<p>A timepiece provided with a solar cell (8) having power generation units (39) each formed by providing, in a mutually overlapping manner, a first electrode, an optical generation layer and a second electrode in that order on a solar cell substrate (31), wherein power generated by the solar cell (8) is used for an energy source for displaying time on a time display unit consisting of a dial (14) and pointers (5, 6) or a liquid crystal display panel (50). The solar cell (8) is constituted by forming alternately power generation units (39) and transmitting portions having a large transmittance on the substrate (31) and is disposed on the visible side of the time display unit so as to overlap it, thereby ensuring a sufficient generation efficiency of the solar cell without compromise in the time display unit's visibility and restriction in timepiece's design feature.</p> |
