However, in the above-mentioned conventional technology, solar cells are formed on a glass substrate, and the glass substrate easily breaks when subjected to impact, making it necessary to discard thin-film solar cells, which is expensive in terms of manufacturing and after-sales service. It was something. Also, if the glass substrate is thin, it will easily break when handled, so at least 0.4
A thickness of mm or more is required, and when placed above the dial, the total thickness of the watch becomes quite thick due to the thickness of the glass substrate itself.
そこで、本考案はこのような問題点を解決する

FIG. 1 is a sectional view of essential parts in an embodiment of the present invention, in which 5 is the side body of the watch, 6 is the cover glass, 7 is the back cover, and the thin film solar cell 1 is on the light-receiving surface side, that is, the substrate. It is formed on the upper surface of 2. The substrate 2 is placed on the upper surface of the lower dial plate 4, and above the dial upper layer 3, which is made of a surface-treated synthetic resin or the like and has good light transmittance, is placed so as to cover the entire surface of the substrate 2 and the lower dial plate 4. Attach it and configure the dial. Here, conventional thin film solar cells have a single color and a single finish, but by applying the dial top layer 3 on the top surface, the solar cell part can take on various finishes and colors depending on the combination with the dial top layer 3. In addition, what used to be a two-dimensional border between the solar cell and the bottom of the dial can now be seen as an integrated dial with no boundaries when viewed through the top layer of the dial. Design variations can be made freely even with a dial equipped with a solar battery. Here, an example of the dial top layer is an ultraviolet curable resin. With the ultraviolet curing type, the finish and pattern on the top surface can be processed by transfer, so various finishes can be easily applied, and the appearance of the solar cell can also be varied. It is also possible to plant plants on the top surface, or to apply plating/painting, etc., and various combinations are possible, such as making the solar cell part transparent and plating the other parts.

る。 Furthermore, since the solar cells are formed on the light-receiving surface side of the thin-film solar cell substrate, the substrate may be opaque;
It is possible to use a wide range of solar cell substrates, such as stainless steel substrates and polyimide substrates.If a stainless steel substrate is used, it is thin and unbreakable, and the thickness can be reduced.
Since it is possible to make a solar cell watch with a thickness of about 0.1 mm, it is possible to obtain a solar cell phone watch with a thickness that is unprecedentedly thin.

れる。 In FIG. 3, a substrate on which a thin-film solar cell 1 is formed is placed on the lower surface of the lower dial plate, and a dial upper surface layer with good light transparency made of surface-treated synthetic resin or the like is placed above it. It makes up the dial. A similar effect can be obtained by arranging the substrate on the lower surface of the lower dial plate.

As described above, according to the present invention, the thin-film solar cell is formed on a substrate made of stainless steel, so its strength is higher than that of the conventional technology in which the thin-film solar cell is formed on a glass substrate, for example. This means that there is no risk of damage due to external forces such as impact, and that the surface of the thin-film solar cell is protected by the top layer of the dial and the bottom layer of the dial. Since it is reinforced with a thin-film solar cell, it is possible to avoid damage to expensive thin-film solar cells, which improves manufacturing yields and eliminates the need to incur replacement costs in the event of damage, which is the case with conventional technology. This also has the effect of significantly reducing costs.

拡大できるという効果も有する。 In addition, since the upper surface layer of the dial is made of an ultraviolet curable resin that is light-transmissive, it ensures that light is received by the thin-film solar cell, and the layer on the light-receiving side of the ultraviolet curable resin is formed by transfer. The structure has a pattern and a surface treatment layer formed by plating, painting, etc., so for example, the surface of the top layer of the dial has the excellent moldability of ultraviolet curable resin and quick drying properties due to ultraviolet irradiation. By combining the various patterns formed by transfer and the various color tones of surface treatments such as plating and painting, the appearance of the dial plate can be greatly diversified and the design variations can be expanded.
