[0032] The present application provides a photovoltaic component.

[0033] Please refer to Figures 1 to 4 In an embodiment of the present application, the photovoltaic component includes an outer glass 10, a main frame 20, a photovoltaic assembly 30 and an outer frame 40. One side of the main frame 20 is connected to one side of the outer glass 10. The photovoltaic assembly 30 is connected to the side of the main frame 20 away from the outer glass 10. The outer frame 40 is connected to the side of the photovoltaic assembly 30 away from the main frame 20, and is detachably connected to the main frame 20.

[0034] The outer layer glass 10 as the outermost layer of the photovoltaic component plays a role of protecting the internal structure and transmitting light. It adopts a high-strength and high-transmittance glass material, can effectively resist the erosion of natural factors such as wind and sand, rain and snow from the outside world, and at the same time, ensure sufficient light transmission, so as to provide sufficient light energy for the photoelectric conversion of the photovoltaic module 30. The main frame 20 is the core support structure of the photovoltaic component, which is usually made of high-strength metal material. One side of the main frame 20 is closely connected with the outer layer glass 10, and provides stable support for the outer layer glass 10, so that the outer layer glass 10 can maintain flatness and stability under various environmental conditions. The main frame 20 is provided with a sealing rubber ring 50 groove on the side away from the outer layer glass 10, which is used for installing the sealing rubber ring 50 and enhancing the air tightness and waterproofness of the component. The photovoltaic module 30 is the core power generation part of the photovoltaic component, which can effectively convert sunlight into electrical energy. During installation, the photovoltaic module 30 is connected to the side of the main frame 20 away from the outer layer glass 10 by adsorption, which not only ensures the stability of the connection, but also facilitates the disassembly and replacement of the module. The outer layer frame 40 includes a horizontal frame 41 and a vertical frame, which abuts against the side of the photovoltaic module 30 away from the main frame 20, and is connected with the main frame 20 through a detachable connection mode such as screw. The outer layer frame 40 not only plays a role of protecting the photovoltaic module 30, but also provides a neat and beautiful appearance for the entire photovoltaic component. The detachable design makes it convenient to disassemble the frame and perform internal operation when the photovoltaic module 30 needs to be repaired or replaced.

[0035] During normal use, sunlight transmitted through the outer layer glass 10 irradiates on the perovskite photovoltaic module 30, and the photovoltaic module 30 converts light energy into electrical energy, which is led out to the BIPV total circuit through the junction box to provide power for the building. The outer layer frame 40 protects the photovoltaic module 30 from external collision and damage, and at the same time, provides a neat and beautiful appearance for the entire component.

[0036] The design of the independent outer layer frame 40 makes it more convenient to repair / inspect the circuit. When the circuit needs to be repaired or inspected, only the lower horizontal frame 41 needs to be disassembled, so that the junction box and the circuit connection can be inspected and replaced, without the need to disassemble the entire component on a large scale, which greatly improves the repair efficiency, reduces the risk of damage to other parts of the component during the repair process, and increases the safety of the component.

[0037] The photovoltaic component of the utility model makes the BIPV component replace the photovoltaic module 30 at any time as needed during the entire service life of the building, solves the problem that the service life of the traditional BIPV module is shorter than the design life of the building, makes the BIPV component have the same service life as the building design, realizes the detachable replacement of the photovoltaic module 30 in the photovoltaic component, and further prolongs the service life of the photovoltaic component on the building.

[0038] In an embodiment, referring to Figures 1 to 4 The photovoltaic component further comprises a sealing gasket 50, which is arranged between the main frame 20 and the photovoltaic assembly 30.

[0039] The sealing gasket 50 is a key component in the photovoltaic component for enhancing air tightness and waterproofness. It is usually made of rubber material with good elasticity and weather resistance, which can tightly fit between the main frame 20 and the photovoltaic assembly 30, forming a sealed barrier. The groove design of the sealing gasket 50 on the main frame 20 ensures its accurate and fixed installation position, effectively preventing displacement caused by vibration or external force.

[0040] The sealing gasket 50 is arranged between the main frame 20 and the photovoltaic assembly 30, and through its elasticity and sealing grease, it forms a very high air tightness. This high air tightness not only effectively isolates the outside air and moisture, but also makes the component have multiple functions such as heat insulation, sound insulation, frost prevention, and dew prevention. The heat insulation function can reduce heat transfer and reduce the energy consumption of the building; the sound insulation function can reduce the interference of external noise and provide a more comfortable indoor environment; the frost and dew prevention function can prevent water vapor condensation and prolong the service life of the component.

[0041] The tight fit and elastic deformation of the sealing gasket 50 ensure the stable installation of the photovoltaic assembly 30 under various environmental conditions. Even under vibration or external force, the sealing gasket 50 can maintain its sealing performance and prevent the infiltration of air and moisture, thereby improving the stability and reliability of the photovoltaic component.

[0042] In an embodiment, referring to Figures 1 to 4 The sealing gasket 50 forms a hollow cavity 50a with the main frame 20 and the photovoltaic assembly 30, and the main frame 20 is provided with an air hole 50b that communicates with the hollow cavity 50a, and the air hole 50b is used for the vacuum device to insert and vacuum, so that the photovoltaic assembly 30 is adsorbed and connected to the side of the main frame 20 away from the outer glass 10.

[0043] The hollow cavity 50a is a sealed space enclosed by the sealing gasket 50, the main frame 20 and the photovoltaic assembly 30. After vacuumizing, this space can form a negative pressure, so that the photovoltaic assembly 30 is tightly adsorbed on the main frame 20, enhancing the stability of the connection. The design of the hollow cavity 50a not only improves the air tightness and heat insulation performance of the component, but also provides a stable installation environment for the photovoltaic assembly 30.

[0044] The sealing rubber ring 50 and the main frame 20 and the photovoltaic module 30 form a hollow cavity 50a, which is vacuumed through the air hole 50b on the main frame 20, forming a very high airtightness. This high airtightness not only effectively isolates the outside air and moisture, but also makes the component have the functions of heat insulation, sound insulation, frost prevention, dew prevention and other functions. The negative pressure design of the hollow cavity 50a makes the photovoltaic module 30 tightly adsorbed on the main frame 20, enhancing the stability of the connection. Even under the action of vibration or external force, the sealing rubber ring 50 can maintain its sealing performance, preventing the infiltration of air and moisture, thereby improving the stability and reliability of the photovoltaic component.

[0045] In an embodiment, referring to Figures 1 to 4 , the side of the main frame 20 facing the photovoltaic module 30 is provided with a mounting groove 20a, and the sealing rubber ring 50 is mounted in the mounting groove 20a and protrudes from the groove of the mounting groove 20a to elastically abut the photovoltaic module 30.

[0046] The mounting groove 20a is a specially designed groove on the main frame 20 for mounting the sealing rubber ring 50. The size and shape of the mounting groove 20a match the sealing rubber ring 50, ensuring that the sealing rubber ring 50 can be tightly embedded and protrude from the groove. This design not only improves the installation stability of the sealing rubber ring 50, but also enhances the contact effect with the photovoltaic module 30.

[0047] The sealing rubber ring 50 is mounted in the mounting groove 20a of the main frame 20. The size and shape of the mounting groove 20a match the sealing rubber ring 50, ensuring that the sealing rubber ring 50 can be tightly embedded and protrude from the groove. Then, the photovoltaic module 30 is placed on the side of the main frame 20 away from the outer glass 10, and the photovoltaic module 30 is tightly attached to the sealing rubber ring 50. The sealing rubber ring 50 protrudes from the groove of the mounting groove 20a and elastically abuts the photovoltaic module 30, forming a sealed barrier.

[0048] The design of the sealing rubber ring 50 and the mounting groove 20a makes it easier to disassemble and replace the photovoltaic module 30. When the photovoltaic module 30 needs to be repaired or replaced, the frame can be disassembled and the air hole 50b can be opened, so that the photovoltaic module 30 can be easily disassembled and installed without the need to disassemble the entire component, greatly improving the maintenance efficiency and reducing the maintenance cost.

[0049] In an embodiment, referring to Figures 1 to 4 , a desiccant 50c is placed in the hollow cavity 50a.

[0050] The desiccant 50c is a moisture-absorbing material placed in the hollow cavity 50a, usually using silica gel, molecular sieve and other high-efficiency moisture-absorbing materials. Its main function is to absorb the moisture in the hollow cavity 50a, maintain a dry environment in the cavity, prevent moisture from corroding and aging the photovoltaic module 30 and the sealing rubber ring 50, and prolong the service life of the component.

[0051] The desiccant 50c continuously absorbs moisture within the hollow cavity 50a, maintaining a dry environment within the cavity, preventing moisture from corroding and aging the photovoltaic module 30 and the sealant ring 50, further extending the service life of the component. The use of desiccant 50c not only improves the reliability and stability of the component, but also reduces the performance degradation and failure risk caused by moisture, ensuring the efficient operation of the photovoltaic component in long-term use.

[0052] In an embodiment, referring to Figures 1 to 4 , the main frame 20 is provided with a plurality of first mounting holes 20b, which are arranged along the extension direction of the main frame 20; the outer frame 40 is provided with a plurality of second mounting holes 40a, which are arranged along the extension direction of the outer frame 40; each first mounting hole 20b is correspondingly arranged with a second mounting hole 40a, and the first mounting hole 20b and the second mounting hole 40a are used for the screw to be sequentially arranged.

[0053] The first mounting hole 20b is a through hole on the main frame 20, used for aligning with the second mounting hole 40a of the outer frame 40, and the connection between the main frame 20 and the outer frame 40 is realized by the screw. The size and position of these mounting holes are accurately designed to ensure the stability and reliability of the connection. The second mounting hole 40a is a through hole on the outer frame 40, used for aligning with the first mounting hole 20b of the main frame 20, and the connection between the outer frame 40 and the main frame 20 is realized by the screw. The size and position of these mounting holes are accurately designed to ensure the stability and reliability of the connection.

[0054] The plurality of first mounting holes 20b on the main frame 20 and the plurality of second mounting holes 40a on the outer frame 40 are correspondingly arranged and sequentially arranged by the screw, realizing the firm connection between the main frame 20 and the outer frame 40. This design not only improves the structural stability of the entire photovoltaic component, but also ensures long-term stable operation under various environmental conditions. The tightening effect of the screw prevents the outer frame 40 from loosening and falling off under the action of wind or other external forces, ensuring the safety and reliability of the photovoltaic component.

[0055] In an embodiment, referring to Figures 1 to 4 , the outer frame 40 includes two horizontal frames 41 and two vertical frames 42, both of which abut against the photovoltaic module 30 and are detachably connected with the main frame 20; and the two horizontal frames 41 and the two vertical frames 42 are arranged around the periphery of the photovoltaic module 30.

[0056] Two lateral frames 41 are installed on the upper and lower parts of the photovoltaic module 30, and tightly abut the top and bottom edges of the photovoltaic module 30. Their main function is to fix the upper and lower ends of the photovoltaic module 30, preventing the photovoltaic module 30 from moving and vibrating in the vertical direction. Two vertical frames 42 are installed on the left and right sides of the photovoltaic module 30, and tightly abut the left and right edges of the photovoltaic module 30. Their main function is to fix the left and right ends of the photovoltaic module 30, preventing the photovoltaic module 30 from moving and vibrating in the horizontal direction.

[0057] The lateral frames 41 and the vertical frames 42 tightly abut the edges of the photovoltaic module 30, ensuring that the photovoltaic module 30 is effectively fixed in all directions. This abutting design not only improves the stability of the photovoltaic module 30, but also prevents damage to the photovoltaic module 30 caused by external forces.

[0058] The lateral frames 41 and the vertical frames 42 are connected to the main frame 20 through a detachable connection method such as screws. This design makes it very convenient to install and remove the frames, facilitating maintenance and replacement of the photovoltaic module 30. The main frame 20 is provided with a plurality of first mounting holes 20b, and the outer frame 40 is provided with a plurality of second mounting holes 40a. These mounting holes are arranged in the extension direction of the frame, and each first mounting hole 20b is correspondingly arranged with a second mounting hole 40a. Screws are sequentially threaded through the first mounting hole 20b and the second mounting hole 40a to fix the outer frame 40 to the main frame 20. This design not only ensures the stability of the connection, but also improves the efficiency of installation and removal.

[0059] The surrounding design of the outer frame 40 and the detachable connection method ensure the stable fixation of the photovoltaic module 30 in all directions. Even in harsh environmental conditions, the photovoltaic module 30 can remain stable and will not shift or vibrate, improving the stability and reliability of the entire photovoltaic component.

[0060] In an embodiment, referring to Figures 1 to 4 , the main frame 20 is also provided with a junction box reserved cavity 20c arranged in the first mounting hole 20b, and the junction box reserved cavity 20c is used to place the wires of the photovoltaic module 30.

[0061] The main frame 20 is also provided with a junction box reserved cavity 20c. The position of the junction box reserved cavity 20c is carefully designed to ensure that it is convenient for the wires of the photovoltaic module 30 to connect and does not affect the overall structure and appearance of the component. The size and shape of the junction box reserved cavity 20c are designed according to the actual size of the wires and the junction box of the photovoltaic module 30, ensuring that the junction box can be smoothly placed and fixed in the reserved cavity. The internal structure of the reserved cavity is usually designed with fixing devices such as clamping grooves or threaded holes for fixing the junction box, preventing it from shifting or loosening during use.

[0062] The main function of the junction box reserved cavity 20c is to place the wires of the photovoltaic module 30. When the photovoltaic module 30 is installed, its wires are led out through the junction box in the reserved cavity, ensuring that the layout of the wires is neat and orderly, and avoiding the wires from being squeezed or damaged during installation.

[0063] The design of the reserved cavity not only provides space for the placement of wires, but also plays a protective role for the wires. By placing the wires and junction box in the reserved cavity, it can effectively prevent the corrosion and damage of the wires by the external environment, prolonging the service life of the wires.

[0064] The design of the junction box reserved cavity 20c makes it more convenient to maintain and inspect the wires. When maintenance or replacement of the wires is needed, only the outer frame 40 needs to be opened, and the junction box and wires can be easily accessed for necessary maintenance and replacement operations without the need for large-scale disassembly of the entire component.

[0065] In an embodiment, referring to Figures 1 to 4 , the junction box reserved cavity 20c is located at the lateral frame 41 on the bottom side of the main frame 20.

[0066] By placing the junction box reserved cavity 20c on the lateral frame 41 on the bottom side, it makes the installation and maintenance of the junction box more convenient. During installation, the wires can be easily accessed from the bottom into the junction box without having to bypass other components, reducing the complexity and time of installation. At the same time, it is easier to access the junction box during maintenance for necessary inspection and repair.

[0067] By placing the junction box reserved cavity 20c on the bottom side, it can reduce the visual impact of the junction box, making the overall appearance of the photovoltaic component more neat and beautiful. This design is particularly suitable for architectural projects with high aesthetic requirements, such as commercial buildings or high-end residences.

[0068] In an embodiment, referring to Figures 1 to 4 , the photovoltaic module 30 is a perovskite photovoltaic module 30.

[0069] The perovskite photovoltaic module 30 has high photoelectric conversion efficiency, with laboratory efficiency exceeding 25% and commercial product efficiency continuously improving, effectively converting solar light into electrical energy. Perovskite materials have excellent optical properties with high light transmittance, allowing for high power generation efficiency while meeting building lighting needs, making them particularly suitable for building-integrated photovoltaic systems. Perovskite photovoltaic modules 30 are lightweight, making installation and maintenance more convenient than traditional silicon-based photovoltaic modules 30, with less impact on building structures. Perovskite photovoltaic modules 30 can effectively generate electricity in low light conditions, maintaining high efficiency even in cloudy or low light environments.

[0070] The high photoelectric conversion efficiency of the perovskite photovoltaic assembly 30 ensures that more electric energy can be generated under the same area, improving the economy and practicability of the photovoltaic assembly.

[0071] Firstly, the outer glass 10 is fixed to one side of the main frame 20 through sealing glue and hot pressing treatment to form an integrated structure, forming the main frame 20 of the assembly.

[0072] Then, the sealing glue ring 50 is installed in the mounting groove 20a of the main frame 20. The size and shape of the mounting groove 20a are matched with the sealing glue ring 50, ensuring that the sealing glue ring 50 can be closely embedded and protrude from the groove.

[0073] Then, the perovskite photovoltaic assembly 30 is placed on the side of the main frame 20 away from the outer glass 10, and the photovoltaic assembly 30 is ensured to be closely attached to the sealing glue ring 50. The sealing glue ring 50 protrudes from the groove of the mounting groove 20a and elastically abuts against the photovoltaic assembly 30, forming a sealing barrier.

[0074] After that, the hollow cavity 50a is inserted through the air hole 50b on the main frame 20 using a vacuum device, and vacuum is extracted to form negative pressure in the hollow cavity 50a. Under the action of negative pressure, the photovoltaic assembly 30 is closely adsorbed on the main frame 20, enhancing the stability of the connection.

[0075] During the vacuum extraction process, the drying agent 50c is placed in the hollow cavity 50a, ensuring that the drying agent 50c is evenly distributed and can effectively absorb the moisture in the hollow cavity 50a.

[0076] Finally, the outer frame 40 is placed on the side of the photovoltaic assembly 30 away from the main frame 20, ensuring that the second mounting hole 40a of the outer frame 40 is aligned with the first mounting hole 20b of the main frame 20. By screwing the first mounting hole 20b and the second mounting hole 40a in turn, the outer frame 40 is fixed on the main frame 20. At the same time, the wires of the photovoltaic assembly 30 are led out through the junction box reserved cavity 20c, ensuring that the wires are arranged neatly and orderly, and the waterproof and dustproof performance of the junction box is ensured through the sealing glue strip or the sealing glue ring 50.
