Carbon Nanotubes Tungsten Trioxide Thin Film Producing Method

Carbon nanotubes tungsten trioxide film, the preparation method and application in solar cells are belong to the technical field of nano materials. The composite film is made by interspersed net carbon nanotube film and tungsten trioxide. On the one hand, the carbon nanotubes tungsten trioxide is more stable after weaving, and it can realize directly transfer, which can avoid the introduction in the process of traditional tungsten trioxide transfer. On the other hand, carbon nanotube tungsten trioxide is simpler than tungsten trioxide; it has better conductivity and higher conversion efficiency.

Chemical vapor deposition process (CVD), refers to the reaction mixture containing the desired vapor and gaseous elements, introducing the film liquid reactant or other gases introduced into the reaction chamber. Many films were prepared by using the CVD method in VLSI The deposition temperature is low, it is easy to control the film composition, film thickness and deposition time proportional, uniformity, repeatability, excellent step coverage. We prepare the tungsten coating by physical or chemical vapor deposition method at present, or improve the coating properties of tungsten by vapor deposition method in combination with other preparation techniques.

We prepare carbon nanotube film tungsten trioxide by taking ordered or disordered carbon nanotube film as a template and taking an organic metal compound as tungsten source in the presence or absence of a substrate supporting the presence of a base. The next step in the formation of a low temperature crystal is forming the size, orientation degree and thickness of tungsten oxide nanotubes controlled film. Carbon nanotube film tungsten trioxide has more flexibility and good light transmittance by comparing with the traditional materials.
