  • CARBON NANOTUBE FILM BASED SOLAR CELL AND FABRICATING METHOD THEREOF
    Publication number: 20100078067
    Abstract: A carbon nanotube-based solar cell and fabricating method thereof are provided. The method is achieved by applying carbon nanotube film (1) photoelectric conversion material and an upper electrode simultaneously. The method improves photoelectric conversion efficiency and life time of the solar cell, the fabricating method of the solar cell is simple, and the fabricating cost is low.

  • Direct synthesis of long single-walled carbon nanotube strands
    Patent number: 7615204
    Abstract: Long, macroscopic nanotube strands or cables, up to several tens of centimeters in length, of aligned single-walled nanotubes are synthesized by the catalytic pyrolysis of n-hexane using an enhanced vertical floating catalyst CVD technique. The long strands of nanotubes assemble continuously from ropes or arrays of nanotubes, which are intrinsically long. These directly synthesized long nanotube strands or cables can be easily manipulated using macroscopic tools.
