As we all know, power generation in power stations is just the completion of the production process.

You want to close the sale and make a profit.

You have to sell online.

At present, the wireless transmission project is mainly carried out in the mountain city.

So they want to sell the electricity that the satellites transmit back to Earth.

It is inseparable from the State Grid.

"Director Lu, welcome!"

The CEO of the local power grid company greeted him very warmly.

Lu Zhenghe is the head of the Energy Bureau.

Before that, it was difficult for him to see each other.

"Mr. Ge, don't be so polite." Lu Zhenghe said with a kind smile.

"I'm here today just to observe.

Don't be so nervous. ”

Although Lu Zhenghe said this, General Manager Ge, who was present, would not take it seriously.

Such a big guy, how can he just be an observer.

I guess it's for the other party to come to the platform.

Fortunately, he did not offend the other party.

The wireless power transmission project was jointly developed by the ZF of the BS zone and the Rocket Research Institute.

At present, a company in which both parties hold shares has been registered.

It's called Galaxy Power Technology.

The main shareholder is the Rocket Research Institute.

It holds 72% of the shares of Galaxy Power Technology.

BS ZF holds the remaining 20% of the shares.

All employees of Galaxy Power Technology hold the remaining 8% of the shares.

However, employee collective shares only have the right to dividends.

and does not have the right to vote.

"Mr. Ge, let's start as soon as possible."

Yang Yi said with a smile on his face and generously:

"It's all good for us to get this done as soon as possible."

Yang Yi is currently the CEO of Galaxy Power Technology.

Negotiations will be held with the local national grid.

What they are going to talk about today is the issue of wireless power transmission.

The wireless transmission base in the BS area can now be connected to this power network.

However, because the feed-in tariff has not yet been negotiated.

Therefore, the entire network access work is still at a standstill.

"According to the current "Interim Measures for the Management of Photovoltaic Power Station Operation and Maintenance Subsidy Funds", on the basis of the basic electricity price, we will give a subsidy of 0.42 yuan for each kilowatt-hour of photovoltaic grid."

Although Lu Zhenghe was present, Mr. Ge did not dare to deviate from the scope of the management regulations.

According to the current routine operation, Yang Yi was given a very common subsidized price.

After a slight glance, he saw that Lu Zhenghe had no intention of saying anything.

Ge Yihui's little heart has put down a lot.

"Mr. Ge, according to our current western photovoltaic grid price, is our basic electricity price 1.09 yuan or 1.5 yuan?"

Yang Yi didn't dwell too much on the subsidized price.

Rather, it is a problem that the other party avoids the important and trivial.

In fact, there are different standards for the price of western optoelectronics.

The criterion for distinguishing between the different criteria is mainly the degree of local development.

In order to take care of some underdeveloped areas.

The state will subsidize an additional feed-in tariff of 0.41 yuan.

For example, four years ago, the institute invested in the construction of a molten salt tower solar thermal power station in the Gobi Desert in northwest China.

Because of the remote location, the price of on-grid power generation is very high.

It reached 1.5 yuan.

And enjoy the state's subsidies for the photovoltaic industry.

The final online transaction price reached 1.92 yuan.

It's sky-high.

"This"

Ge Yihui glanced at Lu Zhenghe, who was accompanying him with some embarrassment.

"The BS zone is located in a place that is not part of our special poverty subsidy area."

Although Ge Yihui's face was facing Yang Yi.

But it makes people feel that his eyes actually fell on Lu Zhenghe.

"So according to the regulations, I'm afraid we can't give you more subsidies."

Ge Yihui moved out of the rules to talk about things, even if other people had opinions, it was difficult to attack on the spot.

After listening to Ge Yihui's words, Yang Yi showed a bigger smile on his face.

"Mr. Ge may not know much about our power generation."

"Our base in the BS zone is not our power plant."

"It's just a transmission and transit base."

"Our solar farm is in space."

"I don't think there's a more barren place in the world than the empty space."

Ge Yihui, of course, knew that their power station was built in space.

But there is no precedent for this matter after all.

He didn't dare to make his own decisions.

So he could only look at Lu Zhenghe, who was sitting on the side.

And tentatively said:

"Land Bureau, do you think that space belongs to the second-class subsidy standard area?"

The previous power stations were both on land and at sea.

How the region is is very easy to tell.

All you need to do is refer to his geographical division.

But space is especially special.

It does not belong to any country or region, and it is difficult to have a division.

This is also where Ge Yihui is in a dilemma.

There is no precedent for such a thing.

The first to make a decision is to bear great responsibility.

This is especially true for projects that involve a huge amount of money.

According to the data that Ge Yihui learned before.

Galaxy Power now generates nearly 150,000 kilowatt hours of electricity per day.

And that's just their current production.

Five times as many solar panels will be added soon.

That is, the complete production capacity is close to 900,000 kWh.

The annual power generation is more than 320 million kWh.

So this seems to be an inconspicuous price of a few tenths of a kilowatt-hour of electricity.

On top of this base, it will suddenly become a figure of hundreds of millions of yuan.

This is also why, although Ge Yihui's first offer gave a subsidized price for poor areas.

But only one class of criteria was given.

There is no reason for the second type of standard.

"At present, China is vigorously promoting the development of the new energy industry, especially in the photovoltaic power generation industry."

Lu Zhenghe after a long silence.

Finally began to speak his mind:

"The space power generation industry is still a thriving blue ocean for us."

"We are the only ones in the world who are exploring such technologies."

"Whether it's for subsidies for remote areas or support for high-tech power companies."

"We should all give them more incentive on the price of electricity generation."

"Let more new energy enterprises be able to invest in scientific and technological research and development."

Lu Zhenghe said it very clearly.

Especially the last two sentences, they were almost said to Ge Yihui's ears.

Give them more subsidies.

Support should be given in more ways.

"In this case, the basic on-grid electricity price of Galaxy Power can be maintained at 1.5 yuan."

After the big leader spoke, Ge Yihui swallowed two mouthfuls of spit and said:

"At the same time, we enjoy our subsidy for photovoltaic power generation, and the final on-grid power generation price is 1.92 yuan."

Getting this price, Yang Yi was still very happy in his heart.

As a high-tech enterprise, they can actually get a lot of preferential policies in the local area.

For example, the tax exemption policy for the first three years.

In terms of taxation alone, tens of millions of dollars can be saved in a year.

These are the money saved upfront.

There will be no dividends for the time being.

According to the consensus reached by Zhang Xingyang and several bigwigs.

Galaxy Power will make crazy exaggerations in the coming period.

It will be installed at a rate of nearly one million per year.

Increase your own power generation.

In order to achieve this purpose, even Galaxy Power's shareholding will change to a certain extent.

A capital injection is required to issue additional shares.

"Thank you Mr. Ge for your strong support to us."

Yang Yi said with a smile.

"On behalf of all our shareholders, I thank you."

"It's not easy for us to give such conditions." Ge Yihui pretended to be difficult and said.

"I hope you can recruit more employees from our local area."

It's actually a tradition.

The local government has given relatively favorable conditions, so it is natural to stimulate local employment and consumption.

In recent years, there have been a number of cities that have relied on a few large companies to boost employment and consumption.

"That's natural, we are a company with a sense of social morality."

Yang Yi said after smiling.

"Besides, we now have a high proportion of local employees."

The main personnel of Galaxy Power is the staff of the wireless transmission receiving end experimental base.

The vast majority are locals.

Only a small number of researchers and managers come from other places.

"Director Lu, I don't know what else you have to do next?

Do you want me to accompany you? ”

After the negotiation meeting ended, Ge Yihui asked Lu Zhenghe with a little flattery.

Lu Zhenghe looked at the slowly setting sun in the sky: "Next, we have to run the power grid in a few more places." ”

"I won't bother you."

The main purpose of Lu Zhenghe's trip is to give Galaxy a power platform.

And the place of the platform is not just the mountain city power grid.

Galaxy Power will not be limited to just one mountain town.

"Lu Bureau, our next stop is to go to Donghai City."

After leaving the headquarters of Shancheng Power Grid, Yang Yi found Lu Zhenghe and said.

"The situation in Donghai City may be more complicated."

As a modern metropolis.

Tokai City has a permanent population of tens of millions.

Every day, urban residents alone consume hundreds of millions of kilowatt-hours of electricity.

What's more, Tokai City also has an extremely large industry.

A larger amount of electricity needs to be consumed.

Because of this, the power supply in Tokai City has been insufficient for many years.

Especially in the summer.

During peak electricity consumption periods, various districts and streets have to carry out time-sharing power supply.

It has brought great inconvenience to the production of enterprises and the lives of residents.

Even every year, Tokai City will add a lot of new power station capacity.

And some surrounding cities will share a part of the electricity.

But it still can't keep up with the growth rate of his electricity consumption.

The next step for Galaxy Power is to establish several wireless transmission receivers in Donghai City.

It is used for power regulation.

The new power generation satellites launched next year will also add their own strength to the power supply of Donghai City.

Rocket Research Institute, Materials Experiment Center.

Zhang Xingyang is trying to prepare the fourth generation of semiconductors.

The third generation of semiconductors currently used in power satellites.

Although already very advanced.

But on closer inspection, he also has a lot of problems.

When gallium nitride works, the energy consumption is large and the calorific value is large.

These problems are particularly unbearable on power generation satellites.

In particular, the problem of heat generation even forced the Satellite Research Institute to design a large-scale cooling system.

Zhang Xingyang is researching how to industrially prepare large-size fourth-generation semiconductors.

What is the fourth generation of semiconductors.

This question was answered in the twentieth century.

Gallium oxide.

It has more powerful performance than gallium nitride.

In particular, there are aspects such as band gap, critical breakdown field strength, and transparent conductivity.

are far more than gallium nitride.

And under the same conditions, the energy consumption of the oxidant is one-third of that of gallium nitride.

"The one hundred and twenty-second experiment, failed again."

Su Xiao reported to Zhang Xingyang with a little discouragement.

In the course of these hundreds of experiments.

They prepared more than 200 pieces of gallium oxide.

However, none of them met the requirements of their hearts.

"Is it still a matter of size?"

Zhang Xing raised his head and asked.

"This time it was slightly better than the previous ones, and the 1.5-inch wafer was prepared."

Su Xiao took a bottle of water from the table, took a few sips and said.

"It's 0.1 inch bigger than before, it's worth encouraging, I'll give you a chicken leg tonight."

Zhang Xingyang said half-jokingly.

"Forget it, we'll have to do the one hundred and twenty-third experiment in the evening."

After Su Xiao finished speaking, he touched his stomach: "And I've been losing weight recently." ”

"Let's not talk about this, is there a problem with our preparation method?"

"Should we use the guide method?"

The current production methods of gallium oxide mainly include the lifting method, the floating area method, the guided mode method and so on.

Different methods have their own characteristics.

However, none of them have been able to produce large-scale prototypes.

"We can only use the guided mode method at the moment."

Zhang Xingyang raised his head at this time and said:

"The iridium crucible is used for the lifting method, which is too expensive and easy to contaminate."

The lifting method is actually easier to produce large-sized protocrystals.

Similar operations have been done in labs before.

A large piece of gallium oxide elemental protocrystals was successfully prepared.

But this method cannot be mass-produced.

The price of the iridium crucible doomed him to be confined to the laboratory.

Play with it as a toy.

"The requirements of the optical system of the light float zone method can be called perverted, not to mention us, no scientific research unit or enterprise in the world can produce an optical system that can easily melt raw rods and single crystal seed crystals."

Zhang Xingyang said helplessly: "For us, there is really only the guide model method that can be used. ”

The guided mode method is compared with the first two methods.

There is no need for expensive crucibles, as well as complex optical systems.

However, for process operation, there are extremely high requirements.

But it is also the one with the greatest potential for industrial production.

"But the guide mode method is really difficult, and if there is a slight deviation, the crystals that were originally grown in a directional direction will grow crooked."

Su Xiao said with some embarrassment.

In the mold guide method, the melt and seed crystals are placed in a mold with a thin film inside.

By controlling the temperature gradient, the growth of the wafer is controlled.

It's easier to say.

But because there are a lot of factors involved.

In order to achieve industrial production, it is necessary to have a frighteningly detailed production regulations.

After listening to this, Zhang Xingyang did not answer, but continued to look at his computer.

On the computer is a new type of gallium oxide manufacturing process.

Gallium oxide is produced by metal-organic meteorological deposition.

The method is not complicated.

It is similar to the previous preparation of carbon-carbon composites.

It's just that the substrate becomes trimethylgallium, and the gas becomes high-purity oxygen.

This method is simpler and cheaper to produce. (End of chapter)
