Description of the Related Art A solar cell for converting sunlight energy into electric energy is used as a power supply device for a flying object such as an artificial satellite in outer space. However, in this solar battery, a magnetic moment is generated by the current loop generated by the solar battery cell, and this magnetic moment may adversely affect the operation of the artificial satellite. For example, when measuring the magnetic field distribution of the earth and other planets with a scientific satellite, the magnetic moment generated by the solar cell mounted on the satellite has a great influence on the measurement accuracy. Also,
Support plate supporting the solar cells (substrate)
Or, when a cosmic particle beam is projected onto a wire connected to a solar battery cell, these are charged up, which also causes a magnetic field to be generated.

It is an expanded sectional view which follows the -A line. In these figures,
A large number of solar battery cells 3 are arranged on the surface of a substrate 1 having a honeycomb structure and are bonded by an adhesive 4 to form a solar battery panel. The solar cells 3 are electrically connected to each other by the conductive connecting fittings 5, and the ends thereof are connected to the load circuit (not shown) by the wires 6. Then, a cover glass 8 having a conductive film 8a coated on the surface thereof is adhered to the surface of the solar battery cell 3, and the conductive film 8a of each cover glass 8 is connected to each other by a conductive connecting wire 9. Further, the back surface of the substrate 1 is coated with a conductive paint 12.

However, it is not possible to prevent the wire rod 6 exposed on the back surface of the substrate 1 from being charged up, and this causes a magnetic field. In addition, solar cell 3
As shown in FIG. 3, by arranging so that the directions of the currents flowing in the solar cell rows are opposite to each other between the adjacent solar cell rows, the magnetic moment generated by the current loop is reduced. Although suppressed, it is difficult to completely eliminate this magnetic moment due to variations in the output characteristics of the solar cells and restrictions on the arrangement of the solar cells due to the substrate shape.

This is disclosed in Japanese Patent Laid-Open No. 3-104174, and its essential part is shown in FIG. In the figure, the same parts as those in FIG. 4 are designated by the same reference numerals. In this structure, the insulating film 2a is provided between the back surface of the solar cell 3 and the front surface of the substrate 1 along the row of the solar cell 3.
The conductor path 2 is extended through the conductor path 2, and a current is passed through the conductor path 2 in a direction opposite to the current flowing through the solar cell 3. With such a configuration, even if the output characteristics of the solar battery cells 3 vary, or even if the arrangement of the solar battery cells is restricted by the shape of the solar battery panel, the occurrence of a current loop is suppressed. However, the magnetic moment can be effectively prevented.

Since part of the wire is exposed, it is impossible to prevent the wire rod 6 and the substrate 1 from being charged up by the cosmic particle beam, and it is difficult to completely prevent the generation of the magnetic field. For this problem, for example, it is possible to apply a conductive paint to the back side of the substrate so as to include the wire, but at the time of application, pretreatment and preparation to prevent damage to the solar cells and surface contamination Enormous cost and time are required. In addition, the resistance value of the formed conductive paint film may become non-uniform, resulting in variations. Furthermore, the conductive paints that can be used are limited, and the photovoltaic cells are used with reduced light-electricity conversion efficiency. In particular, since there is only black paint in this kind of conductive paint, when this paint is used, it absorbs solar heat and raises the temperature, and the conversion efficiency of the solar cell depending on the temperature becomes low. Also occurs. The purpose of the present invention is to
While suppressing the magnetic moment due to the current loop,
It is an object of the present invention to provide a solar cell power supply device capable of reliably preventing generation of a magnetic field due to charge-up.

を向上することも可能となる。As described above, according to the present invention, since the conductor path for flowing the current in the direction opposite to the direction of the current flowing through the solar cells arranged on the surface of the substrate is provided, the solar cells flow through the solar cells. The magnetic moments generated by the electric current and the electric current flowing through the conductor path are canceled. Also,
A cover glass having a conductive film is provided on the front surface of the solar cell, and a back surface of the substrate has a conductive film on the front surface so as to cover a conductive path that allows a current generated in the solar cell to flow to a load. By providing the covering film, the charge up of the cosmic particle beam to the solar cell and the conductor path is prevented, and the generation of the magnetic field is prevented. This prevents generation of a magnetic field in the solar battery power supply device, and enables highly accurate measurement even when measuring the magnetic field distribution of the earth or other planets with a scientific satellite, for example. Also,
A thin solar cell panel, that is, a solar cell power supply device can be configured by forming the conductor path with a printed circuit formed on the front surface of the substrate and forming the conductive path with a printed circuit formed on the back surface of the substrate. . Furthermore, by forming the coating film flat on the back surface of the substrate, the ratio of the solar absorptivity to the infrared emissivity is reduced, the temperature rise of the solar cells is suppressed, and the photoelectric conversion of the solar cells is performed. It is also possible to improve efficiency.
