International students returning to 90

"This is the final report on the flat ground independent solar photovoltaic power generation system." Lin Yi distributed several thick documents to the researchers.

"Yesterday, several teams stayed up all night to make a detailed analysis of the flat-type independent solar photovoltaic power generation system from the aspects of photoelectric conversion sensitivity, current and voltage data, and current stability. The analysis report I have compiled is in your hands."

The meeting room was so quiet that there was only the sound of flipping papers.

The more Simpson looked at the smile on his face, the bigger he was. He suddenly slammed the table, and the voice was so loud that everyone jumped, "No, no! I have to endure it for two more days... two more days..."

A group of researchers...

Lin Yi coughed twice, "The test results of the flat independent solar photovoltaic power generation system can explain a lot of problems. Our all-solid-state dye-sensitized solar cells performed well in the field test, and the photoelectric conversion efficiency is not much different from the laboratory data. , but because of the characteristics of sunlight itself, the current stability of the photovoltaic power generation system is not satisfactory."

Researcher Harris pushed his glasses, and said: "In the existing solar power generation system, solar power generation does not exist independently. Our all-solid-state solar cells make solar panels more effective in terms of safety and size. It is possible to spread it out in an all-round way, but it is still difficult to achieve a separate power supply."

"The main reason is that the battery technology is not good enough." Lin Yi whispered to himself.

Solar energy is a natural resource, but at the same time, it is affected by limiting factors such as weather and environment, such as the atmospheric environment and climate, so even before Lin Yi was reborn, there were very few solar systems with independent power supply in the world.

Of course, apart from objective environmental factors, Lin Yi believes that the biggest obstacle to solar power generation technology is probably the failure of battery technology.

He pursed his lips and underlined the word "battery" in the report.

"However, as long as the environment is suitable and the area is large enough, our current finished product can almost cover about half of the electricity consumption."

"That's right, our finished product can be fully spread on the roof. Given the latitude and climate of the United States, it's not a big problem!"

The researchers were relaxed in tone. Yesterday’s test results were obviously better than they imagined. The flat-bottomed independent solar photovoltaic power generation system has been running for nearly 20 hours now, and no reverse charging or reverse charging has occurred.

And after the sun went down yesterday, Lin Yi commanded the technicians of the power plant to connect the power interface of the office area of ​​the power plant to the independent solar photovoltaic power generation system. District power supply.

"It's still a battery technical problem. I asked the meteorological department for data overnight. As far as San Francisco is concerned, precipitation is mainly concentrated in summer. The 'normal' weather like yesterday accounts for about two-thirds of the whole year. In the past ten years, the longest rainfall duration in San Francisco is 32 days, and we have done charging and discharging tests of various types of batteries on the market, taking yesterday’s battery office area as an example, under no sunlight, the maximum continuous power supply is 20 hours!"

32 days and [-] hours, this contrast made the entire meeting room fall into silence.

"Okay, if everything is really satisfactory, and oil and coal, those oil tycoons in the Middle East can collectively hang themselves with their belts." Lin Yi knocked on the table with a pen, hoping that solar energy could really To compete with coal and oil, battery technology and higher photoelectric conversion efficiency must be solved.

But food needs to be eaten bite by bite, and the road needs to be walked step by step. Not to mention that Lin Yi does not have the battery technology, even if he has it, he dare not take it out all at once. Those countries and individuals who rely on oil for food, when it comes to the real life and death, God knows what will happen.

Lin Yi didn't want to go through the bloody drama of secret agents, rescue, and life and death moments in those American blockbusters.

"The goal of our first-generation project results is very clear, to alleviate the current situation of energy shortage in the world today, and to do our part for the world's energy industry!" These words were so righteous that both Simpson and Logan looked up at him several times .

"It's almost done, let's go to test the rooftop independent solar photovoltaic power generation system." Lin Yi stood up first as he said.

When the researchers in the meeting room heard the words, they also stood up and walked out in twos and threes. Lin Yi pushed open the door of the meeting room, only to see James striding over anxiously.

"Researcher Lin...something has changed!" He was followed by two Americans whom he hadn't seen yesterday. They were dressed in suits and leather shoes, and they looked like they had been in high positions for a long time.

Lin Yi frowned, and he glanced through the window, "Is the weather fine? Has anything changed?"

James smiled wryly, this was also his mistake at work.

"It's an employee of the power plant who posted photos of the on-site solar experiment on the forum, and now the outside of the power plant is surrounded by media personnel. I haven't stopped calling this morning." James wiped the sweat from his forehead.

"Researcher Lin, hello. We have already dismissed the employees involved in this matter. If Simpson wants to pursue his legal responsibility, American Electric Power will cooperate." The speaker was one of the two Americans behind James. .

"For the next experiment, we will fully cooperate, and American Electric Power will do our best to communicate with the media. Make sure Simpson has a good experimental environment." This person spoke very sincerely.

Seeing his boss speak up, James hurriedly explained: "These two are Mr. Walker, the executive vice president of American Electric Power, and his assistant. American Electric Power attaches great importance to Simpson's experiment..."

It's important. After the news spread in the forum yesterday, James was scolded by Mr. Walker before he could sleep well, saying why he didn't report this kind of thing to the headquarters...

He wanted to report, but he had to wait for the results. Last time, he reported something early. Maybe it was because his superiors said he couldn't hold his breath. Oh, he was too late this time.Okay, you are the boss and you are always right.

Then, before he finished his breakfast the next day, Walker and his assistant were already waiting at his door, and he only ate half of his omelette.

"Thank you very much, American Electric Power for supporting our laboratory!" Simpson received Lin Yi's eyes, and his teeth itched with anger, but who told him that he was the person in charge of Simpson in name, he still had to deal with what he had to deal with.

"Let's go, let's go to experiment." Lin Yi said to James with a smile.

James secretly glanced at Walker, and suddenly felt in a good mood, "Okay, okay, everything is ready, let's go this way." He puffed out his chest, he was engaged in technology, he and Researcher Lin were the ones along the way , You Walker, stay where you are cool.

For Lin Yi and others, compared with yesterday's flat type, the roof type independent solar photovoltaic power generation system is more important to them. Compared with the flat type's requirements for the site environment, the roof type can really enter the family and realize Fully popularized solar power generation technology.

When Lin Yi proposed the rooftop independent solar photovoltaic power generation system, he once described the future blueprint of this project with them.

"Energy is a resource. What can resources do? Look at those countries in the Middle East that have developed on the basis of oil fields. They have oil, but we don't, but everyone has solar energy. Imagine that the roof of every household can be used as a point to collect solar energy. The dots are strung together to form a thread, and the thread is woven into a net. There is an old saying in Huaguo that a fire can start a prairie fire, and it is also suitable for this.”

"Not only that, if residents provide roofs to collect solar energy, should we give corresponding compensation or electricity fee reduction? Another example, they not only provide roofs, but also purchase solar power generation equipment by themselves, and then sell the electricity to the power company for grid connection? Then the residents are equivalent to having a new fixed income!"

This is the "photovoltaic poverty alleviation project" often mentioned by later generations. In fact, this project itself is good. With the advancement of urbanization, young and middle-aged people in rural areas have moved to cities, leaving behind many empty-nest elderly people who have no source of income and fall into poverty.

It would be great for them and their children if they could have a regular source of income.It is better to teach people to fish than to teach them to fish. The original intention of the solar photovoltaic poverty alleviation project is to teach people to fish. Photovoltaic poverty alleviation projects have been controversial.

But in the United States on the other side of the Pacific Ocean, Lin Yi is confident that the whole project will be carried out.This can be regarded as helping to gain some experience in the future.

"What about the media?"

Lin Yi looked at James with a smile, "Mr. James, didn't you say that the media was blocked by the security guards, so keep blocking it."

James laughed dryly, ancestor, it's easy for you to say, the outside media are not low-level tabloids, American Electric Power is the one that blocks people, and American Electric Power is the one that offends people.

"How about debugging?"

"The roof slope of the bungalows in the living area of ​​the power plant is not steep, and the solar panels have all been installed."

"Okay, after the data comes out, the rooftop independent solar photovoltaic power generation system will be connected to the living and office area for power supply, and the flat independent solar photovoltaic power generation system will be turned off at the same time."

"no problem!"

"Prepare!"

"three two……"

Lin Yi hadn't called out "one" when the loud sound of the helicopter's wings came to his ears. Everyone looked up and saw a plane with the New York TV logo painted on its fuselage flying from a distance. The plane didn't fly high , everyone could clearly see that there was a person on the plane with a video camera who didn't know the camera was taking pictures of them.

Lin Yi looked at James slightly annoyed.

James: "Researcher Lin, our security guards can stop the cars on the ground, but they can't stop the planes in the sky!"
