I have a Black Tech Ball

"Nana, I just acquired a factory that makes solar panels, and I need to send a trustworthy person over to help me manage it, I thought about it, and I think you're the most suitable." Zhang Ziang said.

Nana's heart was sweet as she heard Zhang Ziang's words: a trustworthy person... But Nana didn't immediately say yes, and after thinking for a while, she refused instead.

This was unexpected of Zhang Zion.

"I'm sorry Zion, I can't promise you, I haven't graduated yet, I'm not capable enough, I'm afraid..." interrupted Zhang Zion before he could finish.

"If it's because of that, Nana you don't have to worry, anyone's ability is cultivated slowly, I believe you will be able to do it, and the old factory manager from before is still there, I will let them assist you, I believe in you!"

After Zhang Ziang's repeated persuasion, Nana finally is agreed, now that Nana has almost graduated, many students in school have started to look for jobs, even if they are working now, it does not affect their studies.

Moreover, the school also supports college students to get out of school and adapt to the society as soon as possible.

The next day, Nana came to the Techno Ball Solar Company in a formal dress and Zhang Zion called everyone together for a meeting today.

"This is Miss Ouyang Nana, she will be the deputy director of the factory from now on, mainly responsible for the management of the inside of the factory." Zhang Zion introduced to everyone, "The factory director is still Zhang Xing, he is in charge of the sales side, the old factory director you are more familiar with the solar energy piece, in the future you will have to be more trouble ah."

"No trouble, no trouble, this is all I should do." Zhang Xing said evenly, in his opinion Zhang Zion was actually his savior, and the current situation was already the best result.

Although this factory wouldn't belong to him in the future, the external debt had been paid off and he still had some money in his hand, enough for his retirement.

Now it was a light weight.

"Please take care of Factory Manager Zhang in the future." Ouyang Na smiled and said.

"Where, where, where, it's the world of young people now, I'm almost unable to keep up with the pace of the times, and I really need to learn new knowledge from you guys." Zhang Xing was very kind, he understood Zhang Zion's purpose in sending Ouyang Na, and from the close relationship between these two young people, he could already tell a general idea.

This was likely to be... the future boss's wife ah, Zhang Xing naturally could not put on a show.

Back to the topic at hand.

"To be honest, our factory's previous performance was not good, and a large part of it is that our technology is still not cost-effective enough to satisfy our customers." Zhang Ziang said.

Zhang Xing nodded his head, he did not deny this point.

"I also know that this kind of scene is not just our factory, other factories are no better, similar to us, only a few companies can survive, the most fundamental reason is that there is simply no breakthrough in the current technology!"

It is true that in the solar energy sector only a very few manufacturers can get profits, their product photoelectric conversion rate is relatively high.

The photoelectric conversion rate of the current solar panels of the technology ball solar company can only reach 15 percent, while other manufacturers have been able to reach 17 percent.

Although there is only a difference of two percentage points, the gap has been closed.

Tech Ball Solar's previous product was mainly polycrystalline silicon, and its photoelectric conversion rate was 15 percent.

The by-product is monocrystalline silicon solar panels, which can reach a photoelectric conversion rate of 20 percent, but the cost is greatly increased, and is simply uneconomical.

Zhang Ziang swept around, "If we, the Technology Ball Solar Company, want to make a breakthrough, then we must innovate and lead in terms of technology."

Zhang Xing was deeply impressed, he nodded his head, but everyone understood the reasoning, but was it that easy for the technology to make a breakthrough, he drew a big question mark inside his mind.

"You should also know that there are three types of materials for solar panels now, monocrystalline silicon, polycrystalline silicon, and one is thin film."

"Most of them are polycrystalline silicon on the market, a small amount of them are monocrystalline silicon, but you can rarely see a thin film, we'll start with the thin film this time!"

"Look, everyone!"

Zhang Zion took out a small piece of black film from the inside of his pocket, measuring approximately 20mm long by 20mm wide.

"I never fight unprepared battles, and the reason I've acquired this solar panel factory is not because of Zhang Xiaoyu's face, nor on a whim, but on a well thought out basis!"

"This piece of film in my hand is the latest research result of our company, codenamed Black Hole!" Zhang Ziang tossed his voice, "Don't underestimate this little film, but it guarantees a staggering ninety percent solar conversion rate!"

"Ninety percent!" Zhang Xing stood up in surprise after hearing this, his eyes widening very wide, "This is impossible, with the current technology let alone ninety percent, even fifty percent no company can do it!"

"Just because someone else can't do it, doesn't mean we can't do it, who are we? We're a tech ball company!" Zhang Zion likewise stood up, "If you don't believe it, Plant Manager Zhang Xing, you can take this piece of black hole film and test it, I believe a lot of it will yield results."

Zhang Zion handed the film to Zhang Xing.

Zhang Xing couldn't care less about the meeting, he immediately went out, he was trembling all over as he went out, although he was holding just a piece of film in his hand, light as a feather, he felt as heavy as Mt. Taishan!

This black hole film was naturally produced under the guidance of the small ball, the rational use of solar energy was one of the standards of a civilization, and the small ball already had mature technology there.

There was even more than one kind of film, and the film taken out now was merely one of them.

Zhang Zi Ang has now completely mastered the manufacturing method of black hole film, ten percent rosin, ten percent insect glue, twenty percent plexiglass, thirty percent polystyrene plus some materials, mixed together in a certain order for a certain amount of time, after the catalyst, the black hole film will be synthesized.

It's simple to say, but when to add what materials, how much to add this is all confidential, not to be divulged!

The black hole film lets in as much sunlight as it wants, but locks the heat in and keeps it out, so it can only go in and out!

Ten minutes later, Zhang Xing ran over with excitement in his eyes, "It's incredible, it's really incredible, how could there be such a film, it really did it, the solar energy conversion rate can really reach ninety percent!"

Nowadays, the parity rate of solar panels is only about 20 percent, and a square meter of solar panels can supply about 230 watts of power, although there is fluctuation up and down, but the difference is not big, there will not be a qualitative difference!
