摘要： 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.

摘要： An optical cable includes optical fiber units each including a bundle of optical fibers. The optical fiber units are twisted together in an S-Z configuration in which a twisting direction of the optical fiber units is reversed at a reversal part and an adjacent reversal part adjacent to the reversal part. A twisting angle, by which the optical fiber units are twisted in a circumferential direction between the reversal part and the adjacent reversal part, is 540 degrees or greater.

摘要： An optical fiber ribbon includes five or more optical fibers disposed in a disposition direction perpendicular to a longitudinal direction of the optical fiber ribbon and connection parts disposed intermittently in the longitudinal and disposition directions. Each of the connection parts is disposed between and connects adjacent ones of the optical fibers. The optical fiber ribbon has a first high-density region and a first low-density region disposed at different positions in the longitudinal direction and a second high-density region and a second low-density region disposed at different positions in the longitudinal direction. At least two of the connection parts having different positions from each other in the longitudinal and disposition directions are disposed in the first high-density region. At least another two of the connection parts having different positions from each other in the longitudinal and disposition directions are disposed in the second high-density region.
