Abstract
The invention relates to a dye-sensitized solar cell and a module using the same and more particularly, to a dye-sensitized solar cell in which a photoelectrode substrate and a catalyst electrode substrate are spaced apart from each other by a separating space and coupled together by an encapsulating material and the separating space is filled with an electrolyte, characterized in that the electrolyte contains optical beads, and a module using the same. Thus, light passing through the photoelectrode substrate is refracted or reflected by the optical beads, and irradiated onto the photoelectrode substrate, thereby to improve the efficiency of the solar cell. Particularly, the efficiency of a dye-sensitized solar cell for a BIPV system is more effectively improved, said solar cell not having a separate scattering layer for maintaining the translucency thereof. If the optical beads are colored, solar cells with a variety of colors can be obtained, which achieves an aesthetic enhancement for a building adopting the BIPV system.
