ABSTRACT:
A fibril solar cell includes: a fiber-shaped inner core having a porous fiber composed of first carbon nanotubes and a cathode material, in which pores of the porous fiber are filled with second carbon nanotubes, titanium dioxide, a photosensitive dye, and an electron transfer electrolyte; a photoconductive layer formed on a surface of the fiber-shaped inner core and composed of at least one photoconductive polymer; a transparent electrode layer formed on a surface of the photoconductive layer; and a transparent protective layer formed on a surface of the transparent electrode layer and composed of at least one transparent polymer. The fibril solar cell can be mass-produced inexpensively using a polymer. Also, the fibril solar cell has a high efficiency and can be converted into various shapes. The fibril solar cell can be attached to clothing, and be used as a portable power source for mobile electronics.
