Abstract: The present invention relates to a nonodiode having the structures of laminating metal on a semiconductor layer and laminating a p/n type organic/inorganic semiconductor layer on the metal, and to a solar cell comprising the same. According to the nanodiode of the present invention, the metal is functioned as a rear electrode of the p/n type organic/inorganic semiconductor layer (first optical absorption layer) laminated on the metal while being used as a second optical absorption layer for re-absorbing the light which is not absorbed in the first optical absorption layer. Wherein, the semiconductor layer deposited under the rear electrode efficiently collects the hot electron generated in the metal through a Schottky barrier generated between the metal which is the rear electrode and the semiconductor layer to use the principles of generating and detecting the hot electron, and the semiconductor layer finally performs the direct optical absorption, thereby maximizing the optical absorption conversion efficiency of the nanodiode.
