Solar-powered generator, solar-powered watch

摘要

PROBLEM TO BE SOLVED: To improve the power generation efficiency of a solar cell 30 and to suppress deterioration of aesthetics. SOLUTION: A wristwatch 1 includes a dial 10 including a light color portion W and a dark color portion BK having a light transmittance higher than that of the light color portion W, and a light transmitted through the dial plate 10 is incident to a user. The solar cell 30 generates electric power by the incidence of the blue light component B and the green light component G rather than the generation of electric power by the incidence of the red light component R of the visible light. The power generation amount is large, and the dial plate 10 has the absorption layer 11 that absorbs the red light component R with a higher light absorption rate than the blue light component B and the green light component G in the dark color portion BK.
