Chapter 197 Solar Power Coatings

When Zhou Yu was checking netizens' opinions on the neutrino communication network, Xiaomi suddenly appeared in front of him.

"Master, the special attention project you set up, the solar power paint project has been successfully developed."

Zhou Yu looked happy, Feng Yunde finally developed this power generation material.

The material is one of the biggest selling points of electric vehicles, and Spark Motors has been slow to release new models.

They are waiting for the three major operators to open the neutrino communication network service, which is the main reason.

The second secondary reason is to wait for the solar power paint project to be successfully developed.

This is a great gimmick and selling point, but the unmanned intelligent driving function cannot support the sales of electric vehicles.

Most of the people who are going to buy electric cars have already obtained a driver's license and become old drivers.

The function of unmanned intelligent driving is not very attractive to them, but electric vehicles consume a lot of energy, even if they are charged at night with electric waves, it is a huge expenditure every month.

What's more, some people who like to travel can put a few barrels of gasoline in the trunk when they use fuel vehicles to travel long distances.

But when they use electric vehicles to travel far, they can't always install some graphene battery packs.

Graphene battery packs need to be disassembled by professionals, which is beyond the reach of ordinary car enthusiasts. What's more, graphene battery packs are very expensive, and even local tyrants can't afford this method.

Zhou Yu immediately drove to the Materials Research Institute. He was already familiar with the laboratory that develops solar power coatings.

This laboratory is a laboratory for developing wave-absorbing materials, and solar power generation coatings are another harvest of developing wave-absorbing materials.

When Feng Yunde saw Zhou Yu coming, he showed off with a high-pressure gas cylinder: "My clever brain can only come up with such a good way, the wave-absorbing material can be sprayed on the fighter jet.

They are all the same alloy of silver iodide crystals and niobium metal crystals, and the materials used are basically the same, so why should they be made into solar panels.

Now I have successfully made solar power paint, which has more uses than solar panels. "

"Your idea is excellent, let's show the performance of solar power generation paint." Zhou Yu praised.

Zhou Yu also understands through long-term contact that Feng Yunde is an acting personality, and a few compliments when he succeeds will make him happier than giving him a bonus.

Feng Yunde took a palm-sized thin steel plate and opened the high-pressure gas cylinder in his hand.

He first sprayed a black coating on the center of the sheet steel, and then sprayed a silver-white coating on top of the black coating.

He then got two small magnets, one in the black area and one in the silvery white area, to attach it to the coating.

Put the coated side of this thin steel plate in the sun, connect the wires at both ends of the small magnet, and measure it with an electric meter.

It produces a voltage of 1 volt and a current of 1 mA.

Feng Yunde said excitedly: "Solar power generation coatings are completely different from wave-absorbing materials. You don't need to do special treatment on the sprayed materials, and you don't even need the materials to conduct electricity, so you can collect the current it generates."

Zhou Yu felt very novel, and immediately asked Feng Yunde about the similarities and differences between solar power generation coatings and wave-absorbing materials.

The two materials absorb electromagnetic waves differently.

The absorbing material is mainly used for the stealth of fighter jets. It absorbs electromagnetic waves comprehensively and tries to absorb every electromagnetic wave irradiated on the coating.

Solar power generation coatings are mainly used for power generation. It selectively absorbs electromagnetic waves with the highest energy conversion rate, mainly visible light and ultraviolet rays.

These two materials generate different voltages.

The wave-absorbing material produces high-voltage electricity, which converts electromagnetic waves quickly in a short period of time, and the voltage that generates current is very high.

What the solar power generation coating produces is the low-voltage electricity below 1 volt, and it is the energy that converts solar energy as far as possible in unit time.

Pursue the high efficiency of energy conversion, not the timeliness of energy conversion.

These two materials have different requirements for spraying materials.

The absorbing material must be sprayed on the pre-treated conductor, so that the electric energy instantaneously converted by the absorbing material can be exported in advance.

Solar power paint can be sprayed on any solid material, such as metal, plastic, and wood.

According to the concentration of the paint in the solar power generation paint, electrons flow from low concentration to high concentration.

As long as the density of the coating is changed linearly and the solar power generation coating is sprayed, a path for the current to flow will be formed.

If the coating density is determined, high magnetic electrodes are installed at specific positions at both ends of the highest concentration coating and the lowest concentration coating, so that the current can be drawn out from the coating.

Feng Yunde touched the coated steel plate with his hand, and said relaxedly: "Mr. Zhou, this is the safe solar power generation coating. The voltage and current generated are very small. It will not cause harm to the human body, even if it is touched. No problem at all.

The current only flows inside the coating, and it needs to be stimulated by a super-strong magnetic field before the current flows out of the stimulated coating.

Phenomena such as discharge will never occur, even if you drive a car with a power-generating coating to a gas station.

That will never cause a fire due to the discharge of the coating. "

Zhou Yu knew that the coating produced by this kind of solar power generation paint is very safe.

This kind of material that is often in contact with people and has a wide range of uses must be safe first.

Zhou Yu asked curiously: "I see that the electrical energy generated by this coating flows directly to the conductive material they spray, so will there be any accidents?"

Feng Yunde explained with a smile: "I'm not trying to show the function of solar power generation coating more intuitively.

When the solar power generation coating is actually applied, the coating density is not two kinds as I spray randomly.

The density of the coating will be divided into hundreds or even thousands of types to guide the flow of current in the layer.

It is not directly sprayed on the material, such as spraying on the shell of an electric car, the metal shell needs to be sprayed with an insulating protective layer first.

The conductive device is not like the two magnets I chose, it is a highly magnetic conductive needle with an extremely delicate design.

This is the channel through which the power-generating coating transmits current outward. "

After Zhou Yu listened to Feng Yunde's narration, he immediately understood the operation of the power generation coating.

Solar power paint can be sprayed on any material, but first the material must be insulated.

The insulated material is equipped with highly magnetic conductive needles that can conduct electricity from the power-generating coating.

Through this design, the power generation coating is very safe, and accidents will not occur due to discharge.

Zhou Yu was quite satisfied with the effect of the solar power generation coating. He asked: "Is the weak current generated by the coating converted by a transformer to charge the graphene battery pack?"

Feng Yunde shook his head and said: "In order to ensure safety and prevent the current from breaking through the coating and leaking out, we limit the voltage and current generated by the coating.

Such a weak voltage and current is converted into a current to charge the graphene battery pack, and a lot of energy will be wasted in this conversion process.

A breakthrough has been made in room-temperature superconductivity, and capacitors with extremely high charge reserves have been developed.

The low voltage weak current we generate from these coatings charges the capacitor.

After the capacitor is fully charged, the graphene battery pack is charged by the current discharged from the capacitor.This way energy consumption is very low. "

Zhou Yu heard that Feng Yunde adopted such an exquisite method, and he strongly praised Feng Yunde's unique ideas.
