Abstract

PURPOSE:To obtain a solar cell which can be utilized for a suntracking apparatus or the like by a method wherein two pieces or two sets of solar cells are connected in series, both ends are short-circuited and a load is connected to both ends of the solar cells so that its polarity can be changed according to how the cells are exposed to light. CONSTITUTION:Two pieces or two sets of solar cells 1, 2 of a nearly identical characteristic are connected in series; both ends are short-circuited; they are used by connecting an electrical load 3 to both ends of the solar cells 1, 2. Thereby, when light is incident on only the solar cells 1, an electric current flows from the solar cell 1; since the electric current does not flow from the solar cell 2, the electric current flows to the load 3; at this time, the left side of the load 3 becomes positive and its right side becomes negative. In addition, when the light is incident on only the solar cell 2, the electric current is going to flow from the solar cell 2 and the electric current does not flow from the solar cell 1; accordingly, the electric current flows to the load 3; at this time, the right side of the load 3 becomes positive and its left side becomes negative. When the same light is incident on the solar cells 1, 2, the electric current does not flow to the load 3. Accordingly, when a direct-current motor is connected as the load 3, the solar cells can be utilized for a sun-tracking apparatus.

Description

【発明の詳細な説明】 図の様に２個または２組のほぼ同じ特性の太陽電池（１
）（２＞を直列に接続し、両端を短絡して、これに直流
モータなどの電気的負荷（３）を接続します。Detailed Description of the Invention As shown in the figure, two or two sets of solar cells (one
) (2> are connected in series, both ends are shorted, and an electrical load (3) such as a DC motor is connected to this.

太陽電池（１）（２＞の極性は図の中に＋−でボしてあ
ります。The polarities of solar cells (1) (2>) are marked with + and - in the diagram.

太陽電池に流れる電流は入射する光の量にほぼ比例する
ので（１）だけに光が入射すると（１）が電流を流そう
とする、（２）は電流を流さないので（３）に電流がな
がれる、そのとき（３）の左側が＋、右側が−となりま
す。The current that flows through a solar cell is approximately proportional to the amount of incident light, so if light is incident only on (1), (1) will cause current to flow, and (2) will not cause current to flow, so (3) will have a current flow. When the current flows, the left side of (3) becomes + and the right side becomes -.

（２）だけに光が入射すると（２）が電流を流そうとす
る、（１）は電流を流さないので（３〉に電流が流れる
、そのとき（３）の右側が＋、左側が−となり、極性が
変わった事になります。If light is incident only on (2), current will flow in (2), but since (1) does not, a current will flow in (3>). At that time, the right side of (3) is + and the left side is -. This means that the polarity has changed.

（１）（２＞に同じ光が入射すると（１）から出た電流
が（２）に入り（２）から出た電流が（１）に入るため
に（３）には電流が流れません。(1) When the same light enters (2>), the current from (1) enters (2), and the current from (2) enters (1), so no current flows to (3). .

（１）と（２）の入射する光量の差が（３）に流れる電
流の方向と大きさに変換された事になり（１）と（２）
とで一つの太陽電池と見ると、光の当り方で極性が変わ
る太陽電池となり普通の太陽電池と同じ様に電気エネル
ギーも得られます。The difference in the amount of incident light between (1) and (2) is converted into the direction and magnitude of the current flowing in (3), so (1) and (2)
If you look at it as a single solar cell, it becomes a solar cell whose polarity changes depending on how the light hits it, and it can also obtain electrical energy just like a normal solar cell.

) and (2) are arranged, a screen is placed between them, and this is placed on a rotary table with a DC motor.When this DC motor is connected as the electrical load for (3), the screen stops in the direction of the screen or the sun and tracks the sun. You can create a solar tracking device that does not require external energy to begin with.If it rotates in the opposite direction, simply reverse the connection of the DC motor to start tracking.

本発明を使用して実用的な太陽追尾装置を作るには、水
平方向だけでなく垂直方向の追尾装置を組合わせる必要
が有りますが、太陽光以外の外部エネルギーが必要熱い
ため、はとんどランニングコストが掛からず、従来の太
陽追尾装置には見られない長所が有ります。In order to create a practical solar tracking device using the present invention, it is necessary to combine not only horizontal but also vertical tracking devices, but this is difficult because external energy other than sunlight is required and hot. It has advantages not found in conventional solar tracking devices, such as low running costs.

追尾精度は１度以下にする事も可能で、今後の太陽エネ
ルギー開発の有力な道具となるのではないかと思ってい
ます。It is possible to reduce the tracking accuracy to less than 1 degree, and I think it will become a powerful tool for future solar energy development.
