Chapter 94 Perovskite Batteries

After Lin Tianmin went out, Lin Jia came in and handed a stack of the latest employee information to Chen Yuanguang.

There are only a few simple sentences above to introduce the general situation and personality analysis of this group of new employees.

"Is there any response from Li Haide?" Chen Yuanguang asked as he flipped through the materials.

Lin Jia quickly remembered who Li Haide was, "No, the headhunting company told us not to have too high expectations.

Li Haide was a senior executive in JinkoSolar. He joined Guangjia Aerospace, which offered similar treatment but without options, so it was difficult to convince a talent of his level.

The headhunters recommended that we focus on the candidates at the bottom.”

What Lin Jia did not suggest to the headhunting company was that Chen Yuanguang should go and talk to Li Dehai in person.

She thought this was a joke. How could any executive ask Chen Yuanguang to go and talk to her in person? This would make Chen Yuanguang think that she was incompetent and would not be conducive to future work development.

Once Li Dehai joins the company, if he accidentally reveals that he was personally invited by Chen Yuanguang, it will cause any negative impact, which is unknown.

After listening to this, Chen Yuanguang did not comment: "Okay, you follow up on this matter more.

No matter who joins Guangjia Aerospace, we need to set up the results transformation department as soon as possible."

As a huge aerospace project, Guangjia Aerospace will have many research and development results, and the places where these research and development results can play their value are not just in the aerospace field.

Just as a large number of achievements in the aerospace field in the past have borne fruit in the civilian field, computers have even ushered in a new era.

Therefore, for Guangjia Aerospace, the Achievement Transformation Department is particularly important. It is responsible for commercializing the monetizable scientific research results and needs to find suitable partners and sell them at a suitable price.

“The reason why I think Li Dehai is suitable is because our recent achievements suitable for monetization are related to photovoltaics.

And when I looked at his resume, I found that Li Dehai’s current company, JinkoSolar, is engaged in photovoltaics, not to mention that he single-handedly pushed the proportion of JinkoSolar’s ​​patent licensing fees from less than 2% to 15%.

But if he can't do it, we have to start this work, and find someone who can take over temporarily, and train our own talents in the process."

Chen Yuanguang felt that this matter could not be delayed.

When working, Lin Jia was very serious and would not bring emotions into her work. She silently wrote down Chen Yuanguang's words in a notebook, and then said, "I'll go talk to Li Dehai once."

Lin Jia made an appointment with Li Dehai to meet at Starbucks on the first floor of Xinxin Starlight Plaza near JinkoSolar’s ​​headquarters building.

"Hello, Dr. Li." Lin Jia said.

Li Dehai was surprised that Guangjia Aerospace was so persistent in treating him.

Li Dehai holds a Doctor of Law degree from America, majoring in patent law. After returning to China, he joined JinkoSolar and rose through the ranks from JinkoSolar's legal director to vice president in charge of patent licensing.

It can be said that this executive position is a job that was established only after the person was in place.

After receiving the call from the headhunter, he has been learning about Guangjia Aerospace and collected a lot of information. This is a common problem for those who study law, and they hope to obtain as much information as possible.

According to his understanding, Guangjia Aerospace was established not long ago and should not be in a hurry to transform its results. As a result, in order to recruit him, Lin Jia came in person for an interview.

It is rare for an employer to contact the target directly without going through a headhunter. This only highlights the employer's optimism towards the target, which helps him to further raise the price.

This is not generally done. Even if it is urgent, we will let the headhunter come to negotiate.

Li Dehai: "Hello, Ms. Lin, let's get straight to the point. You should understand the saying that a good cook cannot cook without rice.

I am not suitable for Guangjia Aerospace now, which is why I can achieve good results in JinkoSolar.

This is because JinkoSolar has accumulated experience for more than ten years, has thousands of patents, and has a sufficient arsenal for me to use.

Light Armor Aerospace has just been established, and now I am only there to help you build the framework, and this matter does not require me at all."

Lin Jia chuckled and said, “Dr. Li, I checked and found that JinkoSolar’s ​​annual R&D investment is 8 million yuan.

Light Armor Aerospace can pull in 80 billion.

Moreover, we now have technology that needs to be authorized and need to find external manufacturers to cooperate with.

That’s why I came to you in person.”

Li Dehai's expression changed, and he felt that things were starting to get interesting: "Human hibernation technology?

Are you going to sell this technology to the American pharmaceutical giant?

Need someone who knows enough about American patent law to help you avoid pitfalls?
My classmates at America told me that America is in a big fight over clinical trials on human hibernation.

The academic community believes that the government is abusing the technology under the pretext of clinical trials, but most people applaud this, believing that illegal immigrants should stay in hibernation capsules instead of making trouble.

Some ordinary people who have experienced hibernation enjoy it and believe that illegal immigrants are taking up their space.

It seems that human hibernation technology is not only useful in the medical field, its value is indeed huge, and America is likely to force Guangjia Technology to sell this technology.

If this is the case, I can do it as a side job. There is no direct competition between Guangjia Technology and JinkoSolar. "

Li Dehai is clear about the relationship between Light Armor Aerospace and Light Armor Technology.

Lin Jia didn’t know much about American’s situation, so after listening, he just shook his head and said, “No.

It is perovskite. We have developed perovskite battery technology that can be used on a large scale for commercial purposes. It has a complete preparation process and a photoelectric conversion rate that is slightly higher than that of photovoltaics.

And perovskite cells are just the beginning.”

Perovskite is the absolute king in the field of materials, and countless research groups rely on it for their livelihood.

Silicon-based photovoltaic cells are the current mainstream solar cells, while perovskite cells are considered to be the next generation of solar cells.

Now, this young woman with excellent temperament in front of him said something that shocked the entire industry. Li Dehai's heart was filled with waves. If the outside world knew about it, the stock price of the photovoltaic sector would plummet tomorrow.

He didn’t think Lin Jia was joking, it was unnecessary and meaningless: “What is the photoelectric conversion rate, and how does the cost compare to photovoltaics.

What about stability and lifespan?
How is the effect of multi-layer spraying on photovoltaic modules? "Li Dehai was faced with a lot of questions.

Lin Jia smiled and said, “I don’t know about these.

We now need to find manufacturers to cooperate with and promote its large-scale commercial use.

It needs to create value for the Light Armor Aerospace Industry, rather than just stay in the laboratory."

Li Dehai said nothing: "Three days, Ms. Lin, I need three days."

"Dr. Li, welcome to join Guangjia Aerospace. We are currently in great need of talents like you.

After joining Guangjia Aerospace, your work will be brand new and full of challenges." Chen Yuanguang shook hands with the middle-aged man in front of him with his hair combed meticulously.

The handshake lasted for a full ten seconds, and after Li Haide sat down, he said, "Mr. Chen, this is my honor too.

Because I am still a senior executive of JinkoSolar, the resignation procedures there are still being processed.

I have to run back and forth between the two places at the moment. If something happens over there, I may have to go there at any time."

Chen Yuanguang said: "I understand."

Li Dehai continued, “Before I came here, Mr. Lin told me roughly about the current situation of Guangjia Aerospace and also mentioned the new generation of perovskite technology.

I have some doubts that need to be fully understood so that I can start doing this.

At present, my general idea is to use the patent authorization and technology transformation of this technology as a case to promote the construction of the patent authorization system of the entire company. The specific administrative work and system construction are carried out in parallel. What do you think? "

Chen Yuanguang thought to himself that he was indeed a senior executive of a listed company and his management philosophy was mature enough: "I have no objection."

Li Dehai continued: “Regarding your commercially available perovskite cells, do you have any specific data?

I need to fully understand its commercial value.”

Li Dehai's eyes showed enthusiasm. JinkoSolar's main business is photovoltaics. Although he is not a professional, he has worked in JinkoSolar for many years and is very familiar with photovoltaics.

Of course, we also know about perovskites.

Chen Yuanguang rummaged through a pile of materials on his desk for a while, then took out a bound A4 paper and handed it over.

"Here."

Li Dehai took it and said as he looked at it: "The photoelectric conversion rate is slightly higher than photovoltaics.

The stability is not as good as photovoltaics, but a lifespan of five years should not be a problem.”

After looking at the key indicators, he knew that this was a very ordinary data, which could not be compared with the data carefully crafted by most laboratories.

The only advantage is stability, which is better than the best laboratory data currently available.

But its significance lies in large-scale mass production and commercialization.

That's enough.

"Boss, I just have a few questions. How much will it cost if it is prepared on a large scale?

Since 2018, photovoltaic manufacturers led by Longi have been increasing their production capacity every year, and the price of photovoltaic modules has been falling.

It will continue to fall in the future.

The current cost of mainstream photovoltaic manufacturers is 1 yuan/W. As long as the price war does not end in the future, the cost will approach this value. "

Chen Yuanguang thought for a moment and said, "I remember the energy group had a meeting and calculated it before. The theoretical value is 0.5 yuan/W."

Li Dehai was very excited: “That’s great.

The price is low enough and the advantage over photovoltaics is huge.

According to experimental data, five years of stability is sufficient.”

One of the important reasons why perovskite was criticized before was stability.

"I will start looking for partners right away."

After Li Dehai left, Lin Jia, who had been sitting next to him without saying anything, asked in confusion, "Why doesn't he worry about his old employer at all?
As the next generation of solar cells, won’t perovskite revolutionize them?”

Chen Yuanguang explained: "No, because perovskite and photovoltaics are not in conflict with each other, they can be developed in parallel.

The outside world would think that after the emergence of perovskite, the previous crystalline silicon solar cells will be abandoned.

In fact, it will be a layer of perovskite and a layer of polysilicon.

Light has wavelengths, and it is composed of a combination of multiple wavelengths of light. Perovskite and crystalline silicon each have their own strengths in absorbing light.

Therefore, using stacked cells can maximize the use of solar energy.”

Lin Jia understood: “So we have a cooperative relationship with photovoltaic manufacturers.

Li Dehai has worked in the photovoltaic industry for many years and knows best who can quote the price and the styles of each manufacturer.

Chen Yuanguang said: "No matter how perovskite batteries develop, they still need to cooperate with crystalline silicon to give full play to the role of light.

Sometimes it just happens that we want to find the right talent for patent transformation, and Li Dehai happens to appear, and he specializes in photovoltaic patent licensing. "

Li Dehai started working soon after completing the entry procedures. He has many acquaintances in the photovoltaic industry, and both old giants like Longi and Zhonghuan and new players like Huasheng and Yangming have received news.

"Guangjia Aerospace has achieved a breakthrough in perovskite battery technology, which can be commercialized on a large scale. We sincerely invite partners."

The information is very little, and everything that needs to be said is covered.

The company that responded the fastest was Longi. In the cruel field of photovoltaics, slow-moving giants have long been eliminated.

LONGi attaches great importance to this matter. Li Zhenguo personally convened a senior management meeting to discuss Guangjia Aerospace's so-called commercially available perovskite battery technology.

“Currently, HJT is still in the prospecting stage, and Guangjia Aerospace claims that it has perovskite battery technology that can be commercialized on a large scale.

We need to discuss a few key points.

First of all, regarding authenticity, I believe in the credibility of Dr. Chen Yuanguang. There is no need for him to deceive everyone on this matter. Moreover, we all know in the industry that for large-scale commercial use, it is fine if it is allowed, but it is not allowed no matter how it is disguised.

Guangjia Aerospace is not listed, so it does not need to rely on this kind of fraud to raise its stock price.

Furthermore, they poached Li Haide from JinkoSolar. Chen Yuanguang's doctoral supervisor, Mongi Bavendi, is also one of the pioneers in the field of perovskites.

I believe they have achieved large-scale commercial use.

The authenticity does not need to be discussed, so the second point is whether it is a pure perovskite battery, or can it go in the HJT direction.

Is there a conflict in stacking it with crystalline silicon? If it can be stacked, should it be stacked based on the original preparation process, or does it need to redesign the process?

There are many things we need to confirm. Currently, we do not have the three major technical routes of BC, TOPCon and HJT, and the industry has not made it clear which technical route to take.

All leading companies can only move forward in unison and dare not lag behind in any aspect.

As for perovskite, it is possible to combine it with HJT. As a form of HJT, it may also provide new options for the industry.”

HJT has been hyped a lot in recent years. It is called a heterojunction battery. It sounds complicated, but it is actually crystalline silicon and other materials stacked together.

Other materials may be perovskites or something else.

"The other thing is efficiency and stability. Compared with photovoltaics, what are its advantages and disadvantages?

We need to study this clearly.

Finally, regarding the mode of cooperation, neither Chen Yuanguang nor his companies are prepared to fight in the photovoltaic industry.

They will definitely look for partners, including the rumors they have released so far.

So if we want to cooperate, we need to make it clear how we should cooperate.

But this is a topic for later discussion. Let’s first discuss the technical issues.”

After Li Zhenguo finished speaking, he waited for the executives to speak.

　I was writing at night when the power suddenly went out. . .

　　Then I rewrote it. I was really drunk.
