What can a piece of glass do other than shelter from wind, rain, light, or artwork? At the two sessions, Peng Shou, deputy to the National People's Congress, general manager of the China Building Materials Kaisheng Technology Group and president of the Handan Glass Industry Design Institute, said that glass that can generate electricity has been born and will emerge in the construction and other industries in the future.
The
Solar energy has become widely known. After experiencing the serious environmental problems brought about by fossil energy generation in the 1970s and 1980s, light energy generation has become popular. In the 21st century, the photovoltaic power generation heats up in China. Photovoltaic panels arranged on the roofs of some regions have once become "new landscapes."

The
If it is said that the PV array is attached to the building and it belongs to the 1.0 version of photovoltaic power generation, then the power generation glass can be said to be an upgraded version of it. Will generate electricityglassIn fact, a 4 micron thick cadmium telluride material is plated on the surface of an ultra-high white glass. It is a type of thin-film solar cell. Photovoltaic modules appear as building materials and become part of the building.
The
Peng Shou painted a picture of a future home for the reporter: In the residential building of the residential area, the small window of the "Shu" can no longer be seen on the side of Xiangyang's side wall. The curtain wall made of sunlight splicing through the power generation glass makes the bedroom look like a bedroom. Bright and warm, the interior is not dry and hot due to continuous exposure. Home appliances such as dome lamps, refrigerators, and air conditioners work as usual through the conversion of light energy from the glass. In summer, homeowners do not have to worry about power outages.
The
What wonderful changes can be made to a glass film?
The
The film allows the sun to enter selectively, making the room “cool in winter and cool in summer”. Luo Paifeng, professor of the School of Materials Science and Engineering at Hefei University of Technology, explained that ordinary glass “completely receives” sunlight, resulting in a larger window area and a hotter house in summer. On the contrary, it will lose a lot of heat in the winter; the color of the power generation glass And light transmittance can be adjusted, can block infrared radiation, reduce energy consumption significantly.
The
"Whether it is strong or weak, there is light to generate electricity." Peng Shou said that the power generation glass can absorb more than 95% of the sun, even if it is cloudy, it can absorb light and generate electricity. “It's like an optimistic and cheerful child. The typical 'glow to the sun is brilliant.'”
The
"Because of this characteristic, it requires more rigorous installation angles." Peng Shou said that traditional photovoltaic panels need to be tiled or slanted to ensure that they match the sun's irradiation angle, and that the power generation glass can be tiled. On the roof, you can also stand and act as a curtain wall.
The
Affected by the weather, traditional photovoltaic power generation is unstable and has always affected the user experience. Luo Paifeng said: “The same generation of power-generating glass generates significantly more power than traditional photovoltaic modules throughout the year. When using power-generation glass, a set of energy storage devices can be installed so that during the day, plenty of electricity can be supplied at night, and ordinary people can also install bidirectional meters. Sell ​​the electricity to the country."
The
Some netizens have expressed concern that the use of cadmium telluride materials for power generation glass will cause harm to the human body? Peng Shou explained that cadmium telluride is a very stable compound and it is sealed between two pieces of glass to enhance the safety of use.
The
Photovoltaic building integration is the future direction of development. Luo Paifeng believes that lightweight, stylish and easy-to-integrate power generation glass is more suitable for this trend, and it has long been noticed by some developed countries and regions in the United States, Japan, and Europe. In the United States, thin and light power generation glass has been made into tiles that are applied directly to the roof. In the future, prospects for power generation glasses combined with buildings are promising.
The
This year’s government work report puts forward the need to “accelerate the building of strong manufacturing countries” and “promote the development of integrated circuits, fifth-generation mobile communications, aircraft engines, new energy vehicles, and new materials industries”. Peng Shou said: “Policy benefits allow us to have more confidence in the development, application and application of green development and energy saving and environmental protection technologies, processes and equipment.” He imagined that in the next few years, “Generating Glass” will be the daily life of ordinary people. Widely used in the car battery riding, electric car charging piles, outdoor carports, can see its presence. Even the mobile phone screen may be coated with a conductive film to achieve automatic solar charging.
