Matt and Edwards have been interested in how to improve the efficiency of solar energy conversion since they were researching solar technology for a long time.
In fact, the efficiency of solar energy conversion has always been the biggest problem plaguing the entire field of solar energy scientific research.
In the earliest days, the materials used by people in solar cells were some special coatings, which absorbed the heat energy of the sun, and then converted this heat energy into kinetic energy.
Later, there are scientists who convert this thermal energy into chemical energy, then store it, and then convert it into kinetic energy.
For more than 100 years, human scientists have done a lot of research on the research and transformation of solar energy, and have used various means to achieve their goals.
It was not until the fifties and sixties of the last century, with the new breakthroughs made in chemical science and physical science, that human scientific research on solar energy became truly realistic.
Especially with the breakthroughs in the field of batteries and breakthroughs in the field of materials science, human scientists have made greater progress in the field of solar energy conversion.
Since the seventies and eighties of the last century, human scientists have been trying to use silicon wafers as materials for a new generation of solar converters.
Because silicon wafers belong to semiconductor materials, their own conductivity is not particularly good, but it has a unique advantage in absorbing solar energy, then storing it, and in terms of numerical control management.
Therefore, in recent decades, silicon wafers have become more and more an important part of solar energy conversion technology and means, and it has been made into solar photovoltaics in large quantities for research in this area.
However, although silicon wafers are increasingly made into photovoltaic materials for various solar energy conversions, they have not improved the current solar energy conversion rate much in terms of solar energy conversion efficiency.
At present, the general conversion rate of solar converters made by human beings, even with the best silicon wafers as photovoltaics, is controlled between 19% and 22%.
It is quite difficult to get higher.
Matt and Edwards also discovered this problem, so they analyzed the silicon wafers used in solar panels from various angles, and various methods emerged one after another.
After several tests, they finally found that the reason why the silicon wafers used today have not been able to achieve higher solar energy conversion is mainly related to the internal physical and molecular structure of the silicon wafers currently used.
The molecular structure of the silicon wafer currently used determines that they cannot quickly catch the yellow photons in the solar pipeline, but only the red photons.
The energy carried by the red photon is significantly smaller than that carried by the yellow photon.
Generally speaking, it takes two or more red photons to be able to match the energy of one yellow photon.
So how can silicon wafers catch more yellow photons instead of red photons?
Or how can the red photons caught by the silicon wafer be more effectively converted into more energetic yellow photons?
Therefore, the two scientists did countless simulation experiments on the computer and finally came to the conclusion that if the silicon wafer is to become more efficient in the solar energy conversion problem, and can more quickly and effectively catch the yellow photons with greater energy in the solar energy, then the physical molecular structure of the silicon wafer must be adjusted.
Let each silicon crystal molecule be arranged at an angle of 60 degrees, so that the three silicon crystal molecules can form a solid equilateral triangle, so that when the sunlight hits the silicon wafer, a solid triangle layout made by each three silicon crystal molecules can quickly catch the sun's rays, and the yellow photon with the most sufficient energy will not directly break through the stable triangle and consume the energy because the energy is too large. …,
In this way, when the yellow photon hits the stable triangle, the energy it carries will quickly impact the equilateral triangle, and then cause the peripheral electrons of the silicon crystal molecule itself to overflow, and then through effective guidance, these electrons will be introduced into a battery for storage.
Or directly input the electrical energy formed by these electrons to the power grid, or directly use it for heating, or convert it into kinetic energy, etc., so as to achieve the purpose of improving the solar energy conversion rate
Moreover, the equilateral triangular arrangement structure of such silicon crystal molecules can also quickly convert the weaker red photons caught into yellow photons when the light is insufficient, because when two or more red photons hit the equilateral triangular structure composed of a silicon wafer, because the energy is weak, they cannot break through the equilateral triangular structure of the silicon wafer, and they will quickly combine into a yellow 'sub because of the vibration of the same spectrum. In this way, the energy is quickly converted to the electron movement of the silicon wafer.
In this way, the efficiency of photoelectric conversion can be greatly improved.
After rough calculations, if such a silicon wafer can be made, then after using this kind of silicon wafer as a solar photovoltaic, the photoelectric conversion efficiency of solar energy will be at least doubled compared with now!
What is this concept, but it means that the conversion efficiency of this new solar panel will be increased to between 38 and 44 percent.
If you use such a silicon wafer and make a thin-film solar cell like the kind that Matt and Edwards just developed, if you glue such a thin-film solar cell to the roof of a car.
Then a hybrid car with such a sock-filled battery, in battery-powered mode, his range will most likely exceed eighty or even a hundred kilometers, of course, and this is in very good sunlight.
Don't underestimate these 80 to 100 kilometers, for now, the best hybrid car in the world is Toyota's Prius, but the battery life of the current Prius is only more than 20 kilometers.
Later, the endurance of a hybrid car launched by BYD was reported to be more than 50 kilometers at the time, and this data was already very amazing as soon as it came out.
And if such solar cells are used, coupled with more and more mature lithium batteries, and kinetic energy recovery systems, then as long as Jin Xiaoqiang can make the battery life of their hybrid vehicles reach or even exceed 80 kilometers, it will definitely be a milestone.
And such a model, the fuel consumption, must be amazing, even in a congested city, the estimated fuel consumption per 100 kilometers, is only a few thousand.
However, please note that the fuel consumption of 5.00 points per 100 kilometers is purely urban congestion.
Don't look at the current Captain America fuel consumption of Huayang Power's 100 kilometers is five liters, which is comparable to Toyota's Prius, but you must know such fuel consumption, but after running a section of the highway, and then after running a section of the congested road in the city, the comprehensive fuel consumption is obtained.
And this has to be through professional drivers, to be able to run out of the data, if you change to ordinary people, want to run out of such data, it is almost impossible.
If ordinary consumers get their hands on such a car, then the fuel consumption of 100 kilometers they personally drive down will definitely not be lower than six points.
Therefore, the comprehensive fuel consumption of 100 kilometers announced by general automobiles is not so accurate, which is the unspoken rule that Quanta automobile manufacturers and consumers have reached a consensus. …,
Consumers will not compete with car manufacturers too much on these issues, generally according to the fuel consumption of 100 kilometers announced by the car manufacturer, and then float up one liter or a few liters of fuel consumption, which is the real fuel consumption of this car 100 kilometers, which has become common sense recognized by everyone.
Therefore, if a hybrid car using such a solar cell can really run a real fuel consumption of 5.0 liters per 100 kilometers in the city, then the data performance of this car is undoubtedly very amazing.
When the time comes, in the big era of hybridization, this car will definitely be a very amazing product.
But the premise is that this kind of solar cell must be developed before the era of hybrid vehicles.
The key to this is how to change the internal molecular arrangement of the silicon wafers that are used as solar photovoltaics.
If it was before, Jin Xiaoqiang would definitely have no way to speak of, he knew nothing about solar energy, and he didn't know anything about the manufacture of silicon wafers.
But now it was different, especially after he learned that the nanomolecular cells in his hands were best at changing the molecular arrangement and structure of other substances, and then highlighting the characteristics of a certain aspect of this substance.
Imagine that in the future, when the silicon wafer is manufactured, especially in the raw materials of the silicon crystal, when the fine sand is cleaned, screened, and then sent to the silicon crystal cultivation and growth furnace, I secretly sprinkle a certain proportion of nano biological cells that have obtained my own instructions among the raw materials, and then the silicon wafers refined by the culture furnace have the characteristics of appeal.
As soon as he thought of this, Jin Xiaoqiang felt a little impatient, and what he most desperately wanted to see now was that the solar energy research institute was established as soon as possible, and then he could verify his inference
