Description

Technology Field

More specifically, it relates to a support substrate with high economic efficiency in which a three-dimensional structure including a cut line is realized, a photovoltaic module including the same, and a method for manufacturing a photovoltaic module. Background Technology

[0003] Generally, a device that converts the energy of photons generated from the sun into electrical energy through the photoelectric effect is called a solar cell, and an assembly of two or more solar cells connected in series or parallel to a single circuit is called a photovoltaic module.

[0004] The core material of a solar cell is the light-absorbing layer that exhibits the photoelectric effect, and such materials include silicon, CIGS (Copper Indium Gallium Selenide), CdTe (Cadmium Telluride), Group III-V element composites, photoactive organic materials, perovskites, and quantum dots.

[0005] Generally, a photovoltaic system is a system that converts light energy into electrical energy using solar cells, and is used as an independent power source for general households or industries, or as an auxiliary power source connected to a commercial AC power grid.

[0006] In such solar power systems, the installation of solar panels to obtain solar energy is the most important element in the system's configuration, and these solar panels are installed either on a separately secured site or on the rooftop of a building.

[0007] Meanwhile, various solar cells applicable to buildings are being researched to improve their power efficiency, but there are difficulties in developing solar cells applicable to parts requiring transparency, such as windows.

[0008] In addition, to impart transparency to solar cells, the surface area of ​​the solar cell is adjusted (perforated type), transmittance is improved by thinning the light-absorbing layer (thin-film solar cells), the structure of the solar cell is modified (blind type, vertical type), or optical structures are used (luminescent solar concentrator, LSC).

[0009] It is unfortunate that the manufacturing process of this type of solar cell generally requires complex additional processes. For example, processes such as perforation to form the light-transmitting area, fixing and connecting the solar cell structure, and fabricating and connecting optical structures are required.

[0010] In addition, when using brittle materials such as silicone, there is a problem in that it is difficult to implement structures requiring flexibility. The problem to be solved

[0014] In addition, the present invention is intended to provide a method for manufacturing a photovoltaic module and a solar tube module in which the angle of a solar cell disposed on the upper part of a support substrate is easily adjusted by partially modifying the cut lines of the first upper cut line and the second upper cut line formed on the support substrate according to the user's needs.

FIG. 2 is an illustrative diagram for explaining a support substrate according to a first embodiment of the present invention. FIG. 3 is a front view of a support substrate according to a first embodiment of the present invention. FIG. 4 is an illustrative diagram for explaining the operation of a support substrate according to a first embodiment of the present invention.

[0045] Referring to FIGS. 1 to 4, a support substrate (10, 10') according to the first embodiment of the present invention includes a body (1000), a first cut portion (2000), and a second cut portion (3000).

[0046] The material of the support substrate (10, 10') may be one or more of the opaque materials such as acrylonitrile butadiene styrene (ABS) and polylactic acid (PLA) and the transparent materials such as thermoplastic polyurethane (TPU).

[0047] The body (1000) may be plate-shaped having a length in the first direction (X). For example, the body (1000) may be a material having flexibility and / or light transmittance. By this, the body (1000) may be stretched.

[0048] The body (1000) will be described in detail together with the unit support substrate (1100) described below.

[0049] The first incision (2000) may be formed at one end of the body (1000), and the second incision (2000) may be formed at the other end of the body (1000). For illustrative purposes, the first incision (1000) and the second incision (2000) are shown as solid lines in the drawing, but they may be dashed lines.

[0050] The first incision (2000) may include at least two first incision lines (2100) that are repeatedly formed in a second direction (Y) different from the first direction (X). Here, the second direction (Y) may be a direction perpendicular to the first direction, but is not necessarily limited thereto and may be extended as long as the embodiment of the present invention can be performed.

[0051] Additionally, the first incision line (2100) may include a first lower incision line (2110) and a first upper incision line (2120). The first lower incision line (2110) and the first upper incision line (2120) may be lines that are not interconnected.

[0052] The first lower incision line (2110) can be cut to form the first connecting part (1101).

[0053] Specifically, a single first lower cut line (2110) may include a first-1 lower cut line (2111) and a first-2 lower cut line (2112), and the first-1 lower cut line (2111) and the first-2 lower cut line (2112) may be symmetrical to each other with respect to the first line (B) in the second direction (Y).

[0054] At this time, the first lower cut line (2111) and the first-2 lower cut line (2112) may be formed so that a first connecting part (1101) is formed between the first-1 lower cut line (2111) and the first-2 lower cut line (2112).

[0055] The first-1 lower incision line (2111) may include the first-1-1 lower incision line (2111a) and the first-1-2 lower incision line (2111b).

[0056] The first-1-1 lower incision line (2111a) may be formed as a straight line in the second direction (Y) from the first-1-1 point (2101) to the first-1-2 point (2102), and the first-1-2 lower incision line (2111b) may be formed as a straight line in the first direction (X) from the first-1-2 point (2102) to the first-1-3 point (2103).

[0057] Accordingly, the 1-1 lower cut line (2111) is composed of the 1-1-1 lower cut line (2111a) and the 1-1-2 lower cut line (2111b), and may be a bent line that is interconnected at the 1-1-2 point (2102).

[0058] The first-2 lower incision line (2112) may include the first-2-1 lower incision line (2112a) and the first-2-2 lower incision line (2112b).

[0059] The first-2-1 lower cut line (2112a) may be formed as a straight line in the second direction (Y) from the first-1-4 point (2104) to the first-1-5 point (2105), and the first-2-2 lower cut line (2112b) may be formed as a straight line in the first direction (X) from the first-1-5 point (2105) to the first-1-6 point (2106).

[0060] Accordingly, the first-2 lower incision line (2112) is composed of the first-2-1 lower incision line (2112a) and the first-2-2 lower incision line (2112b), and may be a bent line that is interconnected at the first-1-5 point (2105).

[0061] The first upper cut line (2120) may have both endpoints spaced apart from the first lower cut line (2111). Here, the two endpoints refer to the first-2-1 point (2107) and the first-2-3 point (2109).

[0062] For example, point 1-2-1 (2107) may be positioned so as to be spaced apart from the lower cut line 1-1-2 (2111b) in the second direction (Y), and point 1-2-3 (2109) may be positioned so as to be spaced apart from the lower cut line 1-2-2 (2112b) in the second direction (Y). In this case, point 1-2-1 (2107) and point 1-2-3 (2109) may be positioned symmetrically with respect to the first line (B) in the second direction (Y).

[0063] The first upper incision line (2120) may include the first-1 upper incision line (2121) and the first-2 upper incision line (2122, 2122').

[0064] At this time, the first-1 upper incision line (2121) may be formed as a line connecting the first-2-1 point (2107) to the first-2-2 point (2108). The first-2-2 point (2108) may be positioned relatively closer to the second incision (3000) compared to the first-2-1 point (2107) and the first-2-3 point (2109).

[0065] Additionally, the first-2 upper incision line (2122, 2122') can be formed as a line connecting the first-2-2 point (2108) to the first-2-3 point (2109).

[0066] The first-2 upper cut line (2122, 2122') includes a first-2 curved section and a first-2 straight section. Here, the first-2 curved section and the first-2 straight section may be formed as lines connected to each other. Here, the first-2 curved section may be a curve with a starting point at the first-2-2 point (2108), and the first-2 straight section may be a straight line with an end point at the first-2-3 point (2109).

[0067] In other words, the first-2 upper cut line (2122, 2122') can be formed by a line connecting the first-2 curved section, where the starting point is the first-2-2 point (2108), and the first-2 straight section, where the ending point is the first-2-3 point (2109).

[0068] At this time, the first-2 straight section of the first-2 upper cut line (2122) may be a straight line extending in the first direction (X), but is not necessarily limited thereto, so the first-2 straight section of the first-2 upper cut line (2122') may be a straight line inclined toward the first-1 upper cut line (2121) in the first direction (X).

[0069] The second incision (3000) may include at least two second incision lines (3100) that are repeatedly formed in the second direction (Y).

[0070] The second incision line (3100) may include a second lower incision line (3110) and a second upper incision line (3120). The second lower incision line (3110) and the second upper incision line (3120) may be lines that are not connected to each other.

[0071] The second lower incision line (3110) can be cut to form the second connecting part (1102).

[0072] Specifically, a single second lower cut line (3110) includes a second-1 lower cut line (3111) and a second-2 lower cut line (3121), and the second-1 lower cut line (3111) and the second-2 lower cut line (3121) may be symmetrical to each other with respect to the first line (B) in the second direction (Y).

[0073] At this time, the second lower cut line (3111) and the second lower cut line (3112) may be formed so that a first connecting part (1101) is formed between the second lower cut line (3111) and the second lower cut line (3112).

[0074] The 2-1 lower cut line (3111) is formed as a straight line in the second direction (Y) from the 2-1-1 point (3101) to the 2-1-2 point (3102), and the 2-1-2 lower cut line (3112) can be formed as a straight line in the first direction (X) from the 2-1-2 point (3102) to the 2-1-3 point (3103).

[0075] Accordingly, the 2-1 lower cut line (3111) is composed of the 2-1-1 lower cut line (3111a) and the 2-1-2 lower cut line (3111b), and may be a bent line that is interconnected at the 2-1-2 point (3102).

[0076] The second-2nd lower incision line (3112) may include the second-2-1st lower incision line (3112a) and the second-2-2nd lower incision line (3112b).

[0077] The 2-2-1 lower cut line (3112a) may be formed as a straight line in the second direction (Y) from the 2-1-4 point (3104) to the 2-1-5 point (3105), and the 2-2-2 lower cut line (3112b) may be formed as a straight line in the first direction (X) from the 2-1-5 point (3105) to the 2-1-6 point (3106).

[0078] Accordingly, the 2-2 lower cut line (3112) is composed of the 2-2-1 lower cut line (3112a) and the 2-2-2 lower cut line (3112b), and may be a bent line that is interconnected at the 2-1-5 point (3105).

[0079] The second upper cut line (3120) may have both endpoints spaced apart from the second lower cut line (3110). Here, the two endpoints refer to the 2-2-1 point (3107) and the 2-2-3 point (3109).

[0080] For example, the 2-2-1 point (3107) may be positioned so as to be spaced apart from the 2-1-2 lower cut line (3111b) in the second direction (Y), and the 2-2-3 point (3109) may be positioned so as to be spaced apart from the 2-2-2 lower cut line (3112b) in the second direction (Y). In this case, the 2-2-1 point (3107) and the 2-2-3 point (3109) may be positioned symmetrically with respect to the first line (B) in the second direction (Y).

[0081] The second upper incision line (3120) may include the second-1 upper incision line (3121) and the second-2 upper incision line (3122, 3122').

[0082] The 2-1 upper incision line (3121) can be formed as a line connecting the 2-2-1 point (3107) to the 2-2-2 point (3108).

[0083] For illustrative purposes, the second-1 upper cut line (3121) in the drawing is shown as a straight line in the first direction (X), but it may be a curve, etc., and can be interpreted in an extended manner to the extent that there is no difficulty in carrying out the embodiment of the present invention.

[0084] The 2-2 upper incision line (3122, 3122') can be formed as a line connecting the 2-2-2 point (3108) to the 2-2-3 point (3109).

[0085] The 2-2-2 point (3108) can be positioned relatively closer to the 1st incision (2000) compared to the 2-2-1 point (3107) and the 2-2-3 point (3109).

[0086] The 2-2 upper cut line (3122, 3122') includes a 2-2 straight section and a 2-2 curved section. The 2-2 straight section and the 2-2 curved section may be formed by a line connecting them.

[0087] Here, the 2-2 curved section is a curve with a starting point at point 2-2-2 (3108), and the 2-2 straight section may be a straight line with an ending point at point 2-2-3 (3109).

[0088] In other words, the second-2 upper cut line (3122, 3122') can be formed by a connecting line of the second-2 curved section starting at the second-2-2 point (3108) and the second-2 straight section ending at the second-2-3 point (3109).

[0089] At this time, the 2-2 straight section of the 2-2 upper cut line (3122) may be a straight line extending in the 1st direction (X), but is not necessarily limited thereto, so the 2-2 straight section of the 2-2 upper cut line (3122') may be a straight line inclined toward the 2-1 upper cut line (3121) from the 1st direction (X).

[0090] At least two first incision lines (2100) and at least two second incision lines (3100) can be symmetrical in the first direction (X), respectively.

[0091] A single first incision line (2100) and a single second incision line (3100) symmetrical in the first direction (X) can form a pair of unit incision lines (2100, 3100). For example, the first incision line (2100) and the second incision line (3100) may be mutually symmetrical in the first direction (X) with respect to the second line (A).

[0092] The body (1000) may include unit support plates (1100). Here, at least two pairs of unit support plates (1100) may be formed by at least two pairs of unit cut lines (2100, 3100).

[0093] Additionally, the body (1000) may include a first adjustment part (1200), a center (1300), a second adjustment part (1400), and a fitting groove (1500).

[0094] A first adjustment portion (1200) is formed at one end of the body (1000), and a center portion (1300) may be formed between the first incision portion (2000) and the second incision portion (3000) in the first direction (X). A second adjustment portion (1400) may be formed at the other end of the body (1000).

[0095] The insertion groove (1500) can be formed between one pair of unit support plates (1100) and one pair of unit support plates (1100) adjacent in the second direction (Y) among at least two pairs of unit support plates (1100).

[0096] The insertion groove (1500) can be formed to insert and connect an object placed on the upper part of the support substrate (10, 10'), and the user can adjust the spacing according to the thickness of the object being inserted.

[0097] When the body (1000) is extended in the first direction (X) so that the distance between the first adjustment part (1200) and the second adjustment part (1300) increases, the angle formed between the upper surface of the unit support plate (1100) and the upper surface of the center (1300) can increase.

[0098] For example, a plurality of pairs of unit support plates (1100) are arranged in a plate-shaped body (1000) so as to be in contact with a first cut portion (2000) and a second cut portion (3000), and as the body (1000) is extended in a first direction (X), it may be spaced apart from the first cut portion (2000) and the second cut portion (3000), so that the angle formed by the upper surface of the unit support plate (1100) and the upper surface of the center (1300) may increase.

[0100] FIG. 5 is a perspective view for explaining a photovoltaic module according to a second embodiment of the present invention. FIG. 6 is a perspective view for explaining the operation of a photovoltaic module according to a second embodiment of the present invention. FIG. 7 is a perspective view for explaining the operation of a photovoltaic module according to a second embodiment of the present invention.

[0101] Referring to FIGS. 1 to 7 together, the solar module (100) according to the second embodiment of the present invention has a configuration of the support substrate (10, 10') and the solar cell (20) according to the first embodiment of the present invention shown in FIGS. 1 to 4 that is partially different; therefore, only the configurations that differ are described below, and detailed descriptions of duplicate reference numerals of identical configurations are omitted.

[0102] A photovoltaic module (100) according to a second embodiment of the present invention includes a support substrate (10, 10') and a solar cell (20). Here, the support substrate (10, 10') may include a body (1000), a first cut portion (2000), and a second cut portion (3000) as described above in the first embodiment.

[0103] The body (1000) is plate-shaped having a length in the first direction (X) and may include a first adjustment part (1200), a center (1300), a second adjustment part (1400), and a fitting groove (1500).

[0104] A first adjustment portion (1200) is formed at one end of the body (1000), and a center portion (1300) may be formed between the first incision portion (2000) and the second incision portion (3000) in the first direction (X). A second adjustment portion (1400) may be formed at the other end of the body (1000).

[0105] Here, the first incision (2000) may be formed at one end of the body (1000), and the second incision (3000) may be formed at the other end of the body (1000).

[0106] The solar cell (20) may be at least one and may be placed on top of the support substrate (10, 10'). For example, the solar cell (20) may be plate-shaped extending in a first direction (X).

[0107] The solar cell (20) may include a first electrode, a light absorption layer, and a second electrode and may be a crystalline silicon solar cell, but is not necessarily limited thereto.

[0108] The solar cell (20) can be coupled to the fitting groove (1500) of the body (1000). For example, one end of the solar cell (20) can be coupled to the fitting groove (1500) formed at one end of the body (1000) by the first cut portion (2000), and the other end of the solar cell (20) can be coupled to the fitting groove (1500) formed at the other end of the body (1000) by the second cut portion (3000). At this time, the solar cell (20) can be fitted into the fitting groove (1500). When one side of the solar cell (20) extends the body (1000) in the first direction (X) so that the distance between the first adjustment portion (1200) and the second adjustment portion (1400) increases, the angle formed with the upper surface of the center (1300) can increase.

[0109] Specifically, as the body (1000) is extended in the first direction (X), the angle formed by the unit support plate (1100) with the center (1300) of the body (1000) increases, and as it is contracted, the angle may decrease. Accordingly, the angle formed by one side of the solar cell (20) coupled to the fitting groove (1500) of the body (1000) with the center (1300) can be adjusted.

[0110] Here, one side of the solar cell (20) may be a side in contact with a unit support plate (1100) formed by cutting along the first-1 upper cut line (2121) and / or the second-1 upper cut line (3121), and the other side of the solar cell (20) may be a side in contact with a unit support plate (1100) formed by cutting along the first-2 upper cut line (2122, 2122') and / or the second-2 upper cut line (3122, 3122').

[0111] At this time, the solar cell (20) is supported by the side of a unit support plate (1100) formed by cutting along the first-2 upper cut line (2122, 2122') and / or the second-2 upper cut line (3122, 3122'), so that the angle formed by one side of the solar cell (20) with the upper surface of the center (1300) can be adjusted.

[0113] As described above, the first-2 upper cut line (2122, 2122') includes a first-2 curved section and a first-2 straight section, and the first-2 curved section and the first-2 straight section may be formed as a connecting line. In other words, the first-2 upper cut line (2122, 2122') may be formed as a connecting line of the first-2 curved section, which has a starting point at the first-2-2 point (2108), and the first-2 straight section, which has an ending point at the second-2-3 point (3109).

[0114] Here, the first-2 straight section of the first-2 upper cut line (2122) may be a straight line extending in, for example, the first direction (X). At this time, the angle formed by the upper surface of the solar cell (20) supported by the side of the unit support plate (1100) formed by cutting along the first-2 straight section and the center (1300) may be perpendicular.

[0115] As another example, the first-2 straight section of the first-2 upper cut line (2122') may be a straight line inclined toward the first-1 upper cut line (2121) in the first direction (X). In this case, the angle formed by the upper surface of the solar cell (20) and the center (1300), which is supported by the side of the unit support plate (1100) formed by cutting along the first-2 straight section, may be an acute angle.

[0116] The second-2 upper cut line (3122, 3122') and the second-2 straight section are mutually symmetrical with respect to the second line (A). When the second-2 straight section of the second-2 upper cut line (3122) is a straight line extending in the first direction (X), the angle formed by the upper surface of the solar cell (20) supported by the side of the unit support plate (1100) formed by cutting along the second-2 straight section and the center (1300) may be vertical.

[0117] Additionally, if the second-2 straight section of the second-2 upper cut line (3122') is a straight line inclined toward the first-1 upper cut line (3121) from the first direction (X), the angle formed between the upper surface of the solar cell (20) and the center (1300), which is supported by the side of the unit support plate (1100) formed by cutting along the second-2 straight section, may be an acute angle. Accordingly, the user can adjust the angle formed between one side of the solar cell (20) and the upper surface of the center (1300) as needed.

[0119] FIG. 8 is a step diagram for explaining a method for manufacturing a photovoltaic module according to a second embodiment of the present invention.

[0120] Referring together to FIGS. 1 to 8, a method for manufacturing a photovoltaic module according to a second embodiment of the present invention may include a cutting step (S10), a preparation step (S20), and a fitting step (S30).

[0121] The cutting step (S100) can cut a first cutting portion (2000) formed at one end of the body (1000) of a support substrate (10, 10') having a length in the first direction (X) and a second cutting portion (3000) formed at the other end of the body (1000).

[0122] In the drawing, for illustrative purposes, the first cut section (1000) and the second cut section (2000) are shown as solid lines, but they may be dashed lines.

[0123] The first incision (2000) includes at least two first incision lines (2100) that are repeatedly formed in a second direction (Y) different from the first direction (X), and the second incision (3000) may include at least two second incision lines (3100) that are repeatedly formed in the second direction (Y).

[0124] In the first direction (X), at least two first cut lines (2100) and at least two second cut lines (3100) are each symmetrical with respect to the second line (A), and a single first cut line (2100) and a single second cut line (3100) symmetrical in the first direction (X) can form a pair of unit cut lines (2100, 3100).

[0125] The first incision line (2100) may include a first lower incision line (2110) and a first upper incision line (2120). The first lower incision line (2110) may be cut to form a first connecting part (1101).

[0126] Specifically, a single first lower cut line (2110) may include a first-1 lower cut line (2111) and a first-2 lower cut line (2112), and the first-1 lower cut line (2111) and the first-2 lower cut line (2112) may be symmetrical to each other with respect to the first line (B) in the second direction (Y).

[0127] At this time, the first lower cut line (2111) and the first-2 lower cut line (2112) may be formed so that a first connecting part (1101) is formed between the first-1 lower cut line (2111) and the first-2 lower cut line (2112).

[0128] Additionally, the first-1 lower incision line (2111) may include the first-1-1 lower incision line (2111a) and the first-1-2 lower incision line (2111b).

[0129] The first-1-1 lower incision line (2111a) may be formed as a straight line in the second direction (Y) from the first-1-1 point (2101) to the first-1-2 point (2102), and the first-1-2 lower incision line (2111b) may be formed as a straight line in the first direction (X) from the first-1-2 point (2102) to the first-1-3 point (2103).

[0130] Accordingly, the 1-1 lower cut line (2111) is composed of the 1-1-1 lower cut line (2111a) and the 1-1-2 lower cut line (2111b), and may be a bent line that is interconnected at the 1-1-2 point (2102).

[0131] The first-2 lower incision line (2112) may include the first-2-1 lower incision line (2112a) and the first-2-2 lower incision line (2112b).

[0132] The first-2-1 lower cut line (2112a) may be formed as a straight line in the second direction (Y) from the first-1-4 point (2104) to the first-1-5 point (2105), and the first-2-2 lower cut line (2112b) may be formed as a straight line in the first direction (X) from the first-1-5 point (2105) to the first-1-6 point (2106).

[0133] Accordingly, the first-2 lower cut line (2112) is composed of the first-2-1 lower cut line (2112a) and the first-2-2 lower cut line (2112b), and may be a bent line that is interconnected at the first-1-5 point (2105). The first upper cut line (2120) may have both endpoints spaced apart from the first lower cut line (2111). Here, both endpoints refer to the first-2-1 point (2107) and the first-2-3 point (2109).

[0134] For example, point 1-2-1 (2107) may be positioned so as to be spaced apart from the lower cut line 1-1-2 (2111b) in the second direction (Y), and point 1-2-3 (2109) may be positioned so as to be spaced apart from the lower cut line 1-2-2 (2112b) in the second direction (Y). In this case, point 1-2-1 (2107) and point 1-2-3 (2109) may be positioned symmetrically with respect to the first line (B) in the second direction (Y).

[0135] The first upper incision line (2120) may include the first-1 upper incision line (2121) and the first-2 upper incision line (2122, 2122').

[0136] At this time, the first-1 upper cut line (2121) may be formed as a line connecting from the first-2-1 point (2107) to the first-2-2 point (2108), and the first-2 upper cut line (2122) may be formed as a line connecting from the first-2-2 point (2108) to the first-2-3 point (2109).

[0137] For illustrative purposes, the first-1 upper cut line (2121) in the drawing is shown as a straight line in the first direction (X), but it may be a curve, etc., and can be interpreted in an extended manner to the extent that there is no difficulty in carrying out the embodiment of the present invention.

[0138] Additionally, the 1-2-2 point (2108) can be positioned relatively closer to the 2nd incision (3000) compared to the 1-2-1 point (2107) and the 1-2-3 point (2109).

[0139] Additionally, the first-2 upper incision line (2122, 2122') can be formed as a line connecting the first-2-2 point (2108) to the first-2-3 point (2109).

[0140] The first-2 upper cut line (2122, 2122') includes a first-2 curved section and a first-2 straight section. Here, the first-2 curved section and the first-2 straight section may be formed as lines connected to each other. Here, the first-2 curved section may be a curve with a starting point at the first-2-2 point (2108), and the first-2 straight section may be a straight line with an end point at the first-2-3 point (2109).

[0141] In other words, the first-2 upper cut line (2122, 2122') can be formed by a line connecting the first-2 curved section, where the starting point is the first-2-2 point (2108), and the first-2 straight section, where the ending point is the first-2-3 point (2109).

[0142] At this time, the first-2 straight section of the first-2 upper cut line (2122) may be a straight line extending in the first direction (X), but is not necessarily limited thereto, so the first-2 straight section of the first-2 upper cut line (2122') may be a straight line inclined toward the first-1 upper cut line (2121) in the first direction (X).

[0143] The second incision (3000) may include at least two second incision lines (3100) that are repeatedly formed in the second direction (Y).

[0144] The second incision line (3100) may include a second lower incision line (3110) and a second upper incision line (3120). The second lower incision line (3110) and the second upper incision line (3120) may be lines that are not connected to each other.

[0145] The second lower incision line (3110) can be cut to form the second connecting part (1102).

[0146] Specifically, a single second lower cut line (3110) includes a second-1 lower cut line (3111) and a second-2 lower cut line (3112), and the second-1 lower cut line (3111) and the second-2 lower cut line (3112) may be symmetrical to each other with respect to the first line (B) in the second direction (Y).

[0147] At this time, the second lower cut line (3111) and the second lower cut line (3112) may be formed so that a first connecting part (1101) is formed between the second lower cut line (3111) and the second lower cut line (3112).

[0148] The 2-1 lower cut line (3111) is formed as a straight line in the second direction (Y) from the 2-1-1 point (3101) to the 2-1-2 point (3102), and the 2-2 lower cut line (3112) can be formed as a straight line in the first direction (X) from the 2-1-2 point (3102) to the 2-1-3 point (3103).

[0149] Accordingly, the 2-1 lower cut line (3111) is composed of the 2-1-1 lower cut line (3111a) and the 2-1-2 lower cut line (3111b), and may be a bent line that is interconnected at the 2-1-2 point (3102).

[0150] The second upper cut line (3120) may have both endpoints spaced apart from the second lower cut line (3110). Here, the two endpoints refer to the 2-2-1 point (3107) and the 2-2-3 point (3109).

[0151] For example, the 2-2-1 point (3107) may be positioned so as to be spaced apart from the 2-1-2 lower cut line (3111b) in the second direction (Y), and the 2-2-3 point (3109) may be positioned so as to be spaced apart from the 2-2-2 lower cut line (3112b) in the second direction (Y). In this case, the 2-2-1 point (3107) and the 2-2-3 point (3109) may be positioned symmetrically with respect to the first line (B) in the second direction (Y).

[0152] The second upper incision line (3120) may include the second-1 upper incision line (3121) and the second-2 upper incision line (3122, 3122').

[0153] The 2-1 upper cut line (3121) may be formed as a line connecting from the 2-2-1 point (3107) to the 2-2-2 point (3108), and the 2-2 upper cut line (3122, 3122') may be formed as a line connecting from the 2-2-2 point (3108) to the 2-2-3 point (3109).

[0154] For illustrative purposes, the second-1 upper cut line (3121) in the drawing is shown as a straight line in the first direction (X), but it may be a curve, etc., and can be interpreted in an extended manner to the extent that there is no difficulty in carrying out the embodiment of the present invention.

[0155] Additionally, the 2-2-2 point (3108) can be positioned relatively closer to the 1st incision (2000) compared to the 2-2-1 point (3107) and the 2-2-3 point (3109).

[0156] The 2-2 upper incision line (3122, 3122') can be formed as a line connecting the 2-2-2 point (3108) to the 2-2-3 point (3109).

[0157] The 2-2-2 point (3108) can be positioned relatively closer to the 1st incision (2000) compared to the 2-2-1 point (3107) and the 2-2-3 point (3109).

[0158] The 2-2 upper cut line (3122, 3122') includes a 2-2 straight section and a 2-2 curved section. The 2-2 straight section and the 2-2 curved section may be formed by a line connecting them.

[0159] Here, the 2-2 curved section is a curve with a starting point at point 2-2-2 (3108), and the 2-2 straight section may be a straight line with an ending point at point 2-2-3 (3109).

[0160] In other words, the second-2 upper cut line (3122, 3122') can be formed by a connecting line of the second-2 curved section starting at the second-2-2 point (3108) and the second-2 straight section ending at the second-2-3 point (3109).

[0161] At this time, the 2-2 straight section of the 2-2 upper cut line (3122) may be a straight line extending in the 1st direction (X), but is not necessarily limited thereto, so the 2-2 straight section of the 2-2 upper cut line (3122') may be a straight line inclined toward the 2-1 upper cut line (3121) from the 1st direction (X).

[0162] Therefore, the user can select and cut the cutting lines of the 1st-2 straight section and the 2nd-2 straight section as needed.

[0163] At least two first incision lines (2100) and at least two second incision lines (3100) can be symmetrical in the first direction (X), respectively.

[0164] A single first incision line (2100) and a single second incision line (3100) symmetrical in the first direction (X) can form a pair of unit incision lines (2100, 3100). For example, the first incision line (2100) and the second incision line (3100) may be mutually symmetrical in the first direction (X) with respect to the second line (A).

[0165] The body (1000) may include unit support plates (1100). Here, at least two pairs of unit support plates (1100) may be formed by at least two pairs of unit cut lines (2100, 3100).

[0166] The preparation step (S20) can separate the multiple pairs of unit support plates (1100) from the multiple pairs of unit cut lines (2100, 3100) formed by the first cut portion (2000) and the second cut portion (3000).

[0167] Specifically, by applying an external force to the first cut portion (2000) and the second cut portion (3000) formed in the plate-shaped body (1000), the support substrate (10, 10') can be realized in a three-dimensional solid shape.

[0168] For example, an external force can be applied so that the angle formed between the upper surface of the unit support plate (1100) and the center (1300) is greater than 80° and less than or equal to 100°.

[0169] At this time, if the angle formed between the upper surface of the unit support plate (1100) and the center (1300) is 80° or less, when the solar cell (20) is placed in the subsequent preparation step (S30), the angle formed between one surface of the solar cell (20) and the center (1300) becomes an acute angle, making it difficult to easily place the solar cell (20); and if the angle formed between the upper surface of the unit support plate (1100) and the center (1300) is 100° or more, the unit support plate (1100) may be torn due to overextension.

[0171] In the provisioning step (S30), a solar cell (20) can be placed in a fitting groove (1500) formed between a pair of adjacent unit support plates (1100) in the second direction (Y).

[0172] The solar cell (20) can be coupled to the fitting groove (1500) of the body (1000). For example, one end of the solar cell (20) can be coupled to the fitting groove (1500) formed at one end of the body (1000) by the first cut portion (2000), and the other end of the solar cell (20) can be coupled to the fitting groove (1500) formed at the other end of the body (1000) by the second cut portion (3000).

[0173] At this time, the solar cell (20) can be fitted into the fitting groove (1500). For example, the solar cell (20) can be easily fitted into the fitting groove (1500) formed between a pair of unit support plates (1100) arranged so that the angle formed by the upper surface with the center (1300) is greater than 80° and less than or equal to 100°.

[0174] Additionally, the support substrate (10, 10') may be made of a conductor, but if it is made of an insulator, multiple solar cells (20) can be electrically connected through electrodes. By doing so, the solar cells (20) can be fixed.

[0175] At this time, if the support substrate (10, 10') is an opaque material, the opaque support substrate (10, 10') may be removed to ensure light transmittance, and the solar cell (20) fixed by the electrode may maintain the angle and spacing arranged in the provision step (S30).

[0177] FIG. 9 is a step diagram for explaining a method for manufacturing a photovoltaic module according to a third embodiment of the present invention.

[0178] Referring to FIGS. 1 to 9 together, the method for manufacturing a solar module according to the third embodiment of the present invention may further include a control step (S40).

[0179] The adjustment step (S40) can adjust the degree of extension in the first direction (X) of the body (1000) to adjust the angle formed by one side of the solar cell (20) and the upper surface of the center (1300).

[0180] One side of the solar cell (20) can be extended in the first direction (X) of the body (1000) so that the distance between the first control unit (1200) and the second control unit (1400) increases, and the angle formed with the upper surface of the center (1300) can increase.

[0181] Specifically, as the body (1000) is extended in the first direction (X), the angle formed by the unit support plate (1100) with the center (1300) of the body (1000) increases, and as it is contracted, the angle may decrease. Accordingly, the angle formed by one side of the solar cell (20) coupled to the fitting groove (1500) of the body (1000) with the center (1300) can be adjusted.

[0182] Here, one side of the solar cell (20) may be a side in contact with a unit support plate (1100) formed by cutting along the first-1 upper cut line (2121) and / or the second-1 upper cut line (3121), and the other side of the solar cell (20) may be a side in contact with a unit support plate (1100) formed by cutting along the first-2 upper cut line (2122, 2122') and / or the second-2 upper cut line (3122, 3122').
