NOVELTY - A nanocomposite (N1) comprises several nanotubes (100) arranged perpendicular to a substrate; and several nanoparticles (110) dispersed within each of the nanotubes or between adjacent ones of nanotubes.    USE - As a nanocomposite used in dye-sensitized solar cell (claimed) as well as materials for other industry sectors.    ADVANTAGE - The nanocomposite facilitates charge transfer using nanotubes. The nanocomposite also provides increased surface area of nanotubes and, in particular, nanoparticles, thus increasing the amount of dye molecules as well as other general molecules absorbed. When the nanocomposite is used in a DSSC, the nanotubes having a higher charge transfer rate than the nanoparticles can accelerate movement of electrons. In particular, nanoparticles filling the empty space within the nanotube increases the amount of dye molecules absorbed to its surface. Thus, the use of the nanocomposite in a DSSC significantly improve the energy conversion efficiency.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following    (1) a method of fabricating the nanocomposite (N1), involving forming several nanotubes perpendicular to a substrate; synthesizing several nanoparticles that will be incorporated into each of the nanotubes, where the nanoparticles have a diameter of less than an inner diameter of the nanotube or distance between two adjacent nanotubes; and disposing the nanoparticles within the nanotube or between the adjacent nanotubes; and    (2) a dye-sensitized solar cell (DSSC) comprising: a first electrode unit (20) including a nanocomposite (N1) and dye molecules absorbed on the nanocomposite; a second electrode unit (40) formed on a second substrate (30) so as to face the first electrode unit; and an electrolytic solution (80) interposed between the first and second electrode units.
