Because it is noiseless and uses lean energy, applications have been devised in a variety of fields, from electrical products such as watches and calculators to unmanned radio repeaters, power generation systems on the roofs of houses, and large-scale power generation systems. There is. On the other hand, an electronic device with a solar cell that uses a solar cell as a power source and as an optical information input element is disclosed in Japanese Patent Laid-Open No. 154562/1983. [This name] was a solar cell used in small electronic devices such as electronic desktop calculators, which had a power generation function as well as an optical signal reception function, adding the ability to receive information by light. FIG. 2 shows a schematic equivalent circuit diagram of a conventional example of a solar cell panel having an optical signal receiving function. In the solar cell panel 203 shown in the figure, the solar cell 101 receives sunlight 102, and the generated energy is stored in the storage battery B1. Furthermore, when the solar cell 101 is not generating power, the storage battery B
A backflow prevention diode D1 is connected to prevent backflow of current from the solar cell 101 to the solar cell 101. Furthermore, when the solar cell 101 receives the AC signal light 102,
Energy generated by the solar panel 203, which is connected in series with a resistor R2 for detecting this alternating current signal, is outputted through the output terminal OUT. Further, the received optical signal is output from the signal output terminal Sig. [Problem to be solved by the invention] However, when trying to receive optical signals with a general power solar cell panel that is larger than the culm with the output power, other than the small deuteron device such as the conventional example mentioned above, In this case, there were the following problems. That is, since it is necessary to detect the optical signal at the same time as outputting the electric power, as shown in FIG.
It is necessary to connect the backflow prevention diode D1, the solar cell 101, and the optical signal detection resistor R2 all in series. Therefore, there is a problem in that power loss occurs in the backflow prevention diode D1 and further in the optical signal detection resistor R2. [Object of the Invention] The object of the present invention is to solve the problems in solar cell panels that are equipped with the optical signal reception function as well as the conventional photovoltaic power generation function as described above, and to simultaneously perform photovoltaic power generation and optical signal 15 reception. In addition, it is possible to realize a solar cell panel that also serves as an optical No. 43 receiver and has even less power loss. [Means and effects for solving the problems] The present inventors aimed to overcome the above-mentioned problems encountered in conventional solar cell panels that also serve as optical signal receivers, and to achieve the above-mentioned objects of the present invention. After extensive research, they discovered that power loss can be reduced by configuring the solar cell's backflow prevention diode to also function as a resistor for detecting optical signals. Furthermore, the present inventor has provided a method for transmitting the signal voltage detected by the reverse current prevention diode to an R
C circuit, only the alternating current component is separated, and the separated alternating current component is further amplified by an amplifier built in the solar cell and powered by the output of the solar cell panel. We found that by doing this, it is possible to obtain a signal with less noise. That is, the present invention, as a means for solving the above-mentioned problems, includes a solar cell, a storage battery that stores the energy generated by the solar cell, and a backflow prevention guide connected in series with the solar cell and the storage battery. Solar power di with optical signal receiving function
! The panel has an optical signal receiving function characterized in that the backflow prevention diode doubles as an optical signal detection resistor by utilizing a voltage drop in the backflow prevention diode to separate the optical signals. It provides solar cell panels. Also, a solar cell, an R battery that stores energy generated by the solar cell, a backflow prevention diode connected in series to the solar cell and the storage battery, and an output terminal for connecting the solar cell and the storage battery to a load. an RC circuit for separating a direct current component and an alternating current component of the power generated by the solar cell; and an amplifier that is operated by being supplied with power from the output terminal and amplifies the separated alternating current component; The above problem is solved by a solar cell panel having an optical signal receiving function characterized in that the voltage drop in the reverse current prevention diode is guided to the front 2Re circuit (thereby separating the DC component and the AC component). Hereinafter, the means of the present invention will be explained in more detail with reference to the embodiments shown in the drawings, but the present invention is not limited thereto in any way. Fig. 1 shows the optical signal receiving function of the present invention. 1 is a schematic equivalent circuit diagram showing an example of a solar cell panel with a solar cell panel 103. In a solar cell panel 103 shown in the figure, a solar cell 101 receives sunlight 102, and the generated energy is stored in a storage battery Bl. A backflow prevention diode Di is connected to prevent current from flowing backward from the storage battery B1 to the solar cell 101 when the battery 101 is not generating power. In this case, the reverse current prevention diode also serves as a resistor for detecting this alternating current signal.The signal detected by the reverse current prevention diode is further connected to an RC circuit (R1,
Only the AC component is separated by C1). Furthermore, this AC signal is connected to an amplifier Al, amplified, and outputted to a signal output terminal Sig. Further, the amplifier A1 is supplied with the output of the solar panel as a power source. As described above, according to the present invention, the conventional optical signal detection resistor R2 can be omitted, thereby reducing power loss. By incorporating an amplifier, a more accurate optical signal can be detected.Furthermore, by using the power generated by a solar cell as a power source for the amplifier, an amplifier with less noise can be obtained. The solar cell of the above device provided by
It may be a unit cell or multiple cells connected in series or parallel, and any type of solar cell may be used as long as it has the ability to generate electricity from sunlight and receive signal light. Examples of such solar cells include monocrystalline silicon solar cells, Examples include batteries, polycrystalline silicon solar cells, amorphous silicon solar cells, compound semiconductor solar cells, and the like. Further, - the storage battery provided by the present invention may be any type as long as it can store the output of a solar cell, such as a lead acid battery, a nickel-cadmium storage battery, etc. [Example J Below, the present invention will be further explained by describing examples of the solar cell panel of the present invention, but the present invention is not limited thereto. (Example 1) FIG. 1 shows a schematic equivalent circuit of a solar cell panel having an optical signal receiving function according to the present invention. In the figure, an amorphous silicon solar cell (30x60cm" 10W) is used as the solar cell 101, and a lead acid battery (12V, 200Wh) is used as the storage battery B1.
was used. The load is a night light (10W fluorescent light)
Output terminal OU for an electronic clock (power consumption 10mW)
Attached to T. A personal computer having an I10 interface with an A/D converter was connected to the signal output terminal Sig. The solar cell panel 103 of this embodiment configured in this way is
It was installed on the roof of a house on a midsummer day. 10 solar cells during the day
The electric power generated in step 1 was supplied to the above-mentioned clock, and the surplus electric power was stored in the storage battery B1. At this time, the maximum output of the solar panel 103 is 15V, 0
．． It was 6A. Also, the amount of electricity generated on day 1 was approximately 25 watt hours, of which the electricity consumed by the clock was negligibly small compared to the electricity stored in battery B1, and most of the electricity was stored in battery B1. . Furthermore, since the solar cell 101 does not generate electricity at night, power is supplied to the load by the storage battery B1, and the clock can be illuminated for about 3 hours at night. On the other hand, when the solar cell panel was irradiated with sunlight 102, signal light was also irradiated at the same time to test whether the optical signal could be received by a personal computer. A 3 mW helium neon laser is used as the light source of the optical signal, and it is installed at a distance of 300 m from the solar panel, and this signal light is modulated into a pulse code using a liquid crystal shutter. This signal light is irradiated onto the solar panel 103. The signal received by the solar cell 101 is sent to the signal output terminal Si.
n and transmitted to a personal computer via an I10 interface. As a result, the signals transmitted by the helium-neon laser could be faithfully received by the personal computer. (Example 2) In this example, in the device having the schematic equivalent circuit shown in FIG. 1, the light receiving area of the solar cell panel 103 was increased three times, and the output of the solar cell 101 was set to 15 V and 1.8 A. According to this, the capacity of storage battery B1 is also 12V, 600V.
I installed the one from Wh. As a load, a night illuminator (
Electronic clock with 10W T-ED (power consumption 10m)
W) was attached to the output terminal 0tJT. Signal output terminal S
The same one as in Example 1 was attached to the ig. The device of this embodiment configured in this way was installed and put on the roof of a house on a summer day in summer. was stored in storage battery B1. At this time, the maximum output of the solar panel 103 is 15V
, 1.8A. Furthermore, the mW power generated per day is approximately 75 watt hours, of which the power consumed by the clock is negligibly small compared to the power stored in storage battery B1, and most of the power is stored in storage battery B1. . Also, since the solar cell 101 does not generate electricity at night, power is supplied to the load 4:! [8 Pond B1 was used, and the clock was illuminated for about 9 hours at night. On the other hand, when the solar cell panel 103 was irradiated with sunlight 102, signal light was also irradiated at the same time to test whether the optical signal could be received by a personal computer. As a light source for the optical signal, a 10 mW argon ion 1/
- It was installed at a location 1 km away from the solar cell panel 103 and modulated into a pulse code using a liquid crystal shutter. This signal light was irradiated onto the solar cell panel 103, and the signal received by the solar cell 101 was transmitted to the personal computer via the I10 interface. As a result, the signals transmitted by the argon ion generator could be faithfully received by the personal computer. (Example 3) In this example, the amorphous silicon solar cell 101 shown in Example 2 was replaced with a polycrystalline silicon solar cell, and the other configurations were the same as in Example 2. Loads and information equipment similar to those in Example 2 were connected to the device of this example, and power generation during the day and lighting and reception of optical signals at night were performed. As a result, in this example as well, sufficient electromotive force could be obtained from the solar cell, and the signal transmitted by the argon ion laser could be faithfully reproduced by the personal computer. [Effect of the invention 1] As is clear from the above embodiments, the solar cell panel having an optical signal receiving function of the present invention replaces the conventionally installed backflow prevention dice with a resistor for separating AC signals. Because it is used as a device, it has a simple structure, fewer failures, and can be provided at low cost. Furthermore, compared to a conventional solar cell panel in which a resistor for optical signal detection is connected in series with a backflow prevention diode, the number of elements connected in series is reduced, so power loss can be reduced. Furthermore, since an amplifier for amplifying alternating current signals is built into the panel, and the power supply to the amplifier is connected from the output of the solar panel, problems caused by noise from the power supply etc. can be reduced.
