Product Description

The night is drooping, and a huge diamond-shaped grid curtain wall composed of LED lights is lit up. The agile colors intertwine in the night sky to form a gorgeous and colorful web of light, lighting up the beautiful future energy hall, creating Vivid and beautiful city night scene. The photovoltaic curtain wall of the future energy hall was debugged with floodlighting.

The core concept of the planning and design of the future energy museum is abstracted from the distinctive themes of historical context, ecological civilization and energy revolution, and combined with the photovoltaic curtain wall design in the upper part and roof part of the building, to create a light and stretchable, transparent and agile "cloud" image. Because the LED lighting control system is a three-color system, a variety of lighting solutions can be combined, and the light color can be changed, which enriches the night scene of the Science and Technology Park and surrounding cities. The lights on weekdays are mainly monochromatic, and you can increase the color changes when you encounter holidays or major festivals.

On November 7, 2018, the Shanghai National Convention and Exhibition Center, the first China International Import Expo intelligent and high-end equipment exhibition area, can be used as a curtain wall for power generation glass. This exhibit called Functional Art Photovoltaic Integrated Building combines artistic and non-toxic and environmentally friendly copper indium gallium selenium (CIGS) power generation functions into one, which is very modern and stylish.

Copper indium gallium selenium (hereinafter referred to as CIGS) -BIPV demonstration buildings were successfully put into use to generate electricity, opening BIPV, a huge new type of distributed energy market. CIGS thin-film photovoltaic modules with core technology and independent production are used as building exterior decorative curtain walls. A total of 2037 CIGS photovoltaic modules were used in the project, with a total installed capacity of 198.61kW. The distributed power generation model of "spontaneous self-use, surplus electricity access to the grid, and efficient use nearby" was adopted, which effectively avoided the problems of large ground power stations and high energy storage equipment costs . It has the characteristics of safety, beauty, durability and high power generation. It is a new type of green building wall material, which realizes a high degree of integration of CIGS photovoltaic technology and building art, and can effectively provide renewable energy for buildings and greatly improve the building quality.

JDSOLAR thermal efficiency building photovoltaic technology. The demonstration building innovatively developed a ventilated photovoltaic wall. The photovoltaic curtain wall and the inner wall form a vertical closed cavity, which not only solves the problem of fire prevention between layers of the building, but also reduces the temperature of photovoltaic modules and improves the efficiency of power generation. Ventilation louvers and cavity heat extraction systems are designed at the bottom and top of the curtain wall, and combined with an air source heat pump, the hot air in the cavity is collected and extracted to provide domestic hot water, which realizes the comprehensive utilization of thermal efficiency.

JDSOLAR photovoltaic curtain wall quick assembly technology. The photovoltaic curtain wall integrated system uses an innovative design of a frame curtain wall system and a dry-hanging construction process. It has a high degree of assembly, fast construction speed, and reliable safety performance.

BIPV is not only an important market and hot spot in the photovoltaic industry's transition from a centralized ground station to a distributed power generation market, but also an important technical means for the construction industry to develop green buildings and near-zero energy buildings. Building energy consumption is up to 45% of the total energy consumption of society. Reducing building energy consumption is an important part of the energy revolution.

The biggest difference between a photovoltaic curtain wall and a traditional curtain wall is the difference in the panel. Except for the power generation characteristics, it has the same architectural characteristics as other curtain walls. The panel of the photovoltaic curtain wall uses photovoltaic power generation components. It is a kind of special power generation glass that is encapsulated with silicon material between two glass panels. It is similar to sandwiching photovoltaic cells between laminated glass. As shown below:

At present, there are mainly two technical routes for photovoltaic curtain wall panel materials: one is a crystalline silicon material curtain wall, and the other is an amorphous silicon material curtain wall. The former photovoltaic module is polycrystalline silicon or single crystal silicon material, which has the advantages of high photoelectric conversion efficiency, small installation size, and mature production materials and technologies. However, the disadvantage is that the curtain wall has poor light transmission and performs poorly under high temperature and low light conditions. The latter has strong low-light power generation capacity, but low conversion efficiency and low power generation per unit area.

In the curtain wall industry, photovoltaic curtain walls with power generation functions are also particularly noticeable. Because in 2010 China's existing urban and rural construction area reached 45 billion square meters, more than 99% of which belonged to high-energy-consumption buildings, so the prospects for energy-saving new construction and reconstruction are very broad.

The early-developed photovoltaic curtain wall is an extension of the light-wall electric roof on the curtain, but the facade of the curtain wall has higher lighting and aesthetic standards than the roof, so higher light transmission requirements are imposed on the original crystalline silicon materials.

Compared with crystalline silicon curtain wall, although the development of amorphous silicon is relatively late, and the photoelectric conversion efficiency is lower than that of crystalline silicon material, the photovoltaic module used in the amorphous silicon curtain wall, the thin film battery itself, has better light transmission and is more resistant to high temperatures. Also works under low light conditions. Compared with the crystalline silicon curtain wall component, which has a single appearance color, the amorphous silicon curtain wall component can better integrate with the building facade without affecting the appearance of the building, and has become a new hot spot in the market.
