Village chief, your township enterprise sells laser cannons?

Chapter 138 has a subsidy! (Third update!)

Moreover, these net cages can be used to raise not only eels, but also other types of fish!

Raising one is a win!

After placing the hard drive containing the wire mesh cage, Lin Man picked up the hard drive containing the perovskite-silicon tandem photovoltaic power generation technology between two fingers and examined it repeatedly under the energy-saving lamp.

After examining it for a while, he used the system to open the data in the hard drive and began to browse through the information.

Soon, Lin Man found the core of the information.

A novel crystal-making technique is used to anchor perovskite crystals, thereby enhancing their stability.

This technology is somewhat similar to the hydrogen metal self-combination technology we obtained previously.

Seeing this, Lin Man logged out of the system, picked up his phone, and began searching for photovoltaic power stations in Northwest China on Douyin.

The reason why photovoltaic power generation can occupy half of the new energy field is due to China's massive stimulus policy over the past decade.

Over the past decade or so of massive photovoltaic development, photovoltaic power generation has evolved from polycrystalline silicon to monocrystalline silicon, and now, crystalline silicon photovoltaic power generation is approaching the theoretical limits of materials.

To further improve efficiency, we need to change the materials.

The most ideal material is perovskite.

Perovskite originally referred to a natural mineral discovered in 1839 by German mineralogist Gustav Ross in the Ural Mountains of Russia.

The main structure of this mineral is calcium titanate.

Later, with the development of science, scientists found a special crystal structure inside this mineral, ABX3.

Since then, the term perovskite has moved beyond its use as a natural mineral and become a general term for artificial materials with this specific crystal structure.

This type of synthetic material can absorb sunlight more efficiently than monocrystalline silicon, and the electrons and holes it generates can travel further, resulting in higher power generation efficiency.

It is a favorite of various photovoltaic power generation laboratory research.

After years of research, scientists discovered that this material can be modified by changing the proportion of elements in its formula, like a palette, to adjust which color of light it absorbs. Based on this premise, a new technology was born, called perovskite-silicon stacking technology.

The same photovoltaic panel is divided into two layers: the upper layer is a perovskite panel, and the lower layer is a traditional monocrystalline silicon panel.

To further improve power generation efficiency.

Furthermore, perovskite is cheaper than monocrystalline silicon, and perovskite panels can be made very thin, even coated on flexible substrates such as plastic and metal foil, allowing the originally rigid photovoltaic panels to be rolled up, thus reducing transportation costs.

However, every advantage has its disadvantages. The disadvantage of perovskite is that it is not very stable.

This stuff is very sensitive to water, oxygen, high temperature and ultraviolet light, and it degrades very easily in the natural environment.

Therefore, this technology is in a stage of application, but has not yet been fully rolled out.

but now!

This stuff can be spread out and used all over the country.

To promote photovoltaic power generation, China has divided solar energy resource areas into four categories based on the amount of sunshine in each region.

In some regions, the sunshine duration is extremely long, with an average peak sunshine duration of about five to six hours per day.

In Category II areas, the average peak sunshine duration is about four to five hours per day.

In the third category of areas, the average daily sunshine duration is three to four hours.

In the fourth category of areas, the average daily sunshine duration is two to three hours.

Built according to standard photovoltaic power station construction standards, a perovskite tandem photovoltaic power station covering ten acres with a photoelectric conversion efficiency of 43% would be constructed.

The power plant's theoretical peak total power can reach approximately 1863 kilowatts, with a system overall efficiency of 80%.

In one type of region, it is conservatively estimated that 7452 kilowatt-hours of electricity can be generated per day.

In Category II areas, it is conservatively estimated that 5961 kilowatt-hours of electricity can be generated per day.

In the third category of areas, it is conservatively estimated that 4471 kilowatt-hours of electricity can be generated per day.

In the fourth category of areas, it is conservatively estimated that 2980 kilowatt-hours of electricity can be generated per day.

With the same land area, a traditional monocrystalline silicon photovoltaic power station, even in Class I areas, can only generate 3000 to 4000 kilowatt-hours of electricity per day.

In Category IV regions, the daily power generation is only about 1000 to 1500 kilowatt-hours.

The numbers are there, no need to compete or fight for them!

Once this technology is developed, it will be able to decimate the traditional monocrystalline silicon photovoltaic power generation industry.

If those people in the Northwest were ruthless enough, they could easily cover the entire desert with power plants!

The thought of covering all the deserts with such photovoltaic panels made Lin Man chuckle. Those are hundreds of thousands of square kilometers of desert; covering them would require a huge sum of money.

And he can basically keep this large sum of money for himself!

That's all money!

Thinking of the bright red banknotes, Lin Man couldn't help but take out the golden bust from the system's inventory and casually stuff it under his pillow.

I rested my head on it for a while, then simply stuffed it into the system repository.

It's so uncomfortable on my head!

Take a break first, and when Wang Ju comes back, have him liaise with a design institute to design the factory. At the same time, have him get two sets of perovskite production equipment. Once the equipment is back, he can get some photovoltaic panels to cover the factory building for his own use.

Every little bit of electricity saved counts.

As soon as the light was turned off and his eyes were closed, Lin Man drifted off to sleep.

On the other side of the village, Liu Guoming was studying the requirements for compulsory education issued by higher authorities.

After looking at it for a while, he finally picked up a pen and wrote the words "mental illness" on the notebook.

After thinking for a moment, he crossed out the words "mental illness" and replaced them with other words.

"Level 2 mental disability," followed by a parenthesis with five words written inside.

He has self-harm tendencies!

After writing those words, Liu Guoming's hand remained motionless for a long time, holding the pen. After a while, he put the pen down, tore off the page with a solemn expression, and finally took out a lighter to light it.

The smell of burning paper reached Liu Guoming's wife outside the study. She quickly brought in a basin of water and saw that it was Liu Guoming burning paper on his own initiative. She put down the basin and complained, "Why are you burning paper so late at night? It's so unlucky."

"If you're in the mood to burn paper money in the middle of the night, you might as well get up early tomorrow morning, ask Secretary Lin for leave, buy some fruit and pig's head, drive back and pay respects at your ancestors' graves."

"No need!" Liu Guoming shook his hand and threw the paper into the ashtray. "Staying here as the principal was my own choice."

"Secretary Lin was willing to spend a lot of money to keep me as principal because I have worked diligently here for many years and he has seen my contributions."

"It has little to do with our ancestors."

"What I need to do now is to return the favor."

The papers in the ashtray had burned out. Liu Guoming beckoned to his wife, "Come here!"

His wife walked over with a face full of questions, just as she was about to ask, Liu Guoming turned around, picked up a pen, and wrote a few words on the paper behind him.

Subsidies for disabled children.

After writing those words, Liu Guoming rested his hands on the table and looked at them for a while, then wrote three more names next to them.

He Yaoyao, Li Junjun, Long Hao.

After writing down the three names, Liu Guoming said, "When the village voted to establish a primary school, the parents of these three children strongly opposed it, especially He Yaoyao's maternal grandmother, He Xiaozhen, who even filed a complaint."

"Now that the procedures for establishing the primary school have been completed, they can attend the school near their residence in accordance with national laws."

"I'm not a god, I'm just an ordinary person, an ordinary person who wants to stay true to myself amidst the tides of the times, but now I don't want to stay true to myself anymore."

"I want to trip them up, but I need your help with that. Are you in?"

Looking at the three names, Liu Guoming's wife blinked, looked up, and asked earnestly, "Is this Long Hao the son of the repair shop owner at the intersection?"

"yes!"

"I remember his dad reported you too, right?"

"Yes, it's about the student trusteeship."

Having received confirmation from her husband, Liu Guoming's wife nodded and asked, "What should we do?"

His wife's words made Liu Guoming refocus his attention on the paper in front of him. He pointed to the words "disabled children subsidy" and said, "I will go to Secretary Lin tomorrow and add a clause to the announcement of the newly established primary school that tuition and living expenses for disabled children will be waived."

"You've played mahjong with He Xiaozhen and the others, so you know their personalities. They like to haggle over every little thing and are greedy for small gains. If they see something like this, they'll definitely ask a question."

"So, when you play mahjong with them, you need to tell them that you have a level two mental disability, which is considered a disability."

"They can also receive subsidies. Another key point is to tell them that the effect will be better if they have a level 2 mental disability plus self-harm."

After listening to her husband's instructions, Liu Guoming's wife fell into thought, gesturing with her hands: "I need to tell them that a level two mental disability is a disability and they can receive subsidies."

"And it would be best to add a self-harm tendency as well, right?"

"That's right!" Liu Guoming nodded, but the next second, his wife asked with a puzzled look, "Why do you say that? You're beating around the bush!"

Liu Guoming picked up a lighter and burned the piece of paper with writing on it, while lowering his voice: "I can't possibly throw them into the sea to feed the sharks, and according to the regulations, I can't refuse their enrollment without a reason."

"However, there are grounds to refuse their admission."

"A person with a level two mental disability plus self-harm falls into this category, and we can refuse to admit them on the grounds that we are afraid they will harm other students."

"We're betting on those few who are greedy and trying to get something for nothing!"

"Of course, if others are looking for a bargain, then it's like we're screening them out in advance."

"You—" Liu Guoming's wife stammered for a while, then sighed and hugged Liu Guoming. "Relax, don't put pressure on yourself. I'll go play mahjong with them tomorrow. School starts soon, they should be happy to play mahjong with me. It's too late tonight, let's rest first."

"Principal Liu—sigh—let's do it your way!"

In the village committee office, after listening to Liu Guoming's idea, Lin Man reached out and picked up the notice in front of him, then picked up a pen and added a sentence at the end of the notice.

Supporting documents are required.

After writing this sentence, he handed the notice back to Liu Guoming, then looked up and said, "Actually, I didn't think it was that complicated. These families are just buying the original owners' houses."

"Only the person who bought the house has registered their household registration; the others are not registered."

"You could take them out with just one sentence, but you're in a bit of trouble."

Liu Guoming shook his head: "But this insurance policy of mine will stay with them for life, won't it?"

These words sent a chill down Lin Man's spine. He looked up at Liu Guoming in front of him as if he were seeing him for the first time.

Noticing the surprise in Lin Man's eyes, Liu Guoming sighed softly, "How should I put it?"

"You can see this as a rebellion against my decades of peaceful life, an act of evil."

"I came here to be a teacher in my twenties. From teacher to principal, in more than ten years, I feel like I've changed several times."

"Everyone was reasonable at the beginning. When there were problems, we solved them together; when there weren't, we all worked together positively!"

"But now, I find that the people I come into contact with seem to have changed; they've become unreasonable."

"If there's no problem, we create one; if there is a problem, we don't think about solving it, we only think about exacerbating it."

"So, I decided to do something evil once, to become a bad person, and see what changes will occur after becoming a bad person!"

'

"Also, Secretary Lin, if I become abnormal later, please send me directly to the 402 Hospital."

Listening to Liu Guoming's explanation, Lin Man let out a soft sigh. He had heard similar cases from his lecturers when he was preparing for the selection exam for civil servants.

Grassroots cadres who work on the front lines year-round encounter all sorts of people every day, which means they are constantly exposed to negative emotions.

When people absorb too many negative emotions, to the point that they can't regulate them, they'll want to indulge themselves.

That one indulgence led to disaster!

Liu Guoming is currently on the verge of letting himself go.

However, his indulgence—

He sighed, raised his right hand and waved gently to Liu Guoming: "Go and organize the work quickly, get the enrollment plan and registration done, and we can start working once our teachers arrive."

"I'll go right now!" Liu Guoming nodded, picked up the revised notice from Lin Man, and turned to leave the village committee office.

Back at the elementary school, he reprinted the revised announcement and posted it on the bulletin board at the school gate.

Then take another photo and send it to Lin Man.

Lin Man received the message and then broadcast it to the village through the village committee's loudspeaker. After notifying the village, he also sent the message to Long Kaixiang and others via WeChat.

Meanwhile, Liu Guoming's wife was dispatched.

She changed her clothes and called for mahjong partners in a WeChat group on her phone.

Before long, the six people sat down at a table and took turns playing the game.

And among these six people, there happened to be He Xiaozhen and a few others.

While playing mahjong, the women also chatted, exchanging information they had heard over the past few days: "Have you heard? Lin Lao Si's company is hiring cleaners, and the pay is pretty good!"

"Two foreigners are staying at the hotel in the village. They seem to be quite wealthy."

"You're so old, and you're still thinking about going to see foreigners? Don't let them break you!"

"Foreigners stink horribly, who wants them!"

"Hehe, we didn't mention foreigners, you brought that up yourself—"

Amidst the discussion about foreigners, Liu Guoming's wife casually asked, "What was that announcement over the village loudspeaker about just now?"

The person next to him immediately chimed in, "They said there was some kind of subsidy, and we were told to collect it!"
