Description

Technical Field

[0001] The present invention relates to a three-dimensional foldable solar module.

[0002] In particular, the present invention relates to a three-dimensional foldable solar module that can generate solar power at a desired position without spatial constraints.

Background Art

[0003] Solar power generation produces energy using sunlight and has attracted attention as a new renewable energy as the attention to environmental issues has increased. For this reason, each country is trying to change the current energy production system to an environmentally friendly energy.

[0004] However, the solar power generation system has problems that have not been solved. The first is that it requires a large area, and the second is that it must be exposed to the outside.

[0005] The fact is that producing energy using sunlight is not more efficient than existing energy production methods. Therefore, a large number of panels are required to produce available energy, and for this reason, the panels must be positioned side by side over a large area. Therefore, solar power generation systems are installed in areas that are not urban areas with a high population density.

[0006] In addition, since solar power generation must be exposed to light, the panels must be exposed to the outside facing the sky. Therefore, there are significant restrictions on the installation of solar power generation.

[0007] Due to these two major problems, the solar power generation system has very low usability. Therefore, the current situation is that the solar power generation system has not emerged from the stage when it was first invented.

Summary of the Invention

Problems to be Solved by the Invention

[0008] The present invention aims to solve the above-mentioned problems and provide a highly practical three-dimensional foldable solar module. As an example, the present invention aims to provide a three-dimensional foldable solar module that enables solar power generation anywhere without spatial constraints. [Means for solving the problem]

[0009] A three-dimensional foldable solar module according to one embodiment may include a frame portion that forms an installation space, and a solar power generation portion that is arranged in a manner that encloses the installation space and generates energy using sunlight supplied through the installation space.

[0011] The support units may be arranged in pairs or more along the vertical direction, forming an installation space between them, and the solar power generation unit may be placed in the installation space and connected to the support units.

[0012] The support sections are arranged in a manner that separates from each other, and the photovoltaic power generation section is positioned to contact at least two of the four support sections, thereby closing off the installation space.

[0013] A folding portion is formed on one side of the support portion, allowing the support portion to be folded.

[0017] The movable connecting portion includes a first fixing member surrounding the support portion and a second fixing member surrounding the support portion at a position symmetrical to the first fixing member, and the first and second fixing members are characterized in that they can move closer together or further apart on one side, and can be fixed to or detached from the support portion and slide.

[0018] The interior of the support portion can be characterized by the formation of a space.

[0019] The frame can be characterized by having a reflective surface that reflects sunlight.

[0037] While the present invention can have various embodiments through diverse transformations, specific embodiments will be illustrated and described in detail in the detailed description. However, it should be understood that this does not limit the present invention to specific embodiments, but rather includes all transformations, equivalents, or substitutions that fall within the spirit and technical scope of the present invention.

[0038] The terms used in this invention are used solely to describe specific embodiments and are not intended to limit the invention. Singular expressions include plural expressions unless the context clearly indicates otherwise. In this invention, terms such as “includes” or “having” are intended to specify the existence of features, figures, stages, operations, components, parts, or combinations thereof as described in the specification, and should be understood not to preemptively exclude the possibility of the existence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof.

[0039] Preferred embodiments of the present invention will be described in detail below with reference to the attached drawings. Note that, in the attached drawings, identical components are represented by the same reference numerals whenever possible. Furthermore, detailed descriptions of known functions and configurations that may obscure the gist of the present invention may be omitted. For similar reasons, some components in the attached drawings may be exaggerated, omitted, or shown schematically.

[0040] A three-dimensional foldable solar module according to one embodiment of the present invention can be installed without being restricted by space. Such a system is made possible by the solar power generation unit of the present invention. Therefore, we will first examine the solar power generation unit according to one embodiment of the present invention.

[0041] Figure 1 shows the photovoltaic power generation section of a three-dimensional foldable solar module according to one embodiment of the present invention.

[0042] In this invention, the photovoltaic power generation unit 200 is formed in a shape in which particles 220 are arranged on a plate 210, as shown in Figure 1. Here, the particles 220 may be spherical particles 220 that are not visible to the naked eye, as shown in Figure 1. (Needless to say, the cross-section is circular.) Therefore, sunlight irradiated toward the photovoltaic power generation unit 200 can pass through the plate 210. Thus, in this invention, photovoltaic power generation can be performed even if the photovoltaic power generation unit 200 is arranged in a stacked shape.

[0043] In one embodiment, the photovoltaic power generation unit 200 of the present invention may be composed of a plate 210 and particles 220.

[0044] The plate 210 can be manufactured from a flexible material and may be formed into a specific shape. The plate 210 may be transparent or opaque. However, it is preferable that the plate 210 is made of a material or material that allows sunlight to pass through.

[0045] A circuit diagram can be printed on plate 210. The circuit diagram is printed on one side of plate 210 and can be connected in series or parallel. (Figure 1 shows a series circuit diagram printed on plate 210.)

[0046] The particle 220 may include a first electrode layer 221, a second electrode layer 222, a passivation layer 223, a prevention layer 224, a first connecting portion 225, and a second connecting portion 226.

[0047] The particle 220 is formed in a spherical shape with its lower end exposed. That is, the particle 220 may be formed in a spherical shape by connecting other components. The second electrode layer 222 may be positioned inside the first electrode layer 221. The first electrode layer 221 and the second electrode layer 222 may be formed with their lower sides cut horizontally. The second electrode layer 222 may be positioned inside the first electrode layer 221. The first electrode layer 221 and the second electrode layer 222 may be made of different types of silicon.

[0048] For example, the first electrode layer 221 may be N-type silicon, and the second electrode layer 222 may be P-type silicon. Therefore, when sunlight reaches the particles 220, energy can be generated by the movement of electrons and holes.

[0049] Here, if the first electrode layer 221 is N-type silicon and the second electrode layer 222 is P-type silicon, electrons and holes will accumulate at the first connecting portion 225 connected to the underside of the first electrode layer 221 and at the second connecting portion 226 located on the underside of the second electrode layer 222, respectively, thereby allowing electricity to flow through the circuit diagram of the plate 210.

[0050] Here, a passivation layer 223 may be placed outside the first electrode layer 221 to facilitate the smooth transmission of electrons and holes. A protective layer 224 may then be placed surrounding the passivation layer 223 to prevent reflection of sunlight.

[0051] Thus, the present invention enables particles 220, which are invisible to the naked eye, to produce energy. Although the energy (electrical energy) generated by each of these particles 220 is very weak, when the energies generated by them are combined, a much larger amount of energy can be produced compared to the cells in conventional solar power generation systems.

[0052] In addition, since the present invention has a circuit diagram printed on the plate 210 and particles 220 arranged above the circuit diagram, the circuit diagram can be formed in various forms and the spacing between particles 220 can also be adjusted.

[0053] Furthermore, a first connecting portion 225 and a second connecting portion 226 may be arranged on the particle 220. The first connecting portion 225 may be connected to the first electrode layer 221, and the second connecting portion 226 may be connected to the second electrode layer 222. Here, the first connecting portion 225 may be a positive electrode or a negative electrode depending on the type of the first electrode layer 221 and the second electrode layer 222, and the second connecting portion 226 may be the opposite electrode.

[0054] Thus, the solar power generation unit 200 of the present invention has the advantage of being highly versatile due to the small size of the particles 220, which create spaces between the particles 220, giving it transparency, and the flexible plate 210.

[0055] Figure 2 shows a three-dimensional foldable solar module according to a first embodiment of the present invention.

[0056] According to the first embodiment, the three-dimensional foldable solar module of the present invention may include a frame portion 100 and a solar power generation portion 200.

[0057] The frame portion 100 can mean the framework on which the solar power generation unit 200 is arranged. The frame portion 100 may include support portions 110. The support portions 110 may consist of at least two. The support portions 110 can be arranged spaced apart from each other. Therefore, an installation space 120 may be formed between the support portions 110. The installation space 120 means the space formed by the support portions 110. In the first embodiment, since there are two support portions 110, the space between the support portions 110 can become the installation space 120.

[0058] The photovoltaic power generation unit 200 is arranged in a manner that encloses the installation space 120. For example, the photovoltaic power generation unit 200 can be arranged along the longitudinal direction of the support unit 110, as shown in Figure 2. Here, the photovoltaic power generation unit 200 is formed with the structure described in Figure 1. Therefore, when the photovoltaic power generation unit 200 is arranged along the longitudinal direction, all of the photovoltaic power generation units 200 can generate energy.

[0059] In other words, when sunlight is shone from above to below, the first solar power generation unit 200 to receive sunlight generates energy using the sunlight. At this time, sunlight is transmitted through the transparency of the plate 210 and the spaces between the particles 220, allowing sunlight to be shone on the next solar power generation unit 200. Therefore, although not shown in Figure 2, the present invention allows for the arrangement of the solar power generation units 200 in a stacked structure, enabling the generation of energy with higher efficiency compared to a smaller space.

[0060] Figure 3 shows a three-dimensional foldable solar module according to a second embodiment of the present invention.

[0061] According to the second embodiment, the three-dimensional foldable solar module may include a frame section 100 and a solar power generation section 200.

[0062] The frame portion 100 may include three support portions 110. Here, the three support portions 110 may be formed to be located near the corners of a triangle. Therefore, any part of the installation space 120 may be triangular in shape. That is, the support portions 110 may be arranged to form the lines of a figure of a specific shape. Therefore, the support portions 110 may form the surface of a figure of a specific shape, which may constitute the installation space 120.

[0063] Furthermore, the installation space 120 may include a first installation space 121 and a second installation space 122.

[0064] The first installation space 121 can mean the space formed between the support parts 110. Therefore, it may be formed in a triangular shape.

[0065] The second installation space 122 can refer to the lateral space between the two support parts 110. Therefore, the second installation space 122 may be a rectangular space with the top and bottom sides open.

[0066] The plate 210 of the photovoltaic power generation unit 200 may be formed to correspond to the first installation space 121 and the second installation space 122. Therefore, the photovoltaic power generation unit 200 can be stably supported. On the other hand, since the photovoltaic power generation unit 200 is similar to the one described in Figure 1, it can transmit sunlight. Therefore, the present invention can generate energy by efficiently utilizing space. In other words, unlike existing systems, photovoltaic power generation can be performed even if the photovoltaic power generation unit 200 is arranged in a vertical direction.

[0067] On the other hand, the solar power generation unit 200 can be connected via the support unit 110 and the movable connecting unit 130.

[0068] The movable connecting portion 130 is positioned between the support portion 110 and the solar power generation portion 200, allowing the solar power generation portion 200 to be firmly connected to the support portion 110, or loosely connected so that the solar power generation portion 200 can slide along the support portion 110. The movable connecting portion 130 may include a first fixing member 131 and a second fixing member 132.

[0069] The first fixing member 131 and the second fixing member 132 may each be formed in a semicircular shape. Therefore, the first fixing member 131 and the second fixing member 132 may each be formed in a manner that surrounds the support portion 110. Parts of the first fixing member 131 and the second fixing member 132 can overlap each other. Furthermore, parts of the first fixing member 131 and the second fixing member 132 can be hinged together.

[0070] For example, the first fixing member 131 has a protruding portion, and the second fixing member 132 has a groove in which the protruding portion of the first fixing member 131 is positioned. As a result, the first fixing member 131 has a portion that overlaps with the second fixing member 132. Depending on the length (depth) of this overlapping portion, the movable connecting portion 130 may be firmly connected to the support portion 110 or loosely connected.

[0071] In other words, when the overlapping areas of the first fixing member 131 and the second fixing member 132 are in large contact and fixed, the first fixing member 131 and the second fixing member 132 strongly press against the support portion 110, so the solar power generation unit 200 does not slide and is fixed to the support portion 110. Otherwise, the first fixing member 131 and the second fixing member can slide against the support portion 110, so the solar power generation unit 200 can slide.

[0072] Furthermore, the method by which the protruding portions and grooves of the first fixing member 131 and the second fixing member 132 are fixed in position is not a problem. For example, the protruding portion of the first fixing member 131 may have a recess formed on the outside, and the groove of the second fixing member 132 may have a convex portion, resulting in a concave-convex structure. Alternatively, the protruding portion of the first fixing member 131 may be a buckle, and the groove of the second fixing member 132 may be a part that accommodates the buckle. In other words, as long as the first fixing member 131 and the second fixing member 132 are fixed to the support portion 110 to the extent that their protruding portions and grooves overlap, their structure will not be a major problem.

[0073] On the other hand, the solar power generation unit 200 can be fixed to the support unit 110 via a fixing part (indicated number). The fixing part connects and fixes the solar power generation unit 200, which is located in the second installation space 121 that does not require sliding movement, that is, the solar power generation unit 200, which is located on the side with reference to Figure 3, to the support unit 110.

[0074] Figure 4 shows a three-dimensional foldable solar module according to a third embodiment of the present invention.

[0075] Figure 5 is a diagram showing the folding process of a three-dimensional foldable solar module according to a third embodiment of the present invention.

[0076] Hereafter, the solar power generation unit 200 will be shown separated by diagonal and dotted lines. This is to allow for easy identification of the solar power generation unit 200, but it should be noted that the solar power generation unit 200 is the same as the one described in Figure 1.

[0077] According to the third embodiment, the three-dimensional foldable solar module includes a frame section (including 110 and 120), a solar power generation section 200, and a reflector section 300.

[0078] The frame portion 100 may include four support portions 110. The support portions 110 may be positioned at the corners of a square.

[0079] The support portion 110 may form a frame, and an installation space 120 may be formed between the support portions 110.

[0080] Here, the installation space 120 can mean the space between the four support parts 110, or it can mean the space between the two support parts 110. Therefore, the installation space 120 can include a first installation space 121 and a second installation space 122.

[0081] Furthermore, a folding portion 140 may be formed on the support portion 110. The role of the folding portion 140 is similar to that described in Figure 3. Therefore, the support portion 110 can be folded with respect to the folding portion 140. However, it is preferable that the folding portion 140 is formed in a symmetrical position.

[0082] That is, as shown in Figure 4, the folding section 140 may be connected in a manner that connects two support sections 110, or the folding section 140 may be connected in a manner that connects the remaining two support sections 110 that are not connected to the folding section 140. Therefore, the present invention can be folded in a symmetrical manner.

[0083] On the other hand, as shown in Figure 5(b), the portion where the folding portion 140 is formed is folded, and the portion that is not folded is fixed. Therefore, when the folding portion 140 is operated and folded, it can move so that the distance between the folding portions 140 becomes smaller. For this reason, it is preferable that the folding portion 140 is formed in a symmetrical shape.

[0084] In other words, one of the two folding sections 140 is formed to have a semicircular cross-section, and the other is formed to have a semicircular cross-section of a different shape. Therefore, when the folding section 140 operates and the support section 110 is fully folded, the respective folding sections 140 come into contact and form a circular cross-section.

[0085] The solar power generation unit 200 is positioned in the installation space 120 (first installation space 121, second installation space 122). Here, it is preferable that the solar power generation unit 200 is positioned in the first installation space 121, which is the installation space 120 formed between the four support parts 110, and in the second installation space 122, which is formed between any two of the support parts 110.

[0086] Therefore, the photovoltaic power generation unit 200 is positioned along the longitudinal direction of the support unit 110 so that it can receive sunlight from the vertical direction, or it can receive sunlight from the side.

[0087] Here, the photovoltaic power generation unit 200, which is positioned by closing the first installation space 121, can be connected to the support unit 110 via the movable connecting unit 130. The movable connecting unit 130 may include a first fixing member 131 and a second fixing member 132, as described in Figure 3. Therefore, the photovoltaic power generation unit 200 can be fixed to the support unit 110 or be slidable.

[0088] On the other hand, the solar power generation unit 200, which is located in the second installation space 122, can be fixed to the support unit 110 via a fixing part (without an instruction number). Unlike the movable connecting part 130, the fixing part allows the solar power generation unit 200 to be stably fixed to the support unit 110.

[0089] On the other hand, the guide section 150 and the movable connecting section 130 can be connected.

[0090] The guide section 150 may be fixed to the support section 110 on one side and connected to the movable connecting section 130 on the other side. The guide section 150 may be folded using the intermediate section as a reference, similar to the folding section 140. Therefore, the movable connecting section 130 can move with respect to the support section 110 only up to a length approximately that of the guide section 150.

[0091] Furthermore, the guide section 150 can assist in the movement of the movable connecting section 130. Therefore, the solar power generation section 200 can only move to a position set with respect to the support section 110, and at the same time, when the movable connecting section 130 loosely fixes the support section 110, the support section 110 can move in a straight line.

[0092] On the other hand, a reflector 300 may be placed on the lower side of the frame 100 (the lower side of the support 110). The reflector 300 plays the role of reflecting sunlight when it is irradiated onto it. Therefore, the reflector 300 can increase the efficiency of solar power generation. In other words, the reflector 300 can improve the efficiency of solar power generation by reflecting the sunlight that has passed through the solar power generation unit 200 and sending it back to the solar power generation unit 200.

[0093] On the other hand, an incident section 400 may be positioned above the frame section 100 (above the support section 110). The incident section 400 may be a plate into which sunlight enters. Here, the incident section 400 may be the photovoltaic power generation section 200 itself, or it may be a flat, rigid plate 210 through which sunlight can pass.

[0094] As can be seen in Figure 5, these three-dimensional foldable solar modules can be folded.

[0095] First, as can be seen in Figure 5(a), the portion where the first fixing member 131 and the second fixing member 132 of the movable connecting section 130 overlap is shortened to ensure the mobility of the movable connecting section 130.

[0096] Subsequently, as can be seen in Figure 5(b), the movable connecting parts 130 are moved to position the solar power generation unit 200 adjacent to the reflecting unit 300 and the incident unit 400. At this time, the guide part 150 may be folded.

[0097] Subsequently, as can be seen in Figure 5(c), the folding section 140 can be folded as a reference. Thus, the present invention can be changed from a large-volume hexahedron to a small-volume hexahedron. At this time, both sides of the folding section 140 can be in contact.

[0098] To deform the folded three-dimensional foldable solar module of the present invention back into its original shape, it is possible to perform the operations shown in Figure 5(a), (b), and (c) in reverse order.

[0099] Figure 6 shows a three-dimensional foldable solar module according to a fourth embodiment of the present invention.

[0100] According to the fourth embodiment, a battery 500 may be placed in the three-dimensional foldable solar module. That is, as shown in Figure 6, a support plate 210 can be fixed to the lower side of the reflector 300, spaced apart from the support 110. The battery 500 may then be placed between the reflector 300 and the support plate 210. Therefore, the energy generated by the solar power generation unit 200 can be transmitted to and charged by the battery 500.

[0101] On the other hand, although not shown in the figures, the three-dimensional foldable solar modules according to the above embodiments, including the fourth embodiment, can be connected to various devices and enable the operation of those devices.

[0102] For example, the aforementioned three-dimensional foldable solar module may be connected to lighting (various types of lighting, including LED lighting). Therefore, if the three-dimensional foldable solar module generates solar power, the lighting can operate.

[0103] For example, the aforementioned three-dimensional foldable solar module may be connected to an inverter. Therefore, when the three-dimensional foldable solar module generates solar power, the inverter can convert the DC current into AC current. The current converted by the inverter may then be further connected to various other devices.

[0104] For example, the aforementioned three-dimensional foldable solar module can be connected to an air conditioner. Therefore, when the three-dimensional foldable solar module generates solar power, the air conditioner can operate and supply cool air.

[0105] In addition, multiple three-dimensional foldable solar modules are provided, each capable of being connected to different devices. These different devices can then operate through a single interface. For example, the present invention allows for the operation of various devices such as lighting, inverters, and air conditioners using a terminal with a single interface.

[0106] In addition, the equipment may be placed in the space formed by the frame portion 100 and the photovoltaic power generation portion 200. For example, the frame portion 100 may form a rectangular parallelepiped, and the photovoltaic power generation portion 200 may be placed on the face of the rectangular parallelepiped. The equipment can be located inside the rectangular parallelepiped. That is, the support portions 110 may be arranged in a manner that closes off each other along the vertical axis, and in a manner that closes off each other along the horizontal axis. The photovoltaic power generation portion 200 may be arranged in a manner that closes off each other's surfaces, and the equipment may be placed in the space within it.

[0107] Figure 7 shows a cross-section of a support portion according to an embodiment of the present invention.

[0108] The support portion 110 of the present invention may have a space 111 formed inside. This space 111 may be a line space 111 in which a line carrying electrical energy is located. The line space 111 can be formed to communicate with each other when the support portions 110 come into contact with each other.

[0109] Alternatively, it may be formed to communicate with the movable connecting portion (130, see Figure 4) described above. Therefore, a wire that allows the energy (electrical energy) generated in the photovoltaic power generation unit 200 to be moved may be provided. Thus, the present invention can be arranged in various positions so that the energy generated using sunlight can be transmitted to the battery 500. The support portion 110 described in Figure 6 may be the support portion 110 of the three-dimensional foldable photovoltaic module according to the first to fourth embodiments described above.

[0110] Figure 8 shows a cross-section of a support portion according to another embodiment of the present invention.

[0111] As mentioned above, the support portion 110 in other embodiments may have a line space 111 formed inside, but the internal line space 111 is divided into a first line space 111a and a second line space 111b.

[0112] The interior of the support section 110 is divided into a first line space 111a and a second line space 111b by a partition wall 112. Therefore, the positive and negative pole lines can be arranged separately without touching each other. The partition wall 112 may have a communication hole 113 formed therein. Thus, the first line space 111a and the second line space 111b can communicate with each other through the communication hole 113. Therefore, the support section 110 according to other embodiments may be easier to organize the wires.

[0113] Figure 9 shows a three-dimensional foldable solar module according to a fifth embodiment of the present invention.

[0114] The third-dimensional foldable solar module according to the fifth embodiment is an improvement over the third-dimensional foldable solar module according to the first embodiment, and includes a frame section 100 and a solar power generation section 200. The frame section 100 is similar to that of the third-dimensional foldable solar module according to the first embodiment, and includes a support section 110 and an installation space 120.

[0115] A folding section 140 may be positioned in the center of the solar power generation section 200. The folding section 140 can be used to fold the solar power generation section 200. Therefore, if necessary, the solar power generation section 200 may be positioned folded with respect to the folding section 140.

[0116] On the other hand, although Figure 9 shows that one folding section 140 is arranged on the photovoltaic power generation section 200, the design is not limited to this, and multiple folding sections 140 may be arranged. In other words, two, three, four, or other types of folding sections 140 can be arranged, thereby allowing the photovoltaic power generation section 200 to be folded into various shapes. For example, the photovoltaic power generation section 200 may be arranged with multiple folding sections 140 to have cross-sections such as "V" or "W".

[0117] Therefore, in this invention, since the solar power generation unit 200 is folded and arranged with respect to the folding unit 140, it is possible to generate more energy than the surrounding space.

[0118] Figure 10 shows a three-dimensional foldable solar module according to the sixth embodiment of the present invention, Figure 11 shows a three-dimensional foldable solar module according to the seventh embodiment of the present invention, and Figure 12 shows one embodiment in which the three-dimensional foldable solar modules of Figures 10 and 11 are arranged.

[0119] The three-dimensional foldable solar modules according to the sixth and seventh embodiments shown in Figures 10 and 11 are modified embodiments of the third embodiment, and as shown in Figure 9, a folding section may be arranged in the solar power generation section 200.

[0120] The sixth and seventh embodiments may include a photovoltaic power generation unit 200, an inlet unit 400, and a folding unit 140. That is, the folding unit 140 may be placed in the photovoltaic power generation unit 200, and the folding unit 140 may also be placed in the inlet unit 400, and then the folding unit 140 may be placed between the photovoltaic power generation unit 200 and the inlet unit 400.

[0121] These arrangements may form a three-dimensional foldable solar module, as shown in Figures 10 and 11. That is, as shown in Figure 10, the solar power generation section 200 may be arranged spaced apart along the vertical direction relative to the drawing, with the incident section 400 positioned on the side. Alternatively, this may be rotated clockwise so that the incident section 400 is positioned on the upper side.

[0122] Furthermore, these three-dimensional foldable solar modules can be arranged in a superimposed configuration, as shown in Figure 12. In other words, one three-dimensional foldable solar module can be placed on top of another.

[0123] Alternatively, although not shown in the diagram, the three-dimensional foldable solar modules may be arranged in close contact with each other along the lateral direction. Alternatively, although not shown in the diagram, the three-dimensional foldable solar modules may be arranged in overlapping or close contact arrangements, resulting in a variety of shapes such as a cube. In this way, the present invention maximizes energy generation efficiency by arranging the three-dimensional foldable solar modules in a limited space due to the features of the solar power generation unit 200. Furthermore, unlike conventional designs, it is not limited by location.

[0124] On the other hand, although not shown in the figures, the three-dimensional foldable solar modules according to the 5th, 6th, and 7th embodiments may be connected to and arranged with various devices, as described earlier.

[0125] Furthermore, the three-dimensional foldable solar modules according to the 5th, 6th, and 7th embodiments can operate using the same interface. For example, the three-dimensional foldable solar modules according to the 5th, 6th, and 7th embodiments can be connected to each other using a terminal having a single interface.

[0126] Although one embodiment of the present invention has been described above, any person with ordinary skill in the art can modify and change the present invention in various ways, such as by adding, changing, deleting, or adding components, without departing from the spirit of the invention as described in the claims, and this is also included within the scope of the rights of the present invention.
