Display portion structure with solar cell, electronic device with solar cell using the same, and solar cell Watch

摘要

The present invention provides a solar cell (16) having a light receiving surface (16a) disposed in the display portion, a translucent plate (17) having a predetermined light transmittance disposed on the front side of the light receiving surface, and at least a predetermined amount of power generated by the solar cell on the back surface of the light transmitting plate A display structure with a solar cell provided with a deposited layer (20) formed in the layer. Since the deposited layer is not formed on the light receiving surface of the solar cell due to the fact that the deposited layer is formed on the back surface of the light transmitting plate, it is not necessary to consider the suitability for the light receiving surface, and it is necessary to discard or replace the solar cell by the defect of the coating layer No more. In addition, since the deposited layer is formed on the rear surface of the light transmitting plate, the incident surface of the external light becomes a smooth adhering surface to the light transmitting plate of the deposited layer, so that the light reflection quantity and the light scattering quantity in the external light incidence can be reduced, and the utilization efficiency of the external light is improved. It is possible. In addition, since the deposited layer is formed on the back surface of the translucent plate, the interference fringe (Newton ring) is formed).
