The rise of nanometers

A press conference of Dragon Totem caused turmoil in the global stock market.

The photolithography semiconductor industry has completely retreated, making Xizhou semiconductor companies, which were still somewhat ambiguous before, even more dependent on textile semiconductors.

Even if the Netherlands has ASML, a lithography giant, they are very helpless. STMicroelectronics, Infineon and NXP really want to maintain the lithography industry chain. However, the textile method is too powerful and directly suppresses the lithography method. .

Judging from the current situation, the semiconductor companies in Nanbo Bay such as TSMC, UMC, and MediaTek, which have a single industry, are probably in danger.

And the three stars of Goryeo will shed their skin even if they don’t die.

Japan occupies part of the upstream of photolithography semiconductors, and its influence is also very huge. Currently, it can only rely on orders from Intel, GlobalFoundries, and Texas Instruments to barely survive.

In other words, photolithography semiconductors in Northeast Asia have basically been crippled.

The next step is to see how the Textile Law Semiconductor Alliance deals with semiconductor companies in these three regions.

The disastrous failure of photolithography semiconductor companies has triggered a chain reaction that has begun to expand a little bit and is also gradually fermenting. It is estimated that there will be big changes around June this year.

the other side.

Huang Xiuyuan's stand-in robot came to the Dragon Totem Light Energy Research Institute in the Sun Valley Industrial Park. Du Jinhua, who has been responsible for Snail Industrial Technology, was also in the industrial park recently.

Hearing Huang Xiuyuan approaching, Du Jinhua hurriedly came out to greet him.

"Mr. Huang, welcome to Sun Valley for guidance."

He smiled and shook his head: "Don't look outside, take me in and take a look. I heard that you have developed a good thing."

Du Jinhua showed a hint of pride on his face: "Yes, Mr. Huang, please come with me."

A group of people entered the Light Energy Research Institute.

Inside the institute, Du Jinhua introduced him to Chen Jianxian, the chief researcher of the Institute of Light Energy.

This researcher is also the youngest chief researcher in the Suiren Department's Scientific Research Department. He became the chief researcher at the age of only 27. Without two brushes, it is unlikely that he would have been promoted.

"Chairman, I'm very happy to meet you!" Chen Jianxian reached out his hand excitedly.

Huang Xiuyuan also smiled and shook hands with the other party: "We are all our own people. Don't hide the fruits of everyone's efforts. Let me open my eyes."

"The chairman is laughing." Du Jinhua told Chen Jian to behave well.

Chen Jianxian naturally understood that the chairman came over to inspect the results. If the chain fell off at the critical moment, then they would be sorry for their efforts.

In the institute's solar panel preparation laboratory, Chen Jianxian took out a newly synthesized solar panel and introduced it like a treasure:

"Chairman, this is our latest new technology. Through the composite nano-opal structural layer, the light wave resonance effect of the silicon nano-layer can be greatly improved on the solar panel, thereby achieving carrier multiplication."

Huang Xiuyuan picked up the solar panel. It looked similar to an ordinary composite solar panel, but a layer of nano-opal structure was added inside.

Previously, on gold nanorod particles, it was because of their special nanostructure that the gold nanorods could produce a resonance effect on near-infrared light.

The opal nanostructure layer on the new solar panel also utilizes the resonance effect of special nanostructures on light waves.

This opal nanostructure can enhance the resonance effect of the silicon nanolayer, thereby increasing the number of carriers generated, and the number of carriers is actually the inner core of solar power generation.

Doubling the amount of carrier excitation means doubling the power generation.

Of course, this technology can only be used for photovoltaic power generation and has no effect on photothermal power generation.

The previous silicon nanophotovoltaic power generation efficiency of Snail Industry was about 29.2%. This is the efficiency after technological advancement. At the beginning, the photovoltaic efficiency was only about 28%.

In other words, the application of the opal nanostructure layer directly increases the photovoltaic power generation efficiency from 29.2% to 58.4%.

Including 12.3% of photothermal power generation, the comprehensive efficiency of solar power generation has increased to a new height of 70.7%.

Huang Xiuyuan marveled: "This is a revolutionary improvement."

"We are just standing on the shoulders of giants. Without a high-efficiency photovoltaic foundation, the effect of the opal nanostructure layer will be greatly reduced." Chen Jianxian replied modestly.

Huang Xiuyuan didn't expect that the Light Energy Research Institute would actually come up with such a powerful technology just by mentioning it.

In his future memory, there is naturally the technology related to the opal nanostructure layer, but the future opal nanostructure layer can only increase the photovoltaic power generation efficiency to about 45.7%.

Obviously Chen Jianxian's team has gone beyond the scope of the future in its research on opal nanostructure layers.

Huang Xiuyuan shook his head: "No, your technology is indeed a revolutionary progress. Does this technology currently have the conditions for low-cost mass production?"

"Chairman, we are trying, but it will take some time. The current cost of the opal nanostructure layer is still relatively high." Du Jinhua explained.

"about how much?"

Du Jinhua also showed a hint of helplessness: "The production cost of each square meter of opal nanostructure layer is about 56,000 yuan."

Hearing this price, Huang Xiuyuan also knew that it was on the high side: "This price is indeed quite high, but the aerospace field can consider it. Civilian products need to reduce costs."

"I think so too." Du Jinhua nodded.

Researchers such as Chen Jianxian also understand that this cost is too high. One square meter costs 56,000. For the civilian field where costs are limited, the cost recovery cycle will obviously be lengthened.

In the aerospace field, where costs are not considered, there is no problem.

Next, Chen Jianxian demonstrated power generation in a simulated natural environment in the laboratory. As expected, the power generation efficiency was greatly improved.

Ordinary photovoltaic panels, composite solar panels, and super composite solar panels have huge differences in the electric energy density produced by the three under the same lighting environment.

Ordinary photovoltaic panels are about 14%.

Composite panels are about 41.5%.

Super composite panels are about 70.7%.

Under the same lighting conditions, one supercomposite panel is equivalent to five ordinary photovoltaic panels. The efficiency improvement brought by opal nanostructure layer technology will further tap the potential of solar power generation for domestic power generation systems.

After watching the simulation test, Huang Xiuyuan told Du Jinhua:

"Jinhua, this technology has great potential. You must increase research and development efforts and strive to reduce production costs. As long as the cost per square meter is less than 10,000, it can be used by civilians."

Du Jinhua responded: "I understand. I will explain the situation to the Scientific Research Department and ask them to increase the research and development funding of the Light Energy Research Institute."

"By the way, if the high-efficiency version cannot reduce costs in a short period of time, you can consider lowering the efficiency. As long as it is the most cost-effective, lower efficiency is also acceptable."

"In your opinion, Chairman, we will definitely work hard." Chen Jianxian replied hurriedly.

The emergence of this technology did bring some surprises to Huang Xiuyuan, and it also proved one thing.

That is, under the current scientific research conditions, there is the possibility of transcending the future, which also proves that his large-scale investment in scientific research funds is accelerating the creation of a series of new technologies.

Maybe, the anti-neutron technology he has always been thinking about may also be developed.
