本発明は、蓄エネルギー機能を合わせ持った太陽電池に
関するものである。DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a solar cell that also has an energy storage function.
〈従来技術〉
近年、二次電池を用いず、太陽電池と大容量コンデンサ
のみで作動する装置又は機器の開発が進められている。<Prior Art> In recent years, the development of devices or devices that do not use secondary batteries and operate only with solar cells and large-capacity capacitors has been progressing.
これは、太陽電池のマーケットを、光がきているときの
み使用するような電卓だけでなく、二次電池を用いず安
価に蓄エネルギー機能を与えることにより、時計やポケ
コン等にまで広げられるものと期待される。This will expand the solar cell market not only to calculators that are used only when there is sunlight, but also to watches, pocket computers, etc. by providing an energy storage function at low cost without using secondary batteries. Be expected.
コンデンサーは、蓄エネルギー源として今までも考慮さ
れていたが、容量が小さいため実用にはならなかった。Capacitors have been considered as energy storage sources, but their small capacity has made them impractical.
しかし、最近の低消費電力のモーター等の技術進歩によ
シ、実用化されるようになってきている。However, due to recent technological advances in motors with low power consumption, they are now being put into practical use.
ところで、従来の装置又は機器では、太陽電池とコンデ
ンサーが全く別部品として構成され、装置又は機器内に
おいても異なった場所に配置されている。By the way, in conventional devices or devices, the solar cell and the capacitor are configured as completely separate parts, and are arranged at different locations within the device or device.
〈発明の目的〉
本発明は、太陽電池とコンデンサーを一体化し、太陽電
池自体に蓄エネルギー機能を合わせ持たせるようにする
とともに、コンデンサ誘電体およびその両電極を透明体
にして目だたず大容量にできる太陽電池を提供するもの
である。<Purpose of the Invention> The present invention integrates a solar cell and a capacitor so that the solar cell itself has an energy storage function, and also makes the capacitor dielectric and both electrodes transparent so that it can be made inconspicuous and large. The purpose is to provide a solar cell that can increase the capacity.
〈実施例〉 以下図面に従って本発明の実施例を詳細に説明する。<Example> Embodiments of the present invention will be described in detail below with reference to the drawings.

や、印刷法によるＣｄＳ太陽電池等が可能である。また
、誘電体４は透明のものであり、該部分の両電極１′も
いわゆる透明電極材料で形成されている。In Figure 1, 1 and 1' are electrodes, 2 is a thin film solar cell,
3 is a substrate, 4 is a capacitor dielectric, and the same substrate 3
A solar cell and a capacitor are arranged side by side on the top. As the thin film solar cell, an amorphous solar cell formed by the plasma C'Dv method (Chemical Hehartipositane), a CdS solar cell formed by the printing method, etc. are possible. Further, the dielectric 4 is transparent, and both electrodes 1' in this portion are also formed of a so-called transparent electrode material.

ネルギー機能を持ち、発電機能のみならず蓄エネルギー
機能を合わせ持った太陽電池が提供できる。FIG. 2 shows an equivalent circuit of the solar cell SB and the capacitor C formed on the substrate 3 of FIG. 1. By connecting a large number of these in series as shown in Figure 3 or in parallel as shown in Figure 4, and connecting the load 5, the capacitor on the board 3 can have an energy storage function, not only a power generation function. We can provide solar cells that also have an energy storage function.
ここにおいて、誘電体４および該部分の両電極１′は透
明体であり、コンデンサー自体が透明となシ、この面積
を大きくしても目だたす、容易に蓄エネルギー容量を大
きくできる。Here, the dielectric 4 and both electrodes 1' of the part are transparent, and since the capacitor itself is transparent, the energy storage capacity can be easily increased even if the area is increased.
特に時計用に用いる場合、フロントガラスのほぼ全面を

、実際の使用で中断の恐れが全くない、充分な蓄エネル
ギー容量が確保できる。Particularly when used in watches, almost the entire surface of the windshield can be used as a condenser, which is useful. An example is shown in FIG. FIG. 3(a) is a top view, and FIG. 3(b) is a cross-sectional view, in which the substrate 3 also serves as a windshield. As shown in the figure, even if the entire glass surface other than the two solar cells is used as a capacitor, it will not interfere with its use as a watch. In addition, the area of a portion of the capacitor can be increased, and a sufficient energy storage capacity can be ensured without any fear of interruption during actual use.

It is also possible to form a common transparent electrode 1'. In this case, the equivalent circuit becomes as shown in FIG. It is of course possible to connect a large number of these in parallel (the same connection form as shown in FIG. 4), but it is also possible to connect them in series as shown in FIG. Further, as shown in FIG. 9, some portions may be laminated.
これによれば、更に蓄エネルギー容量を大きくすること

Useful solar cells can be provided.
