  • Patent number: 11854751
    Abstract: The present invention provides a light-transmitting electrode which has high electrical conductivity and high electron blocking performance. The present invention also provides a solar cell which is capable of achieving high energy conversion efficiency at low cost. The present invention provides a method for producing a light-transmitting electrode that has a light-transmitting substrate, a carbon nanotube film which is formed directly or indirectly on the light-transmitting substrate, and a metal oxide film which is formed directly on the carbon nanotube film. This production method includes vapor depositing the metal oxide film, which contains oxygen and a metal element belonging to the group 4, 5 or 6 of the periodic table, on one surface or both surfaces of the carbon nanotube film. The present invention provides a light-transmitting electrode which includes a light-transmitting substrate and a conductive carbon nanotube film that is formed directly or indirectly on the light-transmitting substrate.

  • Patent number: 9847181
    Abstract: The present invention provides: a film that comprises single-layer carbon nanotubes having shapes which enable the characteristics thereof to be sufficiently exhibited; and a process for producing the film. The film, which comprises single-layer carbon nanotubes, has portions where single-layer carbon nanotubes are densely present and portions where single-layer carbon nanotubes are sparsely present, the dense portions forming a pseudo-honeycomb structure in a surface of the film.
