[0026] Two packaging layers are respectively arranged on both sides of the outermost layer of the power generation device;

[0031] The single crystal silicon wafers and the carbon nanofiber layers are arranged correspondingly to each other;

[0032] The two packaging layers and the carbon nanofiber layer are both designed to have a semi-arc structure.

[0039] Among them, the curvature radius of the semi-arc structure is 500-1000 mm.

[0040] Working principle:

[0041] The working principle of the dual-carbon environmentally friendly monocrystalline silicon high-efficiency distributed photovoltaic power generation device is mainly based on the photovoltaic effect. When sunlight shines on the monocrystalline silicon photovoltaic panel through the transparent tempered glass packaging layer, the monocrystalline silicon wafers in the monocrystalline silicon photovoltaic panel will absorb light energy and convert it into direct current with the help of the photoelectric effect. In this process, each monocrystalline silicon wafer is precisely processed and has excellent photoelectric conversion efficiency. These monocrystalline silicon wafers are connected into a whole through conductive wires, so that the entire photovoltaic panel can generate enough electricity.

[0042] On the bottom of the monocrystalline silicon photovoltaic panel, we specially set up a white EVA board. The white EVA board has a very high reflectivity and can reflect the light that is not absorbed by the monocrystalline silicon back to the photovoltaic panel, thereby increasing the utilization rate of light and improving the power generation efficiency of the entire device;

[0043] The carbon fiber tube sheet is located on the top surface of the monocrystalline silicon photovoltaic panel. It is made of lightweight and high-strength carbon fiber tube material, which not only provides a stable support for the monocrystalline silicon photovoltaic panel, but also reduces the material cost;

[0044] On the top surface of the carbon fiber tube sheet, we further set up a carbon nanofiber sheet, which is composed of multiple carbon nanofiber layers. These carbon nanofibers have extremely high surface area and light absorption capacity, which can further improve the power generation efficiency of the photovoltaic panel. At the same time, the nanoscale size of the carbon nanofiber gives it excellent conductive properties, ensuring the efficient transmission of current in the photovoltaic panel.

[0045] It is worth noting that the monocrystalline silicon wafer and the carbon nanofiber layer are designed to have a one-to-one correspondence structure. This design enables the photovoltaic panel to absorb and convert light energy more efficiently. At the same time, the appropriate spacing between the monocrystalline silicon wafer and the carbon nanofiber layer not only ensures electrical connection, but also avoids heat conduction loss caused by being too close, thereby ensuring the stability of power generation efficiency.

[0046] In addition, the encapsulation layer and carbon nanofiber layer of the device are designed with a semi-arc structure, which not only increases the surface area of ​​the photovoltaic panel and the light receiving area, but also makes the entire device more beautiful and easier to coordinate with various buildings and environments.

[0047] In summary, this dual-carbon environmentally friendly single-crystal silicon high-efficiency distributed photovoltaic power generation device has achieved efficient and stable photoelectric conversion by optimizing the structural design and making full use of the photovoltaic effect, making a positive contribution to the development of the renewable energy field. Its encapsulation layer uses transparent tempered glass material to ensure high light transmittance and excellent impact and wear resistance; the white EVA board improves the utilization rate of light; the carbon fiber tube sheet and carbon nanofiber board further enhance the power generation efficiency and stability. These design features together ensure the high efficiency, environmental protection and long life of the device.

[0048] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
