Description

[Technical Field]

[0001] The present invention relates to a photovoltaic power generation system.

[0002] In particular, the present invention relates to a solar power generation system that maximizes energy production efficiency by allowing a solar power generation unit to move multiple times when sunlight moves in one direction in a specific space. [Background technology]

[0003] Solar power generation is a method of generating energy using sunlight, and as environmental issues become more prominent, it is gaining attention as a new renewable energy source. As a result, many countries are trying to change their current energy production systems to more environmentally friendly energy sources.

[0004] Reflecting this situation, solar power generation in apartment buildings has recently become popular, and solar systems that can be installed in various locations such as roofs, exterior walls, eaves, and verandas have been developed.

[0005] However, the solar power generation system has some unresolved problems. First, it requires a large area, and second, it must be exposed to the outside.

[0006] It is true that generating energy using sunlight is less efficient than existing energy production methods. Therefore, a large number of cells are required to generate usable energy, and the cells must be arranged in parallel over a large area. Therefore, solar power generation systems are installed in areas that are not densely populated, not cities.

[0007] Furthermore, solar power generation requires exposure to light, so the cells must be exposed to the outside, facing the sky. This places significant constraints on the installation of solar power generation. To solve this problem, a method has been devised in which light is reflected inside a building using a reflector or other device. However, since the area inside a building is limited, only a small amount of energy can be produced due to this area limit. This makes it difficult to actually put solar power generation systems into use. Summary of the Invention [Problem to be solved by the invention]

[0008] An object of the present invention according to one embodiment is to provide a solar power generation system that solves the above-mentioned problems.

[0009] SUMMARY OF THE INVENTION An object of the present invention according to one embodiment is to provide a highly usable solar power generation system that generates a large amount of energy even in a small area.

[0010] SUMMARY OF THE INVENTION An object of the present invention according to one embodiment is to provide a highly usable solar power generation system that can generate a large amount of energy even when installed indoors. [Means for solving the problem]

[0011] A solar power generation system according to an embodiment of the present invention may include a flow path portion through which sunlight moves, and a plurality of solar power generation units arranged in a direction in which the sunlight passes without blocking the sunlight.

[0012] The solar power generation unit may be configured as a plurality of units, and the plurality of units may be arranged along the direction in which the sunlight moves.

[0013] The flow path may include a reflective surface capable of reflecting light, so that sunlight that has passed through one solar power generation unit may be reflected and passed through again.

[0014] The solar power generation unit may be disposed separably in the flow path unit.

[0015] The solar power generation unit may include a transparent film layer having at least a non-flexible peripheral surface, and cells arranged on one side of the transparent film layer, which generate energy when receiving sunlight, and which are not arranged in a manner that closes at least all sides of the transparent film layer.

[0016] The transparent film layer may be characterized by including a frame portion having a space formed therein, and a film portion disposed within the frame portion, on which a circuit diagram is drawn, and which does not block the transmission of at least sunlight.

[0017] The flow path unit may be formed with installation sections that are a plurality of spaced-apart spaces, and the solar power generation unit may be detachably installed in the installation sections.

[0018] The solar power generation system may include an electrolysis unit that electrolyzes water to produce energy.

[0019] The solar power generation unit may be disposed on one side of the electrolysis unit, and may be operated by a power supply unit to apply a negative electrode and a positive electrode to the electrolysis unit. [Effects of the Invention]

[0020] In one embodiment of the present invention, a solar power generation unit that can transmit sunlight is arranged along the flow path of a flow path unit that can reflect sunlight, and when generating energy, more energy can be generated than in space.

[0023] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, which are not intended to limit the scope of the present invention.

[0024] In assigning reference numerals to components in each drawing, it should be noted that the same components are assigned the same numerals as much as possible even if they are displayed in different drawings. Furthermore, in describing the present invention, if it is determined that a detailed description of related known structures or functions may obscure the gist of the present invention, the detailed description thereof will be omitted.

[0025] In addition, the size and shape of components shown in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, terms specifically defined in consideration of the configuration and operation of the present invention are merely used to describe the embodiments of the present invention and do not limit the scope of the present invention.

[0026] FIG. 1 shows a solar power generation unit in a solar power generation system according to an embodiment of the present invention.

[0027] In the present invention, the solar power generation unit 100 is formed in a shape in which cells 120 are arranged on a transmissive film layer 110 as shown in Fig. 1. Here, the cells 120 may be in the form of spherical particles 120 that cannot be seen with the naked eye as shown in Fig. 1. Therefore, sunlight irradiated toward the solar power generation unit 100 can transmit through the transmissive film layer 110. Therefore, in the present invention, solar power generation can be performed even when the solar power generation unit 100 is arranged in a stacked shape.

[0028] The solar power generation unit 100 according to an embodiment of the present invention may be composed of a transparent film layer 110 and particles 120 .

[0029] The transmission film layer 110 may be made of a flexible material and may be formed into a specific shape. For example, the transmission film layer 110 may be formed into a square plate shape. The transmission film layer 110 may be transparent or opaque. However, it is preferable that the transmission film layer 110 is made of a material or materials that allow sunlight to pass through.

[0030] A circuit diagram may be printed on the transparent film layer 110. The circuit diagram may be printed on one side of the transparent film layer 110 and connected in series or parallel. In FIG. 1, a series circuit diagram is shown on the film portion 111.

[0031] The particle 120 may include a first electrode layer 121 , a second electrode layer 122 , a passivation layer 123 , a blocking layer 124 , a first connecting portion 125 , and a second connecting portion 126 .

[0032] The particle 120 is formed in a spherical shape with its bottom end exposed. That is, the particle 120 may be formed in a spherical shape by connecting other components. The particle 120 may be arranged in a shape in which the second electrode layer 122 is arranged within the first electrode layer 121. The first electrode layer 121 and the second electrode layer 122 may be formed in a shape in which the bottom side is cut horizontally. The second electrode layer 122 may be arranged within the first electrode layer 121. The first electrode layer 121 and the second electrode layer 122 may be made of different types of silicone.

[0033] As an example, the first electrode layer 121 may be N-type silicone, and the second electrode layer 122 may be P-type silicone, so that when sunlight reaches the particles 120, energy can be generated by the movement of electrons and holes.

[0034] Here, if the first electrode layer 121 is N-type silicone and the second electrode layer 122 is P-type silicone, electrons and holes will gather in the first connector 125 connected to the underside of the first electrode layer 121 and the second connector 126 arranged on the underside of the second electrode layer 122, respectively, thereby allowing electricity to flow through the circuit diagram of the transparent film layer 110.

[0035] Here, a passivation layer 123 for smooth transmission of electrons and holes may be disposed on the outer side of the first electrode layer 121. In addition, a blocking layer 124 is disposed to surround the passivation layer 123, thereby preventing reflection of sunlight.

[0036] In this way, the present invention allows invisible particles 120 to generate energy. Although the energy (electrical energy) generated by each particle 120 may be very small, the total energy generated by these particles can generate much more power (electrical energy) than conventional solar cells 120.

[0037] In addition, in the present invention, a circuit diagram is printed on the transparent film layer 110 and particles 120 are placed above the circuit diagram, so the circuit diagram can be formed in various shapes and the spacing between the particles 120 can also be adjusted.

[0038] The particle 120 may have a first connector 125 and a second connector 126. The first connector 125 may be connected to the first electrode layer 121, and the second connector 126 may be connected to the second electrode layer 122. Here, the first connector 125 may be a positive electrode or a negative electrode depending on the types of the first electrode layer 121 and the second electrode layer 122, and the second connector 126 may be the opposite electrode.

[0039] FIG. 2 is a cross-sectional view of a solar power generation system according to an embodiment of the present invention.

[0040] The solar power generation system according to an embodiment of the present invention may include a flow path unit 200 and a solar power generation unit 100 .

[0041] As described above, the solar power generation unit 100 of the present invention can generate energy using sunlight. At the same time, the solar power generation unit 100 of the present invention can transmit sunlight. Therefore, if a plurality of solar power generation units 100 are arranged along the path through which sunlight moves, the energy utilization rate for the space can be increased. In the present invention, a plurality of solar power generation units 100 may be arranged along the flow path unit 200 through which sunlight moves. Therefore, the present invention can achieve very high energy production efficiency.

[0042] FIG. 3 is a cross-sectional view of a solar power generation system according to another embodiment of the present invention.

[0043] A solar power generation system according to another embodiment of the present invention may be characterized in that a reflective surface 210 is formed on the flow path unit 200. That is, sunlight may be reflected by the reflective surface 210 as it moves through the flow path unit 200. For example, with reference to FIG. 3, sunlight may move downward, be reflected, and move upward. Therefore, sunlight that has passed through one solar power generation unit 100 may be reflected, passed through another solar power generation unit 100, and move forward.

[0044] Therefore, sunlight can travel through the flow path unit 200 multiple times and pass through the solar power generation unit 100 multiple times, thereby generating a large amount of energy. For ease of explanation, FIG. 3 shows the cells 120 positioned only on the upper surface of the transmissive film layer 110, but the present invention is not limited thereto and the cells 120 may be positioned on both surfaces.

[0045] Furthermore, the shape of the flow path portion 200 may be various shapes other than a straight line, and the reflective surface 210 may be formed on the entire inner surface of the flow path portion 200, or may be formed only on a portion of the inner surface to reflect sunlight.

[0046] FIG. 4 is a cross-sectional view of a solar power generation system according to still another embodiment of the present invention.

[0047] In another embodiment, the present invention may further include a light collecting unit 300. The light collecting unit 300 may reflect sunlight or collect sunlight toward a focal point. The light collecting unit 300 may also reflect sunlight so that the sunlight passes through the flow path unit 200.

[0048] 4, the light collecting unit 300 may be disposed on the inlet side of the flow path unit 200 and may reflect sunlight to move into the flow path unit 200. Therefore, the position of the flow path unit 200 is not limited, and the light collecting unit 300 may position the flow path unit 200 at a specific position.

[0049] The light collecting section 300 is only required to collect or reflect the sunlight and act as a guide for guiding it, and the shape of the light collecting section 300 is not important.

[0050] Although not shown in FIG. 4, it goes without saying that the reflecting surface 210 shown in FIG.

[0051] FIG. 5 is a cross-sectional view of a solar power generation system according to still another embodiment of the present invention.

[0052] In another embodiment of the present invention, the solar power generation unit 100 may be detachably disposed in the flow path unit 200. A mounting portion is formed in the flow path unit 200. For example, the mounting portion may be a gap formed in the flow path unit 200. It should be noted that the gap shown in FIG. 5 is exaggerated.

[0053] A gap may be formed in the flow path unit 200. Here, a plurality of gaps may be formed. The solar power generation unit 100 may be slid to pass through the gap and be fixed to the flow path unit 200. That is, as shown in FIG. 5, the solar power generation unit 100 may be slid from left to right and positioned in the flow path unit 200. Of course, conversely, the solar power generation unit 100 positioned in the flow path unit 200 may be slid to be removed from the flow path unit 200.

[0054] Here, a plurality of gaps in the flow path unit 200 may be arranged along the path of sunlight movement, so that the user can position or remove the solar power generation unit 100 in or from the flow path unit 200 as needed. This allows the user to control the number of solar power generation units 100 or easily replace a damaged solar power generation unit 100.

[0055] FIG. 6 shows a first example of a solar power generation unit of the solar power generation system according to the embodiment of FIG.

[0056] The transparent film layer 110 of the solar power generation unit 100 may include a frame portion 112 and a film portion 111 .

[0057] As shown in Fig. 6, the frame portion 112 may form a surrounding surface, and the film portion 111 may be disposed inside the frame portion 112. The film portion 111 may have a circuit diagram drawn thereon (not shown in Fig. 6), and the cells 120 may be disposed on one or the other surface. The frame portion 112 may be formed in a shape corresponding to the shape of the film portion 111.

[0058] For example, when the film portion 111 is formed in a rectangular shape, the frame portion 112 may also be formed in a rectangular shape. The frame portion 112 can provide rigidity to the flexible transparent film layer 110.

[0059] Therefore, the worker can install or remove the solar power generation unit 100 in the flow path unit 200 by sliding the solar power generation unit 100 including the frame unit 112 into the flow path unit 200 shown in Figure 5.

[0060] Here, the shape of the frame part 112 does not matter as long as there is a space inside so that the transparent film layer 110 can be positioned inside. Although not shown as an example, the frame part 112 may be formed in the original shape.

[0061] FIG. 7 shows a second embodiment of the solar power generation unit of the solar power generation system according to the embodiment of FIG.

[0062] In the case of the second embodiment, there is no problem if the frame portion 112 of the transparent film layer 110 is formed in a shape that surrounds the corners of the film portion 111. For example, as shown in Fig. 7, the frame portion 112 may be formed in an L-shape and surround the corners of the film portion 111. In other words, the frame portion 112 may be shaped to surround only a portion of the film portion 111.

[0063] However, the solar power generation unit 100 can be positioned in the flow path unit 200 only by placing the frame unit 112 at the installation portion of the flow path unit 200 .

[0064] As an example, assuming that the present invention is applied to a building, the light collecting unit 300 shown in Fig. 4 may be located on the roof of the building, and the floor below may be the flow path unit 200. Here, the flow path unit 200 may be an open space in the building, and the installation unit may be a gap formed in a pillar or wall. A user can install the solar power generation unit 100 of the present invention on the flow path unit 200 by sliding and positioning the frame unit 112 into the installation unit.

[0065] In the second embodiment of FIG. 7, the frame part 112 surrounds only a part of the film part 111, and the shape of the frame part 112 does not matter as long as the film part 111 receives sunlight when it is slid to the installation part.

[0066] FIG. 8 is an enlarged view of an electrolysis unit among the components of a solar power generation system according to one embodiment.

[0067] The solar power generation system according to an embodiment may further include an electrolysis unit 400 .

[0068] As described above, the electrolyzing unit 400 may generate energy by electrolyzing water using energy generated by the solar power generation system, and may supply the generated energy to the energy consuming unit 500. The electrolyzing unit 400 may be located in a set space where water and an electrolyte are mixed.

[0069] That is, the electrolysis unit 400 electrolyzes water using energy, and the generated energy can be supplied to the energy consumption unit 500 (for example, a device that uses energy to produce significant power, such as a motor, or similar type of device).

[0070] Naturally, the energy generated by the solar power generation system can be supplied to the energy consuming unit 500 .

[0071] Meanwhile, a plurality of solar power generation units 100 may be arranged on one surface of the electrolysis unit 400 of the present invention. The solar power generation unit 100 may have a basic structure as shown in Fig. 1. That is, the solar power generation unit 100 includes cells 120 (particles 120) including a first electrode layer 121 and a second electrode layer 122.

[0072] Here, the first electrode layer 121 and the second electrode layer 122 may be similar to those described in Fig. 1, and the first connector 125 and the second connector 126 may be arranged differently in the electrolyzer 400. Therefore, the positive and negative electrodes can be applied to the electrolyzer 400, respectively.

[0073] Alternatively, the first electrode layer 121 and the second electrode layer 122 may be interchangeable. That is, the connectors connected to the electrolyzer 400 are the same, but the first electrode layer 121 of one cell 120 may be N-type silicone, and the first electrode layer 121 of another cell 120 may be P-type silicone. Of course, the second electrode layer 122 located outside these may be the opposite type of silicone.

[0074] Therefore, in the present invention, when sunlight is applied to the solar power generation unit 100 disposed in the electrolysis unit 400, the electrolysis unit 400 can generate energy by applying a voltage to the positive electrode and the negative electrode. The generated energy can be supplied to the energy consumption unit 500.

[0075] FIG. 9 is an overall view of a solar power generation system according to an embodiment of the present invention.

[0076] The present invention according to one embodiment may include a solar power generation unit 100, a flow path unit 200, a light collection unit 300, an electrolysis unit 400, an energy consumption unit 500, and a storage unit 600.

[0077] The solar power generation unit 100, the flow path unit 200, the light collection unit 300, and the electrolysis unit 400 are as described above.

[0078] In the present invention, the energy generated by the solar power generation unit 100 or the energy generated by the electrolysis unit 400 can be directly supplied to the energy consumption unit 500. Therefore, the energy consumption unit 500 can consume energy. Here, the excess energy can be supplied to and stored in the storage unit 600 (for example, a battery).

[0079] As described above, the present invention can be applied to various fields, and can be installed in any space, location, etc., such as a very large building, a very small building, a livestock barn, a farm, a certain area, or a vehicle that requires electricity, as long as there is space to accommodate the flow path unit 200 and the solar power generation unit 100, and can generate energy with high efficiency.

[0080] FIG. 10 is a cross-sectional view of a solar power generation system according to still another embodiment of the present invention.

[0081] A solar power generation system according to another embodiment of the present invention may further include a moving unit 310. The moving unit 310 is movably disposed in the flow path unit 200 and can move the light collecting unit 300. The moving unit 310 can rotate around the flow path unit 200 as an axis. The moving unit 310 can tilt or rotate the light collecting unit 300.

[0082] That is, the moving unit 310 itself can move, and can also move the connected light collecting unit 300. Therefore, the tilt angle, position, etc. of the light collecting unit 300 may be changed by the moving unit 310.

[0083] Here, the energy for operating the moving unit 310 can be energy generated by the solar power generation unit 100. That is, the moving unit 310 can move the light collection unit 300 by partially utilizing the highly efficient energy generated by the solar power generation unit 100 through the light collection unit 300, thereby generating energy more efficiently. Although the present invention has been illustrated and described with reference to specific embodiments, it will be obvious to those skilled in the art that various improvements and modifications can be made to the present invention without departing from the technical spirit of the present invention as defined by the following claims.
