A solar cell in which the P-type light absorbing layer is thin, and the nanoparticles are disposed. Although the P-type light absorbing layer is thin, the light absorption efficiency may be increased by the use of nanoparticles. Accordingly, the P-type light absorbing layer is formed thin, and thereby the material cost may be reduced and the process time may be shortened. Also, a solar cell in which the nanoparticles are disposed on the transparent electrode layer or inside the transparent electrode layer, and the size of the nanoparticles and the space between them are controlled such that the light absorption efficiency may be increased, and the nanoparticles are disposed in the N-type light absorbing layer, and the size of the nanoparticles and the space between them are controlled such that the light absorption efficiency may be increased. |
