Abstract

Disclosed is an electronic apparatus including a dial plate having light transparency, a module including an antenna for receiving circularly polarized waves which is disposed below the dial plate, the antenna having a radiation electrode, and a solar panel disposed between the dial plate and the module, wherein the solar panel includes a common substrate, a plurality of solar cells disposed on the common substrate, and an inactive segment disposed on the common substrate at a place corresponding to the place of the radiation electrode.

First claim

What is claimed is:

1. An electronic apparatus comprising:
a dial plate having light transparency;
a module including an antenna for receiving circularly polarized waves which is disposed below the dial plate, the antenna having a radiation electrode; and
a solar panel disposed between the dial plate and the module,
wherein the solar panel includes:
a common substrate;
a plurality of solar cells disposed on the common substrate; and
an inactive segment disposed on the common substrate at a place corresponding to a place of the radiation electrode, and

wherein the inactive segment includes:
a non-conductive area formed of a non-conductive material, the non-conductive area being disposed over and along an outer edge of the radiation electrode; and
a dummy cell disposed inside the non-conductive area, each of the dummy cell and the solar cells comprising a laminated structure of a first electrode layer, a semiconductor layer, and a transparent electrode layer,
wherein:
the solar cells, the non-conductive area and the dummy cell are disposed on a same plane, and the solar cells, the non-conductive area, and the dummy cell each have a same height and a same thickness; and
the non-conductive area includes a substantially rectangular outer frame disposed outside an outline corresponding to the outer edge of the radiation electrode, and a substantially rectangular inner frame disposed inside the outline.

2. The electronic apparatus of claim 1 , wherein the inactive segment has a shape corresponding to a shape of the radiation electrode and is larger than the radiation electrode.

3. The electronic apparatus of claim 1 , wherein the outer frame is wider than the inner frame.

4. The electronic apparatus of claim 1 , wherein the non-conductive material of the non-conductive area covers an upper face of the dummy cell.

5. The electronic apparatus of claim 1 , wherein the inactive segment has an outer edge of a periodic pattern.
