Core-shell type nanocomposites included fullerene particle, preparation method thereof, and solar cell comprising the same

摘要

The present invention relates to a core-shell structured nanocomposite comprising fullerene particles, a preparation method thereof, and a solar cell comprising the core-shell structured nanocomposite, and more specifically, provides a core-shell structured nanocomposite comprising fullerene, comprising a metal nanoparticle core and a metal oxide shell, wherein the metal oxide shell of the nanocomosite comprises fullerene particles. According to the present invention, the nanocomposite is applied to a photoactive layer of a solar cell to amplify the indicent light, thereby improving the light absorption of an organic material, and can consequently enhance the light conversion rate. In addition, electron confinement in which electrons are confined in metal of a core portion is prevented by the fullerene particles contained in a shell portion, thereby improving electrical conductivity.
