Solar energy has become a household name.
After the serious environmental problems caused by fossil energy generation in the 1970s and 1980s, light energy generation became popular.
In the 21st century, China’s photovoltaic power generation is booming, and the photovoltaic panels on the roofs of some regions have become “new landscapes”.
If photovoltaic phalanx is attached to a building and still belongs to the 1.0 version of photovoltaic power generation, the power glass can be said to be an upgraded version.
The glass, which generates electricity, is actually coated with a layer of cadmium telluride, 4 microns thick, on a super-white glass surface.
It is part of a thin-film solar cell, a photovoltaic module that appears as a building material and is part of the building.
Peng Shou painted a future scenarios that occupy the home to the reporter: village residential building, on the sunny side of the wall is invisible “take out” small window, the sun through the power of glass Mosaic of curtain wall, make the bedroom appears clear, warm, dry and burning hot indoor is not due to continued exposure.
Overhead lights, refrigerators, air conditioners and other household appliances can be converted to work through glass.
On a hot summer day, homeowners don’t have to worry about power cuts.
What wonderful changes can a film make of glass?
The film allows the sunlight to enter selectively, making the room “warm and cool in winter”.
Hefei university of technology materials science and engineering college professor luo feng explained, ordinary glass of sunlight “took over”, result in glazing area is larger, the hotter summer house, on the contrary a lot of heat is lost in the winter;
The color and light transmittance of the power glass can be adjusted to block the infrared radiation and reduce the energy consumption.
“No matter how strong or weak, light can generate electricity.”
The glass can absorb more than 95 percent of the sun’s sunlight, and even on cloudy days, it can generate electricity, peng said.
“It’s like a child with an optimistic, sunny disposition.
“Because of this feature, it requires a more casual approach to installation.”
Peng said that traditional photovoltaic panels need to be paved or inclined to match the sun’s Angle, and that the glass can be either flat on the roof or stand as a curtain wall.
Affected by the weather, traditional photovoltaic power generation is unstable, which has been affecting the user experience.
“The same power generation glass is significantly higher than conventional photovoltaic modules throughout the year,” luo said.
When using power glass, a set of energy storage devices can be installed so that during the day, the power supply can be used for the night. Ordinary people can also install two-way electricity meters and sell electricity to the country.
Some netizens have expressed concern that the cadmium telluride used in power glass can cause harm to human body.
He explained that cadmium telluride is a stable compound, and that it is sealed between two pieces of glass, enhancing the use of safety.
The integration of photovoltaic architecture is the future development direction.
The light, stylish and easily integrated generation glass is more suited to this trend, according to luo, and it has long been noted in the United States, Japan and some developed countries and regions in Europe.
In the United States, light, lightweight glass has been made into tiles that are directly applied to roofing.
In the future, there is a bright prospect for the combination of buildings.
This year’s government work report, to “accelerate the construction of manufacturing powerhouse,” “promote integrated circuit, the fifth generation of mobile communications, aircraft engine, new energy vehicles, new material industry development”.
“Policy benefits give us more confidence in the development and application of green development and energy conservation technologies, processes and equipment,” peng said.
His imagination, in the next few years, “glass” to widely used in ordinary People’s Daily live line, cycling, storage battery, electric vehicle charging pile, outdoor carport, you can see it.
Even the phone’s screen could be coated with a conductive film to automatically recharge the solar energy.
