useful as hole transport layers in light-emitting diodes or as components of photorefractive materials.
