A dye-sensitized solar cell is provided. The solar cell includes a transparent substrate; a conductive transparent electrode formed on a surface of the transparent substrate; a metal oxide particle electrode layer in which a photosensitive dye capable of absorbing light is adsorbed; a counter electrode, and an electrolyte injected between the metal oxide particle electrode layer and the counter electrode. The metal oxide particle electrode layer comprises a first electrode layer comprising metal oxide particles and having a predetermined pattern formed thereon and a second electrode layer comprising metal oxide particles and formed on the first electrode layer. Refractive indexes of the first and second electrode layers are different from each other.
