  • Patent number: 9400441
    Abstract: Embodiments pertain to a method of creating an electrostatic latent image through use of an electrostatic latent image generating device comprising a single exposing device for selectively exposing a surface of the electrostatic imaging member to light, and a single electrostatic charging device for charging the surface of the electrostatic imaging member, wherein the exposing device is located before the electrostatic charging device such that the exposing the surface of the electrostatic imaging member to light precedes the charging the surface of the electrostatic imaging member and wherein charge is not accepted by the exposed surface of the electrostatic imaging member and the charge is accepted by the unexposed surface of the electrostatic imaging member.

  • Publication number: 20160091805
    Abstract: A method of forming an overcoat layer. The method comprises providing a substrate having an imaging structure formed thereon, the imaging structure comprising (i) a charge transport layer and a charge generating layer, or (ii) an imaging layer comprising both charge generating material and charge transport material. An overcoat composition is deposited on the imaging structure, the overcoat composition comprising a charge transport molecule, a fluorinated building block, a leveling agent, a liquid carrier and optionally a first catalyst. The fluorinated building block is a fluorinated alkyl monomer substituted at the ? and ? positions with a hydroxyl, carboxyl, carbonyl or aldehyde functional group or the anhydrides of any of those functional groups. The overcoat composition is cured to form an overcoat layer that is a fluorinated structured organic film, the curing comprising treating an outer surface of the overcoat composition with at least one cross-linking process.

  • Patent number: 9012772
    Abstract: A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, and a semiconducting bilayer. The bilayer is composed of a first continuous sublayer and a second continuous sublayer. The first sublayer includes a first polymorph of a metallophthalocyanine. The second sublayer includes a second polymorph of the same metallophthalocyanine. The complementary absorption profiles of the polymorphs result in a device having greater absorption and efficiency, improving performace of the photovoltaic device.

  • Patent number: 8962994
    Abstract: A photovoltaic device is disclosed. The photovoltaic device includes a substrate, an anode, a cathode, two semiconducting layers, and an electron transporting layer. The first semiconducting layer comprises a first metallophthalocyanine. The second semiconducting layer includes a blend of a second metallophthalocyanine with an electron acceptor. The second semiconducting layer is located between the first semiconducting layer and the electron transporting layer. The first and second metallophthalocyanines have different valences. The complementary absorption profiles of these layers result in a device having greater absorption and efficiency than expected, without the need for a recombination layer or the need to match current between layers.
