NOVELTY - A dye-sensitized solar cell comprises a counter electrode layer and a sealing layer which are formed between a pair of supports. At least one support is made of a light-transmitting material. The counter electrode layer has apertures. It is formed on the support made of the light-transmitting material.    USE - For use in a dye-sensitized solar cell module (claimed).    ADVANTAGE - The invention provides a high-performance dye-sensitized solar cell with suppressed decrease of fill-factor (FF), which is caused by increase of the inner resistance in series, at the time of photoelectric conversion and suppressed decrease of light reaching a photoelectric conversion layer. The counter electrode layer functions as an electrode. It has apertures to narrow an effective surface. Formation of the apertures allows light, which cannot conventionally reach the photoelectric conversion layer due to the absorption and reflection in conventional dye-sensitized solar cells, to pass through the apertures and enter. Thus, decrease of the current density to be outputted at the time of photoelectric conversion can be suppressed. Further, since incident light can sufficiently be taken in the inside of the cell through the apertures, the counter electrode layer may be opaque. Accordingly, since the thickness of the counter electrode layer can be sufficiently thickened, the electric resistance can be lowered and FF decrease can be suppressed.    DETAILED DESCRIPTION - A dye-sensitized solar cell comprises a current collector electrode layer (2), a photoelectric conversion layer (3) of a porous semiconductor layer absorbing a dye, a carrier transporting layer (4), a counter electrode layer (5), and a sealing layer (7) which are formed between a pair of supports (1, 6). At least one support is made of a light-transmitting material. The counter electrode layer has apertures. It is formed on the support made of the light-transmitting material.    An INDEPENDENT CLAIM is also included for a dye-sensitized solar cell module comprising two or more of the dye-sensitized solar cells connected in series.
