What we developed this time is a "power-generating glass". Its scientific name is "cadmium telluride thin-film solar cell". This is not ordinary glass, it is a glass that can generate electricity. At this time, many people don't understand. It is obviously an insulator, so why can it generate electricity?
It is specially used for conductive glass and is a kind of ITO glass. What is ITO.
ITO is an N-type oxide semiconductor. Its film is a semiconductor transparent conductive film. It usually has two properties, transmittance and resistivity. It has very strong conductivity and transparency, and can effectively block substances harmful to the human body. Electronic radiation. The ultraviolet rays and far infrared rays we usually encounter can be blocked by it, which is why it is used in glass.
Since humans began industrialization, the pursuit of natural resources has begun to decline, and the tools used by people are not limited to human and animal power, but have turned to various energy sources.
For example, our natural gas and oil have become our most important energy resources at present, but the frequent use of humans has also caused us to have resource shortages. If these resources are exhausted, what should we do?
Most resources are non-renewable resources, so once developed, humans will eventually face the exhaustion of resources. So in order to face this problem, people began to look for energy that can be recycled, energy-saving and environmentally friendly.
For example, our wind power generation, as a sustainable energy source, converts natural wind into electrical energy, which is also very good in terms of ecological environmental protection. It is a completely clean and harmless renewable energy source.
We can use wind energy, and solar energy can also be used by us. At present, solar energy has been widely used in our country. For example, solar water heaters have been popular for a long time. As long as there is enough sunlight, sunlight can be converted into electrical energy. It is also a harmless and recyclable energy source.
But now there are many aspects of solar power generation, but the power generation is still not as good as other power generation technologies. This problem is difficult to solve. Innovative technology is definitely needed, so some experts suggest developing a glass that can generate electricity.
After all, glass is an indispensable part of the building system. With the development level of modern people, the research on glass has been quite detailed and can be used in many occasions.
For example, our common armed vehicles are equipped with bulletproof glass, and office buildings are equipped with heat-insulating reflective glass. These are the distinctive features of modern glass.
So how to develop this kind of power generation glass? We apply a layer of cadmium telluride coating on the glass, and then combine a layer of glass with this material to another piece. This will turn the originally non-conductive glass directly into a conductor, and it can even absorb sunlight. Therefore, it is converted into electrical energy and stored.
Moreover, this glass can not only generate electricity, but also has strong strength. This glass can be used in ordinary building facilities.
For example, in a building, it is a waste to use ordinary glass as the visiting part. A lot of sunlight can only be refracted and cannot be used. However, using this glass that can generate electricity can completely reduce a lot of electricity consumption in the building, which is very practical.
Then we might as well look at the big picture. If all the exterior wall glass of a city is replaced with this kind of glass that can generate electricity, how much electricity can be collected and stored in a year. It is possible to be completely self-sufficient.
Having said so much, many friends will wonder, since it is so powerful, why don’t we see this glass being widely used in the market now?
In fact, for many years, this glass has only existed in theory, and it is difficult to manufacture it in practice.
But today, the power-generating glass we developed is all the hard work of a Chinese scientist. Without his research and development capabilities, we would certainly not have achieved the results we have today. He is the scientist Pan Jinggong.
This scientist has focused on learning the world's most advanced scientific and technological knowledge since he was a child. He spent his whole life in school. After graduating from school, he entered the United States and began to learn professional knowledge more deeply.
He also achieved many outstanding research results in the United States, which also attracted a lot of attention and obtained more research resources and funds.
Later, he devoted all his energy to the research of cadmium telluride power generation glass and established a research center to specialize in this glass technology.
Hard work pays off, and cadmium telluride power generation glass is no longer a piece of paper. Scientist Pan Jinggong led his team to successfully develop this technology, and also changed the development direction of the world's energy pattern.
Once the power generation glass was successfully developed, it attracted the attention of many high-end companies in the United States, and they all hoped that he could work in their own companies. Some companies even tried to buy out the patent at a sky-high price.
Faced with various temptations, Pan Jinggong did not change his mind at all, and resolutely returned to the embrace of the motherland to benefit the Chinese people with the complete cadmium telluride power generation glass manufacturing technology.
After returning to China, he founded his own technology in Ya'an, Sichuan. Because there is a larger tellurium deposit in China, tellurium is the most important metal for making power-generating glass, so it is very suitable to choose this place.
Metal tellurium is also rare in the world, but the tellurium deposit in Ya'an, Sichuan, my country has a very large reserve and is an independent tellurium deposit in the world. It can be seen that mastering rare resources is crucial to the development of our country.
Our cadmium telluride power-generating glass was developed by Dr. Pan Jingong. The most prominent feature at present is the energy conversion rate.
The energy conversion rate has increased from 10% to 18%, directly reaching the second in the world. If a single piece of cadmium telluride power-generating glass is used in construction, the glass area alone will be 3 times ahead of the United States. It is more than enough to be the glass of a skyscraper.
