Chapter 1638

"Mr. Feng, good news, guess what it is?"

It's not good news that Zong Qingxian can call me in the morning with such an excited voice.

Feng Yu thought about the situation of each company and guessed, "is there any good news in Taihua crystal silicon?"

"Mr. Feng, have you guessed that?"

Zong Qingxian still wanted to sell a pass. How could Feng Yu have guessed it out at once.

Feng Yuxin said that in the past, the photovoltaic industry broke out at this time, and the crystalline silicon industry was also very popular.

Although China's crystalline silicon industry was developed earlier in this era, it could not make much money just by selling crystalline silicon. So they also produce some semiconductor components on electronic appliances, which can make more profits.

Although the price of crystalline silicon has gone up once, the billions of dollars of investment have not been earned back yet.

Moreover, the planned production line obviously had some overcapacity. Zong Qingxian and his colleagues had questions. If Feng Yu didn't say that they would make money, they wouldn't let it continue to expand.

It is also the policy initiated by the environmental problems in China since last year. That is to vigorously develop renewable energy and reduce coal, oil and other non renewable energy sources with serious pollution.

At this time, the price of coal has risen to more than 400 yuan / ton. Three years ago, it was only 200 yuan. It is because the country wants to generate electricity and steel, which leads to the rise of coal price.

The same is true for oil. Now the price of oil is much higher than last year, but it's not the fastest time yet, but it's also more than 50% higher than the previous two years.

The rising price of these energy sources has prompted China to vigorously develop renewable energy, including solar energy, water, wind and so on. The most basic is to generate electricity.

So in this period of time, the state has planned several world-class large-scale hydropower stations, which are similar to those of Sanxia.

In some coastal areas, tidal power generation is also studied. In the plateau area, wind power and solar power are mainly studied. There are also some special areas to study geothermal power generation.

Among them, solar power is the most popular, because it can be used not only in civil applications, but also in the field of aerospace.

For example, those satellites and space stations in space are all solar panels. Anyway, in space, the same sun, not affected by the weather.

So solar power is the most important one. It not only has the smallest impact on the environment, but also has the most clean and inexhaustible energy.

Both wind power and hydropower will cause certain damage to the local natural environment, which is higher than that of wind power. Some trees need to be cut down. Hydropower is even more serious. It's a huge project. Many villages and towns have to move and destroy the water, soil and vegetation. Up to now, there's no result.

Solar energy is different. Many years ago, it was used by people. Even when there was no vigorous development, many people used solar water heaters.

Therefore, many countries in the world, especially those with large energy consumption, have made great efforts to study it.

Among them, the United States, Germany, island countries, Spain, Italy, France, the United Arab Emirates, India and China have invested the most energy and achieved the most results.

As for why a big country like Russia can't rank No. 1, that's because the climate problem on their side is really not suitable. They are still more suitable for nuclear power and thermal power.

Since last year, solar power generation has been divided into two directions, one is thin-film solar power generation, and the other is polysilicon solar photovoltaic power generation.

This polysilicon photovoltaic power generation is the new development direction of crystalline silicon industry.

Taihua crystal silicon is the world's largest supplier of silicon minerals. It has not only signed supply agreements with many silicon mines in China, but also acquired some silicon mines by polar bear mining group.

Although it is said that Taihua crystal silicon can't make its own pricing for silicon ore or crystal silicon, any other enterprise that wants to increase or reduce the price must agree with Taihua crystal silicon.

When Taihua crystal silicon really wants to change its price, it can do so only by contacting a few enterprises. However, it is easy to be accused of monopoly. The price increase last time was thanks to the help of the state.

Anyway, Taihua crystal silicon made money, that is, Huaxia made money. It's not just about taxes, but also because it can be used as a weapon for foreign trade. Under normal circumstances, which country does not protect its own industry? Whether he is a state-owned or private enterprise, he can't be taken advantage of by outsiders!

China is also one of the early countries that focus on solar energy research. Although the technology has not reached the top of the world, it can also be called advanced.

Feng Yu has assigned tasks to both Taihua crystalline silicon and Taihua batteries. To study solar power generation and solar cells, the most important thing is to require a high conversion rate.

At this time, the conversion rate of crystalline silicon solar power generation is between 15% and 30%, most of which are 15% to 20%, and the conversion efficiency is very low.And the conversion rate of thin-film solar energy, at this time, the best just reached 15%, the efficiency is lower.

At present, the world record of solar power conversion rate is set by Fraunhofer Solar Energy Research Institute in Germany, which is just over 33%.

This is still theoretical. In practical operation, the efficiency is even lower.

In recent years, in order to study this, Taihua crystalline silicon, Taihua batteries and national laboratories have carried out cooperative development. At present, a new technology has been developed, with a conversion rate of more than 30%.

Although there is still a gap from the first place in the world, it has met Feng Yu's expectation. With this conversion rate, it can be popularized in a large area. To Feng Yu's satisfaction, the construction cost of their solar power station is lower than that of Germany's technology, which is suitable for domestic promotion.

"Laozong, I'm going to the lab tomorrow." Feng Yu said excitedly.

"Mr. Feng, the new year will come the day after tomorrow. Let's go to see it later." Zong Qingxian didn't think so, but was he in such a hurry?

"I can't wait. By the way, this data will be released by the laboratory immediately. Let the world know that we are one of the top countries in the world for solar power generation!"

Sometimes a breakthrough needs to be hidden, but sometimes it needs to be advertised. In this way, they can license their technology and sell their power stations and solar cells to make money.

I have invested so much in R & D, but I have to get some back?

The next step is to continue to make breakthroughs in technology, to make the world leading and become the first in the world!
