Abstract

Official abstract text for this publication.

A watch includes a case, and a solar cell disposed inside the case and including a substrate made of resin and having a surface, a power generating unit having, at the surface, a first electrode, a first semiconductor layer, and a second electrode that are stacked in order, a first antenna including a third electrode that is provided at the surface and that is disposed at a position not to overlap the power generating unit in a plan view viewed in a direction orthogonal to the surface, and a protective layer disposed covering the power generating unit and the first antenna.

First claim

Opening claim text (preview).

What is claimed is: 1. A watch comprising: a case; and a solar cell disposed inside the case and including: a substrate made of resin and having a surface; a power generating unit having, at the surface, a first electrode, a first semiconductor layer, and a second electrode that are stacked in order; a first antenna including a third electrode, provided at the surface and disposed at a position so as not to overlap the power generating unit; and a protective layer disposed covering the power generating unit and the first antenna. 2. The watch according to claim 1 , wherein the first electrode and the third electrode are disposed to at least partially overlap in a side view viewed in a direction parallel to the surface. 3. The watch according to claim 1 , wherein a second semiconductor layer is disposed between the third electrode and the protective layer. 4. The watch according to claim 3 , wherein the first semiconductor layer and the second semiconductor layer are provided integrally. 5. The watch according to claim 3 , wherein a resin layer is provided between the second semiconductor layer and the protective layer. 6. The watch according to claim 1 , comprising: a dial; and a dial ring disposed at a periphery of the dial, wherein the third electrode is disposed at a position to overlap the dial ring. 7. The watch according to claim 1 , wherein the solar cell includes a second antenna including a fourth electrode, provided at the surface and disposed at a position so as not to overlap the power generating unit and the third electrode in the plan view; and the protective layer is disposed covering the power generating unit, the first antenna, and the second antenna. 8. The watch according to claim 1 , wherein the first antenna is disposed between the power generating unit and the case in the plan view. 9. The watch according to claim 1 , wherein the case includes metal.
