Method of producing dye-sensitized solar cell and an electrode of a dye-sensitized solar cell

A method of producing an electrode of a dye-sensitized solar cell, the method comprising:

• dispersing a plurality of semiconductor nanoparticles on a transparent electrically conductive substrate;
• dispersing a plurality of semiconductor nanofibers on the semiconductor nanoparticle layer;
• adsorbing onto all sides of the semiconductor nanofibers a first light absorption material, thereby sensitizing the semiconductor nanofibers, wherein the light absorption material has a first light absorption bandwidth and an energy level higher than that of a conduction band of the semiconductor nanofibers;
• and
• depositing additional light absorption materials, successively, and forming a shell structure, with each successively deposited light absorption material being deposited on a previously deposited light absorption material, each successively deposited light absorption material having a higher energy level than the light absorption material previously deposited.
