Good luck! This village is full of billionaires

4-15.

Rainbow University.

School of Modern Engineering and Applied Science, Optoelectronic Experimental Teaching Center.

In front of an office.

Sophomore Li Ya knocked on the door respectfully.。

“Please come in! ”

A strong voice came.

Li Ya opened the door with some restraint and came to a professor who was over 50 years old.

He said politely: “Professor Chen, I am a college student majoring in optoelectronic information science and engineering. Second student Li Ya.

I recently wrote a paper, both in Chinese and English versions.

Could you please give me some advice? ”

Hearing this,

Chen Donghe was a little surprised.

Generally speaking, freshman students engage in grade points, sophomore students engage in competitions, and junior students engage in papers.

Students at Rainbow University only have first-year undergraduate students, sophomore undergraduate students, and first-year graduate students. Students, second-year graduate students, first-year PhD students, second-year PhD students.

It is common for first-year graduate students and first-year PhD students to come to him for guidance on their papers.

But it is extremely rare for sophomores to come to him.。

“OK, teacher, let’s take a look. ”

Chen Donghe smiled and nodded.

He put the USB flash drive handed over to the computer USB interface and read the paper.。

“Xiao Li, what field did you write the paper on? Li Ya said truthfully: ”

Professor Chen, I am writing a thesis in the field of photovoltaics. ” ”

Hearing this, Chen Donghe nodded.

The subject field he was engaged in was optoelectronics.

The students came to him for advice, so they were asking the right person.

After reading the paper,

the title appeared on the screen, titled “High Efficiency Full Calcium Titanium laminated solar cells》。

“All-perovskite stacked battery? ”

Chen Donghe’s eyes lit up and he became interested.

Solar photovoltaic power generation has always been the focus of research in the industry.

Existing crystalline silicon solar cells have been used on a large scale, but their photoelectric conversion efficiency is approaching the industrialization limit efficiency. To put it

simply It is said that the cost of photovoltaic power generation is closely related to the battery efficiency.

Every time the battery efficiency increases by 1 absolute value,

the cost of photovoltaic power generation can be reduced by 7.

Therefore, the photovoltaic field is actively developing new photovoltaic technologies with higher efficiency, hoping to break through the traditional The ultimate efficiency of crystalline silicon cells further reduces the cost of photovoltaic power generation. The

all-perovskite tandem solar cell is a new photovoltaic technology in the international cutting-edge scientific field.

Chen Donghe took a deep breath and patiently browsed the paper.

In the paper Wrote:

Building a stacked battery is the most effective way to significantly improve battery efficiency. The

theoretical efficiency of a double-junction stacked battery can reach 45, which is much higher than the S-limit efficiency of a single-junction battery of 33.

Traditional III-V semiconductors Although tandem batteries have achieved high efficiency, the preparation process is complex and expensive.

Perovskite/perovskite tandem batteries constructed by connecting wide/narrow bandgap perovskite sub-cells in series can have both high efficiency and low cost. outstanding advantages.

Li Ya proposed an atomic layer deposition technology to prepare a new tunnel junction structure with a thin and dense semiconductor layer and an ultra-thin metal cluster layer, achieving a significant simplification of the preparation process of all-perovskite stacked cells and devices. Significant improvement in performance.

Then, he controlled the crystal growth process of narrow-bandgap perovskite through the oxidation of stannous ions Sn2+ inside and on the surface of the perovskite grains.

This effectively reduced the defect state density of the film and increased the number of carriers. The diffusion length overcomes the core bottleneck that limits the efficiency of all-perovskite stacked cells.

He has successively achieved small-area stacked cells with conversion efficiencies of 24.8 and 25.6, and developed a large-area all-perovskite stacked cell with a conversion efficiency of 24.2!

Chen Donghe looked at the paper and became more and more frightened.

The 24.2 all-perovskite stacked battery is simply genius research.

Such high efficiency has already broken the world record in the field of all-perovskite stacked batteries!

If we continue to work hard Keep researching.

All-perovskite stacked cells are expected to surpass crystalline silicon cells and create a milestone in the field of photovoltaic power generation!

The paper contains dense experimental data in detail, which is well-founded and convincing.

Read the full paper.

Chen Donghe’s heart was filled with turmoil.

Is this really a paper that a sophomore (cdah) student could write?

He was surprised that a doctoral student could write such a paper.

Not to mention that Li Ya is only 19 years old this year and is still a graduate student. A sophomore.

Didn’t he copy it from a foreign website?

Thinking of this,

Chen Donghe logged into the paper plagiarism check website and uploaded the entire paper. The

repetition rate was 0.5!

Those who passed the test could no longer pass the test. .

Chen Donghe raised his head, looked at Li Ya with sharp eyes, and asked: “Did you really write this paper?”

“Professor Chen, I really wrote the paper!

Li Ya, who was a little reserved at first, now looked determined. Li Ya said: ”

Professor, the school’s School of Modern Engineering and Applied Science has a 65,000-square-meter high-standard scientific research building with various high-end instruments, which is very suitable for experiments. .

Before I knew it, spending time in the laboratory had become a daily routine for me.

When functional layers are combined into solar cells, sunlight not only transforms into jumping numbers on the instrument through the band gap, but also reflects the colorful light in my heart.

The competition for all-perovskite stacked cells is extremely fierce.

Domestic research is not as good as global researchers in related fields.

I hope to do my part to surpass them in the new photovoltaic field!”

“very good! ”

Chen Donghe looked at Li Ya’s clear eyes and nodded with satisfaction.

A thousand miles cannot be accomplished in a day.

Li Ya is a sophomore, but he can endure boredom and is willing to spend more time studying.

He is undoubtedly a scientific researcher. What a promising idea!

Chen Donghe said happily: “Xiao Li, your paper is shocking, I have nothi

ng to advise you.

The only flaws that can be found are the layout of the paper and the wording of details.

Leave the paper with me for now and I’ll revise it for you.。”

“Thank you Professor Chen! ”

Li Ya quickly thanked you.

Chen Donghe continued: “But you can’t publish this paper!”

“ah? why is that? ”

Li Ya asked doubtfully.

Chen Donghe said bluntly: “In this paper, your experimental result is to develop a large-area all-perovskite stacked battery with an efficiency of 24.2.

If you want your paper to be published in top journals, you must have an authoritative third-party testing agency conduct professional testing on the all-perovskite stacked battery you have developed.

Authoritative institutions recognized in the photovoltaic field include Xia Guo National Key Laboratory of Photovoltaics, the U.S. National Renewable Energy Laboratory, Neon Industrial Technology Comprehensive Research Institute, Neon Electrical Safety and Environmental Technology Laboratory, and German Fraunhofer Solar Energy Systems. 8 third-party testing institutions including the Research Institute。”

“ah? So troublesome? ”

Li Ya scratched his head, a little depressed.

Chen Donghe said kindly: “I have some connections in the photovoltaic field. I can help you contact the Xiaguo State Key Laboratory of Photovoltaics for the most professional testing.。”

“Thank you Professor! “(To read Baoshuang novels, go to Feilu Novel Network!)

Li Ya thanked him from the bottom of his heart.

If he had asked him to go to these world’s top testing institutions in person, they would have ignored him.

Fortunately, Professor Chen helped!

Chen Donghe Asked: “Xiao Li, have you decided which journal to submit to?”

“Nope!”[]

Li Ya said truthfully: “I just finished my thesis, so I came to you for advice. I haven’t decided which company to apply to yet.”

Chen Donghe was in a good mood at the moment.

He patiently explained: “The three top international academic journals are divided into “nature”, “science” and “ce11″. As long as you can���Publishing a paper in a home journal is more useful than publishing more papers in ordinary journals. ”

Hearing this, Li Ya nodded.

He has long been familiar with the three top academic journals.。

《nature”, natural science journal, impact factor 41.577.

Nature is the world’s oldest international scientific journal, founded in 1869. It consistently reports and reviews the most important breakthroughs in science and technology around the world.

Journals cover life sciences, natural sciences, clinical medicine, physical chemistry and other fields。

《science”, scientific journal, impact factor 41.058.

Scientific Journal is an academic journal published by the American Association for the Advancement of Science and is one of the most authoritative academic journals in the world.

It mainly publishes the latest scientific research results, covering various disciplines。

《ce11″, Cell Journal, impact factor 31.398.

It is the best journal in the field of biological sciences and mainly publishes the latest research findings in the field of life sciences.

Li Ya knows very well that if his paper can be published in these three top academic journals, it will be of great benefit to him in terms of postgraduate entrance examinations, employment, academic research, etc. in the future.

Chen Donghe suggested: “Since you haven’t decided which one to invest in, then choose the journal “Nature” with the highest impact factor.。”

“Thank you Professor, I listen to you. ”

Li Ya thanked him again。

……

Chen Donghe looked at the background of Li Ya’s departure with some emotion.

The waves behind the Yangtze River push the waves ahead.

Each generation becomes stronger than the previous generation.

The current sophomores are truly amazing!

Before he could finish his emotion.

There was another knock on the office door.

Dozens of students came to him。

“Professor Chen, my thesis is called “Elastic Ice Single Crystal Micro-Nano Optical Fiber”, please give me some advice!”

“Professor Chen, my paper is called “Nonlinear Regulation of PT Symmetric and Non-Hermitian Topological States”. I hope you can give me some advice.。”

“Professor Chen, my thesis is called “Desktop Free Electron Laser Driven by Laser Coke Field Acceleration”. I would like to ask you to give me some advice.。”

“Professor Chen, please give me some advice! The name of my thesis is “Three-dimensional heterogeneous integrated MoS2-TFT high-resolution Micro-LED display technology”》。”

“Professor Chen, please give me some advice! My thesis is “Efficient Broadband Achromatic Metalenses for Near-Infrared Bioimaging Window”》。”

“Professor Chen, I also have a paper here that I would like you to point out. The paper is called “The discovery of ghost hyperbolic polaritons in birefringent crystals.”》。”

“Professor, I……”

……

I heard numerous requests from students for guidance on their papers.

Chen Donghe twitched the corner of his mouth and was speechless.

On weekdays, when students ask him for advice, he is naturally very pleased.

But at the same time, so many people came to give advice.

This is a bit exaggerated!

In addition, he is not qualified to give advice on all papers.

These students’ papers have such lofty titles, so he doesn’t understand them, okay?

Guidance? !

Give me some pointers!

You sophomores are all so good at academics.

I’d rather you give me some pointers.……

……

at the same time.

Tutors and professors from various colleges of Rainbow University, like Professor Chen Donghe, have received requests for thesis guidance from students.

The students’ papers cover life sciences, mathematics, physics, chemistry, materials, computers and other fields.

None of the professors expected it.

Why did these freshmen, who were just sophomores, suddenly become interested in academic research?

The students at Huaqing Yan University are not as studious as you!

In line with the attitude of being responsible to the students.

Professors from various disciplines rigorously help students revise their papers.

You won’t know if you don’t look at it, but you will be shocked when you look at it.

Each of these papers is of extremely high quality, and many are landmark scientific research results in the discipline.

And the journals they want to submit to are all “nature”》、《science》、《ce11” a top academic journal.

Professors from various disciplines are happy to see this happen.

They became busy instantly, helping students format their papers, modify their paper formats, etc.

While busy.

The professors were all moved.

The overall educational and academic atmosphere of Rainbow University is really strong now.

And so on.

Students of Rainbow University will reach a new level in the academic field! .
