Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a photovoltaic module and a photovoltaic wall structure. Background Art

[0002] Building-integrated photovoltaic (BIPV) combines solar photovoltaic power generation with the building itself. The photovoltaic cells become part of the building, saving valuable land resources while providing local electricity supply to the building. Existing BIPV cells are mounted on building walls using a frame structure. While the frame structure provides a fixed mounting function, it is relatively limited in functionality and cannot meet the requirements of energy-efficient building facade systems. Utility Model Content

[0003] The embodiments of the present application provide a photovoltaic module and a photovoltaic wall structure, which can be installed on the wall to achieve an energy-saving building facade system that is warm in winter and cool in summer.

[0004] In a first aspect, an embodiment of the present application provides a photovoltaic module, which includes a mounting frame and a photovoltaic cell; the photovoltaic cell is arranged in the mounting frame; wherein the mounting frame includes a back panel and side panels arranged around the outer periphery of the back panel, and along a first direction, there is a first gap between the back panel and the photovoltaic cell, and an insulation space is enclosed between the back panel, the side panels and the photovoltaic cell, and an insulation layer is arranged in the insulation space, and the first direction is from the back panel to the photovoltaic cell.

[0005] In this solution, photovoltaic cells are installed in a mounting frame, and a first gap is provided between the back plate of the mounting frame and the photovoltaic cells, thereby forming an insulation space enclosed between the back plate, the side plates, and the photovoltaic cells. By providing an insulation layer in the insulation space, when the photovoltaic module is installed on the wall, the photovoltaic cells of the photovoltaic module serve the function of solar power generation. Since the photovoltaic cells are installed on the outside of the wall, the insulation layer in the mounting frame can provide insulation and heat insulation for the building wall, thereby achieving an energy-saving building facade system that is warm in winter and cool in summer. Specifically, in summer, the insulation layer in the mounting frame can provide insulation, reduce heat convection, and reduce the probability of heat from the hot air in the external environment being transferred to the wall, helping to reduce the temperature of the wall and thus improve the indoor environment. In winter, the insulation principle of the insulation layer in the mounting frame is also utilized to reduce heat convection. Compared with the external environment, the heat exchange between the hot air in the room and the cold air outside through heat convection is reduced, maintaining the indoor temperature and reducing energy loss, thereby providing insulation.

[0006] According to some embodiments of the present application, the thermal insulation layer includes at least one of asbestos, glass wool, and rock wool.

[0007] In the above technical solution, the insulation layer is made of at least one of asbestos, glass wool and rock wool. The thermal conductivity of asbestos, glass wool and rock wool is relatively low, and they have the functions of sound absorption, noise reduction and heat insulation, thereby meeting the thermal insulation requirements of the insulation layer.

[0008] According to some embodiments of the present application, the mounting frame further includes a limiting portion, which is arranged at one end of the side plate away from the back plate, and is arranged around the outer periphery of the side plate, and is used to limit the photovoltaic cell to the mounting frame.

[0009] In the above technical solution, by setting a limiting portion at one end of the side plate away from the back plate, the limiting portion can limit the photovoltaic cell, preventing the photovoltaic cell from escaping from the installation frame, and allowing the photovoltaic cell to be firmly installed on the installation frame.

[0010] According to some embodiments of the present application, the limiting portion includes a first side wall and a first flange, the first side wall extends along the first direction, one end of the first side wall is connected to an end of the side panel away from the back panel, and the other end is connected to the first flange, and the first flange extends toward the center direction of the mounting frame; along the first direction, the photovoltaic cell has a first side and a second side relative to each other, the first side is closer to the back panel than the second side, and the first flange and the side panel are respectively used to abut and limit the first side and the second side of the photovoltaic cell.

[0011] In the above technical solution, the photovoltaic cell has a first side and a second side relative to each other. By adopting the limiting part as the first side wall and the first flange, the first flange and the side plate are used to respectively abut and limit the first side and the second side of the photovoltaic cell, thereby achieving the limitation of the photovoltaic cell. The limiting part has a simple structure, and the first flange is used to achieve the blocking function of the second side of the photovoltaic cell.

[0012] According to some embodiments of the present application, along the second direction, the photovoltaic cell has a third side and a fourth side relative to each other; there is a second gap between the first side wall and the third side of the photovoltaic cell; and / or there is a third gap between the first side wall and the third side of the photovoltaic cell; the second gap and / or the third gap is filled with a first adhesive layer, and the first adhesive layer is used to bond the photovoltaic cell to the mounting frame, and the second direction is perpendicular to the first direction.

[0013] In the above technical solution, by providing a second gap between the first side wall and the third side of the photovoltaic cell; and / or providing a third gap between the first side wall and the third side of the photovoltaic cell, the second gap and / or the third gap are filled with a first adhesive layer, so that the photovoltaic cell is not only installed in the mounting frame under the limiting action of the limiting part, but the first adhesive layer can also make the photovoltaic cell bonded to the mounting frame, which not only makes the photovoltaic cell more stable when installed on the mounting frame, but the first adhesive layer can also fill the gap between the photovoltaic cell and the mounting frame, so that the photovoltaic cell is not easily displaced in the mounting frame, and the sealing is better, and external rainwater is not easily seeped into the photovoltaic cell.

[0014] According to some embodiments of the present application, a first receiving groove is formed between the first flange and the second side of the photovoltaic cell, and the first receiving groove is used to fill the functional layer, which includes at least one of a lead adsorption layer, a drying layer, and a waterproof layer.

[0015] In the above technical solution, the second side of the photovoltaic cell is the side facing the sunlight, that is, the side away from the wall. A first receiving groove is formed between the first flange and the second side of the photovoltaic cell, and the first receiving groove is filled with a functional layer. Different functional layers can be used for different types of photovoltaic cells to meet the functional requirements of the photovoltaic cells.

[0016] According to some embodiments of the present application, the mounting frame further includes a second flange, which is arranged perpendicular to the side panel. A second accommodating groove is formed between the second flange, the side panel and the first side of the photovoltaic cell. The second accommodating groove is used to fill a functional layer, and the functional layer includes at least one of a lead adsorption layer, a drying layer and a waterproof layer.

[0017] In the above technical solution, a second receiving groove is formed between the second flange and the first side of the photovoltaic cell, and the second receiving groove is filled with a functional layer. Different functional layers can be used for different types of photovoltaic cells to meet the functional requirements of the photovoltaic cells.

[0018] According to some embodiments of the present application, the photovoltaic cell is a perovskite cell, and the functional layer is a lead adsorption layer.

[0019] In the above technical solution, when the photovoltaic cell is a perovskite cell, due to the problem of lead leakage in the perovskite cell, lead generally seeps out from the first side or the second side after the periphery of the perovskite photovoltaic cell. The functional layer is selected as a lead adsorption layer. Even if the perovskite photovoltaic cell has the problem of lead leakage, the lead adsorption layer is arranged between the first flange and the second side of the photovoltaic cell, and between the second flange and the second side of the photovoltaic cell. The lead adsorption layer can adsorb the lead leaked from the inside of the photovoltaic cell, thereby reducing the risk of lead seeping out to the outside and flowing into the external environment with rainwater, thereby reducing the probability of pollution to the external environment.

[0020] According to some embodiments of the present application, the photovoltaic assembly further includes a connection assembly, and the connection assembly is used to install the installation frame on the wall.

[0021] In the above technical solution, by providing the connection components on the installation frame, the connection components can enable the installation frame to be installed on the wall, thereby realizing the function of installing the photovoltaic cell on the wall.

[0022] According to some embodiments of the present application, the connecting assembly includes a column and a first hanging member. The column is used to be installed on a wall, and the column extends along a third direction, which is the direction of gravity; the first hanging member is passed through the column along a second direction, and the side panels on both sides of the second direction of the installation frame are respectively provided with first hanging grooves. The first hanging member is used to cooperate with the first hanging groove so that the installation frame is hung on the column, and the second direction is perpendicular to the third direction.

[0023] In the above technical solution, the first hanging member is passed through the column along the second direction, and the first hanging grooves are correspondingly provided on the side panels on both sides of the second direction of the installation frame. In this way, the first hanging member is engaged with the first hanging grooves of the installation frame, so that the installation frame is hung on the column, and then the column is fixed to the wall, so that the light installation frame can be hung on the column.

[0024] According to some embodiments of the present application, along the second direction, both ends of the first hanging member are respectively used to hang and cooperate with the first hanging slots of two adjacent installation frames.

[0025] In the above technical solution, by passing the first hanging member through the column, the two ends of the first hanging member can be respectively engaged with the first hanging grooves of the two adjacent mounting frames. In this way, the first hanging member can not only fix the mounting frame on the column, but also fix the two adjacent mounting frames on the column at the same time, thereby reducing the number of first hanging members.

[0026] According to some embodiments of the present application, there are multiple first hanging members, and the multiple first hanging members are distributed at intervals along the length direction of the column.

[0027] In the above technical solution, multiple first hanging parts are spaced apart along the length direction of the column, so that each installation frame can be hung on the column through multiple first hanging parts, realizing the hanging points between the installation frame and the column, and the installation stability of the installation frame hung on the column is higher.

[0028] According to some embodiments of the present application, the connection assembly further includes a mounting member, which is used to be installed on a wall, and the mounting member is connected to the column via bolts.

[0029] In the above technical solution, the mounting piece is fixed to the wall through the setting of the mounting piece, and the mounting piece is bolted to the column, so that the column is stably mounted on one side of the wall, ensuring the installation stability of the column.

[0030] According to some embodiments of the present application, the connecting assembly includes a second hanging member, a beam and a matching member, the second hanging member is arranged on the back plate, and the second hanging member has a hanging portion; the beam is extended along the second direction, and the beam is used to be installed on the wall; the matching member is arranged on the beam, and the matching member has a second hanging groove extending along the third direction, the bottom of the second hanging groove is closed, and the second hanging member is hung on the second hanging groove through the hanging portion, the second direction is perpendicular to the third direction, and the third direction is the direction of gravity.

[0031] In the above technical solution, the crossbeam is mounted on the wall, and the mating piece is provided on the crossbeam. The mating piece has a mounting groove extending in a third direction, i.e., a vertical mounting groove. Thus, a second mounting piece is correspondingly provided on the back plate of the mounting frame. The second mounting piece is mounted from top to bottom in the second mounting groove of the mating piece via a mounting portion. During installation, the crossbeam and mating piece can be assembled first. After the crossbeam is fixed to the wall, the second mounting piece on the back plate can be directly mounted from top to bottom in the second mounting groove of the mating piece. This facilitates installation and provides high installation stability.

[0032] According to some embodiments of the present application, there are multiple second hanging parts, and the multiple second hanging parts are spaced apart along the second direction on the back plate, and the number and position of the matching parts correspond one-to-one to the number and position of the second hanging parts.

[0033] In the above technical solution, for the same installation frame, there can be multiple second hanging members. In this way, the second hanging members can be hung and matched with multiple matching members, so that the installation frame can be hung on the beam with higher stability.

[0034] In a second aspect, an embodiment of the present application further provides a photovoltaic wall structure, which includes the photovoltaic assembly of any of the aforementioned embodiments.

[0035] Other features and advantages of the present application will be described in detail in the subsequent detailed description. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] At present, the existing photovoltaic cells are installed on the wall of the building through the frame structure. The frame structure only provides the photovoltaic cells with the function of installation and fixation. The function of the frame structure is relatively simple and cannot meet the needs of the energy-saving building facade system.

[0053] Based on the above considerations, in order to achieve an energy-saving building facade system that is warm in winter and cool in summer, the present application designs a photovoltaic module, which includes a mounting frame and a photovoltaic cell; the photovoltaic cell is arranged in the mounting frame; the mounting frame includes a back panel and side panels arranged around the periphery of the back panel, and an insulation space is formed between the back panel, the side panels and the photovoltaic cell, and an insulation layer is arranged in the insulation space, and the first direction is from the back panel to the photovoltaic cell.

[0054] In such a photovoltaic module, there is a first gap between the back plate of the mounting frame and the photovoltaic cell, so that an insulation space is formed between the back plate, the side plate and the photovoltaic cell. By arranging an insulation layer in the insulation space, when the photovoltaic module is installed on the wall, since the photovoltaic cell is installed on the outside of the wall, the insulation layer in the mounting frame can play the role of heat preservation and insulation for the wall of the building, thereby realizing an energy-saving building facade system that is warm in winter and cool in summer.

[0055] This embodiment of the present application provides a photovoltaic module, please refer to Figure 1 and Figure 2 The photovoltaic module 100 includes a mounting frame 10 and a photovoltaic cell 20; the photovoltaic cell 20 is arranged in the mounting frame 10; wherein, the mounting frame 10 includes a back plate 11 and a side plate 12 arranged around the outer periphery of the back plate 11, along the first direction X, there is a first gap between the back plate 11 and the photovoltaic cell 20, and an insulation space is enclosed between the back plate 11, the side plate 12 and the photovoltaic cell 20, and an insulation layer 30 is arranged in the insulation space, and the first direction X is from the back plate 11 to the photovoltaic cell 20.

[0056] The mounting frame 10 is a frame structure that provides mounting for the photovoltaic cells 20. The backsheet 11 is a plate structure on one side of the mounting frame 10 in the thickness direction. When the photovoltaic module 100 is mounted on the wall, the backsheet 11 is closer to the wall. The side panels 12 surround the outer periphery of the backsheet 11 and connect to the backsheet 11 to form the mounting frame 10.

[0057] The shape of the installation frame 10 can be various, and can be determined according to actual conditions. Optionally, the installation frame 10 is a rectangular frame.

[0058] After the photovoltaic cell 20 is installed in the mounting frame 10, a first gap is defined between the backsheet 11 and the photovoltaic cell 20 in the first direction X. This means that there is a gap between the photovoltaic cell 20 and the backsheet 11, thereby creating an insulation space enclosed by the backsheet 11, the side panels 12, and the photovoltaic cell 20. The insulation layer 30 is disposed within the insulation space, with its two sides attached to the side panels 12 and the photovoltaic cell 20, respectively, along the first direction X. Of course, after the insulation layer 30 is installed within the insulation space, a certain gap between the insulation layer 30 and the photovoltaic cell 20 may be provided, depending on the actual situation.

[0059] The thermal insulation layer 30 refers to a thermal insulation structure composed of thermal insulation materials. The thermal insulation layer 30 can be made of a variety of materials, which can be selected according to actual conditions.

[0060] Photovoltaic cell 20 utilizes a solar photoelectric converter to convert solar energy into electrical energy. The converter is primarily composed of solar cell modules, common solar cell modules include monocrystalline silicon, polycrystalline silicon, and amorphous silicon. Once installed on the wall, photovoltaic cell 20 can efficiently convert solar radiation into DC electricity, providing green, renewable energy for the building. By converting solar energy into electricity, photovoltaic thermal insulation curtain walls can significantly reduce a building's energy consumption, reduce its reliance on traditional energy sources, and thereby reduce emissions of greenhouse gases such as carbon dioxide. This not only helps improve a building's energy efficiency, but also reduces energy waste, ultimately achieving the goal of energy conservation in buildings.

[0061] In this solution, the photovoltaic cell 20 is installed on the installation frame 10. There is a first gap between the back plate 11 of the installation frame 10 and the photovoltaic cell 20, so that an insulation space is formed between the back plate 11, the side plate 12 and the photovoltaic cell 20. By providing an insulation layer 30 in the insulation space, when the photovoltaic module is installed on the wall, the photovoltaic cell 20 of the photovoltaic module plays the role of solar power generation. Since the photovoltaic cell 20 is installed on the outside of the wall, the insulation layer 30 in the installation frame 10 can play the role of heat insulation for the wall of the building, and can realize an energy-saving building facade system that is warm in winter and cool in summer. Specifically, in summer, the insulation layer 30 in the installation frame 10 can play the role of heat insulation, reduce heat convection, and reduce the probability of heat from the hot air in the external environment being transferred to the wall, which helps to reduce the temperature of the wall and thus improve the indoor environment. In winter, the insulation principle of the insulation layer 30 in the installation frame 10 is also used to reduce heat convection. Compared with the external environment, the indoor hot air is reduced to exchange heat with the external cold air through heat convection, maintaining the indoor temperature and reducing energy loss, thereby playing a role in insulation.

[0062] According to some embodiments of the present application, the thermal insulation layer 30 includes at least one of asbestos, glass wool, and rock wool.

[0063] Asbestos, also known as asbestos board, is short for asbestos fiber cement board. It's made from asbestos, glass fiber, clay, and other materials according to a scientific formula. It has strong resistance to tension and pressure, and can withstand temperatures around 1400°C. It's used for thermal insulation, sound insulation, and general electrical insulation in boilers, steel mills, chemical plants, aluminum foundries, and more.

[0064] Glass wool is a type of fiberglass and a man-made inorganic fiber. Made by fiberizing molten glass into a cotton-like material, glass wool is a glass-like inorganic fiber with advantages such as good molding, low bulk density, low thermal conductivity, excellent thermal insulation, sound absorption, corrosion resistance, and stable chemical properties.

[0065] Rockwool, also known as rockwool board or thermal insulation decorative board, is an inorganic fiber board made from basalt through high-temperature melting. Successfully tested in June 1981, rockwool board is a new type of thermal insulation, flame retardant, and sound-absorbing material. Made from artificial inorganic fibers melted at high temperatures, rockwool board boasts lightweight, low thermal conductivity, heat absorption, and is non-flammable.

[0066] By using at least one of asbestos, glass wool, and rock wool as the insulation layer 30, the thermal conductivity of asbestos, glass wool, and rock wool is relatively low, and it has the functions of sound absorption, noise reduction, and heat insulation, thereby meeting the insulation and heat insulation requirements of the insulation layer 30.

[0067] According to some embodiments of this application, please continue to refer to Figure 2 The mounting frame 10 further includes a limiting portion 13 , which is disposed at one end of the side plate 12 away from the back plate 11 . The limiting portion 13 is disposed around the outer periphery of the side plate 12 , and is used to limit the photovoltaic cell 20 to the mounting frame 10 .

[0068] The limiting portion 13 can be a translucent panel or a limiting frame. When the limiting portion 13 is a translucent panel, the limiting portion 13 is provided on the side of the mounting frame 10 facing away from the back plate 11. The limiting portion 13 is fixedly connected to the side plate 12. To prevent the limiting portion 13 from affecting the photovoltaic cell 20 receiving sunlight, the limiting portion 13 can be made of translucent glass. The translucent glass can be selected from solar translucent glass with different light transmittances.

[0069] When the limiting portion 13 is made of translucent glass, to facilitate the assembly of the photovoltaic cell 20, the limiting portion 13 is temporarily not installed when installing the photovoltaic cell 20. After the thermal insulation layer 30 and the photovoltaic cell 20 are installed on the side panel 12 of the mounting frame 10, the translucent glass is connected to the side panel 12 to achieve the installation and fixation of the photovoltaic cell 20, completing the packaging of the photovoltaic module. The translucent glass and the side panel 12 can be detachably connected or fixedly connected. Specifically, the translucent glass panel can be installed on the side panel 12 of the mounting frame 10 by adhesive fixation.

[0070] When the limiting portion 13 is a limiting frame, the limiting portion 13 functions as a limiting barrier for the circumference of the photovoltaic cell 20. That is, along the first direction X, the orthographic projection of the limiting portion 13 falls on the projection of the photovoltaic cell 20 on the side facing away from the backsheet 11, thereby limiting the photovoltaic cell 20. Furthermore, when the mounting frame 10 is a rectangular frame, the limiting portion 13 can be divided into two parts. The limiting portion 13 on one side of the mounting frame 10 is the first part. For example, the limiting portion 13 on the top side of the mounting frame 10 is the first limiting portion 13, and the limiting portions 13 on the three directions of the mounting frame 10 other than the top side are the second limiting portions 13. The second limiting portion 13 is fixedly mounted on the side panel 12. When installing the thermal insulation layer 30 and the photovoltaic cell 20, the first limiting portion 13 is not installed first. This allows the thermal insulation layer 30 to be installed within the thermal insulation space. After the thermal insulation layer 30 is installed, the photovoltaic cell 20 is installed. When installing the photovoltaic cell 20, the photovoltaic cell 20 can be embedded into the mounting frame 10 through the opening 471 on the side of the mounting frame 10 where the first limiting portion 13 is not installed. After the photovoltaic cell 20 is embedded, the first limiting portion 13 is finally fixed to the side panel 12 to complete the packaging of the photovoltaic cell 20. The first limiting portion 13 can be fixed to the side panel 12 using screws.

[0071] By providing a limiting portion 13 at one end of the side panel 12 away from the back panel 11 , the limiting portion 13 can limit the photovoltaic cell 20 , preventing the photovoltaic cell 20 from detaching from the mounting frame 10 , and allowing the photovoltaic cell 20 to be firmly mounted on the mounting frame 10 .

[0072] According to some embodiments of this application, please continue to refer to Figure 2 The limiting portion 13 includes a first side wall 131 and a first flange 132. The first side wall 131 extends along the first direction X. One end of the first side wall 131 is connected to the end of the side plate 12 away from the back plate 11, and the other end is connected to the first flange 132. The first flange 132 extends toward the center direction of the mounting frame 10. Along the first direction X, the photovoltaic cell 20 has a first side 21 and a second side 22 relative to each other. The first side 21 is closer to the back plate 11 than the second side 22. The first flange 132 and the side plate 12 are respectively used to abut and limit the first side 21 and the second side 22 of the photovoltaic cell 20.

[0073] The first side wall 131 is disposed on the side plate 12 along the first direction X, and the first flange 132 is attached to the second side 22 of the photovoltaic cell 20. The first side 21 and the second side 22 refer to the two surfaces of the photovoltaic cell 20 in the first direction X, that is, the front and back sides of the photovoltaic cell 20.

[0074] The photovoltaic cell 20 has a first side 21 and a second side 22 relative to each other. By adopting the limiting portion 13 as a first side wall 131 and a first flange 132, the first flange 132 and the side plate 12 are respectively used to abut and limit the first side 21 and the second side 22 of the photovoltaic cell 20, thereby achieving the limitation of the photovoltaic cell 20. The limiting portion 13 has a simple structure and uses the first flange 132 to achieve the blocking function of the second side 22 of the photovoltaic cell 20.

[0075] According to some embodiments of this application, please continue to refer to Figure 2 , along the second direction Y, the photovoltaic cell 20 has a third side 23 and a fourth side 24 relative to each other; a second gap is provided between the first side wall 131 and the third side 23 of the photovoltaic cell 20; and / or a third gap is provided between the first side wall 131 and the third side 23 of the photovoltaic cell 20; the second gap and / or the third gap is filled with a first adhesive layer 31, and the first adhesive layer 31 is used to bond the photovoltaic cell 20 to the mounting frame 10, and the second direction Y is perpendicular to the first direction X.

[0076] The third side 23 and the fourth side 24 are two side surfaces of the photovoltaic cell 20 in the second direction Y. The second gap refers to the gap between the third side 23 of the photovoltaic cell 20 and the corresponding first side wall 131 of the limiting portion 13. The third gap refers to the gap between the fourth side 24 of the photovoltaic cell 20 and the corresponding first side wall 131 of the limiting portion 13.

[0077] The material of the first adhesive layer 31 can be a variety of structural adhesives. For example, the first adhesive layer 31 can be butyl adhesive, that is, butyl adhesive is used to seal the peripheral side of the photovoltaic cell 20.

[0078] Optionally, a second gap is defined between the first sidewall 131 and the third side 23 of the photovoltaic module, and a third gap is defined between the first sidewall 131 and the third side 23 of the photovoltaic module, with the first gap and the second gap being equal in distance along the second direction Y. Both the second and third gaps are filled with the first adhesive layer 31, such that both sides of the photovoltaic cell 20 in the second direction Y are bonded to the first sidewall 131 of the limiting portion 13 via the first adhesive layer 31.

[0079] By providing a second gap between the first side wall 131 and the third side 23 of the photovoltaic cell 20; and / or providing a third gap between the first side wall 131 and the third side 23 of the photovoltaic cell 20, the second gap and / or the third gap are filled with the first adhesive layer 31, so that the photovoltaic cell 20 is not only installed in the mounting frame 10 under the limiting action of the limiting portion 13, but the first adhesive layer 31 can also make the photovoltaic cell 20 bonded to the mounting frame 10, which not only makes the photovoltaic cell 20 more stable when installed on the mounting frame 10, but the first adhesive layer 31 can also fill the gap between the photovoltaic cell 20 and the mounting frame 10, so that the photovoltaic cell 20 is not easily displaced in the mounting frame 10, and the sealing is better, and external rainwater is not easily seeped into the photovoltaic cell 20.

[0080] According to some embodiments of this application, please continue to refer to Figure 2 A first receiving groove 1321 is formed between the first flange 132 and the second side 22 of the photovoltaic cell 20. The first receiving groove 1321 is used to fill the functional layer 32. The functional layer 32 includes at least one of a lead adsorption layer, a drying layer, and a waterproof layer.

[0081] The first receiving groove 1321 may be formed in the first flange 132 , and the middle portion of the first flange 132 is concave toward a side away from the photovoltaic cell 20 to form the first receiving groove 1321 .

[0082] For common types of photovoltaic cells 20, in order to improve the sealing of the photovoltaic cell 20, the functional layer 32 can be selected as a drying layer and / or a waterproof layer to prevent external rainwater from entering the interior of the photovoltaic cell 20 or the mounting frame 10 through the gap between the photovoltaic cell 20 and the first flange 132.

[0083] For the perovskite photovoltaic cell 20, the perovskite photovoltaic cell 20 has the problem of lead leakage. Lead generally seeps out from the outer peripheral side of the perovskite photovoltaic cell 20. The functional layer 32 can be used as a lead adsorption layer. In this way, even if the perovskite photovoltaic cell 20 has the problem of lead leakage, the lead adsorption layer is arranged between the first flange 132 and the second side 22 of the photovoltaic cell 20. The lead adsorption layer can adsorb the lead leaked from the photovoltaic cell 20 to prevent the lead from seeping out to the outside and flowing into the external environment with rainwater.

[0084] The second side 22 of the photovoltaic cell 20 is the side facing the sunlight, that is, the side away from the wall. A first receiving groove 1321 is formed between the first flange 132 and the second side 22 of the photovoltaic cell 20, and the first receiving groove 1321 is filled with a functional layer 32. Different functional layers 32 can be used for different types of photovoltaic cells 20 to meet the functional requirements of the photovoltaic cell 20.

[0085] According to some embodiments of this application, please continue to refer to Figure 2The mounting frame 10 further includes a second flange 14, which is arranged perpendicular to the side panel 12. A second receiving groove 143 is formed between the second flange 14, the side panel 12 and the first side 21 of the photovoltaic cell 20. The second receiving groove 143 is used to fill the functional layer 32. The functional layer 32 includes at least one of a lead adsorption layer, a drying layer and a waterproof layer.

[0086] The second accommodating groove 143 can be formed in the second flange 14, and the second flange 14 is an L-shaped structure. The second flange 14 includes a horizontal section 141 and a vertical section 142. One end of the horizontal section 141 is connected to the side panel 12, and the other end is connected to the vertical section 142. The vertical section 142 extends to the first side 21 of the photovoltaic cell 20.

[0087] By forming a second receiving groove 143 between the second flange 14 and the first side 21 of the photovoltaic cell 20 and filling the second receiving groove 143 with a functional layer 32 , different functional layers 32 can be used for different types of photovoltaic cells 20 to meet the functional requirements of the photovoltaic cell 20 .

[0088] According to some embodiments of the present application, the photovoltaic cell 20 is a perovskite cell, and the functional layer 32 is a lead adsorption layer.

[0089] Perovskite cells, also known as perovskite solar cells, are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials. They belong to the third generation of solar cells and are also called new concept solar cells.

[0090] The lead adsorption layer includes lead adsorption materials, which include natural inorganic adsorption materials, synthetic adsorption materials, and a special type of material—heavy metal total lead scavengers—that are highly effective in adsorbing and fixing lead in the environment. These scavengers primarily work by capturing and fixing lead ions in water through electrostatic adsorption, chemical complexation, or ion exchange, reducing their concentration and thus preventing environmental pollution.

[0091] When the photovoltaic cell 20 is a perovskite cell, since perovskite cells have the problem of lead leakage, lead generally seeps out from the first side 21 or the second side 22 after the outer periphery of the perovskite photovoltaic cell 20. The functional layer 32 is selected as a lead adsorption layer. Even if the perovskite photovoltaic cell 20 has the problem of lead leakage, the lead adsorption layer is arranged between the first flange 132 and the second side 22 of the photovoltaic cell 20, and between the second flange 14 and the second side 22 of the photovoltaic cell 20. The lead adsorption layer can adsorb the lead leaked from the inside of the photovoltaic cell 20, thereby reducing the risk of lead seeping out and flowing into the external environment with rainwater, thereby reducing the probability of polluting the external environment.

[0092] According to some embodiments of this application, please refer to Figure 5 The photovoltaic assembly 100 further includes a connection assembly 40 , which is used to install the mounting frame 10 on a wall.

[0093] The connection component 40 refers to a connection structure that is used to install and fix the installation frame 10 on the wall. The connection component 40 can be of various types, for example, a steel keel hanging structure can be used.

[0094] By disposing the connection component 40 on the installation frame 10, the connection component 40 can enable the installation frame 10 to be installed on the wall, thereby realizing the function of installing the photovoltaic cell 20 on the wall.

[0095] According to some embodiments of this application, please refer to Figure 3 、 Figure 4 and Figure 5 The connecting component 40 includes a column 41 and a first hanging member 42. The column 41 is used to be installed on the wall. The column 41 extends along the third direction Z, and the third direction Z is the direction of gravity. The first hanging member 42 is passed through the column 41 along the second direction Y. The side panels 12 on both sides of the second direction Y of the installation frame 10 are respectively provided with first hanging grooves 121. The first hanging member 42 is used to hang and cooperate with the first hanging grooves 121 so that the installation frame 10 is hung on the column 41, and the second direction Y is perpendicular to the third direction Z.

[0096] The column 41 refers to a column structure extending along the direction of gravity. The column 41 is fixed on the wall and serves to install the frame.

[0097] The first hanging member 42 is a hanging structure having a hanging portion 441 . The first hanging member 42 is disposed through the column 41 , and the first hanging member 42 can be fixedly connected to the column 41 .

[0098] The first hanging member 42 is passed through the column 41 along the second direction Y, and the first hanging grooves 121 are correspondingly provided on the side panels 12 on both sides of the second direction Y of the installation frame 10. In this way, the first hanging member 42 is engaged with the first hanging grooves 121 of the installation frame 10, so that the installation frame 10 is hung on the column 41. Then, the column 41 is fixed to the wall, and the light installation frame 10 can be hung on the column 41.

[0099] According to some embodiments of this application, please refer to Figure 3 、 Figure 4 and Figure 5 Along the second direction Y, both ends of the first hanging member 42 are respectively used to hang and cooperate with the first hanging grooves 121 of two adjacent installation frames 10.

[0100] Two adjacent installation frames 10 refer to two adjacent photovoltaic modules distributed along the second direction Y.

[0101] The first hanging part 42 hangs two adjacent mounting frames 10 on the same column 41. The column 41 is located between the two mounting frames 10. There is an installation gap between the two mounting frames 10. The installation gap can be filled with weather-resistant glue 50. The weather-resistant glue 50 can seal the gap between the two mounting frames 10 to prevent external rainwater from entering the gap between the two photovoltaic modules, thereby improving the sealing of the photovoltaic modules after being installed on the wall, and allowing the side of the entire photovoltaic cell 20 facing away from the wall to be in a sealed state.

[0102] By passing the first hanging member 42 through the column 41, the two ends of the first hanging member 42 can be respectively hung and cooperated with the first hanging grooves 121 of the two adjacent installation frames 10. In this way, the first hanging member 42 can not only fix the installation frame 10 on the column 41, but also fix the two adjacent installation frames 10 on the column 41 at the same time, thereby reducing the number of first hanging members 42.

[0103] According to some embodiments of this application, please refer to Figure 4 There are multiple first hanging members 42 , and the multiple first hanging members 42 are distributed at intervals along the length direction of the column 41 .

[0104] Multiple first hanging parts 42 are distributed at intervals along the length direction of the column 41, so that each installation frame 10 can be hung on the column 41 through multiple first hanging parts 42, realizing the hanging points between the installation frame 10 and the column 41, and the installation stability of the installation frame 10 hung on the column 41 is higher.

[0105] According to some embodiments of this application, please refer to Figure 3 The connection assembly 40 further includes a mounting member 43, which is used to be mounted on a wall. The mounting member 43 is connected to the column 41 by bolts.

[0106] The mounting member 43 can be a metal adapter that is fixed to the wall surface via expansion bolts. For a column 41, there are multiple mounting members 43, which together stably mount the column 41 on one side of the wall.

[0107] By setting the mounting member 43 , the mounting member 43 is fixed to the wall, and the mounting member 43 is bolted to the column 41 , so that the column 41 is stably mounted on one side of the wall, ensuring the installation stability of the column 41 .

[0108] According to some embodiments of this application, please refer to Figure 6 、 Figure 7 and Figure 8The connecting component 40 includes a second hanging component 44, a beam 45 and a matching component 46. The second hanging component 44 is arranged on the back plate 11, and the second hanging component 44 has a hanging portion 441; the beam 45 extends along the second direction Y, and the beam 45 is used to be installed on the wall; the matching component 46 is arranged on the beam 45, and the matching component 46 has a second hanging groove 461 extending along the third direction Z. The bottom of the second hanging groove 461 is closed, and the second hanging component 44 is hung on the second hanging groove 461 through the hanging portion 441. The second direction Y is perpendicular to the third direction Z, and the third direction Z is the direction of gravity.

[0109] The crossbeam 45 can be directly fixed to the wall using expansion bolts or wall connectors. Alternatively, multiple columns 41 can be pre-installed on the wall, spaced along the second direction Y. The crossbeam 45 can then be fixed to the columns 41 along the second direction Y to complete the installation of the exterior wall frame. The mating piece 46 can then be installed on the crossbeam 45. Finally, the mating piece 46 on the mounting frame 10 can be directly mounted in the second mounting slot 461 of the mating piece 46.

[0110] The mounting frame 10 is mounted on the wall via a crossbeam 45, and a matching piece 46 is disposed on the crossbeam 45. The matching piece 46 has a mounting groove extending in a third direction Z, i.e., a vertical mounting groove. Thus, a second mounting piece 44 is correspondingly disposed on the back panel 11 of the mounting frame 10. The second mounting piece 44 is mounted from top to bottom in the second mounting groove 461 of the matching piece 46 via a mounting portion 441. During installation, the crossbeam 45 and the matching piece 46 can be assembled first. After the crossbeam 45 is fixed to the wall, the second mounting piece 44 on the back panel 11 can be directly mounted from top to bottom in the second mounting groove 461 on the matching piece 46. This facilitates installation and provides high mounting stability.

[0111] According to some embodiments of the present application, there are multiple second hanging components 44, and the multiple second hanging components 44 are spaced apart along the second direction Y on the back panel 11, and the number and position of the matching components 46 correspond one-to-one to the number and position of the second hanging components 44.

[0112] For the same installation frame 10 , there can be multiple second hanging members 44 , so that the second hanging members 44 can be hung and matched with multiple matching members 46 , so that the installation frame 10 can be hung on the beam 45 with higher stability.

[0113] Of course, the connecting component 40 can also include a longitudinal beam 47, which is arranged on the back plate 11. The longitudinal beam 47 extends along the third direction Z. An opening 471 is provided on the side of the longitudinal beam 47 facing away from the back plate 11. The second hanging component 44 has a plug-in portion 442, which is inserted into the opening 471 and fixed to the longitudinal beam 47 by a locking bolt 48.

[0114] An embodiment of the present application further provides a photovoltaic wall structure, which includes the photovoltaic components of any of the aforementioned embodiments.

[0115] In some embodiments, please refer to Figures 1 to 8 The photovoltaic module includes a mounting frame 10 and a photovoltaic cell 20; the photovoltaic cell 20 is mounted on the mounting frame 10; the mounting frame 10 includes a back panel 11 and side panels 12 disposed around the periphery of the back panel 11. Along a first direction X, a first gap is defined between the back panel 11 and the photovoltaic cell 20. An insulation space is enclosed between the back panel 11, the side panels 12, and the photovoltaic cell 20, and an insulation layer 30 is disposed within the insulation space. The first direction X is from the back panel 11 toward the photovoltaic cell 20. The mounting frame 10 also includes a stopper 13, which is disposed at an end of the side panel 12 away from the back panel 11. The stopper 13 is disposed around the periphery of the side panel 12 and is used to limit the photovoltaic cell 20 within the mounting frame 10. The limiting portion 13 includes a first side wall 131 and a first flange 132. The first side wall 131 extends along the first direction X. One end of the first side wall 131 is connected to the end of the side plate 12 away from the back plate 11, and the other end is connected to the first flange 132. The first flange 132 extends toward the center direction of the mounting frame 10. Along the first direction X, the photovoltaic cell 20 has a first side 21 and a second side 22 relative to each other. The first side 21 is closer to the back plate 11 than the second side 22. The first flange 132 and the side plate 12 are respectively used to abut and limit the first side 21 and the second side 22 of the photovoltaic cell 20.

[0116] By providing an insulation layer 30 within the insulation space, when the photovoltaic module is installed on the wall, the photovoltaic cells 20 of the photovoltaic module function as solar power generation. Since the photovoltaic cells 20 are installed on the outside of the wall, the insulation layer 30 within the mounting frame 10 can provide insulation and heat insulation for the building wall, thereby achieving an energy-saving building facade system that is warm in winter and cool in summer. The limiting portion 13 can limit the photovoltaic cell 20, preventing the photovoltaic cell 20 from escaping from the mounting frame 10 and ensuring that the photovoltaic cell 20 is firmly installed on the mounting frame 10. By adopting the limiting portion 13 as a first side wall 131 and a first flange 132, the first flange 132 and the side plate 12 are respectively used to abut and limit the first side 21 and second side 22 of the photovoltaic cell 20, thereby achieving the limitation of the photovoltaic cell 20. The limiting portion 13 has a simple structure, and the first flange 132 is used to achieve the blocking function of the second side 22 of the photovoltaic cell 20.

[0117] In some embodiments, along the second direction Y, the photovoltaic cell 20 has a third side 23 and a fourth side 24 that oppose each other. A second gap is defined between the first sidewall 131 and the third side 23 of the photovoltaic cell 20, and / or a third gap is defined between the first sidewall 131 and the third side 23 of the photovoltaic cell 20. The second gap and / or the third gap are filled with a first adhesive layer 31, which is used to bond the photovoltaic cell 20 to the mounting frame 10. The second direction Y is perpendicular to the first direction X. A first receiving groove 1321 is formed between the first flange 132 and the second side 22 of the photovoltaic cell 20. The first receiving groove 1321 is used to fill the functional layer 32. The photovoltaic cell 20 is a perovskite cell, and the functional layer 32 includes a lead adsorption layer. The mounting frame 10 also includes a second flange 14, which is disposed perpendicular to the side panel 12. A second receiving groove 143 is formed between the second flange 14, the side panel 12, and the first side 21 of the photovoltaic cell 20. The second receiving groove 143 is used to fill the functional layer 32.

[0118] A second gap is defined between the first sidewall 131 and the third side 23 of the photovoltaic cell 20; and / or a third gap is defined between the first sidewall 131 and the third side 23 of the photovoltaic cell 20. The second gap and / or the third gap are filled with a first adhesive layer 31. Thus, the photovoltaic cell 20 is not only mounted within the mounting frame 10 under the restraining action of the restraining portion 13, but the first adhesive layer 31 also allows the photovoltaic cell 20 to adhere to the mounting frame 10, increasing the stability of the photovoltaic cell 20 mounted on the mounting frame 10. Furthermore, the first adhesive layer 31 fills the gap between the photovoltaic cell 20 and the mounting frame 10, preventing the photovoltaic cell 20 from shifting within the mounting frame 10 and providing improved sealing, preventing external rainwater from penetrating into the photovoltaic cell 20. A first receiving groove 1321 is formed between the first flange 132 and the second side 22 of the photovoltaic cell 20, and the first receiving groove 1321 is filled with a functional layer 32. When the photovoltaic cell 20 is a perovskite cell, since perovskite cells have the problem of lead leakage, lead generally seeps out from the first side 21 or the second side 22 after the outer periphery of the perovskite photovoltaic cell 20. The functional layer 32 is selected as a lead adsorption layer. Even if the perovskite photovoltaic cell 20 has the problem of lead leakage, the lead adsorption layer is arranged between the first flange 132 and the second side 22 of the photovoltaic cell 20, and between the second flange 14 and the second side 22 of the photovoltaic cell 20. The lead adsorption layer can adsorb the lead leaked from the inside of the photovoltaic cell 20, thereby reducing the risk of lead seeping out and flowing into the external environment with rainwater, thereby reducing the probability of polluting the external environment.

[0119] In some embodiments, the photovoltaic module further includes a connection assembly 40, which includes a column 41 and a first mounting member 42. The column 41 is configured to be mounted on a wall and extends along a third direction Z, which is the direction of gravity. The first mounting member 42 extends through the column 41 along a second direction Y. The side panels 12 of the mounting frame 10 on either side of the second direction Y are provided with first mounting grooves 121. The first mounting members 42 are configured to engage with the first mounting grooves 121, allowing the mounting frame 10 to be mounted on the column 41. The second direction Y is perpendicular to the third direction Z. Along the second direction Y, the ends of the first mounting member 42 are configured to engage with the first mounting grooves 121 of two adjacent mounting frames 10. There are multiple first mounting members 42, spaced apart along the length of the column 41. The connection assembly 40 further includes a mounting member 43, configured to be mounted on a wall and connected to the column 41 via bolts.

[0120] The first hanging member 42 is passed through the column 41 along the second direction Y, and first hanging grooves 121 are correspondingly provided on the side panels 12 on both sides of the installation frame 10 in the second direction Y. In this way, the first hanging member 42 is hung and matched with the first hanging grooves 121 of the installation frame 10, so that the installation frame 10 is hung on the column 41. Then, the column 41 is fixed to the wall, and the installation frame 10 is hung on the column 41. The two ends of the first hanging member 42 can respectively hang and match with the first hanging grooves 121 of two adjacent installation frames 10. In this way, the first hanging member 42 can not only fix the installation frame 10 to the column 41, but also simultaneously fix two adjacent installation frames 10 to the column 41, thereby reducing the number of first hanging members 42. Multiple first hanging members 42 are spaced apart along the length of the column 41, so that each mounting frame 10 can be hung on the column 41 via the multiple first hanging members 42, achieving the hanging points between the mounting frame 10 and the column 41, and the mounting stability of the mounting frame 10 hung on the column 41 is improved. The mounting member 43 is fixed to the wall, and the mounting member 43 is bolted to the column 41, thereby stably mounting the column 41 on one side of the wall and ensuring the installation stability of the column 41.

[0121] In some embodiments, the connecting assembly 40 includes a second hanging member 44, a crossbeam 45, and a mating member 46. The second hanging member 44 is disposed on the back panel 11 and has a hanging portion 441. The crossbeam 45 extends along the second direction Y and is used for wall mounting. The mating member 46 is disposed on the crossbeam 45 and has a second hanging slot 461 extending along the third direction Z. The bottom of the second hanging slot 461 is closed, and the second hanging member 44 is hung in the second hanging slot 461 via the hanging portion 441. The second direction Y is perpendicular to the third direction Z, which is the direction of gravity. There are multiple second hanging members 44, and the multiple second hanging members 44 are spaced apart on the back panel 11 along the second direction Y. The number and position of the mating members 46 correspond one-to-one with the number and position of the second hanging members 44.

[0122] The crossbeam 45 is mounted on the wall, and the mating member 46 is provided on the crossbeam 45. The mating member 46 has a mounting groove extending in the third direction Z, i.e., a vertical mounting groove. Thus, a second mounting member 44 is correspondingly provided on the back panel 11 of the mounting frame 10. The second mounting member 44 is mounted from top to bottom in the second mounting groove 461 of the mating member 46 via the mounting portion 441. During installation, the crossbeam 45 and the mating member 46 can be assembled first. After the crossbeam 45 is fixed to the wall, the second mounting member 44 on the back panel 11 can be directly mounted from top to bottom in the second mounting groove 461 of the mating member 46. This facilitates installation and provides high installation stability. For the same mounting frame 10, there can be multiple second mounting members 44. By mounting the second mounting member 44 in conjunction with multiple mating members 46, the mounting frame 10 can be mounted on the crossbeam 45 with greater stability.
