Photovoltaic power generation has doubled on CCTV!
This time because...
Photovoltaic glass on the Bengbu sports center!
Bengbu Sports Center, Located on the east of Nantao in Bengbu
The planned total land area is 304,019 square meters.
Total construction area of 144,751 square meters
Many technological and environmental elements have been added to the stadium.
The use of solar photovoltaic power generation is one of the highlights
In the sports center, on the circular roof of its large "shell" shape, a piece of black board is installed. These boards are made of a special material called "photovoltaic glass".
A total of 3,444 such photovoltaic power generation glass is installed on the entire roof of the sports center, and their power generation can meet all the lighting and fire-fighting electricity in the venue. This kind of power generation glass is used for roofing, which is both power generation and sunshade, green and environmentally friendly, and can be used as a building curtain wall to integrate with buildings.
(People can also step on the photovoltaic glass)
In China's first copper indium gallium selenide photovoltaic glass production line, the surface of the glass is coated with four kinds of materials: copper indium gallium selenide. Under the combined action of these four substances, the glass can absorb light energy and convert it into electric energy. Instead of traditional crystalline silicon power generation.

Compared with the traditional crystalline silicon photovoltaic solar panels, photovoltaic glass has good low-light performance, low cost and low pollution. The photoelectric conversion efficiency ranks first among various thin-film solar cells, and is recognized as a promising new type in the world. Thin film solar cells.

In the case of the same installed capacity, the advantage of the weak light of the photovoltaic glass can be increased by 10% compared with the conventional crystalline silicon solar panel.
The output of 300MW can be installed on the curtain wall and roof of 2 million square meters, generating 340 million kWh and 100,000 households for one year.
After more than 40 years of research and development, from ultra-thin glass of 1.1 mm to 0.7 mm, from 0.33 mm to 0.12 mm, China has not only broken through this worldwide technical problem, but also became the only one in the world that can produce by float process. 0.12 mm ultra-thin glass country.
Large size, functional, ultra-thin, high transmittance, this is the development direction of glass materials. Today,Chinahas been able to produce dozens of functional glass on a large scale, covering high-rise buildings, new energy, optical components, transportation and other fields. Among them, photovoltaic glass and other products rank first in the world.
(Ultra-thin glass can be rolled up)
The breakthrough and innovation of Chinese technology has reduced the international market price of ultra-thin glass by three times, but researchers have not satisfied the ultra-thin glass of 0.12 mm. Now, researchers are working on ultra-thin glass of 0.10 mm, and the glass that achieves this thinness can be rolled up in the future.
