The limit theoretical solar conversion value of monocrystalline silicon is 30%, but this is only the limit theoretical value that scientists have reached after a lot of scientific calculations.

And this is still the limit theoretical value in the laboratory, you must know that the experimental environment in the laboratory is very harsh, not only to have very sufficient sunlight, but also to have a very good dust removal equipment and a series of harsh environments.

However, in the natural environment, such conditions can be said to be completely absent, cloudy, windy, rainy and a series of changes in the natural environment will affect the solar energy conversion efficiency of monocrystalline silicon.

For example, in the current laboratory environment, the highest solar energy conversion efficiency that scientists can achieve is only 22 percent, but if such solar panels are taken out for too much promotion, I am afraid that not too many people will be willing to pay for this kind of thing.

After all, in the harsh environment outside, the solar conversion rate that this kind of solar panel can achieve is not only 22% whitefly, but 15%, which is probably good.

In later generations, the laboratory of a scientific research institute in Japan was able to produce a solar panel that increased the solar conversion efficiency to 17% in the external environment, which was already very remarkable in the eyes of many people.

After all, compared with this kind of solar panels, which are expensive to manufacture, it is not bad to be able to achieve such a photoelectric conversion efficiency.

But even so, this kind of solar panels. There is still no large-scale promotion, and the high cost is still the main problem restricting the development of solar cells.

Now I have invested a lot of money in solar cell technology. has finally made a certain breakthrough in some aspects, how can this not make Jin Xiaoqiang happy?

After spending so much money, I was finally able to see results. This really made Jin Xiaoqiang feel a little excited.

Think about the next few years, the country has vigorously promoted the new energy economy, some local governments for the sake of political performance, so they began to swarm some monocrystalline silicon manufacturing companies and factories, not only their own investment, but also forced banks to give them loans.

The result? These are all political projects, and they have spent a lot of effort without a scientific foundation as a foundation. As a result, it can only be a downstream industry in the new energy industry chain.

A large number of solar photovoltaic factories have been launched, but the result is only the most untechnical monocrystalline silicon, with large input, low output and serious pollution, but it still can't stop the red eyes of those politicians for political achievements.

In the case of large investment, these political performance projects have been popular for a while. A large number of products at the lowest end of the solar industry chain are manufactured, and a large amount of our own energy is consumed at the expense of our environment, but the products produced are dumped at low prices like Europe and the United States. The affordable and cheap ones are all European and American countries.

Finally, as soon as the economic crisis in Europe and the United States broke out, as soon as the anti-dumping bill was introduced, our enterprises fell into a dilemma.

After all, our products have no technical content, people can use yours, or not, once you don't use it, then the last person to pay will be the enterprise itself.

As a result, what sunrise industry that was publicized at that time became a sunset industry after only a few years, and then it was exposed by the media a lot, what asset management chaos, serious environmental pollution, low technology content, a large number of duplicate construction, serious waste, without the support of the government, immediately unable to survive and a series of scandals.

A vaunted emerging industry, only three or five years old, has become a sunset industry, which really cannot but be said to be the sadness of our Celestial Empire enterprises.

Jin Xiaoqiang remembers very well that at the beginning, it was very similar to the so-called solar energy industry, and there was also the LED industry that was once boasted of being very powerful. …,

In just a few years, these companies have developed from the very beginning, to the point where they can't get along, and finally they can only be sold in tears, and they are cheapened by those upstream companies in the solar energy industry, and these upstream companies are often foreign-funded enterprises, such as Germany, the United States, and Japanese companies.

That is to say, it is equivalent to the factories that we have worked hard to build, the production lines we have bought, and the skilled workers we have trained, but in the end they have become guns in the hands of foreigners......

Every time I think of these, Jin Xiaoqiang is uncomfortable for a while, when will our Celestial Empire's enterprises be able to compete a little bit?

In fact, we all know that the most difficult and bitter thing to do technology is to increase investment in scientific research, but because of some political factors, everyone has become very happy, only care about the little interests in front of them, and have not considered the long-term development plan at all, which is our greatest sorrow.

So in this life, Jin Xiaoqiang feels that if he has the ability, then he must get a kick in this field, not only to fight for our Celestial Solar Energy Enterprise, but more importantly, he is really optimistic about the future prospects of this industry.

"It can also be said that a certain breakthrough has been made, but this breakthrough, we don't think it's particularly thorough, but after discussing it with Edwards, we still decided to report to you first."

Matt has been in the Celestial Empire for a year, but he has learned the habit of talking and liking Tai Chi in the Celestial Empire very smoothly.

"Hehe, okay, you can tell me about your scientific research achievements in the past year."

Jin Xiaoqiang said with a smile, looking at the smug expressions of these two people, he knew that these two people must have made a certain breakthrough in the field of solar panels.

These scientists are not all self-explanatory, they also need recognition and recognition, especially in the eyes of those who they see as important.

At this time, one of their own concerned demeanor often makes them feel very moved, so Jin Xiaoqiang's expression at this time is very serious.

Matt and Edwards became more and more happy when they saw the attitude of the big boss and such seriousness.

Matt took out a USB flash drive, and Edwards took out the laptop they had brought with them, and walked to the demo hall of Jin Xiaoqiang's office.

Jin Xiaoqiang's office is very large, and there is a computer demonstration hall specially prepared for the scientific researchers below when they report to him, and there are projection equipment in it.

The two quickly connected to the computer equipment, and soon the projection screen on the wall showed their recent scientific work.

"Monocrystalline silicon solar cells, which is one of the traditional solar cell technologies, we have been working in this field long before we worked with you, and we have been working on it for more than ten years. However, because of the relationship between materials, we have not been able to make any breakthroughs, but in this study, Edwards and I have also perfected the theory of our solar turbocharging technology, which is to use the change of the atomic arrangement and structure of monocrystalline silicon to achieve a more efficient capture of red photons, and convert them into yellow photons with greater energy, and then carry out photoelectric conversion. ”

Matt reviewed their theory to Jin Xiaoqiang again, and Jin Xiaoqiang nodded after listening to it, it was precisely because he realized the feasibility of their theory that he invested in their solar energy research project, and it seems that this is a good deal.

"It wasn't until a year ago, through the new material of monocrystalline silicon that you provided by you, that we were finally able to refine our solar turbocharging theory, and with this new model of solar absorbing material, we only made some solar panels. And this new type of panel has really improved the photoelectric conversion efficiency. Japan's Aichi Laboratory announced last year that the photoelectric conversion efficiency of their newly developed solar cells is 22 percent, of course, this is the theoretical extreme value of the laboratory, and in the outside natural environment, the natural conversion efficiency of their solar panels is only 17 percent, which is still in the best case. And that's just the case with the U.S. side. But this year, Edwards and I have obtained the highest conversion extreme value of our solar cell through experiments, and the conversion efficiency of our solar panel can reach up to 28.5% in the laboratory environment, which is very close to the theoretical conversion extreme. In the external natural environment, the highest conversion efficiency of our battery can reach 22%, and the average conversion efficiency can reach 20%. ”

Seeing Jin Xiaoqiang constantly nodding his head in affirmation, Matt here is eyebrows are dancing and foaming at the mouth, this new solar cell has obviously been affirmed by the boss.

Jin Xiaoqiang was very satisfied with Matt's demonstration and explanation, he knew that the theoretical photoelectric conversion extreme value of monocrystalline silicon was only 30 percent, and Matt and Edwards were now able to make their solar cells achieve an efficiency of 28.5 percent in the photoelectric conversion rate, which would have caused an uproar in the scientific community if it was announced.

At 28.5 percent, that's far behind the data from Aichi Laboratories in Japan, which is completely unthinkable for many scientists.

"Of course, according to my calculations and Edwards' calculations, this is not the limit of our research theory, we have made a lot of speculations in more than a year according to the photoelectric conversion efficiency of this solar cell, and we have made calculations on our solar pressurization theory again according to experiments and actual conditions, and redesigned the array of monocrystalline silicon yard arrangement......"RQ
