Solar cell research is officially launched.

Yang Xiaotao will also apply for research funds and subsidies as usual according to the rules of the institute.

This won't be given up just because he is the boss of the Nine Division.

Instead, this is a requirement in the rules.

And for subsequent research and development, he must also take it.

Otherwise, if he takes the lead, what will the people behind him think?

If Yang’s tribe doesn’t take money, then if I take it, wouldn’t it mean that I don’t have a high level of awareness?

Even if this continues, it will not affect the enthusiasm of some people.

"Old Ye, tell me."

After Yang Xiaotao confirmed that the plan was launched, he asked Mr. Ye to preside over the meeting.

Old Ye nodded, sat on the chair, and picked up his notebook, which were the information he had sorted out.

"Comrades."

"The solar cells we want to make, in layman's terms, convert light energy into electrical energy."

"So, what do you think is in the light?"

When Mr. Ye asked, Liu Hao said first, "There is color in the light, and the rainbow is the color of the light!"

Everyone nodded. These days, children are looking at the sun with candy paper, and the color is colorful.

Xu Hua pondered for a moment, then spoke, "There is still energy, and it feels hot when shining on people, just like a fire."

"According to physical research on light, most of the energy of light we come into contact with comes from the sun, and the energy inside can make objects burn..."

After Xu Hua finished explaining, Old Ye smiled and said, "Xiao Xu and Xiao Hao are right. There is indeed color and energy in the light."

"Summer is hot and winter is cool, it is all related to how much sunshine!"

"Then do you think, how do you use this energy in light to convert it into electrical energy?"

Liu Hao and the other four were silent.

They really don’t know the transformation principle, let alone how to do it!

Seeing this, Yang Xiaotao smiled and said, "In fact, solar cells have been studied abroad for a long time."

The four of them looked surprised when they heard this.

"Don't be surprised, the development speed abroad is indeed beyond our imagination in some aspects."

"Of course, this is also related to their environment. After all, our development time is too short, and it is still a bit worse than the accumulation of hundreds of years of research."

"However, I believe that with the efforts of our generation, this gap will be narrowed, or even surpassed the other party!"

After hearing what Yang Xiaotao said, all four of them were Zheng Keyou.

I can't catch up with me, so my children will continue to chase me, and my children will still chase me, and sooner or later they will surpass them.

"Yangbu, what are we going to do next?"

"Yes, what do you think we're going to do?"

Xu Hao and the others couldn't wait.

Since they are studying abroad, they cannot fall behind.

The rejuvenation of the great nation must be fought against time and caught up with everything!

"How to do it, we need to study it together!"

"However, before that, we need to figure out the principles of solar cells."

Yang Xiaotao asked the four of them to rest assured, and then looked at Mr. Ye.

Seeing this, Mr. Ye continued, "If you want to study solar cells, you must know a noun, photovoltaic effect."

"Many years ago, a French physicist discovered that some metal electrodes immersed in solution would have electric currents on them after being illuminated by light. He called this phenomenon the photovoltaic effect."

"The current generated by this is also the basis for the development of solar cells."

"Later, after more than a hundred years of research and development abroad, in the United States, some people found that crystalline silicon will receive electrons in the sun when it is exposed to sunlight!"

"In this way, on this basis, they made a diffusion PN junction that could be used for unidirectional conduction, and in this way, they created practical solar cells."

"This kind of PN junction is made of semiconductor silicon. It is reflected in unidirectional conductivity, which is to show low resistance at the forward voltage and high resistance at the reverse voltage."

"The two sides of an intrinsic semiconductor are diffused with different impurities, forming N-type semiconductors and P-type semiconductors respectively."

Mr. Ye tried to slow down his speech as much as possible, but he could tell from the reactions of several people, and probably not many understood them!

Old Ye also noticed the expressions of several people, so he continued, "What we have to do now is to make this PN festival."

Seeing this, when Yang Xiaotao was about to speak, Old Ye stood up from his seat, then took a pencil and drew pictures on the blackboard.

"This is a semiconductor pn junction..."

"When sunlight shines on the semiconductor pn junction, new hole-electron pairs will be formed."

"Under the action of the pn junction electric field, holes flow from N region to P region, and electrons flow from P region to N region. After the circuit is turned on, a current is formed."

"This is how photoelectric effect solar cells work!"

Slap

Everyone immediately applauded, and they knew what they saw when they saw the design drawings on the blackboard.

At least I know what to do.

"So, Mr. Ye, what is our current task?"

Yang Xiaotao asked everyone out loud.

Old Ye picked up the notebook and looked at it again, "Now the first one is to make a PN knot!"

"The high-purity silicon we use to study is now ready, which solves the problem of raw materials!"

"As for tools and equipment, we have them too!"

"So, all the conditions are met, and it is time to start research!"

Old Ye said firmly.

Although he knew the study was not as simple as he said.

But this is the first time he has been able to participate in research work in recent years.

He cherishes this opportunity very much.

In the last years, he will add another handful of fire to the country and the revolution, and make another heat.

"Okay, then let's make a PN knot first."

Seeing Mr. Ye say this, Yang Xiaotao made the final decision.

When everyone has a goal, they will naturally have motivation.

Not long after, the news of the establishment of the solar cell team spread in the Nine Divisions.

Originally, this kind of research project would not attract much attention. After all, the institute has been studying many major topics during this period.

There are many small topics under the big topic.

And solar cells are probably just a small issue.

But after learning that Yang Xiaotao was involved, this was no longer a small project.

You know, after the establishment of the Ninth Department, Yang Xiaotao, the director of the research institute, did not participate in any project.

The name does not count.

But now he actually joined the project team!

Not only that, in addition to Yang Xiaotao and Mr. Ye are also there!

Mr. Ye, that’s also the honorary dean!

From this perspective, how can the project that both deans participated in is simple?

For a moment, everyone speculated that what is the most powerful of this solar cell project?

Some people even thought about how to join the project team.

These are the two deans!

Seize the opportunity and you can fly at the rhythm.

Under such circumstances, everyone was very curious about the four newcomers. Many people began to inquire about the identities and past of several people, and some even regarded the four people as future stars.

In a word, these four people have become the envy of many young people.

After the solar energy research project was established, Yang Xiaotao threw all the preparations directly to Liu Lixue.

Yang Xiaotao felt it was very reasonable if he had something to do.
