However, what Chen Weidong is worried about is not patent issues.

They have some relationship with Toyota, so there should be room for negotiation.

Even if the other party refuses to give in and insists on using patents to block them in hydrogen energy, then just go ahead and do it. Anyway, they are not the only ones with patents. Infinite Company also has a huge number of patents in electronics, machinery, materials, etc.

When the time comes, no one will be able to make it easier.

Chen Weidong lowered his head and said nothing.

The conference room also became quiet.

Researchers from several departments are waiting for his final word.

The company's development direction over the years has been guided by Chen Weidong, and there has never been any deviation.

Even looking at the world, Infinity Company is definitely one of the best in commercializing scientific research and technology.

Unlike other company bosses, after getting rich, they blindly enter a certain field as soon as their brain gets excited, and in the end the project fails, resulting in a huge waste of funds.

Therefore, whether it is a tram or a hydrogen energy vehicle, as long as Mr. Chen decides, they will make every effort to do it well.

Chen Weidong's thoughts came to him in a trance, and he smiled and said: "Everyone thinks that developing electric vehicles is more direct and saves trouble. There are various concerns about hydrogen energy vehicles, which is completely understandable."

"After all, hydrogen storage is indeed a worldwide problem."

"But, I wonder if you have heard of the term "energy closed loop"?"

Many people heard this word for the first time and had puzzled expressions on their faces, but some researchers felt thoughtful.

Chen Weidong continued with a smile: "Many of us don't recognize trams as new energy, simply because the electricity used by trams is not entirely renewable energy, and most of it needs to be generated by fossil fuels."

"So, if we change our thinking and use solar energy to generate electricity, and then electrolyze water to produce liquid hydrogen, and then store the hydrogen and use it in hydrogen energy vehicles, is it possible to achieve it?"

Fang Weimin's eyes lit up, and he stumbled a bit when he spoke excitedly: "This... This is simply the most perfect energy solution! Solar energy is a renewable and infinite energy source, and using it to produce liquid hydrogen can reduce the cost to one

To an extremely low degree, we can crush the high cost of hydrogen production in island countries. As long as we solve the problems of hydrogen storage and transportation, we can achieve a truly closed energy loop! However, Mr. Chen, do we have such high solar technology?"

Solar energy does have many advantages, but its photoelectric conversion efficiency is also really low.

"Haha! Mr. Fang, we already have this technology!"

Zhao Gong smiled and opened his laptop, then entered a series of passwords and clicked on one of the folders.

"As we all know, monocrystalline silicon solar cells are a traditional battery model and one of the earliest topics we conducted research on."

"The best laboratory level in the world now is an effective conversion rate of 28%. We started research in this area relatively early, so we reached the theoretical limit of 33% eight years ago.

, and then turned to research on concentrating multi-junction solar cells...."

Fang Weimin was shocked by the data he said. He only joined Infinity Company in 2003, but he never expected that the company's research on solar energy had already reached such an in-depth level before that.

This achievement is simply amazing and completely worthy of pride!

However, he knows that the conversion efficiency of monocrystalline silicon and polycrystalline silicon solar energy is limited, and the cost of these flat solar panels is generally high, has no practical value, and will certainly not be used as the focus of energy development.

"In order to prevent sunlight reflection and maximize the use of solar energy, we passivated the surface of the crystal..."

Gong Zhao clipped a mini projector to the computer screen and projected the image onto the wall so that everyone could see his demonstration.

Chen Weidong had already read the relevant information, but he still kept smiling and had no intention of urging.

These achievements are the result of researchers who have devoted themselves to scientific research for ten years.

Even if it was just encouragement, he would use the most focused expression to express his heartfelt appreciation to these scientific and technological workers.

Scientists are not just admiring themselves, they also long for glory and the recognition and understanding of others.

Zhao Gong occasionally looked at Chen Weidong and found that he seemed to be listening with great interest, and his mood became even higher.

Every research project is explained in great detail.

"...Concentrated multi-junction solar cells, after unremitting research at our African base and the Solar Energy Research Institute, the results are also very gratifying..."

Gong Zhao opened a demonstration document, which was a data model calculated by a supercomputer.

In their usual research, they always look at design drawings and related data. In order to give Chen Weidong and Lin Zeju a more intuitive experience, they made this animation demonstration.

Chen Weidong immediately cheered up and listened to his explanation with real concentration.

The picture shows a square battery panel with many condenser lenses connected as a whole. Each lens is about 30 centimeters in diameter.

Below is an alloy film.

At the position where the lens light focuses, silicon wafers several millimeters in size are embedded.

At the bottom is a large heat dissipation device.

"This is a concentrating multi-junction solar cell we developed. Because it uses multi-layer alloy and ion implantation technology, three solar conversion layers are stacked on the same thickness of 20 millimeters."

"It can absorb three different solar outputs: visible sunlight, invisible ultraviolet light, and infrared light. The conversion rate reaches an astonishing 52%, which greatly breaks through the bottleneck of modern technology that can currently be achieved."

"With the same thousand-fold focusing, the power output of one square meter of solar panels can reach 1.4 kilowatts."

"One square kilometer of solar power generation can provide approximately 1 million and 5 kilowatts of electricity per hour."

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "If there are 100,000 square kilometers, all of which are used to develop solar energy, it can almost meet the power demand of the whole country!"

The more he talked, the more excited he became. Finally, he walked to the bottom of the country map in the conference room, pointed to a location and said:

"In the northwest region of our country, there are a lot of wasteland and deserts. These places can be opened up and used as solar power stations."

"The northwest region has very little rainfall, and the sunshine lasts for up to 3,000 hours a year, and the intensity is very high. It is an ideal location for the construction of solar power plants."

Lin Zeju laughed: "One hundred thousand square kilometers! Then let me ask, what is the cost of one square meter of concentrating multi-junction solar cells?"

Zhao Gong was speechless for a moment and was stunned for a long time before sighing.

Now even the most common flat-panel solar cells cost more than 3,000 yuan per square meter.

The cost of this special concentrating solar cell was more than 100 times that of ordinary solar cell wafers at the earliest!

Although after eight years of improvement, manufacturing costs have dropped again and again, and they have also developed a series connection technology in which several solar panels share one wafer board, the cost per square meter is still not less than tens of thousands of yuan.

In terms of power generation costs, it has decreased, but in terms of total investment, it has actually increased.

Based on this cost calculation, the construction of one square kilometer of solar power station requires an investment of approximately 2 billion yuan!

No matter how rich the company is, it cannot afford such high construction costs.

It is impossible for the country to pay for such a large expenditure.

They have mastered this technology for many years, but they only produced a few batches when they were fishing for the American consortium at the beginning of the century and later supporting African bases.

Technically, concentrating multi-junction solar cells have fully reached practical capabilities.

However, because the manufacturing cost is too high, it can still only be manufactured in laboratories and on a small scale.

Popularization is still a distant dream.

He returned to his seat, sat with his head down for a while, then raised his head and said in a firm tone: "We will make every effort to continue to reduce costs and make mass production a reality."

"I believe that solar energy will become one of our main sources of energy in the future!"

Chen Weidong took the lead in applauding gently: "That's very well said! We conduct scientific research to serve mankind."

"I very much look forward to your research achieving greater results!"

He turned his head, exchanged a few words with Lin Zeju in a low voice, and then asked seemingly unintentionally: "If I have a condensing lens with a power of 1,800 times, can you improve the current concentrating multi-junction solar cells?"

?”

"Eighteen hundred times!"

Fang Weimin screamed in horror, "I heard that the latest model of the American satellite is only equipped with a focusing lens with a power of 1,600 times! At the focus, the temperature reaches more than 1,800 degrees. This is not a difficult task.
