JPH0273675A - Cylindrical rechargeable solar battery - Google Patents

Abstract

PURPOSE:To make an efficient rechargeable solar battery by attaching a semiconductor to become a solar battery onto the base plate of a cylindrical tube and inserting a dry cell into the inside. CONSTITUTION:A semiconductor 2 to become a solar battery is attached onto the base plate of a cylindrical tube having a plus terminal 4 whose one cross section is covered and where a round hole is opened at the center, and it is connected to +-terminals with conductive line 7, and then it is covered with surface material 3. The other cross section is closed with a cap 6 to become a minus terminal 5. That it, when a dry cell is inserted into the cylindrical tube whose surface is becoming a solar battery and the cap is closed, it becomes a rechargeable solar battery. If it is done this way, it can be utilized as a battery with the dry cell inserted, and when it is discharged it becomes a round whole face charger only by taking it out and leaving it alone under the solar light, so it can be charged under the same conditions regardless of the direction of solar light.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] Conventionally, solar cells have been used alone or attached to appliances, and their versatility as chargers has been low and installation has been complicated. In addition, some devices have an integrated structure with the dry cell battery, with a window built on the surface of the dry cell battery and a solar cell partially installed inside, but these devices cannot be used alone as a charger, and cannot be used for charging. At the time, it was inconvenient to have to always point the solar cell part toward sunlight, and when the life of the dry cell battery, which had a limited number of charging cycles, ended, the solar cell part had to be discarded along with it, which was uneconomical. .

Means to Solve the Problems This book was actually completed with the purpose of eliminating the above-mentioned drawbacks, and if we reveal its structure now, one side is covered and there is a circular hole in the center. A semiconductor 2 which will become a solar cell is mounted on the base plate 1 of a cylindrical tube having an open positive terminal 4 and connected to the 11th terminal with a conductive wire 7, and the other cross section covered with the surface material 3 is connected to a negative terminal 5. It is characterized by closing with a capro.

Function and Effect of the Invention In fact, since the structure is as described above, when a dry battery is inserted inside the cylindrical tube whose surface is a solar cell and the cap is closed, it becomes a rechargeable solar cell. Become. In this way, you can use the dry battery as a battery while it is inserted, and when it is discharged, you can simply take it out and leave it under sunlight, and it becomes a circular full charger.
Charging is possible under the same conditions regardless of the direction of the sunlight.
Furthermore, even when the dry cell battery reaches the end of its lifespan, it can be used repeatedly as a rechargeable solar cell by simply replacing it with a new one.
