CARBON NANOTUBE ELECTRODE HEAT-TREATED AFTER COATING AND DYE-SENSITIZED SOLAR CELL USING SUCH ELECTRODE

摘要

A carbon nanotube electrode experienced in a post heat treatment and a dye-sensitized solar cell using the same are provided to improve adhesive power with respect to a substrate and necking characteristics between carbon nanotubes by using the carbon nanotubes and a corporate body. A dye-sensitized solar cell consists of an upper transparent substrate(101), a conductive transparent electrode(102) formed on an inner surface of the upper transparent substrate, a porous negative electrode(103) of an oxide semiconductor formed on the conductive transparent electrode, relative electrodes(105,106) formed on a lower substrate in the form of a thin or thick film as an anode corresponding to the negative electrode, and an electrolyte(104) filled between the negative electrode and the relative electrodes. The relative electrode is made of a carbon nanotube electrode. The carbon nanotube electrode consists of a substrate, a carbon nanotube, and a corporate body. The carbon nanotube is dried. Thereafter, a post heat treatment is performed on the carbon nanotube. A post heat treatment temperature is selected form a temperature range within which a carbonization of the corporate body is proceeded.
