電に伴う銀の析出、である。The present invention provides a photoacid storage battery using silver halide, in which a thin film of lead halide is provided between the silver halide and the halogen trapping electrode to prevent the diffusion of silver ions and to allow the halogen to easily pass through. This is the precipitation of silver that accompanies the charging and discharging of photovoltaic batteries.

６０−１７０１７３号などに例がある。[Prior art] - Photoaccumulators that utilize the photosensitivity and ionic conductivity of silver halide have conventionally been made of a glass substrate made of oxides such as indium tin oxide and thin silver that transmits several hundred lights. It is formed of a transparent electrode, a silver halide such as silver bromoiodide, and a halogen trapping electrode such as carbon, for example, as disclosed in JP-A-60-170173.
このハロゲン化銀を利用した光蓄電池は充放電にともな
う銀の析出、拡散に際し、短絡を生じ、起電力を発生し
なくなることがあるという問題点があった。Photoaccumulative batteries using silver halide have a problem in that short circuits may occur when silver is deposited and diffused during charging and discharging, resulting in no electromotive force being generated.

以下、本発明の実施例に基づいて説明する。 Hereinafter, the present invention will be explained based on examples.

を形成した。As shown in the figure, an indium tin oxide transparent electrode of about 200 people was deposited on a transparent glass substrate 1 using a 2° evaporation method using the Svafuta method.
50 transparent silver layers 3. 1-AgBr layer 4 by vapor deposition method

was formed.
これに炭素繊維の表面にペリレンを溶媒により付着させ
ハロゲン捕捉電極６を形成した。Perylene was attached to the surface of the carbon fiber using a solvent to form a halogen trapping electrode 6.
更にこれに集電極及びリード端子を取り付け、封止をし
て蓄電池として完成される。Furthermore, a collector electrode and lead terminals are attached to this, and it is sealed to complete the storage battery.
上記のようにして製作したハロゲン化銀光蓄電池を性能

とで２にΩの負荷を加えたところ、最高０．７２ Ｖの
電圧が得られ、長時間の充放電作動でも性能低下は認め
られなかった。To measure the performance of the silver halide photoelectric storage battery manufactured as described above, a load of Ω was applied to 2 under an illuminance of 5000 lux using a 100W mercury lamp, and a maximum voltage of 0.72 V was obtained. No deterioration in performance was observed even after charging and discharging for hours.
一方、比較のため、ｐｂＢｒｚ層のないハロゲン化眼光

。On the other hand, for comparison, a halogenated ophthalmic photovoltaic battery without a pbBrz layer was manufactured in the same manner as above, and its performance was measured in the same manner. A maximum voltage of 0.72V was obtained, but the voltage decreased over time. It became Ov. This is because a short circuit occurred due to silver precipitation and diffusion during charging and discharging.

ほとんどみられない。On the other hand, if a PbBr layer is formed between the AgBr layer and the halogen trapping electrode as in the present invention, short circuits caused by silver precipitation and diffusion during charging and discharging can be prevented, and halogen easily diffuses through the pbBrt layer. There is almost no deterioration in performance.

This makes it possible to obtain a halogenated ophthalmic storage battery with high performance.
