    • Provided is a method of fabricating a solar cell utilizing semiconductor nanoparticles embedded in a polymer layer. The method includes: forming anodes on a substrate; a semiconductor raw material layer on the anodes; spin coating a polymer precursor layer on the semiconductor raw material layer; forming semiconductor nanoparticles from the semiconductor raw material layer while a polymer layer is formed by performing heat treatment on the polymer precursor layer, thereby forming a photoelectro-motive force layer made of the polymer layer in which the nanoparticles are embedded; and forming cathodes on the photoelectro-motive force layer. Each layer excluding electrodes and nanoparticles in a solar cell is formed of polymer with low price so that a device can be fast and simply fabricated and various nanoparticles can be formed according to a semiconductor raw material to be deposited during a solar cell fabrication process. In addition, the size and density of the nanoparticles formed according to heat treatment conditions can be easily adjusted so that efficiency of a photoelectro-motive force of the solar cell can be optimized according to an operating environment.
