Description

Manufacturing and manufacturing method of balloon solar modules

[0001] The present invention relates to a solar power generation device.

[0002] In particular, the present invention relates to a solar power generation device that can be portable and used outdoors.

[0003] As the importance of green energy grows, interest is growing in solar power generation, which generates energy without producing pollutants. Solar power generation typically involves arranging n-type and p-type semiconductors to generate electrons and holes in response to light, creating a potential difference to generate energy.

[0004] As solar energy is infinite, solar power generation is expected to have limitless potential, but technological improvements in solar power generation are slow due to the limitations of solar power generation.

[0005] The biggest problem in solar power generation is space constraints.

[0006] Because solar power generation isn't very efficient, cells are connected to form modules, which are then connected to form arrays. However, arrays are very long in both width and height, requiring a large space for installation, which presents a limitation.

[0007] Additionally, solar power generation requires sunlight to shine onto the cells, requiring a sunny location. Therefore, it cannot be utilized in locations where sunlight is blocked by trees, such as forests.

[0008] It is believed that innovative technological improvements in solar power generation will be difficult unless the problem of space constraints is resolved.

[0009] The present invention aims to provide a solar power generation device that is highly versatile and free from the aforementioned spatial constraints. Furthermore, the present invention aims to provide a portable solar power generation device by reducing the size of the device, which would otherwise cause spatial constraints.

[0010] A solar power generation device according to one embodiment may include a substrate portion that can be positioned in the air when a low-density gas is positioned therein, and a solar power generation body that is disposed on one surface of the substrate portion and receives sunlight to generate energy.

[0011] The above substrate portion may be characterized by being arranged in a shape that closes the space inside to prevent the low-density gas from leaking out.

[0012] The above substrate portion may be characterized by being transparent.

[0013] The above substrate portion may be composed of a plurality of substrate piece portions, and one surface of the substrate piece portions that comes into contact with each other may be characterized in that a rotatable connecting portion is positioned.

[0014] It may be characterized in that a first connecting portion is formed on one of the plurality of substrate pieces, and a second connecting portion is formed on one of the substrate pieces positioned opposite the first connecting portion, so that the first connecting portion and the second connecting portion can be connected and fixed.

[0015] The above substrate portion may be characterized in that a gas injection portion is formed through which gas moves in one direction.

[0016] It may be characterized in that a terminal fixing part is formed on one side of the above substrate part, one side of which is connected to a battery and the other side of which is connected to the substrate part, so as to transfer the generated energy to the battery and fix the position of the substrate part.

[0017] According to one embodiment of the present invention, the solar power generation device can be positioned in the air, so it can be free from spatial constraints. Furthermore, the solar power generation device of the present invention can be portable because it is small in size.

[0022] The present invention is susceptible to various modifications and embodiments. Specific embodiments are illustrated and described in detail in the detailed description. However, this is not intended to limit the present invention to specific embodiments, but rather to encompass all modifications, equivalents, and alternatives falling within the spirit and technical scope of the present invention.

[0023] The terminology used herein is merely used to describe specific embodiments and is not intended to limit the present invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In the present invention, it should be understood that the terms "comprise" or "have" are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, but do not exclude in advance the possibility of the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. Please note that, where possible, identical components are represented by identical reference numerals throughout the drawings. Furthermore, detailed descriptions of well-known functions and configurations that may obscure the gist of the present invention will be omitted. For the same reason, some components in the attached drawings are exaggerated, omitted, or schematically depicted.

[0025] Figure 1 illustrates a solar power generation device according to a first embodiment of the present invention.

[0026] FIG. 2 illustrates a substrate piece portion and a solar power generation body, which are part of a substrate portion of a solar power generation device according to one embodiment of the present invention.

[0027] Minimizing the size of a solar power generation device requires high solar power generation efficiency. The present invention can generate a very high energy output per unit area due to its spherical, microscopic solar power generation element (200). Furthermore, the present invention can generate three-dimensional energy, unlike conventional solar power generation devices that generate energy in a two-dimensional space, due to the transparency of the substrate (100). Therefore, the present invention can generate a very high energy output.

[0028] Furthermore, to avoid spatial constraints, the solar power generation device can be positioned in the air, rather than on the ground. However, this requires lightweight solar power generation devices. Lightness requires simple components, and this simplicity can be achieved through the aforementioned maximization of energy efficiency.

[0029] The solar power generation device of the present invention that makes this possible can be composed of a substrate (100) and a solar power generation body (200).

[0030] The substrate portion (100) is formed by combining the substrate piece portion (110) and can include almost all of the characteristics of the substrate piece portion (110).

[0031] The substrate piece (110) may be transparent or opaque. It is preferable that the substrate piece (110) be made of a material or substance that allows light to pass through. The substrate piece (110) arranged in a predetermined shape is collectively referred to as the substrate piece (100).

[0032] A circuit diagram may be printed on the substrate piece portion (110). The circuit diagram may be printed on one side of the substrate piece portion (110) and connected in series or parallel. (Fig. 2 illustrates a serial circuit diagram drawn on the substrate piece portion (110).)

[0033] A solar power generator (200) may include a first electrode layer (210), a second electrode layer (220), a passivation layer (230), a prevention layer (240), a first connection portion (250), and a second connection portion (260).

[0034] The solar power generator (200) is formed in a spherical shape with an exposed bottom. That is, the solar power generator (200) can be formed in a spherical shape by connecting other components. The solar power generator (200) can be arranged in a shape in which a second electrode layer (220) is arranged on the inside of a first electrode layer (210). The first electrode layer (210) and the second electrode layer (220) can be formed in a shape in which the bottom is cut horizontally. In addition, the second electrode layer (220) can be arranged on the inside of the first electrode layer (210). However, this arrangement may not be a problem even if it is reversed as shown in FIG. 2. The first electrode layer (210) and the second electrode layer (220) can be different types of silicon.

[0035] For example, the first electrode layer (210) may be N-type silicon, and the second electrode layer (220) may be P-type silicon. Therefore, when light reaches the solar power generator (200), energy can be generated through the movement of electrons and holes.

[0036] Here, if the first electrode layer (210) is N-type silicon and the second electrode layer (220) is P-type silicon, electrons and holes are gathered into the first connection portion (250) connected to the lower side of the first electrode layer (210) and the second connection portion (260) arranged on the lower side of the second electrode layer (220), respectively, and thereby electricity can flow through the circuit of the substrate piece portion (110).

[0037] Here, a passivation layer (230) may be placed on the outer side of the first electrode layer (210) to ensure smooth transmission of electrons and holes. In addition, a prevention layer (240) may be placed to surround the passivation layer (230) to prevent reflection of light.

[0038] In this way, the present invention enables solar power generators (200) that cannot be seen with the naked eye to produce energy. While the energy (electrical energy) generated by each of these solar power generators (200) may be very small, when combined, the energy generated can generate significantly more energy than the cells of previous photovoltaic systems.

[0039] In addition, since the present invention has a circuit diagram printed on the substrate piece (110) and a solar power generator (200) placed on the upper side of the circuit diagram, the circuit diagram can be formed in various forms and the spacing between the solar power generators (200) can also be adjusted.

[0040] And, a first connection part (250) and a second connection part (260) may be arranged in the solar power generator (200). The first connection part (250) may be connected to the first electrode layer (210), and the second connection part (260) may be connected to the second electrode layer (220). Here, the first connection part (250) may be a + electrode or a - electrode depending on the types of the first electrode layer (210) and the second electrode layer (220), and the second connection part (260) may be an opposite electrode.

[0041] In this way, the present invention has the characteristic of being highly usable due to the small size of the solar power generator (200), the space formed between the solar power generators (200), and the flexible substrate piece (110) having transparency.

[0042] The solar power generation device of the present invention may include a substrate portion (100), a gas injection portion (350), a gas removal portion (360), a solar power generation body (200), and a terminal fixing portion (500).

[0043] The substrate portion (100) is arranged in the shape of a specific figure. For example, the substrate portion (100) may be shaped like a rectangular parallelepiped by the substrate piece portion (110) formed as a rectangular parallelepiped. However, the present invention is not limited thereto, and the substrate portion (100) may be arranged in a form of forming various shapes such as a tetrahedron or a sphere. That is, the substrate portion (100) may be arranged to form a closed figure. According to this arrangement of the substrate portion (100), a closed space may be formed by the substrate portion (100). The substrate portion (100) is formed of a transparent film. In addition, the characteristics of the substrate portion (100) may be characteristics when the substrate piece portion (110) having the above-described characteristics is combined and manufactured.

[0044] A gas injection unit (350) may be formed on one side of the substrate portion (100). The gas injection unit (350) may have a channel formed in the longitudinal direction of the valve, and one end may be formed in a sealed shape. When a gas injection needle is positioned in the channel of the gas injection unit (350) and gas is supplied, gas may be positioned in the space closed by the substrate portion (100).

[0045] Here, the gas is preferably a gas with a lower density than air. For example, the gas may be He. If a low-density gas fills the space enclosed by the substrate (100), the present invention can be positioned in the air.

[0046] The gas removal unit (360) may be located on the other side of the substrate unit (100).

[0047] The gas removal unit (360) may have a channel formed along the longitudinal direction. The gas removal unit (360) may include a blocking unit. The blocking unit of the gas removal unit (360) may be formed to be able to open and close the channel. Therefore, when the blocking unit is removed, the space closed by the substrate unit (100) can be communicated with the outside with respect to the substrate unit (100). Therefore, low-density gas located in the space closed by the substrate unit (100) can be removed.

[0048] A solar power generator (200) may be placed on one side of the substrate portion (100). A circuit diagram is drawn on one side of the substrate piece portion (110), and the solar power generator (200) may be placed along the circuit diagram of the substrate piece portion (110). When the solar power generator (200) receives sunlight, it generates energy and moves along the circuit diagram.

[0049] A terminal fixing portion (500) can be formed in conjunction with the circuit diagram of the substrate portion (100). The terminal fixing portion (500) can be composed of a first terminal fixing portion (510) and a second terminal fixing portion (520).

[0050] The first terminal fixing part (510) is connected to the circuit diagram of the substrate piece part (110), and the second terminal fixing part (520) can be connected to the battery (600). A diode can be positioned on the first terminal fixing part (510). Therefore, energy can flow in only one direction and be transferred to the battery (600). In addition, the terminal fixing part (500) can fix the position of the present invention located in the air, and at the same time, allow energy to be transferred to the battery (600) and stored.

[0051] In this way, the solar power generation device of the present invention can be positioned in the air and generate solar power.

[0052] Figure 3 illustrates a solar power generation device according to a second embodiment of the present invention.

[0053] The present invention according to the second embodiment will be described with reference to FIG. 3. In the present invention, a hinge connection can be established between the substrate piece portion (110) and the substrate piece portion (110). (When describing the second embodiment, unnecessary components among the components described in the first embodiment have been deleted.)

[0054] The substrate piece portion (110) is formed in a rectangular shape, and the substrate piece portions (110) can be arranged to form a rectangular parallelepiped. Therefore, one surface of one substrate piece portion (110) and the other surface of another substrate piece portion (110) can be in contact with each other. A rotational connecting portion (400) can be arranged at the portion where the substrate piece portions (110) and the substrate piece portions (110) are in contact with each other.

[0055] The rotational connecting portion (400) can rotatably connect two substrate pieces (110). Therefore, the substrate pieces (110) can rotate with respect to each other.

[0056] Meanwhile, the substrate piece portion (110) must block the internal space from the outside due to its arrangement, which can be achieved by the first joint portion (451) and the second joint portion (452).

[0057] The part indicated by A-A' in Fig. 3 is a cross-sectional view of that part.

[0058] Based on Fig. 3, a first connecting portion (451) is arranged on the lower side of the substrate piece portion (110) arranged vertically from the front side, and a second connecting portion (452) is arranged on the left side of the substrate piece portion (110) arranged horizontally from the lower side.

[0059] The first connecting portion (451) may have a 'ㄷ' shaped groove formed, and the second connecting portion (452) may have a rectangular parallelepiped shaped protrusion formed into the groove of the first connecting portion (451). The second connecting portion (452) may be inserted into the groove of the first connecting portion (451), so that the substrate piece portions (110) may be sealed against each other.

[0060] In addition, a sealing material for sealing may be placed in the groove of the first connecting portion (451). Therefore, the gap that occurs when the first connecting portion (451) and the second connecting portion (452) are connected can be sealed.

[0061] In this way, the present invention can be used in a portable manner by forming the substrate portion (100) into a specific closed-shaped shape or separating it.

[0062] That is, the present invention can perform solar power generation by rotating the rotating connection part (400), finally fixing the first connection part (451) and the second connection part (452), and then injecting low-density gas into the gas injection part (350). Then, when use is finished, the combined first connection part (451) and second connection part (452) are separated, and the rotating connection part (400) is rotated to reduce the volume. Therefore, the solar power generation device can be easily moved with portability.

[0063] Figure 4 illustrates a solar power generation device according to a third embodiment of the present invention.

[0064] According to the third embodiment, the solar power generation device of the present invention may include an auxiliary fastening member (700). The auxiliary fastening member (700) may collectively refer to a circular ring with an empty interior at a corner side of the substrate part (100) and a hook inserted into the ring to impede movement of the substrate part (100).

[0065] The hook is connected to a wire having a long length, and although not shown, some of it can be fixed to the ground. The auxiliary fastening member (700) can prevent the substrate member (100) from being dislodged from the set position.

[0066] Above, one embodiment of the present invention has been described, but a person having ordinary skill in the art will be able to modify and change the present invention in various ways by adding, changing, deleting or adding components, etc., within the scope that does not depart from the spirit of the present invention described in the claims, and this will also be considered to be included within the scope of the rights of the present invention.
