Domestic car manufacturing is weak, what does it have to do with our land tanks?

China National Nuclear Corporation.

Han Zhiqiang was sitting in his office, handling official business.

As the current chairman of China National Nuclear Corporation, he should be relaxed in his office, but at this moment he had a slightly frowned expression.

It was because there was a document in front of him.——

《Lianyungang Offshore Photovoltaic Project Plan

This is an offshore photovoltaic project about 400 to 500 kilometers away from Shanghai.

Instructed by the highest level, the Energy and Power Bureaus of Jiangsu, Zhejiang and Shanghai organized and cooperated in all aspects.

The main responsible party is China National Nuclear Corporation.

The purpose is to build the largest offshore photovoltaic power generation area in China at the Yellow Sea Coast Terminal.

Cooperating with the nuclear power plant of China National Nuclear Corporation Tianwan, using the nuclear power warm drainage area, photovoltaic and nuclear power can be complemented to reduce the impact on the marine ecology.

Conservative estimate.

Once this project is completed, the annual average grid-connected electricity can meet the electricity needs of 400,000 people!

And it is clean energy!!

This project can be said to be very beautiful and green!

In addition to nuclear power plants, the greatest pursuit of mankind is green and clean energy. Not only is there an emission problem, but the main power generation also has to burn coal, which consumes resources.

Before the realization of controlled nuclear fusion, it is certain that every major country is doing what it is to use the environment to generate low-cost green power.

Take nuclear power plants as an example. The early development and utilization of nuclear power plants were not perfect. In addition to causing environmental and ecological pollution, it also caused a lot of energy waste.

As a result, many parallel nuclear power projects came into being, and the”watershed water, wind and solar integrated nuclear base” was born.

In today’s China.

With the prevalence of new energy vehicles, the electricity consumption of the whole nation is also increasing significantly, and the demand for energy is also increasing. Naturally, the country must vigorously expand the scale of power generation, and green energy has the highest priority.

The bay near the nuclear power plant is a tidal flat, and the light level is perfect for the construction and development of large-scale photovoltaic power generation. It can also absorb some light and heat to reduce the impact of warm water discharged from nuclear power plants on the marine ecology, which can be regarded as killing two birds with one stone.

But now there is a problem.

“The original 2 million kilowatts of photovoltaic panels were not delivered. Are you going to stop working on such a large photovoltaic project?……”

Han Zhiqiang’s tone was slightly low.

For CNNC, this was not a big project. The main reason was that there were instructions from the highest level, and he was in charge of it personally, so he would definitely strive to do everything beautifully.

China is a photovoltaic powerhouse, and when it comes to the technology of manufacturing photovoltaic panels, it is undoubtedly in the forefront of the world.

However, the power generation efficiency of photovoltaic panels also varies. Photovoltaic panels sold on the market are generally very cheap, and the power generation efficiency is only around 20%. However, in domestic high-end research institutions, there are advanced crystalline silicon photovoltaic panels that can achieve a power generation efficiency of 32% under ideal conditions.

Some of them were ppts before, and some were really developed, but because the cost has not come down, they have not yet been put into market application.

A batch of advanced photovoltaic kits that Han Zhiqiang ordered from Fudan Institute earlier used crystalline silicon perovskite stacking technology. Because the power generation efficiency exceeded that of single-junction solar cells, a foundry was arranged to prepare to vigorously put this laboratory product into production.

But I didn’t expect

“Leader, this time it is our responsibility. The photovoltaic silver powder originally intended for photovoltaic production was suddenly cut off, and we have difficulty finding a substitute.……”

Over there.

The director of the Fudan Institute smiled bitterly, and did not even dare to make excuses for Yu Han Zhiqiang’s accountability. He only dared to bow and say yes.

“What is going on?”

Han Zhiqiang couldn’t help asking.

To build the Lianyungang offshore photovoltaic project, if ordinary photovoltaic panels were used, they would definitely have as many as they wanted.

But if the photovoltaic panels with the highest power generation efficiency were used, the materials used would not be too simple.

“90% of the materials for manufacturing advanced photovoltaic panels can be supplied domestically, but the low-temperature silver paste and nano-scale photovoltaic silver powder specially used for HJT photovoltaic cells have not yet mastered the process in China. In the previous research and development (cfeb), they were imported from Xiaorizi. Currently, 80% of the world’s nano-scale photovoltaic silver powder is also provided by a group of Xiaorizi.……”

The director of the Fudan Institute immediately said.

Speaking of photovoltaic silver powder, it is actually made by grinding silver into powder. It seems to be a very simple technology, but who would have thought that there are also process barriers.

Ordinary fine silver powder and ultra-fine silver powder are both products above 5um, and can now be domestically produced.

As for ultrafine silver powder (0.1um) and nano-scale silver powder less than 0.1um, the smaller the average particle size, the higher the difficulty of production technology. China is still unable to handle this thing.

From a technological point of view, silver powder is also divided into spherical silver powder, flaky silver powder, and dendritic silver powder.

What is missing in the production of crystalline silicon perovskite laminated solar panels this time is”spherical nano silver powder”. Without this level of silver powder, the silver paste produced cannot meet the conductivity requirements. Once the conductivity drops, the power generation efficiency will also drop. The produced panels will not be much stronger than the photovoltaic panels on the market, and the power generation efficiency parameters will not look good.

Now the National Energy Administration is demanding an increase in the conversion rate of wind and photovoltaic power generation. After all, when photovoltaic and wind power started, it was acceptable to receive subsidies with small benefits. Now that large-scale infrastructure is needed, it must be pursued for benefits.

You can’t just build a spectacle for show!

That’s a waste of money.

Besides, large-scale photovoltaic stations can’t be considered a spectacle!!

At least it’s on the level of the”Three Gorges Hydropower Station”.

“Xiaorizi Group learned that we wanted to purchase a large amount of nano silver powder and proposed to use the nano silver powder process to exchange for crystalline silicon perovskite stacking technology.……”

As soon as these words came out,

Han Zhiqiang also understood what was going on.

“This little place is not big, but it is so beautiful!!”

I laughed in my heart.

The land area and land resources of the little place are not even close to photovoltaic, hydropower and wind power.

They still want their advanced photovoltaic technology? They must want to sell it to their beautiful father at a high price!

As long as China makes an exchange, it will be seen in the United States in a few days. There is a lot of room for photovoltaic power generation there. They have to import a large number of photovoltaic panels from China every year. If they really get the technology, the country will lose foreign exchange.

“That’s it. Since there is no nano silver powder, we will use the next-level process to produce it. Even if the power generation expectation of the entire offshore photovoltaic area is reduced, it can’t be cheap.”

Han Zhiqiang made the decision.

It was originally the first and largest offshore photovoltaic project in China, but it was frustrated before it even started. There is nothing we can do about it.

Fortunately, there are many alternatives in this area in China.

Just after he put down the phone

, another call came in from the Magic City Power Bureau.

“Leader, there is good news. In the past few days, the bureau has received a grid connection application for a large photovoltaic factory project in the port.……”
