This civilization is very strong, but the technology tree is a bit crooked

Chapter 45 846% of the day does not set the drone!

Chapter 45 84.6% of the day does not set the drone!

Come to the second floor.

Chen Yi turned on the computer and found the previous design drawings of the drone.

Connect a 3D printer and reprint a batch of drone accessories.

The ion propulsion UAV that was tested before, because the properties of the battery have been adjusted, the radar shooting module and communication module equipped are also the product of multiple superimpositions.

Now add solar panels, add external function modules.

The quantum field of the item will collapse and reorganize again, and subsequent information cannot be read.

If you want to make further improvements and read technical information, you can only recreate a new drone with material accessories that have not been adjusted and superimposed.

Watch for a while to make sure the 3D print is working properly.

Chen Yi took the previous drone, connected it to the computer, and exported the test flight data of the last black eagle hunt.

Data is automatically exported.

Chen Yi went over to turn on the battery production equipment and re-produced a batch of batteries.

After several hours.

New drone accessories, engine modules, and batteries are all produced.

Chen Yi picked up the spare parts that were still warm, quickly completed the assembly of the drone, and imported the manually written avionics control program.

Then, put the pure original, without adjusting the attributes.

The theoretical safety attribute is 10, but the actual safety attribute is only 1.4. The battery is carefully installed in series.

"Huh, it didn't explode, it seems my technology is better than Samsung Note 7."

Seeing that the battery was successfully installed, the expected smoke, fire and explosion did not happen.

Chen Yi breathed a sigh of relief, took the solar panel next to it, and connected it to the charging terminal of the battery after being boosted and rectified.

[Item: Ion Propulsion Drone]

[Attributes: Energy x42.1 (!), Speed x1.6, Quality x21, Stability x2.6, Strength x14, Communication x12.5, Radar Shooting x10.6, Avionics x34.5, Beauty x3.8, Endurance Supplement x4.6]

[Wave of Consciousness: 6801203]

[Note: This is a uniquely designed ion-propelled aircraft, but unfortunately, the unsafe and stable energy core makes it full of dangers and cumbersome battery life supplementary modules, resulting in a straight drop in stability, speed, and beauty, making it impossible to fly normally . 】

"I didn't expect this explosive battery to even come out with a warning exclamation mark."

Chen Yi took a few steps back, making sure to stand at the safest distance possible to adjust attributes.

call!

Colorful rays of light bloom.

The drone with the solar panels on its back enveloped Chen Yi.

The properties of solar panels are being adjusted rapidly, and the shape and form are constantly changing.

Ten seconds later, the light dissipated.

The original thick, hard, square monocrystalline silicon solar panels disappeared.

In its place is a special black translucent film.

On the film, there are faint golden threads spreading, forming small nodes like slime mold, and finally converged into two wires, which are connected to the charging port of the drone.

"It's a bit like the thin film circuit board in the previous thin film keyboard."

Chen Yi looked at the brand new solar circuit board and checked the attributes of the drone.

[Item: Ion Propulsion Drone]

[Attributes: Energy x21.1 (!), Speed x2.6, Quality x21, Stability x2.6, Strength x14, Communication x12.5, Radar Shooting x10.6, Avionics x34.5, Beauty x4.8, Endurance Supplement x24.6]

[Wave of Consciousness: 6790203]

[Detecting that a certain attribute exceeds the initial value, do you want to read the information? whether! 】

[Note: This is a unique ion-propelled aircraft, but unfortunately, the unsafe and stable energy core makes it full of danger.

The thin and light endurance supplementary module also reduces its stability, speed, and aesthetics.

Perhaps, you can find a way to attach the film to the surface of the fuselage, which may bring you some surprises. 】

"The solar panel becomes a solar cell film, which improves the appearance a little bit."

"The idea of attaching the battery membrane to the surface of the fuselage is exactly what I want. It seems that the system still understands me."

"But it's a pity that it's just a simple fit, which can't withstand too high a speed."

Chen Yi looked at the comments in the notes, and was not in a hurry to read the information.

Instead, take out a monocrystalline silicon solar panel, connect it to a high-precision current and power measuring instrument, and put it under the sun on the balcony.

Then, connect the solar cell film together with the current and power measuring instrument.

Spread it out together with the monocrystalline silicon battery panel, put it on the balcony, and enjoy the sunlight.

Five minutes later.

Chen Yi recorded the power values of a single solar panel and solar cell film, and then measured the areas of the two, and finally obtained the solar energy conversion efficiency of the two.

"After calculation, the standard unit area.

The ten-minute average power of the cell membrane is 42 watts, and the ten-minute power of the monocrystalline silicon solar panel is 21 watts.

According to most monocrystalline silicon solar panels, the actual solar energy conversion rate is 18 percent.

The solar conversion rate of this battery film has reached 35.9 percent.”

Looking at the calculated value, Chen Yi shook his head in disappointment.

35.9 percent solar conversion rate.

It is still far from the standard he requires.

As far as he knows, as early as two years ago.

NREL researchers at Eagle Sauce, which use II-V compound materials, have developed solar panels with nearly 50 percent conversion efficiency in the laboratory.

"Read the message."

Numerous information emerged in Chen Yi's mind.

Compared with the previous complex material structure or dense algorithm.

This time the message is simpler.

It is a kind of thin-film semiconductor material with a light-gathering structure prepared by chemical deposition, and there are corresponding slicing, series connection, splicing, lamination, compound packaging and other processes.

The process is very common, and any solar panel manufacturer can do it.

The real essence is this special semiconductor material.

Common polycrystalline silicon or monocrystalline silicon solar panels.

This is through the photoelectric effect of semiconductors, which converts light energy into electrical energy.

But because the reflectivity of the single crystal silicon material itself is too high, a considerable part of the energy is reflected.

In some giant solar photovoltaic bases, the light reflection is too dense, and sometimes birds can be fainted when they fly by.

And now this unique thin film semiconductor compound material is through a special microstructure.

Like a magnifying glass.

Gather the light irradiated by the outside world, reduce reflection, and increase the conversion intensity and efficiency of light.

"It appears to increase the light-gathering effect of the material and reduce reflections."

"This should be the direction of technological breakthroughs for the next generation of solar panels."

Chen Yi guessed in his heart and continued to adjust his attributes.

【Energy: 21.1→7.1】

[Avionics: 34.5→24.5]

【Supplementary battery life: 24.6→44.6】

【Stable: 2.6→4.6】

【Speed: 2.6→4.6】

[Detecting that a certain attribute exceeds the initial value, do you want to read the information? whether! 】

The light dissipated, and what appeared in front of Chen Yi was a thin and translucent plate.

The original solar cell film hardens, becomes stronger, and becomes firm again.

Connected to a high-precision power meter, Chen Yi conducted a comparison test with monocrystalline silicon solar panels as usual.

"Average 64 watts in ten minutes, the conversion rate is 54.8%. Read the information."

After some tests and calculations, Chen Yi obtained the conversion efficiency of the solar panels.

Without hesitation, directly choose to read the information.

"Group II-V, gallium nitride compound materials.

It also has a light-gathering structure to reduce the reflection of light.

At the same time, the photoelectric effect is more obvious, which reduces the internal resistance of the solar panel.

The heat dissipation effect is also better, which reduces the loss caused by the increase in resistance due to the increase in irradiation temperature during the day. "

Chen Yi Shenwu digested the information in his mind.

After a long time, I suddenly realized, and guessed: "If I'm not wrong, this should be the solar panel developed by the researchers of Yingjiang NREL Institute, using II-V compound materials in the laboratory.

And it is still more perfect, realizing industrial mass production, advanced version of technology.

It seems that I have time to sort out the technical details.

While the technology of Eagle Sauce is still in the laboratory stage, before realizing industrial mass production, a wave of global patents has been registered.

Peaches, or pick other people's incense! "

Chen Yi put this matter on the agenda, looked at the drone in front of him, and continued to adjust the attributes.

[Avionics: 24.5→7.5]

【Supplementary battery life: 44.6→69.6】

【Stable: 4.6→7.6】

【Speed: 4.6→7.6】

【Communication: 12.5→7.5】

[Quality: 21→9]

Colorful lights emerged.

The attributes of drones are being adjusted rapidly.

When the light dissipated, the original hard and strong gallium nitride solar panel has changed.

It becomes a kind of hazy distortion, but the color is like black crystal in a mirage, and the whole is filled with soft, thin solar cell film.

"It's the limit."

Chen Yi looked at the attributes that could no longer be adjusted after the battery life was added to 69.6.

I knew in my heart that this should be the limit of the solar panel.

Although the photoelectric effect, which is a physical phenomenon at the atomic level, can achieve energy conversion efficiency far exceeding chemical energy.

For example, the electromagnetic force effect of the motor can easily achieve an energy conversion rate of more than 90%.

However, compared with the sealed environment of the motor, the solar panel is affected by the external environment, and the efficiency will definitely be much worse.

As for 100%...

Thermodynamic limitations.

No matter how awesome the motors and solar panels are, it's impossible to achieve 100%.

"Test it and see if it breaks through 80 percent."

Chen Yi connected a power measuring instrument to the battery membrane, and hurriedly tested it before the sun set.

After ten minutes of testing, the value came out.

"Ten minutes average 98.7 watts, 84.6 percent hiss!"

Looking at the conversion rate value from the test, Chen Yi couldn't help taking a breath.

Conversion value beyond imagination!

It can convert 84.6 percent of solar energy into electricity.

"With this solar cell film."

An astonishing idea flashed in Chen Yi's mind: "It seems that I can design a real drone that the sun never sets based on this solar cell film."
