Do you engage in scientific research?

Chapter 172
"Are you satisfied?" Ji Mo returned to Xianyu and asked with a smile.

Xian Yu nodded with a smile, seeing Suan Ni crying and laughing and the trembling appearance of the recruits, he felt much more refreshed, how could it be worthless to laugh at her.

In the next spare time, she began to learn shooting leisurely and seriously, and Suan Ni and the recruits he trained didn't even dare to look at her.

Leisurely days always pass very quickly. Two days later, Zhou Mei's mother finally sent all the materials they needed to the laboratory, and everyone's experiments were officially started.

The space solar cell they studied, also known as photovoltaic device, is a device that uses the photovoltaic effect to convert light energy into electrical energy, which is also the basis and core of solar photovoltaic power generation.

There are seven types of solar cells currently on the market: silicon solar cells, polycrystalline thin-film cells, organic polymer cells, organic thin-film cells, nanocrystalline cells, plastic sensitized cells, and plastic cells.

And these seven kinds of batteries can be subdivided into more types. For example, silicon solar cells can be subdivided into monocrystalline silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells.

Cells made of these different technical materials have their own advantages and disadvantages, among which silicon solar cells are the most mature and occupy a dominant position in applications.

In the classification of silicon solar cells, monocrystalline silicon solar cells have the highest conversion efficiency and the most mature technology, but the cost of monocrystalline silicon is high, and it is difficult to greatly reduce its cost.

Polycrystalline silicon thin-film solar cells are cheaper than monocrystalline silicon, but the disadvantage is low conversion efficiency.

Amorphous silicon thin-film solar cells are low in cost and light in weight, their conversion efficiency is not bad, and they are easy to mass-produce, so they have great potential.

But the disadvantage is also extremely fatal. Due to the photoelectric efficiency degradation effect caused by its material, its stability is not high, which directly affects its practical application.

If the stability problem and the conversion rate problem can be further solved, then the amorphous silicon solar cell is undoubtedly the best choice for the solar cell.

After comprehensive consideration, they unanimously decided to start with amorphous silicon thin film solar cells.

Several people who had never cooperated before got together because of a competition, but they got along very well when they started the experiment, with a clear division of labor and a tacit understanding.

The laboratory is boring and lengthy, requiring constant debugging of data and repeated operations. If one person does these tasks, he will definitely be driven crazy by these boring repetitions.

But it’s different when there are too many people. At least someone will chat with you for entertainment, and when you get stuck in a bottleneck, someone will encourage you to cheer.

Moreover, there is a big guy named Lei Yu who is also a foodie in the team, and their experiments went smoothly, and they even gained a lot of weight.

The days were peaceful and uneventful. After the experiment started, Kelly came to find them every now and then. There was no other reason, just to have dinner with them.Sometimes Alan and Emin Aaron would also come, and everyone tacitly did not mention anything about the competition, and only talked about the food customs of Country Y and Country Hua.

About a month before the competition, Kelly came to have dinner with the other four as usual, and Alan and Emin Aaron were also there, but today there was one more person in the team, a blonde with a very good figure lady.

Not only is he in good shape, but he is also good-looking, but the domineering and dismissive look on his face makes people feel a little uncomfortable.

Since everyone often eats together during this period, it is normal for friends to come and go, so sometimes Kelly and the others pay, and sometimes they pay when they are free.

And what's good today is that they treat guests in their spare time, which was agreed before the appointment, but they didn't know in advance that there would be one more person eating together.

They made an appointment to meet at the school gate, and when they saw Yu Yu and the others, Kelly came over and held Zhao Tian's hand, and the relationship between the two became better and better in the subsequent exchanges.

"This woman is Emily Brent, a member of our team. She likes my brother and has been pestering him. She must come with us today!" Kelly complained to them angrily.

"Then your brother can agree to her coming?" Zhao Tian asked.

After getting along for a month, they also got to know Emin Aaron to a certain extent. After shedding the aura of idol, Zhao Tian is no longer a little girl.

Emin Aaron is a typical aristocrat of country Y. The gentlemanly elegance in his bones makes him look extraordinarily charming, and he seems to have a very charming personality.

But in fact, this is also a very proud person, perhaps because he was born in a noble family, so he also has an innate pride.Treating unfamiliar people is always a gentleman and polite, but he doesn't take people seriously. Politeness is also a natural upbringing.

The treatment of acquaintances is much better, still gentlemanly and polite, but not so superior, with more human touch.

How could such a person treat Emily Brent, a suitor who entangled him, with a good face?Let alone let her come over for dinner.

Speaking of this, the resentment on Kelly's face became heavier, "Of course my brother doesn't agree with her coming, but we can't refuse her!"

"Why is that?" Xianyu asked Kelly while looking at Emily Brent. She felt that this Emily Brent seemed a little hostile to her. It's about to catch fire.

"Because her father is our father's partner, if we have a conflict, it will affect father's business." Kelly is doted on by her parents at home, and there are also brothers Emin Aaron and Alan this male outside. Friends doted on her, so she developed such a naive and lively temperament, so she never suffered this kind of grievance.

Out of consideration for her father, she didn't want to affect his business, so she swallowed her anger and acquiesced to Emily Brent's joining, but under the caring greetings of the other four, she was so wronged that she almost cried.

Such a beautiful and innocent little girl is crying, not to mention men can't bear it, women can't bear it either.

So Zhao Tian bravely gave Kelly an idea, "You and your brother can't offend her, we can, why don't we drive her away for you?"

Kelly's eyes lit up, "Is it okay?"

"Of course, it's us who drove her away, not you. If she wants to be angry, she will be angry with us."

"That's great, Tiantian, you help me get rid of her, I can't eat my throat without her." Kelly awkwardly used Chinese while she was happy.

It's a pity that the expressions of the four Chinese people present were a bit indescribable.

"Baby, that's called not being able to eat, or not being able to eat without throat." Liu Jia suddenly got into the upper body of the show, flirting with Kelly in a ruffian way.
