[0016] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0017] Example 1:

[0018] This embodiment provides a modular photovoltaic curtain wall, including: Fixed frame 1, fixed frame 1 is rectangular; Photovoltaic module 2 is detachably mounted on fixed frame 1 and is positioned on the light-facing side; Backsheet assembly 3 is movably mounted on fixed frame 1 and located behind photovoltaic module 2; The photovoltaic module 2 includes spherical silicon photovoltaic units arranged in a grid and a wire component 21. The wire component 21 is electrically connected to the spherical silicon photovoltaic units and is connected to an external energy storage device.

[0019] As can be seen from this embodiment, a modular photovoltaic curtain wall includes a fixed frame 1, photovoltaic modules 2, and a back panel assembly 3; The photovoltaic module 2 is detachably connected to the fixing frame 1, which facilitates operation during installation, maintenance or replacement; The photovoltaic module 2 adopts spherical silicon crystal photovoltaic units. The spherical silicon crystal photovoltaic units are arranged in a grid on the fixed frame 1 through the wire component 21, which can effectively improve the absorption rate and conversion efficiency of light energy. Compared with the traditional planar silicon crystal structure, the spherical silicon crystal structure has a wider receiving angle and a higher light energy conversion rate, and can collect sunlight more effectively. The conductor component 21 connects to an external energy storage device, enabling the electrical energy to be stored in real time and used when needed. This design allows the modular photovoltaic curtain wall to not only generate electricity but also provide a continuous power supply for the building, enhancing energy efficiency.

[0020] The movable setting of the back panel assembly 3 provides flexibility, allowing for adjustments to indoor lighting conditions according to actual needs, thereby improving indoor lighting performance.

[0021] Furthermore, the spherical silicon photovoltaic unit, together with the wire component 21, forms a grid-like photovoltaic module 2, which helps to improve light transmission performance.

[0022] Furthermore, the fixed frame 1 adopts a modular design, which allows for rapid assembly in the installation room, reducing installation costs and time. Furthermore, the detachable design of photovoltaic module 2 enhances the ease of system maintenance.

[0023] Example 2:

[0024] This embodiment provides a modular photovoltaic curtain wall, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0025] The conductor assembly includes: The movable frame 211 is rectangular and is detachably connected to the fixed frame 1. The power transmission line assembly 212 is mounted on the movable frame 211 and forms a grid structure. The power transmission line assembly 212 is electrically connected to the spherical silicon photovoltaic unit.

[0026] As can be seen from this embodiment, the conductor assembly includes a movable frame 211 and a power transmission line assembly 212; The movable frame 211 is detachably connected to the fixed frame 1, providing flexibility and convenience. This facilitates the installation, disassembly, and maintenance of the conductor assembly. By connecting the transmission line assembly 212 to the movable frame 211, an independent photovoltaic module 2 is formed, making the overall structure more modular. This allows for the replacement or adjustment of the corresponding modules during later maintenance and expansion, without the need for large-scale disassembly, thus saving time and maintenance costs.

[0027] The power transmission line group 212 is arranged on the movable frame 211 and forms a grid structure, which can optimize the stability and transmission efficiency of electrical connection. The grid structure helps to distribute current evenly, reduce losses in the process of power transmission, improve the overall power generation efficiency of photovoltaic module 2, and reduce the blocking of light, thereby improving light transmittance. At the same time, the grid design helps to improve heat dissipation.

[0028] It enables efficient power transmission, flexible system installation and maintenance, and improves the system's heat dissipation performance and scalability, providing a strong guarantee for the high efficiency and long-term stable operation of modular photovoltaic curtain walls.

[0029] Example 3:

[0030] This embodiment provides a modular photovoltaic curtain wall, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0031] Transmission line assembly 212 includes: Fixed line 2121, multiple fixed lines 2121 are arranged horizontally in parallel; Conductive wires 2122 are arranged in multiple sets in parallel longitudinal direction and are intertwined and connected to fixed wires 2121. Among them, the spherical silicon photovoltaic unit is set on the conductive line 2122 and is located between the fixed lines 2121.

[0032] As can be seen from this embodiment, the power transmission line assembly 212 includes a fixed wire 2121 and a conductive wire 2122; The conductive wires 2122 are arranged in parallel longitudinal direction and intertwined with the fixed wires 2121 to form an effective power transmission channel and optimize the current distribution of the power transmission system. Because the conductive wires 2122 are intertwined with the fixed wires 2121, the stability of the line group can be improved, power loss can be reduced, and the overall power transmission efficiency can be enhanced. The spherical silicon photovoltaic units are spaced on the conductive wires 2122 and are located between adjacent fixed wires 2121.

[0033] Multiple fixed lines 2121 are horizontally connected to the movable frame 211 as a support structure. The fixed lines 2121 do not directly participate in the power transmission work, but they provide stable support for the conductive lines 2122 and the spherical silicon photovoltaic units, thereby enhancing the structural stability of the entire power transmission line group 212. The setting of fixed lines 2121 enables the system to maintain high durability and reliability when affected by external environmental factors (such as wind, temperature changes, etc.).

[0034] By combining the photovoltaic unit with the transmission line group 212, the dual functions of power transmission and solar energy conversion are achieved. At the same time, the fixed line 2121 provides structural support and stability in the system, which can improve the system efficiency, reliability and adaptability.

This sliding design enables the back panel assembly 3 to flexibly adjust indoor lighting, avoiding the situation where the traditional photovoltaic module 2 covers and affects lighting.

[0039] The reflective glass plate 32 is fixed to the fixed frame 1, and the reflective surface of the reflective glass plate 32 always faces the photovoltaic module 2. The reflective surface of the reflective glass plate 32 (the reflective glass plate 32 is purchased and its light transmittance is 50-70%) faces the spherical silicon photovoltaic unit, which can guide the reflected light to the side surface of the photovoltaic unit that does not directly face the light, thereby increasing the amount of light received by the photovoltaic unit. Through reflection, the reflective glass plate 32 effectively improves the light energy conversion efficiency of the photovoltaic unit, maximizes the utilization of sunlight resources, and enhances the power generation efficiency of the photovoltaic system. Furthermore, during use, the position of the light-shielding plate 31 can be changed so that light can pass through the reflective glass plate 32 and enter the room.

[0053] Furthermore, the arrangement of the conductive wire 2122 is guided by the pin hole, which can effectively prevent the conductive wire 2122 from interfering with other components or occupying extra space, making the whole system more compact, reducing unnecessary space waste, and improving the overall design level of the system. Furthermore, electrical connectors 7 are provided at both ends of the conductive wire 2122, and the electrical connectors 7 are connected to the second pin hole 52.
