Description

Technology Field

[0001] The present invention relates to a high-efficiency transparent solar cell block in which the angle or position of the solar cell can be adjusted to improve power generation efficiency. Background Technology

[0003] Recently, active efforts are being made to develop various alternative energy resources as a countermeasure against the depletion of petroleum resources.

[0004] Solar, wind, geothermal, and hydroelectric power are being researched as major alternative energy sources. Among these, solar power generation is frequently applied to buildings such as apartments and office buildings due to its advantages, including relatively fewer restrictions on installation locations compared to other renewable energy sources, ease of installation, and the ability to freely adjust the scale of power generation.

[0005] Solar power generation has frequently utilized the Building Applied Photovoltaic (BAPV) method, which involves installing solar panels on building roofs or rooftops. Recently, Building Integrated Photovoltaic (BIPV), which integrates solar panels into building materials and installs them on the exterior of buildings, has been developed and is being applied to many structures.

[0006] BIPV systems offer the advantage of not requiring installation space and reducing construction costs by utilizing them as building exterior materials to generate electricity. Additionally, integrating display modules or dye-sensitized solar cells into BIPV systems can enhance the aesthetic appeal of the building.

[0007] However, these BIPV systems have various limitations, such as low energy production efficiency and difficulties in mechanical coupling between solar cells.

[0008] To overcome the aforementioned problems, BIPV systems capable of adjusting the angle of solar cells according to the sun's altitude are being developed; however, frequently changing the angle as the sun's altitude changes is cumbersome, and efficiency remains low due to reduced shading caused by adjacent solar cells. Additionally, while solar cells utilizing thin-film technology are being developed, they face difficulties in improving power generation efficiency and resolving challenges related to mechanical coupling.

[0009] Accordingly, there is a need to develop transparent solar cells that are easy to apply to BIPV systems, as they offer higher energy production efficiency, ease of mechanical coupling, and excellent transparency compared to existing BIPV systems. The problem to be solved

[0011] A high-efficiency transparent solar cell block according to one embodiment of the present invention is proposed to solve the above-mentioned problem, wherein the angle or position of the solar cell is changed to maximize the absorption of sunlight within the internal space of a polyhedron with some faces being transparent, thereby improving photoelectric conversion efficiency, and the effect of facilitating mutual coupling with other polyhedra through a fastening member can be provided. means of solving the problem

[0013] According to one embodiment, a high-efficiency transparent solar cell block may include: a polyhedron having at least some faces that are transparent; a solar cell disposed on the surface or internal space of the polyhedron; a driving means for adjusting the angle or position of the solar cell; a light intensity detection sensor disposed on the driving means; a controller for controlling the driving means; and a fastening member disposed on the surface of the polyhedron.

[0014] In addition, the polyhedron is in the shape of a cuboid and has a front face and a back face, an upper face and a lower face, and a first side face and a second side face that are parallel to each other, and the front face and the back face may become the exposed surface after joining.

[0015] In addition, the solar cell may be positioned at an angle to form a predetermined angle with respect to the lower surface of the polyhedron.

[0016] In addition, the light intensity detection sensor is positioned on the outside of the solar cell and, after detecting the incident sunlight intensity, can transmit the detected light intensity data to the controller.

[0017] In addition, the controller can use an artificial intelligence model to predict the optimal angle or position of the solar cell that can obtain maximum power production efficiency based on the position information of the solar cell and the light intensity data, and control the driving means so that the angle or position of the solar cell is adjusted based on the optimal angle or position predicted by the artificial intelligence model.

[0018] In addition, the controller can transmit a first control signal for adjusting the angle of the solar cell and a second control signal for adjusting the position of the solar cell to the driving means.

[0019] Additionally, the driving means may include: a support plate on which the solar cell is disposed on the front surface; a moving member in which a portion of the upper surface is connected to one corner of the support plate and which supports the support plate so that it can rotate around one corner; and a frame disposed at the bottom of the moving member.

[0020] In addition, the moving member may include a first permanent magnet and a second permanent magnet installed at each of both ends.

[0021] Additionally, the support plate can be rotated so that the distance from the first permanent magnet becomes closer or farther through a first electromagnet positioned on the rear side.

[0022] In addition, the frame can support the moving member so that it moves in a direction that reduces the distance from the second electromagnet or the distance from the third electromagnet through a second electromagnet and a third electromagnet disposed at each end.

[0023] In addition, the above-mentioned fastening member can combine multiple different polyhedra arranged adjacently in the horizontal and vertical directions so that the positions of the multiple different polyhedra are fixed in the horizontal and vertical directions.

[0024] Additionally, the fastening member may include: a first protrusion formed to protrude on the first side; a first insertion groove formed in a groove shape on the second side so that the first protrusion of an adjacent polyhedron is fitted and coupled; a second protrusion formed to protrude on the upper surface; and a second insertion groove formed in a groove shape on the lower surface so that the second protrusion of an adjacent polyhedron is fitted and coupled.

[0025] In addition, the polyhedron, solar cell, and driving means are formed of a flexible material and can be deformed into a preset shape.

[0026] In addition, a BIPV (Building Integrated Photovoltaics) transparent solar panel formed by the mutual combination of any one of the selected high-efficiency transparent solar cell blocks can be provided. Effects of the invention

[0028] A high-efficiency transparent solar cell block according to one embodiment of the present invention can improve photoelectric conversion efficiency by changing the angle or position of the solar cell so as to absorb sunlight to the maximum extent within the internal space of a polyhedron where some faces are transparent, and can secure the effect of easy mutual coupling with other polyhedra through a fastening member.

[0041] Hereinafter, various embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In describing the embodiments, technical details that are well known in the art to which the present invention pertains and are not directly related to the present invention will be omitted. This is to ensure that the essence of the present invention is conveyed more clearly without obscuring it by omitting unnecessary explanations. For the same reason, some components in the accompanying drawings may be exaggerated, omitted, or schematically depicted. Furthermore, the size of each component does not entirely reflect its actual size. Throughout this specification, the same reference numerals may refer to the same or corresponding components.

[0043] Conventional solar cell modules use methods such as changing the angle according to the sun's altitude or using reflectors to increase efficiency, but the efficiency improvement effect is still insufficient. In addition, there have been limitations in applying them to BIPV systems due to the complexity of robust mechanical coupling between solar cells. On the other hand, the high-efficiency transparent solar cell block of the present invention improves solar light absorption efficiency by changing the angle or position of solar cells placed in the internal space of a polyhedron based on position information and light intensity data of the solar cells, and can have the effect of facilitating robust coupling with other polyhedra through fastening members on the surface of the polyhedron.

[0044] Below, a high-efficiency transparent solar cell block with improved solar light absorption efficiency and easy mutual coupling is described.

[0046] FIG. 1 is a diagram schematically illustrating the structure of a high-efficiency transparent solar cell block according to one embodiment of the present invention.

[0047] Referring to FIG. 1, a high-efficiency transparent solar cell block (1000) may include a polyhedron (100), a solar cell (200), a driving means (300), a light intensity detection sensor (400), a controller (500), and a fastening member (600).

[0048] Specifically, the polyhedron (100) may be manufactured with at least some of its faces transparent. In one embodiment of the present invention, the polyhedron (100) is in the shape of a hexahedron and has a front face and a back face, an upper face and a lower face, and a first side face and a second side face that are parallel to each other, and the front face and the back face may become the exposed surface after joining.

[0049] However, the polyhedron (100) is not limited to this and can be formed in various shapes.

[0050] The polyhedron (100) may be manufactured with a material that is transparent in some or all of its faces. For example, the polyhedron (100) may be manufactured with transparent front and back surfaces, which are exposed surfaces, and sunlight may pass through the front and back surfaces and be irradiated into the interior of the polyhedron (100).

[0051] The polyhedron (100) may be manufactured from one or more transparent materials selected from the group comprising ethylene-tetrafluoroethylene (ETFE), polymethyl methacrylate (PMMA), and polycarbonate (PC). However, not limited thereto, the polyhedron (100) may be manufactured from a material having plasticity, durability, and excellent transparency.

[0052] Here, the polyhedron (100) is manufactured so that some faces can be opened and closed, making it easy to insert and remove other components inside.

[0053] The solar cell (200) may be placed on the surface or inside space of the polyhedron (100). For example, the solar cell (200) may be placed at an angle to form a predetermined angle with respect to the lower surface of the polyhedron (100) in the inside space of the polyhedron (100).

[0054] At this time, the angle formed by the solar cell (200) with respect to the lower surface of the polyhedron (100) may be 0 to 45 degrees. Preferably, the angle formed by the solar cell (200) with respect to the polyhedron (100) may be 10 to 25 degrees.

[0055] Meanwhile, the solar cell (200) may also be placed on the surface of the polyhedron (100). For example, the solar cell (200) may be placed on the transparent exposed surface of the hexahedron-shaped polyhedron (200) to absorb sunlight.

[0056] In one embodiment of the present invention, the solar cell (200) may be manufactured as a solar cell (200) including a thin-film light absorption layer. Here, the thin-film light absorption layer of the solar cell (200) may be a single layer or a multilayer.

[0057] Additionally, the thin-film light absorption layer of the solar cell (200) can be manufactured from a thin-film photoactive material. For example, the light absorption layer of the solar cell (200) may use at least one selected from the group consisting of silicon (Si), CIGS (Copper Indium Gallium Selenide) layer, a group III-V element composite layer, a photoactive organic layer, and a perovskite layer as the thin-film light absorption layer.

[0058] Accordingly, the solar cell (200) can be manufactured to be transparent or opaque and placed on the surface or inside space of the polyhedron (100).

[0059] The solar cell (200) may be placed in the internal space of the polyhedron (100) in a form having only a basic structure for power generation. Specifically, the solar cell (200) may include a transparent electrode, a light absorption layer, and a charge transfer layer.

[0060] However, the solar cell (200) may be placed in the internal space of the polyhedron (100) in a form with enhanced mechanical strength and durability. Specifically, the solar cell (200) may include a transparent electrode, a light absorption layer, a charge transfer layer, a transparent substrate, and a protective film.

[0061] The driving means (300) is placed in the internal space of the polyhedron (100) and can adjust the angle or position of the solar cell (200).

[0062] Specifically, the driving means (300) may include a support plate (310, see FIG. 3) on which a solar cell (200) is placed on the front, a moving member (320, see FIG. 3) which is connected to a part of the upper surface and one corner of the support plate (310) and supports the support plate (310) so that it can rotate around one corner, and a frame (330, see FIG. 3) placed on the lower part of the moving member (320).

[0063] A specific description of how the driving means (300) adjusts the angle or position of the solar cell (200) will be explained in detail below with reference to FIG. 3.

[0064] The light intensity detection sensor (400) may be placed on the driving means (300). Additionally, the light intensity detection sensor (400) may be placed on the outside of the solar cell (200). Specifically, the light intensity detection sensor (400) may be placed adjacent to the outside of the solar cell (200) which is placed on the support plate (310) of the driving means (300).

[0065] Accordingly, the light intensity detection sensor (400) can detect the amount of incident sunlight incident on the solar cell (200). Here, at least one of the light intensity detection sensors (400) may be positioned adjacent to the outside of the solar cell (200) to reduce the error in the detected amount of incident sunlight.

[0066] The light intensity detection sensor (400) can detect the amount of sunlight incident on the solar cell (200) and transmit it to the controller (500).

[0067] That is, the light intensity detection sensor (400) is positioned on the outside of the solar cell (200), and after detecting the amount of incident sunlight, the detected light intensity data can be transmitted to the controller (500, see FIG. 2).

[0068] Afterwards, the controller (500) can use an artificial intelligence model to predict the optimal angle or position of the solar cell (200) that can obtain maximum power production efficiency based on the position information and light intensity data of the solar cell (200), and can control the driving means (300) so that the angle or position of the solar cell is adjusted based on the optimal angle or position predicted by the artificial intelligence model.

[0069] Here, the optimal angle or position of the solar cell (200) that can obtain maximum power production efficiency may be an angle or position where the surface of the solar cell (200) can be exposed to sunlight to the maximum extent.

[0070] That is, the optimal angle or position may be an angle or position where the solar cell (200) can absorb sunlight to the maximum extent.

[0071] Specifically, the controller (500) inputs light quantity data transmitted by the light quantity detection sensor (400) and location information of the solar cell (200) inside the polyhedron (100) into an artificial intelligence model and can predict the angle or location at which the solar cell (200) can absorb sunlight to the maximum extent.

[0072] Additionally, the controller (500) can predict an optimal angle or position suitable for each solar cell (200) based on relative position information of each solar cell (200) when a plurality of solar cell blocks (1000) are combined with each other (see FIG. 4) or when at least one solar cell block (1000) is placed in an adjacent position to each other.

[0073] For example, the controller (500) can predict an optimal angle or position suitable for each solar cell (200) so that the solar cell (200) in the internal space of the polyhedron (100) placed at the top does not block sunlight reaching the solar cell (200) in the internal space of the polyhedron (100) placed at the bottom.

[0074] Afterwards, the controller (500) can adjust the angle or position of the solar cell (200) by transmitting a control signal to the driving means (300) based on the predicted optimal angle or position.

[0075] Meanwhile, when a plurality of light intensity detection sensors (400) are placed inside each solar cell block (1000), the controller (500) can input the light intensity data transmitted by the plurality of light intensity detection sensors (400) into an artificial intelligence model to calculate an average value.

[0076] Afterwards, the controller (500) can adjust the angle of the solar cell (200) through a method similar to the process described above.

[0077] A transparent solar cell block (1000) according to one embodiment of the present invention may include a fastening member (600) disposed on a surface.

[0078] Specifically, the fastening member (600) can combine multiple different polyhedra (100) arranged adjacently in the horizontal and vertical directions so that the multiple different polyhedra (100) can be fixed in position in the horizontal and vertical directions.

[0079] Accordingly, a solar cell block (1000) can be easily joined to an adjacent solar cell block (1000) through a fastening member (600). Here, the fastening member (600) is manufactured in a corresponding shape to enable joining to each other, so that they can be firmly joined.

[0080] For example, the fastening member (600) may include a first protrusion (610) formed to protrude on a first side of a cuboid-shaped polyhedron (100), a first insertion groove (620) formed in a groove shape on a second side so that the first protrusion (610) of an adjacent polyhedron is fitted and coupled, a second protrusion (630) formed to protrude on an upper surface, and a second insertion groove (640) formed in a groove shape on a lower surface so that the second protrusion (630) of an adjacent polyhedron is fitted and coupled.

[0081] Here, the first protrusion (610) is a rectangular column shape extending parallel to the corner of the first side, and the second protrusion (630) may be a rectangular column shape formed on a part of the upper surface.

[0082] Additionally, two first protrusions (610) may be formed on the first side, and two second protrusions (630) may be formed on the front corners of the upper surface and two on the rear corners, for a total of four.

[0083] At this time, the first groove (620) may be formed on the second side so as to be combined with all first protrusions (610) of the adjacent polyhedron (100).

[0084] The second groove (640) may be formed on the second side or bottom surface so as to be combined with all second protrusions (630) of an adjacent polyhedron (100).

[0085] However, the shape, number, and placement location of the first protrusion (610) and the second protrusion (630) are not limited to this and may vary. Additionally, the first groove (620) and the second groove (640) may also be formed in various ways to correspond to each of these.

[0087] Below, the operation sequence of the high-efficiency solar cell block (1000) of the present invention will be explained with reference to FIG. 2.

[0088] FIG. 2 is a block diagram illustrating the operation sequence of a high-efficiency solar cell block according to one embodiment of the present invention.

[0089] Referring to FIG. 2, the high-efficiency solar cell block (1000) may include a driving means (300), a light intensity detection sensor (400), and a controller (500).

[0090] First, a light intensity detection sensor (400) is placed on the outside of a solar cell (200, see FIG. 1) to detect the amount of incident sunlight, and then transmits the detected light intensity data to a controller (500).

[0091] Here, the light intensity detection sensor (400) may be positioned adjacent to the solar cell (200) on the support plate (310, see FIG. 3) of the driving means (300). Thus, the light intensity detection sensor (400) can approximately detect the amount of sunlight incident on the solar cell (200).

[0092] The light intensity detection sensor (400) can generate light intensity data based on the detected incident sunlight intensity. The light intensity detection sensor (400) can transmit the light intensity data to the controller (500).

[0093] Meanwhile, the light intensity detection sensor (400) may be at least one selected from the group including a photodiode-based sensor, a quantum sensor, and a thermopile-based sensor, but is not limited thereto.

[0094] The controller (500) inputs the location information of the solar cell (200) and the light intensity data received from the light intensity detection sensor (400) into an artificial intelligence model to predict the optimal angle or position at which the solar cell (200) can be exposed to sunlight to the maximum extent.

[0095] And the controller (500) can transmit a control signal to the driving means (300) based on the optimal angle or position predicted by the artificial intelligence model.

[0096] Specifically, the controller (500) can transmit a first control signal for adjusting the angle of the solar cell (200) and a second control signal for adjusting the position of the solar cell (200) to the driving means (300).

[0097] That is, the controller (500) can adjust the angle or position of the solar cell (200) placed on the front of the driving means (300) through the first control signal and the second control signal.

[0098] Here, the first control signal and the second control signal may be one or more signals selected from Wireless Power Transfer (WPT), Radio Frequency Signal, and Microwave Power Transmission (MPT), but are not limited thereto.

[0099] Thus, the high-efficiency transparent solar cell block (1000) of the present invention can improve efficiency by arranging the solar cell (200) at an angle or position that can absorb sunlight to the maximum extent within the space inside the polyhedron (100, see FIG. 1).

[0101] FIG. 3 is a drawing for explaining a driving means according to an embodiment of the present invention.

[0102] Referring to FIG. 3, the driving means (300) may include a support plate (310), a moving member (320), and a frame (330).

[0103] Specifically, the driving means (300) may include a support plate (310) on which a solar cell (200) is placed on the front.

[0104] Here, the driving means (300) can be arranged in the order of frame (330), moving member (320), and support plate (310) from the bottom surface of the polyhedron (100).

[0105] The support plate (310) may include a light intensity detection sensor (400) adjacent to the outer side of the solar cell (200) attached to the front. Additionally, the support plate (310) may include at least one light intensity detection sensor (400) to improve the accuracy of the detected incident sunlight intensity.

[0106] Additionally, the support plate (310) may include a first electromagnet (311) positioned on the rear side. Here, the first electromagnet (311) is positioned on the rear side of the support plate (310) so as to face the first permanent magnet (321) described later, thereby increasing mutual influence with the first permanent magnet (321).

[0107] For example, when the angle formed by the support plate (310) with respect to the upper surface of the movable member (320) is 0 degrees, the first electromagnet (311) can be positioned above the first permanent magnet (321).

[0108] The driving means (300) may include a moving member (320) that is connected to a part of the upper surface and one corner of the support plate (310) and supports the support plate (310) so that it can rotate around one corner.

[0109] Specifically, a portion of the upper surface of the movable member (320) can be hinged to one corner (H) of the lower surface of the support plate (310). Thus, the movable member (320) can support the support plate (310) so that it rotates around one corner, thereby changing the angle of the solar cell (200) relative to the upper surface of the movable member (320).

[0110] Additionally, the movable member (320) may include a first permanent magnet (321) and a second permanent magnet (322) installed at each of both ends. Accordingly, the movable member (320) can interact with the support plate (310) or frame (330) through the first permanent magnet (321) and the second permanent magnet (322).

[0111] The driving means (300) may include a frame (330) positioned at the bottom of the moving member (320).

[0112] Specifically, the frame (330) is positioned in the internal space of the polyhedron (100) to support the movable member (320) and the support plate (310). That is, the frame (330) provides a space for the movable member (320) and the support plate (310) to move, and supports the solar cell (200) so that its position can be changed.

[0113] Meanwhile, the frame (330) may include a second electromagnet (331) and a third electromagnet (332) disposed at both ends. Accordingly, the frame (330) can support the moving member (320) to move through the first permanent magnet (321) and the second permanent magnet (322) in the space between the second electromagnet (331) and the third electromagnet (332).

[0115] Hereinafter, a method for changing the angle and position of a solar cell (200) using a high-efficiency transparent solar cell block (1000) according to one embodiment of the present invention will be described sequentially.

[0116] First, a driving means (300) may be placed in the internal space of the polyhedron (100). Then, a light intensity detection sensor (400) may detect the incident light intensity of sunlight and then transmit the detected incident light intensity data to a controller (500, see FIG. 2).

[0117] The controller (500) can predict the optimal angle or position of the solar cell (200) by inputting the position information of the solar cell (200) and the light amount data received from the light amount detection sensor (400) into an artificial intelligence model.

[0118] Afterwards, the controller (500) can transmit a first control signal to the driving means (300) based on the optimal angle predicted by the artificial intelligence model.

[0119] Specifically, the first electromagnet (311) of the support plate (310) can receive a first control signal and be induced to have current flowing inside. Accordingly, the first electromagnet (311) can have magnetic polarity in the same direction as the adjacent first permanent magnet (321) due to the first control signal.

[0120] For example, when the magnetic polarity of the first permanent magnet (321) is N-pole to S-pole from the end direction of the moving member (320), the first electromagnet (311) can receive a first control signal and be induced to have the same direction of magnetic polarity as the first permanent magnet (321).

[0121] Accordingly, the support plate (310) can be rotated so that the distance from the first permanent magnet (321) becomes closer or farther through the first electromagnet (311) placed on the rear side.

[0122] Additionally, the first electromagnet (311) can change the strength of the magnetic field by changing the magnitude of the current induced according to the first control signal. Accordingly, the angle of the support plate (310) with respect to the upper surface of the movable member (320) can be adjusted by changing the magnitude of the repulsive force between the first electromagnet (311) and the adjacent first permanent magnet (321).

[0123] Here, the angle of the support plate (310) can be fixed at a position where the repulsive force between the first electromagnet (311) and the first permanent magnet (321) becomes equal to gravity.

[0124] Additionally, depending on the situation, the direction of the current induced in the first electromagnet (311) according to the first control signal may be changed so that the direction of the magnetic field is changed.

[0125] Meanwhile, the controller (500) can transmit a second control signal to the driving means (300) based on the optimal position predicted by the artificial intelligence model.

[0126] Here, the second electromagnet (331) and the third electromagnet (332) of the frame (330) can receive a second control signal and be induced to have current flowing inside. Accordingly, the second electromagnet (331) and the third electromagnet (332) can have magnetic polarity due to the second control signal.

[0127] At this time, the magnitude of the current induced in each of the second electromagnet (331) and the third electromagnet (332) can be changed according to the second control signal, thereby changing the strength of the magnetic field in each.

[0128] In addition, the direction of the current induced in each of the second electromagnet (331) and the third electromagnet (332) can be changed according to the second control signal, thereby changing the direction of the magnetic field in each.

[0129] Accordingly, the frame (330) can support the moving member (320) so that it moves in a direction that reduces the distance to the second electromagnet (331) or the distance to the third electromagnet (332) through the second electromagnet (331) and the third electromagnet (332) respectively placed at both ends.

[0130] That is, the position of the moving member (320) can be adjusted between the second electromagnet (331) and the third electromagnet (332).

[0131] For example, when the magnetic polarity of the adjacent first permanent magnet (321) is N pole, the second electromagnet (331) receives a second control signal so that the magnetic polarity of the part adjacent to the first permanent magnet (321) can be induced to N pole.

[0132] At the same time, when the magnetic polarity of the adjacent second permanent magnet (322) is S pole, the third electromagnet (332) receives a second control signal so that the magnetic polarity of the part adjacent to the permanent magnet (322) can be induced to be S pole.

[0133] And the moving member (320) can be fixed in position at the point where the repulsive force between the second electromagnet (331) and the adjacent first permanent magnet (321) and the repulsive force between the third electromagnet (332) and the adjacent second permanent magnet (322) become equal.

[0134] Meanwhile, the moving member (320) may be fixed in position at the point where the attractive force between the second electromagnet (331) and the adjacent first permanent magnet (321) and the attractive force between the third electromagnet (332) and the adjacent second permanent magnet (322) become equal.

[0135] For example, when the magnetic polarity of the adjacent first permanent magnet (321) is N pole, the second electromagnet (331) receives a second control signal so that the magnetic polarity of the part adjacent to the first permanent magnet (321) can be induced to S pole.

[0136] At the same time, when the magnetic polarity of the adjacent second permanent magnet (322) is S pole, the third electromagnet (332) receives a second control signal so that the magnetic polarity of the part adjacent to the permanent magnet (322) can be induced to N pole.

[0137] And the moving member (320) can be fixed in position at the point where the attractive force between the second electromagnet (331) and the adjacent first permanent magnet (321) and the attractive force between the third electromagnet (332) and the adjacent second permanent magnet (322) become equal.

[0138] Additionally, according to the principle described above, the moving member (320) can be connected to the second electromagnet (331) through the first permanent magnet (321). Here, an attractive force may act between the first permanent magnet (321) and the second electromagnet (331), and a repulsive force may act between the second permanent magnet (322) and the third electromagnet (332).

[0139] Additionally, according to the principle described above, the moving member (320) can be connected to the third electromagnet (332) through the second permanent magnet (322). Here, an attractive force may act between the second permanent magnet (322) and the third electromagnet (332), and a repulsive force may act between the first permanent magnet (321) and the second electromagnet (331).

[0140] However, the position, direction, and number of the first electromagnet (311), the first permanent magnet (321), the second permanent magnet (322), the second electromagnet (331), and the third electromagnet (332) are not limited to this and may vary.

[0142] FIG. 4 is a drawing for explaining a Building Integrated Photovoltaics (BIPV) transparent solar cell panel according to one embodiment of the present invention.

[0143] Referring to FIG. 4, a polyhedron (100) of a high-efficiency transparent solar cell block (1000) according to one embodiment of the present invention can be combined with an adjacent polyhedron (100) through a fastening member (600).

[0144] Therefore, the polyhedron (100) can be combined with multiple different polyhedrons (100) to form a wall shape, making it easy to apply to a Building Integrated Photovoltaics (BIPV) system.

[0145] For example, a first protrusion (610) formed to protrude on a first side of a polyhedron (100) according to one embodiment of the present invention can be fitted into and coupled to a first insertion groove (620) of another polyhedron (100) adjacent to the side direction.

[0146] Additionally, a second protrusion (630) formed to protrude on the upper surface of the polyhedron (100) can be fitted into and coupled with a second insertion groove (640) adjacent to the upper direction.

[0147] Accordingly, the BIPV transparent solar cell panel (10) can be formed by combining fastening members (600) on a polyhedron (100).

[0148] Meanwhile, the manufactured BIPV transparent solar panel (10) can be reassembled after separating the combined fastening member (600). Therefore, the BIPV transparent solar panel (10) allows for easy selective replacement and repair of the solar block (1000) and can be reused during reconstruction.

[0149] Meanwhile, the controller (500, see FIG. 2) inputs the position information of the solar cell (200) and the light amount data transmitted by the light amount detection sensor (400) into an artificial intelligence model to predict the optimal angle or position at which the solar cell (200) can absorb sunlight to the maximum extent.

[0150] And the controller (500) can transmit a control signal to the driving means (300) so that the angle or position of the solar cell (200) is adjusted based on the optimal angle or position predicted by the artificial intelligence model.

[0151] Here, the control signal may include at least one of a first control signal for controlling the angle of the solar cell (200) and a second control signal for controlling the position of the solar cell (200).

[0152] Meanwhile, the solar cells (200) in the internal space of the multiple polyhedra (100) may each have different optimal angles or positions predicted by an artificial intelligence model. Accordingly, the solar cells (200) in the internal space of each polyhedron (100) may have different angles and positions relative to the lower surface of each polyhedron (100).

[0153] For example, the polyhedra (100) positioned on the right side in FIG. 4 can transmit light quantity data detected through the light quantity detection sensor (400) to the controller (500).

[0154] Subsequently, the controller (500) inputs light intensity data into a pre-trained artificial intelligence model to analyze that the angle formed by sunlight incident through the front surface of the polyhedron (100) with the lower surface of the polyhedron (100) is large. Then, the controller (500) can predict that the optimal angle of the solar cell (200) is relatively small.

[0155] Accordingly, the controller (500) can transmit a first control signal to the driving means (300) of the polyhedra (100) positioned on the right side to adjust the angle between the solar cell (200) and the lower surface of the polyhedra (100) so that it becomes smaller.

[0156] Meanwhile, the polyhedra (100) positioned on the left side in Fig. 4 can also transmit light quantity data detected through the light quantity detection sensor (400) to the controller (500).

[0157] Subsequently, the controller (500) can analyze that the angle formed by sunlight incident through the front surface of the polyhedron (100) with the lower surface of the polyhedron (100) is small by inputting light quantity data into a pre-trained artificial intelligence model. Then, the controller (500) can predict that the optimal angle of the solar cell (200) is relatively large.

[0158] Accordingly, the controller (500) can transmit a first control signal to the driving means (300) of the polyhedra (100) positioned on the left side to adjust the angle between the solar cell (200) and the lower surface of the polyhedra (100) to increase.

[0159] Meanwhile, the controller (500) can predict the optimal position of the solar cell (200) in the internal space of the polyhedron (100) placed on the top, based on the position information of the solar cell pre-entered into the artificial intelligence model, so that it is a position relatively close to the rear of the polyhedron (100).

[0160] And, the controller (500) can transmit a second control signal to the driving means (300) to adjust the position so that the solar cell (200) is brought closer to the rear surface of the polyhedron (100) positioned on the upper side.

[0161] Additionally, the controller can predict the optimal position of the solar cell (200) in the internal space of the polyhedron (100) placed at the bottom, based on the position information of the solar cell pre-entered into the artificial intelligence model, so that it is a position relatively close to the front of the polyhedron (100).

[0162] And, the controller (500) can transmit a second control signal to the driving means (300) to adjust the position so that the solar cell (200) is brought closer to the front of the polyhedron (100) placed at the bottom.

[0163] Therefore, the solar cell (200) in the internal space of the polyhedron (100) placed at the top may not block sunlight incident on the solar cell (200) in the internal space of the polyhedron (100) placed at the bottom.

[0164] Accordingly, the controller (500) can individually control the angle and position of each solar cell (200) included in the BIPV solar cell panel (10) so that they can be exposed to the maximum amount of incident sunlight, as in the example described above.

[0166] FIG. 5 is a drawing showing a display arranged on a high-efficiency transparent solar cell block according to one embodiment of the present invention.

[0167] Referring to FIG. 5, the display (700) can be placed in the interior space of the polyhedron (100). Specifically, the display (700) can be placed in a position that does not block sunlight incident on the solar cell (200).

[0168] Here, the display (700) may be an LED or an LCD, but is not limited thereto.

[0169] The display (700) is placed in the interior space of the polyhedron (100) and can emit light using power generated by the solar cell (200). Thus, the solar cell block (1000) can provide aesthetic appeal to the installed building and can display informational text or advertising text.

[0170] Meanwhile, the high-efficiency transparent solar cell block (1000) of the present invention may further include a multifunctional layer (not shown) containing a transparent liquid medium in an internal space.

[0171] At this time, the multifunctional layer is placed between the solar cell (200) and the support plate (310, see FIG. 3) to prevent overheating of the solar cell.

[0173] FIG. 6 is a diagram schematically illustrating the structure of a high-efficiency transparent solar cell block according to another embodiment of the present invention.

[0174] Referring to FIG. 6, the polyhedron (100), solar cell (200), and driving means (300) of a high-efficiency transparent solar cell block (2000) according to another embodiment are formed of a flexible material and can be deformed into a preset shape.

[0175] Therefore, the transparent solar cell block (2000) of the present invention can be applied to various buildings without being restricted by space and shape.

[0176] At this time, the high-efficiency transparent solar cell block (2000) according to another embodiment may include the components and features of the above-described embodiment. Accordingly, the high-efficiency transparent solar cell block (2000) according to another embodiment may adjust the angle or position of the solar cell (200) in the same way as the operation method of the high-efficiency transparent solar cell block (1000) according to the above-described embodiment.

[0177] Likewise, high-efficiency transparent solar cell blocks (2000) according to another embodiment can be joined together through a fastening member (600) to form a BIPV transparent solar cell panel (10, see FIG. 4).

[0179] The method according to the embodiment may be implemented in the form of program instructions that can be executed through various computer means and recorded on a computer-readable medium. The computer-readable medium may include program instructions, data files, data structures, etc., either alone or in combination. The program instructions recorded on the medium may be those specifically designed and configured for the embodiment, or they may be those known and available to those skilled in the art of computer software. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes; optical recording media such as CD-ROMs and DVDs; magneto-optical media such as floptical disks; and hardware devices specifically configured to store and execute program instructions, such as ROM, RAM, and flash memory. Examples of program instructions include machine code, such as that generated by a compiler, as well as high-level language code that can be executed by a computer using an interpreter, etc. The hardware devices described above may be configured to operate as one or more software modules to perform the operation of the embodiment, and vice versa.

[0180] Although the embodiments have been described above with reference to limited examples and drawings, those skilled in the art can make various modifications and variations from the description above. For example, suitable results can be achieved even if the described techniques are performed in a different order than described, and / or the components of the described system, structure, device, circuit, etc. are combined or assembled in a form different from described, or replaced or substituted by other components or equivalents.
