  • Patent number: 8883247
    Abstract: Fabrication of a solar cell using a printed contact mask. The contact mask may include dots formed by inkjet printing. The dots may be formed in openings between dielectric layers (e.g., polyimide). Intersections of overlapping dots may form gaps that define contact regions. The spacing of the gaps may be dictated by the alignment of nozzles that dispense the dots. Using the dots as a contact mask, an underlying dielectric layer may be etched to form the contact regions through the underlying dielectric layer. Metal contact fingers may be formed over the wafer to form electrical connections to corresponding diffusion regions through the contact regions.

  • Patent number: 8747942
    Abstract: Solar cells are provided with carbon nanotubes (CNTs) which are used: to define a micron/sub-micron geometry of the solar cells; and/or as charge transporters for efficiently removing charge carriers from the absorber layer to reduce the rate of electron-hole recombination in the absorber layer. A solar cell may comprise: a substrate; a multiplicity of areas of metal catalyst on the surface of the substrate; a multiplicity of carbon nanotube bundles formed on the multiplicity of areas of metal catalyst, each bundle including carbon nanotubes aligned roughly perpendicular to the surface of the substrate; and a photoactive solar cell layer formed over the carbon nanotube bundles and exposed surfaces of the substrate, wherein the photoactive solar cell layer is continuous over the carbon nanotube bundles and the exposed surfaces of the substrate.

  • Publication number: 20140144427
    Abstract: The invention relates to surface enhancements for composite mouldings made from polymeric materials and to the use thereof in solar systems. These solar systems may be solar reflectors for concentrating solar radiation, flexible photovoltaic composite films, or CPV (Concentrated Photovoltaics) lenses for concentrating solar radiation. The surface enhancement comprises a self-healing coating based on crosslinkable fluoropolymers, e.g. PFEVE (polyfluoroethylene alkylvinyl ethers). These coatings exhibit good optical properties, can be used in outdoor applications, more particularly in solar applications, over very long periods of time, exhibit self-cleaning properties, and in particular are self-healing in relation to mechanical damage—such as scratching.
