Abstract: A dye-sensitized solar cell (DSC) element includes at least one DSC. The DSC includes a first base material having a transparent substrate, a second base material facing the first base material, an oxide semiconductor layer provided between the first and second base materials, and a sealing portion connecting the first and second base materials. One transparent substrate is provided for the at least one DSC, and a coating layer covering a light receiving surface, which is opposite to the second base material, of the transparent substrate and transmitting light is provided on the first base material. The coating layer includes an annular peripheral portion, and a center portion provided at the inner side of the peripheral portion. An average thickness of the peripheral portion is smaller than a maximum thickness of the center portion, and the coating layer has a refractive index higher than that of the transparent substrate.

Abstract: A photoelectric conversion element has a photoelectric conversion cell. The cell includes a first base material having a transparent substrate, a second base material facing the first base material, and an oxide semiconductor layer provided between the first base material and the second base material. The cell has a sealing portion that connects the first base material and the second base material of the cell to each other, and the sealing portion has a first sealing portion provided between the first base material and the second base material. The first sealing portion has an annular outer sealing portion, and an inner sealing portion provided inside the outer sealing portion to form cell spaces, the number of which is the same as the number of cells. Further, a thickness of the outer sealing portion is larger than a thickness of the inner sealing portion.
