Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic glass, in particular to an energy-saving and environment-friendly solar photovoltaic coated glass. Background Art

[0002] Solar photovoltaic coated glass is a special glass integrating multiple functional layers, aiming to improve the photoelectric conversion efficiency of solar energy and achieve the goal of energy conservation and environmental protection.

[0003] Disadvantages of existing solar photovoltaic coated glass:

[0004] 1. Insufficient light transmittance: It leads to a reduction in solar radiation received by the photovoltaic module, thereby reducing the conversion efficiency of solar energy.

[0005] 2. Excessive reflectivity: It increases the reflectivity on the surface of the photovoltaic panel, causing more sunlight to be reflected rather than absorbed and utilized, further reducing the conversion efficiency of solar energy. In addition, excessive reflection may also increase the risk of light pollution.

[0006] 3. Low functional integration degree: It causes the photovoltaic glass to be unable to integrate multiple functions simultaneously, which may limit its application scope in buildings, increase the building cost, and reduce its energy-saving and environmental protection effects.

[0007] 4. Insufficient cleaning ability: It causes impurities such as dust and dirt to accumulate on the surface of the photovoltaic glass, affecting its light transmittance and power generation efficiency. And it may cause problems such as corrosion and damage.

[0008] 5. Insufficient safety: It may cause the photovoltaic glass to be fragile or broken when subjected to external impact, generating sharp fragments, posing a safety hazard to personnel and the environment. In addition, if the photovoltaic glass is installed in an area with dense population or vulnerable to external impact, once it breaks, it may also pose a threat to the surrounding environment and personnel. Content of the Utility Model

[0011] A nano self-cleaning coating is coated on the front side of the second low-iron glass substrate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. High light transmittance and low reflectivity: Due to the adoption of the first low-iron glass substrate and the second low-iron glass substrate, this kind of photovoltaic coated glass has high light transmittance and low reflectivity. The high light transmittance ensures that more solar energy can pass through the glass and be efficiently absorbed and converted into electrical energy by the photovoltaic coating layer, improving the photovoltaic conversion efficiency. While the low reflectivity reduces the energy loss caused by light reflection and also improves the visual comfort.

[0015] 2. Multi-functional integration: The design of the composite functional layer enables this kind of photovoltaic coated glass to integrate multiple functions. The ultraviolet protection layer can effectively block ultraviolet rays and protect indoor items and personnel from ultraviolet damage; the heat reflection coating can reflect the heat energy in sunlight, reduce the heat entering the room, and improve the indoor comfort; the sound insulation layer can reduce the transmission of external noise and improve the indoor quietness; the high-efficiency photovoltaic coating layer realizes the conversion of solar energy into electrical energy and achieves the photovoltaic power generation function; the safety explosion-proof layer improves the safety of the glass.

[0016] 3. Energy conservation and environmental protection: By converting solar energy into electrical energy through the photovoltaic coating layer, this kind of photovoltaic coated glass can directly utilize solar energy for power generation, reducing the dependence on traditional energy sources and having significant energy-saving effects. At the same time, due to its high light transmittance and low reflectivity, it can reduce the indoor lighting demand and further reduce energy consumption. In addition, the nano self-cleaning coating can automatically decompose the dirt in rainwater, keep the glass surface clean, reduce the need for manual cleaning, and further reflects its energy conservation and environmental protection characteristics.

[0017] 4. Improve indoor comfort: The presence of the heat reflection coating and the sound insulation layer enables this kind of photovoltaic coated glass to effectively reduce the transmission of heat and noise, improving the indoor comfort and quietness. In the hot summer, the heat reflection coating can reflect the heat energy in sunlight and reduce the indoor temperature; in a noisy environment, the sound insulation layer can reduce the interference of external noise and provide a more peaceful indoor environment.

[0018] 5. High safety: The setting of the safety explosion-proof layer makes this kind of photovoltaic coated glass have high safety. Even under external impact, the glass is not easily broken or splashed, reducing the safety hazards caused by glass breakage. Description of the Drawings
