[0024] Building photovoltaic integration is a technology that integrates or combines photovoltaic products into buildings. It is an important technology for achieving carbon emission reduction throughout the life cycle of buildings. In recent years, the power generation efficiency of photovoltaic modules has been significantly improved. The photoelectric conversion efficiency of commercial crystalline silicon photovoltaic modules can exceed 20.0%, and the price of photovoltaic products has dropped significantly. However, the application of building photovoltaic integration technology is still limited to a few exemplary green buildings and has not yet been promoted on a large scale. The important reason is that in building photovoltaic integration, buildings will affect the power generation efficiency of photovoltaic modules. Specifically, the available area of ​​the building roof is limited, and the number of photovoltaic modules that can be accommodated is limited; although the facade can accommodate more photovoltaic modules, the facade is easily blocked, causing the loss of power generation efficiency of the photovoltaic modules. Therefore, the utility model is proposed to solve the problem of power generation efficiency loss when photovoltaic modules are set on the facade.

[0025] The utility model provides a building surface structure.

[0026] See also Figure 1In one embodiment of the utility model, the building skin structure includes a photovoltaic assembly 11 installed on a base wall 1. The photovoltaic assembly 11 is a double-sided power generation structure. The photovoltaic assembly 11 includes a photovoltaic cell, and a first light-transmitting body and a second light-transmitting body arranged opposite to each other. The photovoltaic cell is located between the first light-transmitting body and the second light-transmitting body; the photovoltaic cell is used to convert solar radiation passing through the first light-transmitting body and / or the second light-transmitting body into electrical energy; the angle between the surface of the base wall 1 and the first light-transmitting body and / or the second light-transmitting body is greater than 0 degrees. Such a configuration, on the one hand, increases the number of absorption surfaces of the photovoltaic module 11 for absorbing solar radiation, which can improve the power generation efficiency of the photovoltaic module 11; on the other hand, since the photovoltaic module 11 installed on the base wall 1 is easily blocked, which is an important reason for the loss of power generation efficiency, the angle between the surface of the base wall 1 and the first light-transmitting body and / or the second light-transmitting body is greater than 0 degrees, that is, the first light-transmitting body and / or the second light-transmitting body are not parallel to the surface of the base wall 1, which can reduce the impact of the building on the first light-transmitting body and / or the second light-transmitting body, increase the contact area between the photovoltaic cell and the solar radiation, and thus improve the utilization efficiency of solar energy. Among them, the first light-transmitting body and the second light-transmitting body can be glass plates, or panels made of other light-transmitting materials. Therefore, the technical solution of the utility model can improve the power generation efficiency of the photovoltaic module 11. In addition, the photovoltaic module 11 also has a certain sunshade effect, thereby playing a heat insulation effect on the interior of the building, which can reduce the comprehensive energy consumption of the building.

[0027] Specifically, the building skin structure further includes a fixing member 4, and the photovoltaic module 11 is connected to the base wall 1 through the fixing member 4.

The wall connector 8 can be provided in a pre-embedded or post-embedded manner.

[0028] In some embodiments, the building surface structure also includes a green plant component, which is arranged on the outside of the base wall 1. By rationally configuring the photovoltaic components 11 and the green plant components, the building surface structure proposed by the utility model can achieve coordinated optimization of indoor and outdoor thermal environment regulation, renewable energy utilization, and carbon sequestration and emission reduction benefits throughout the life cycle of the building. Specifically, the photovoltaic components 11 convert solar energy into electrical energy, increase clean energy in the city, and help reduce carbon dioxide emissions caused by fossil fuel power generation; the shading effect of the photovoltaic components 11 can also improve the thermal insulation performance of the building and reduce the comprehensive energy consumption of the building. On the one hand, the green plant component can play a role in carbon sequestration and emission reduction; on the other hand, the transpiration of the plant leaves in the green plant component and the evaporation of water in the growth matrix can achieve air cooling and humidification, improve the microclimate, alleviate the urban heat island effect, further reduce the comprehensive energy consumption of the building, and reduce the negative impact of air conditioning heat exhaust on the environment.

[0029] Specifically, the green plant assembly includes a plant module 12, which is connected to the base wall 1; the plant module 12 includes plants and planting holes, and the planting holes are located on the side of the plant module 12 facing away from the base wall 1; some plants pass through the planting holes to form a plant layer 9 on the side of the plant module 12 facing away from the base wall 1. Among them, the plant module 12 is provided with a plant growth matrix, and the plant module 12 has the characteristics of being waterproof, wear-resistant, anti-shedding, modular, and simple to assemble.

[0030] Furthermore, the base wall 1 also includes a support frame, which is connected to the base wall 1 through a wall connector 8; the support frame is used to support the photovoltaic module 11 and the green plant module. The plant module 12 is connected to the support frame through a mesh member 5. By setting the support frame and the mesh member 5, it is convenient to install and modularize the green plant component. The mesh member 5 can be made of galvanized material to improve the corrosion resistance of the mesh member 5. Among them, the support frame includes a horizontal support member 2 and a vertical support member 3, and the opposite sides of the horizontal support member 2 are respectively connected to the wall connector 8 and the vertical support member 3; or, the opposite sides of the vertical support member 3 are respectively connected to the wall connector 8 and the horizontal support member 2. And, the plant module 12 is provided with a hanging member 6 on one side close to the mesh member 5, and the hanging member 6 is used to hang the plant module 12 on the mesh member 5, and the plant module 12 is installed by hanging, which further improves the convenience of installation. In addition, the photovoltaic module 11 can also be connected to the support frame through a fixing member 4 to improve the installation stability of the photovoltaic module 11. It should be noted that the number, position, spacing, specifications and embedding method of the wall connectors 8 can be determined according to the arrangement of the green plant components and the photovoltaic components 11.

[0031] In some embodiments, the plant module 12 is provided with a water inlet and a drain at both ends in the vertical direction, and the water inlet is located above the drain; the side of the plant module 12 close to the base wall 1 forms a storage space with the base wall 1; the plant module 12 also includes a drip pipe 7, and the storage space is used to accommodate the drip pipe 7, and the drip pipe 7 is arranged corresponding to the water inlet of the plant module 12.

In addition, the drip pipe 7 is accommodated in the storage space, and the storage space is formed by the side of the plant module 12 close to the base wall 1 and the base wall 1, which is equivalent to the storage space being blocked by the plant module 12; such a setting plays a role in making the drip pipe 7 invisible, thereby improving the aesthetics of the building skin structure. In one embodiment, the plant module 12 may be configured to be an inverted trapezoidal shape with a larger upper end and a smaller lower end, thereby forming an accommodating space in a simple manner.
