Abstract
A plurality of solar cell assembly series 9 of a solar cell panel are so arranged that any two adjacent solar cells in the plurality of solar cell assembly series 9 have a potential difference which does not exceed V volts which is a maximum output voltage of the plurality of solar cell assembly series 9. Electric discharges between any two adjacent solar cells can be prevented from occurring. Even when the output voltage of a solar cell module changes according to control by a power control circuit, electric discharges can be prevented from occurring between solar cell modules in the solar cell array in which any two adjacent solar cells in the plurality of solar cell assembly series 9 always have a potential difference which does not exceed V volts which is the maximum output voltage of the plurality of solar cell assembly series 9. In addition, the solar cell modules can be constructed of a combination of solar cell series patterns having line symmetry. In this case, while electric discharges can be prevented from occurring between any solar cells, the magnetic field caused by the solar cell circuitry can be reduced.
Description
- This application is a continuation of U.S. patent application Ser. No. 10/508,539, filed Sep. 27, 2004, which is the U.S. National Stage Application of PCT International Application No. PCT/JP04/01200, filed Feb. 5, 2004, which claims priority to Japanese Patent Application No. 2003-033735, filed Feb. 12, 2003. The entire contents of each of the above applications are incorporated herein by reference in entirety.
- The present invention relates to a solar cell panel for use in spacecrafts, such as satellites and airships. More particularly, it relates to a solar cell array and a solar cell panel structure that can prevent electrical discharges from occurring between any solar cells.
- In the past, many spacecrafts carrying a solar cell panel have been lofted into space. As spacecrafts become more sophisticated in functionality, solar cell panels which can supply high power to spacecrafts are needed. The need to raise the output voltages of solar cell panels has therefore arisen from this necessity for the supply of high power. Since the potential difference between solar cells in a solar cell panel becomes large with increase in the output voltage of the solar cell panel, an electric discharge which originates from power generated by the solar cells which is an energy source can easily occur between the solar cells.
- A prior art solar cell panel in which an insulating material, such as an RTV adhesive, is filled into the gap between solar cells in the solar cell panel and is used as an insulating barrier is known as a measure for preventing an electric discharge from occurring between the solar cells (refer to
patent reference 1, for example). - [Patent reference 1] Japanese patent application publication No. 11-274,542 (see
FIGS. 11 and 18 ) - The prior art solar cell panel in which an insulating material, such as an RTV adhesive, is placed in the gap between solar cells in the solar cell panel and is used as an insulating barrier has the following problems. The first problem is that the prior art solar cell panel increases in weight by only the weight of the adhesive which is used as the insulating barrier. The second problem is that the prior art solar cell panel increases in cost because of increase in the material cost of the adhesive which is used as the insulating barrier, the cost of installing the insulating barrier, increase in the cost of launching a rocket, and so on.
- According to
patent reference 1, since any two adjacent solar cell assembly series are so connected as to have different gradient directions in their potentials with respect to a folded connection point therebetween, any two adjacent solar cells in any two adjacent solar cell assembly series have a minimum potential difference of 0 volts at their lowermost ends and a maximum potential difference of 2V volts at their uppermost ends when each solar cell assembly series has a potential difference of V volts. The uppermost ends of any two adjacent solar cell assembly series having the maximum potential difference are at increased risk of causing electrostatic discharges. - The smaller potential difference solar cells have, the lower risk of causing electric discharges between the solar cells. When there is no insulating barrier between any solar cells, an adequate margin of safety can be provided against electric discharges if the voltages of solar cells are reduced to ½ or less of original ones, as compared with a case where an insulating barrier is provided between any solar cells (refer to paragraph number (0049) of patent reference 1). Therefore, implementation of an arrangement of solar cells which can reduce the potential difference between any two adjacent solar cells is effective in preventing electric discharges from occurring between any solar cells.
- The present invention is made in order to solve the above-mentioned problems, and it is therefore an object of the present invention to provide a solar cell panel that can prevent electric discharges from occurring between any solar cells without installing an insulating barrier in the gap between any solar cells.
- It is another object of the present invention to provide a solar cell panel in which the potential difference between any two adjacent solar cells is reduced to less than 2V volts in the prior art even when installing an insulating barrier into the gap between any two solar cells, thereby providing a more adequate margin of safety against electric discharges between solar cells as compared with prior art solar cell panels.
- In accordance with a first aspect of the present invention, there is provided a solar cell panel including: a plurality of solar cell assembly series each including a plurality of solar cells and interconnectors each for electrically connecting between two of these solar cells in series, said plurality of solar cells being arranged substantially in a line and any two of said plurality of solar cells being electrically connected in series by one of said interconnectors; an insulator on which said plurality of solar cell assembly series are arranged at predetermined gaps; and connection lines that electrically connect said plurality of adjacent solar cell assembly series so that they are connected in series, said plurality of solar cell assembly series being arranged so that they have an identical gradient direction in their potentials.
- In accordance with a second aspect of the present invention, there is provided a solar cell panel including: a plurality of solar cell assembly series each including a plurality of solar cells and interconnectors each for electrically connecting between two of these solar cells in series, said plurality of solar cells being arranged substantially in a line and any two of said plurality of solar cells being electrically connected in series by one of said interconnectors; an insulator on which said plurality of solar cell assembly series are arranged at predetermined gaps; first connection lines that electrically connect some of said plurality of solar cell assembly series so that they are connected in series so as to form a first solar cell string; and second connection lines that electrically connect remaining ones of said plurality of solar cell assembly series so that they are connected in series so as to form a second solar cell string, the solar cell assembly series of said first solar cell string and the solar cell assembly series of said second solar cell string being arranged so that they are surely adjacent to one another.
- As a result, electric discharges can be prevented from occurring between any solar cells in the solar cell panel without installing an insulating barrier into the gap between any solar cells. In addition, when installing an insulating barrier into the gap between any solar cells, a more adequate margin of safety can be provided against electric discharges between solar cells as compared with prior art solar cell panels.

FIG. 2 , eachsolar cell 2 is secured to the surface of theinsulator 1 by an adhesive 6, and thecover glass 4 is secured to the light receiving surface of eachsolar cell 2 by an adhesive 7. - In
FIGS. 1 and 2 , wiring for connecting among solar cell assembly series is not shown. -
FIG. 3 is a diagram showing the structure of solar cell circuitry according toembodiment 1 of the present invention. - In
FIG. 3 , nsolar cell assemblies 8 each having a maximum output voltage u are arranged substantially in a line so that each solar cell assembly series 9 is constructed. Each solar cell assembly series 9 has a maximum output voltage V=n*u. Furthermore, N solar cell assembly series 9 are electrically connected in series by way ofconnection lines 10 so that asolar cell string 11 is constructed. Thesolar cell string 11 has a maximum output voltage V1=N*V equal to the total sum of the maximum output voltages of the plurality of solar cell assembly series electrically connected in series. - In the solar cell panel constructed as mentioned above, the last solar cell assembly of the first solar
cell assembly series 9 a which is located at the lowermost end thereof shown in the figure is electrically connected in series with the first solar cell assembly of the second solarcell assembly series 9 b which is located at the uppermost end thereof shown in the figure by aconnection line 10. Therefore, since the solar cells in the first solarcell assembly series 9 a which are running from the uppermost end thereof shown in the figure have respective potentials u, 2 u, . . . , (n−1)*u, and n*u, and the solar cells in the second solarcell assembly series 9 b which are running from the uppermost end thereof shown in the figure have respective potentials V+u, V+2 u, V+(n−1)*u, and V+n*u, any two adjacent solar cells in the first and second solar cell assembly series can have a potential difference which does not exceed V. - Then, connections among solar cell assembly series including up to the Nth solar
cell assembly series 9 c are repeatedly carried out. Thus, the plurality of solar cell assembly series are arranged so that they have an identical gradient direction in their potentials in the solar cell string. Conventionally, any two adjacent solar cells have a maximum potential difference of 2V volts. In contrast, in accordance with this embodiment, the potential difference between any two adjacent solar cells in any two adjacent solar cell assembly series is greatly reduced to V volts which is the maximum output voltage of each solar cell assembly series or less. - As a result, electric discharges can be prevented from occurring between any solar cells in the solar cell panel. The weight of the solar cell panel can be reduced, the efficiency of mounting solar cells in the solar cell panel can be increased, and the cost of the solar cell panel can be reduced. In addition, when installing an insulating barrier into the gap between any two solar cells, an adequate margin of safety can be provided against electric discharges between solar cells as compared with prior art solar cell panels.

The solar cell string 11 a and the solar cell string 11 b are connected in parallel so that asolar cell module 12 is constructed. - The first series of the N solar
cell assembly series 9 a is arranged at the leftmost end of the solar cell module, and the first series of the N solarcell assembly series 9 b is arranged at the rightmost end of the solar cell module. The first series of the N solarcell assembly series 9 a is so arranged as to have a direction of potential difference between 0 volts at its uppermost end and V volts at its lowermost end, and the first series of the N solarcell assembly series 9 b is so arranged as to have a direction of potential difference between 0 volts at its lowermost end and V volts at its uppermost end. - In the solar cell panel constructed as mentioned above, the first series of the N solar

In contrast, in accordance with this embodiment, the potential difference between any two adjacent solar cells in any two adjacent solar cell assembly series is greatly reduced to V volts which is the maximum output voltage of each solar cell assembly series or less. - As a result, electric discharges can be prevented from occurring between any solar cells in the solar cell panel. The weight of the solar cell panel can be reduced, the efficiency of mounting solar cells in the solar cell panel can be increased, and the cost of the solar cell panel can be reduced. In addition, when installing an insulating barrier into the gap between any two solar cells, an adequate margin of safety can be provided against electric discharges between solar cells as compared with prior art solar cell panels.

FIG. 5 is a diagram showing solar cell circuitry according toembodiment 3 of the present invention. - In
FIG. 5 , nsolar cell assemblies 8 a each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 a is constructed. Each solarcell assembly series 9 a has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 a are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 a is constructed. - Similarly, n
solar cell assemblies 8 b each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 b is constructed. Each solarcell assembly series 9 b has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 b are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 b is constructed. The solar cell string 11 a and the solar cell string 11 b are connected in parallel so that asolar cell module 12 a is constructed. - In addition, n
solar cell assemblies 8 c each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 c is constructed. Each solarcell assembly series 9 c has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 c are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 c is constructed. - Similarly, n
solar cell assemblies 8 d each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 d is constructed. Each solarcell assembly series 9 d has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 d are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 d is constructed. The solar cell string 11 c and the solar cell string 11 d are connected in parallel so that asolar cell module 12 b is constructed. - In the solar cell panel constructed as mentioned above, the first series of the N solar
cell assembly series 9 a and the second series of the N solarcell assembly series 9 b are so arranged as to be adjacent to each other. Therefore, since the solar cells in the first series of the N solarcell assembly series 9 a which are running from the uppermost end thereof shown in the figure have respective output potentials u, 2 u, . . . , (n−1)*u, and n*u, and the solar cells in the second series of the N solarcell assembly series 9 b which are running from the uppermost end thereof shown in the figure have respective output potentials V+u, V+2 u, . . . , V+(n−1)*u, and V+n*u, any two adjacent solar cells in the first series of the N solarcell assembly series 9 a and the second series of the N solarcell assembly series 9 b can have a potential difference which does not exceed V. - Similarly, any other solar
cell assembly series 9 a which constitutes the solar cell string 11 a in thesolar cell module 12 a and a corresponding solarcell assembly series 9 b which constitutes the other solar cell string 11 b connected in parallel with the solar cell string 11 a are so arranged as to be adjacent to each other. Therefore, any two adjacent solar cells in any two adjacent solarcell assembly series solar cell module 12 a can have a potential difference which does not exceed V. - In addition, the first series of the N solar
cell assembly series 9 c and the second series of the N solarcell assembly series 9 d are so arranged as to be adjacent to each other. Therefore, since the solar cells in the first series of the N solarcell assembly series 9 c which are running from the uppermost end thereof shown in the figure have respective output potentials u, 2 u, . . . , (n−1)*u, and n*u, and the solar cells in the second series of the N solarcell assembly series 9 d which are running from the uppermost end thereof shown in the figure have respective output potentials V+u, V+2 u, V+(n−1)*u, and V+n*u, any two adjacent solar cells in the first series of the N solarcell assembly series 9 c and the second series of the N solarcell assembly series 9 d can have a potential difference which does not exceed V. - Similarly, any other solar
cell assembly series 9 c which constitutes the solar cell string 11 c in thesolar cell module 12 b and a corresponding solarcell assembly series 9 d which constitutes the other solar cell string 11 d connected in parallel with the solar cell string 11 c are so arranged as to be adjacent to each other. Therefore, any two adjacent solar cells in any two adjacent solarcell assembly series solar cell module 12 b can have a potential difference which does not exceed V. - The
solar cell module 12 a and thesolar cell module 12 b are so arranged that they are point symmetric to each other with respect to a center of a boundary line between thesolar cell module 12 a and thesolar cell module 12 b, Therefore, since the first series of the N solarcell assembly series 9 b and the first series of the N solarcell assembly series 9 c are so arranged they are point symmetric to each other with respect to the center of the boundary line, the solar cells in the first series of the N solarcell assembly series 9 b which are running from the uppermost end thereof shown in the figure have respective output potentials n*u, (n−1)*u, . . . , 2*u, and u, and the solar cells in the first series of the N solarcell assembly series 9 c which are running from the uppermost end thereof shown in the FIG. have respective output potentials u, 2 u, . . . , (n−1)*u, and n*u. - Therefore, the maximum potential of the solar cell assembly series within each solar cell module, which is arranged adjacent to the other solar cell module, can be reduced to the maximum output voltage V of each solar cell assembly series or less.
- Thus, even if the output voltage of each solar cell module changes in a range from 0 volts to the maximum output voltage V, according to control by a power control circuit, the potential difference between any two adjacent solar cells in any two solar cell assembly series of the solar cell panel, as well as the potential difference between the two adjacent solar cell modules, can be always reduced to the maximum output voltage V of each solar cell assembly series or less.
- As a result, electric discharges can be prevented from occurring between any solar cells in the solar cell panel. The weight of the solar cell panel can be reduced, the efficiency of mounting solar cells in the solar cell panel can be increased, and the cost of the solar cell panel can be reduced. In addition, when installing an insulating barrier into the gap between any two solar cells, an adequate margin of safety can be provided against electric discharges between solar cells as compared with prior art solar cell panels.

FIG. 6 is a diagram showing solar cell circuitry according toembodiment 4 of the present invention. - In
FIG. 6 , nsolar cell assemblies 8 a each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 a is constructed. Each solarcell assembly series 9 a has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 a are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 a is constructed. - Similarly, n
solar cell assemblies 8 b each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 b is constructed. Each solarcell assembly series 9 b has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 b are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 b is constructed. The solar cell string 11 a and the solar cell string 11 b are connected in parallel so that asolar cell module 12 a is constructed. - In addition, n
solar cell assemblies 8 c each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 c is constructed. Each solarcell assembly series 9 c has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 c are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 c is constructed. - Similarly, n
solar cell assemblies 8 d each having a maximum output voltage u are arranged substantially in a line so that each solarcell assembly series 9 d is constructed. Each solarcell assembly series 9 d has a maximum output voltage V=n*u. Furthermore, N solarcell assembly series 9 d are electrically connected in series by way ofconnection lines 10 so that a solar cell string 11 d is constructed. The solar cell string 11 c and the solar cell string 11 d are connected in parallel so that asolar cell module 12 b is constructed. - In the solar cell panel constructed as mentioned above, the first series of the N solar
cell assembly series 9 a and the second series of the N solarcell assembly series 9 b are so arranged as to be adjacent to each other. Therefore, since the solar cells in the first series of the N solarcell assembly series 9 a which are running from the uppermost end thereof shown in the figure have respective output potentials u, 2 u, . . . , (n−1)*u, and n*u, and the solar cells in the second series of the N solarcell assembly series 9 b which are running from the uppermost end thereof shown in the figure have respective output potentials V+u, V+2 u, V+(n−1)*u, and V+n*u, any two adjacent solar cells in the first series of the N solarcell assembly series 9 a and the second series of the N solarcell assembly series 9 b can have a potential difference which does not exceed V. - Similarly, any other solar
cell assembly series 9 a which constitutes the solar cell string 11 a in thesolar cell module 12 a and a corresponding solarcell assembly series 9 b which constitutes the other solar cell string 11 b connected in parallel with the solar cell string 11 a are so arranged as to be adjacent to each other. Therefore, any two adjacent solar cells in any two adjacent solarcell assembly series solar cell module 12 a can have a potential difference which does not exceed V. - In addition, the first series of the N solar
cell assembly series 9 c and the second series of the N solarcell assembly series 9 d are so arranged as to be adjacent to each other. Therefore, since the solar cells in the first series of the N solarcell assembly series 9 c which are running from the uppermost end thereof shown in the figure have respective output potentials u, 2 u, . . . , (n−1)*u, and n*u, and the solar cells in the second series of the N solarcell assembly series 9 d which are running from the uppermost end thereof shown in the figure have respective output potentials V+u, V+2 u, . . . , V+(n−1)*u, and V+n*u, any two adjacent solar cells in the first series of the N solarcell assembly series 9 c and the second series of the N solarcell assembly series 9 d can have a potential difference which does not exceed V. - Similarly, any other solar
cell assembly series 9 c which constitutes the solar cell string 11 c in thesolar cell module 12 b and a corresponding solarcell assembly series 9 d which constitutes the other solar cell string 11 d connected in parallel with the solar cell string 11 c are so arranged as to be adjacent to each other. Therefore, any two adjacent solar cells in any two adjacent solarcell assembly series solar cell module 12 b can have a potential difference which does not exceed V. - In addition, the
solar cell module 12 a and thesolar cell module 12 b are so arranged that they are line symmetric to each other with respect to a boundary line between thesolar cell module 12 a and thesolar cell module 12 b, Therefore, since the first series of the N solarcell assembly series 9 b and the first series of the N solarcell assembly series 9 c are so arranged they are line symmetric to each other with respect to the boundary line, the solar cells in the first series of the N solarcell assembly series 9 b which are running from the uppermost end thereof shown in the figure have respective output potentials n*u, (n−1)*u, . . . , 2*u, and u, and the solar cells in the first series of the N solarcell assembly series 9 c which are running from the uppermost end thereof shown in the figure have respective output potentials n*u, (n−1)*u, . . . , 2*u, and u. The solar cell assembly series within one solar cell module is therefore arranged at a potential difference of 0 volts with its neighboring solar cell assembly series within the other solar cell module. - Thus, even if the output voltage of each solar cell module changes in a range from 0 volts to the maximum output voltage V1 according to control by a power control circuit, the potential difference between any two adjacent solar cells in any two solar cell assembly series of the solar cell panel, as well as the potential difference between the two adjacent solar cell modules, can be always reduced to the maximum output voltage V of each solar cell assembly series or less.
- In addition, since the solar cell assembly series pattern of the
solar cell module 12 a has line symmetry with respect to the solar cell assembly series pattern of thesolar cell module 12 b, the magnetic field caused by one of the two solar cell modules can be canceled by the magnetic field caused by the other solar cell module. - As a result, electric discharges can be prevented from occurring between any solar cells in the solar cell panel. The weight of the solar cell panel can be reduced, the efficiency of mounting solar cells in the solar cell panel can be increased, and the cost of the solar cell panel can be reduced. In addition, when installing an insulating barrier into the gap between any two solar cells, an adequate margin of safety can be provided against electric discharges between solar cells as compared with prior art solar cell panels.
- As mentioned above, the solar cell panel according to the present invention is suitable for use in spacecrafts, such as satellites and airships.
