Come to the second floor.

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

Connect to a 3D printer and reprint a wave of drone accessories.

The ion-propelled UAV that was tested before, because the properties of the battery have been adjusted, the radar shooting module and communication module equipped with it are also superimposed many times.

Now add solar panels, add external function modules.

The quantum realm of the item will collapse and reorganize again, and it will be impossible to read the subsequent information.

If you want to make further improvements, read the technical information, the only way to do this is to recreate a new drone using material accessories that have not been adjusted for superposition.

Observe for a while to make sure that the 3D printing 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.

The data is being exported automatically.

Chen Yi turned on the battery production equipment and re-produced a batch of batteries.

Hours passed.

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

Chen Yi picked up the accessories that still had residual temperature, quickly completed the assembly of the drone, and imported the avionics control program that had been manually written.

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

The battery with a theoretical safety attribute of 10, but an actual safety attribute of only 1.4, is carefully connected in parallel and installed.

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

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

Chen Yi breathed a sigh of relief in his heart, took the solar panel next to him, and after supercharging and rectification, he connected it to the charging end of the battery.

[Item: Ion Propulsion Drone]

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

[Consciousness Wave: 7620203]

[Note: This is a unique ion propulsion aircraft, but unfortunately, the unsafe and stable energy core makes it full of dangers, cumbersome endurance supplement modules, resulting in a plummeting of stability, speed, aesthetics, etc., and it is impossible to fly normally.] 】

"I didn't expect this explosive battery to even come out with an exclamation point of warning."

Chen Yi took a few steps back, making sure to stand at the maximum safe distance where he could adjust his attributes.

Call!

Colorful light blooms.

Shrouded the drone with solar panels on its back in front of Chen Yi.

The properties of solar panels are rapidly changing, and their shape and form are constantly changing.

After a dozen seconds, the light dissipated.

Gone, the heavy, hard, square monocrystalline silicon solar panels are gone.

Instead, a special black translucent film is used.

On the top of the film, there are faint gold wires spreading, forming small nodes like slime molds, and finally converge into two wires, which are connected to the charging port of the drone.

"It's kind of like the membrane circuit board inside the old membrane keyboard."

Chen Yi took a look at the brand-new solar circuit board to check the properties of the drone.

[Item: Ion Propulsion Drone]

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

[Consciousness Wave: 7618203]

[If you detect that a property exceeds the initial value, do you want to read the information?] Yes/No! 】

[Note: This is a one-of-a-kind ion-propelled vehicle, but unfortunately, the unsafe and stable energy core makes it full of dangers.]

The thin and light battery life supplement 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 panels have become solar cell films, and the aesthetics have been improved a little bit."

"The idea of attaching the battery film plate to the surface of the fuselage is exactly what I want, and it seems that the system still understands me."

"But unfortunately, it's just a simple fit, which can't withstand too high speeds."

Chen Yi looked at the comments and didn't rush to read the information.

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

Next, the solar cell film is connected to a current and power meter.

Spread out along with the monocrystalline silicon panels and place them on the balcony to enjoy the sunlight.

Five minutes later.

Chen Yi wrote down the power values of a single solar panel and a solar cell film, and then measured the area of the two, and finally obtained the solar conversion efficiency of the two.

"After calculation, the standard unit area.

The average power of the battery film for 10 minutes is 42 watts, and the power of the monocrystalline silicon panel for 10 minutes is 21 watts.

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

The solar energy conversion rate of this cell film has reached 35.9 percent."

Looking at the calculated values, Chen Yi shook his head with some disappointment.

35.9 percent solar energy conversion rate.

It's still far from the standard he demanded.

As far as he understands, back two years ago.

Eagle Sauce's NREL researchers, using II-V compound materials, have developed solar panels in the lab with a conversion rate of nearly 50 percent.

"Read the information."

Dense information surfaced in Chen Yi's mind.

Compared to the previous complex material structure or dense algorithms.

This time, the information is relatively simple.

It is a thin film semiconductor material with a concentrating structure obtained by chemical deposition method, and there are corresponding processes such as slicing, serialization, splicing, superimposition, and chemical packaging.

The process is very ordinary, and it can be completed by any solar panel manufacturing factory.

The real essence is this special semiconductor material.

Common polycrystalline silicon or monocrystalline silicon solar panels.

This is done by converting light energy into electrical energy through the photoelectric effect of semiconductors.

However, because the reflectivity of the monocrystalline silicon material itself is too high, a considerable part of the energy is reflected out.

Some giant solar photovoltaic bases reflect so much light that birds can sometimes be stunned when they fly by.

Now, this unique thin-film semiconductor compound material is made through a special microstructure.

Like a magnifying glass.

The light irradiated from the outside is concentrated to reduce reflection and increase the intensity and efficiency of light conversion.

"It seems to improve the light-concentrating effect of the material and reduce reflections."

"This should be the technological breakthrough direction of 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]

[Endurance supplement: 24.6→44.6]

[Stable: 2.6→4.6]

[Speed: 2.6→4.6]

[If you detect that a property exceeds the initial value, do you want to read the information?] Yes/No! 】

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

The original thin film of the solar cell has become stiffer, stronger, and stronger again.

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

"The 10-minute average is 64 watts, and the conversion rate is 48.8 percent...... Read the information and take a look. ”

After some testing and calculation, Chen Yi came up with the conversion efficiency of the solar panels.

Without hesitation, choose to read the information directly.

"Group II-V, gallium nitride compound materials.

It also has the microstructure of concentrating light, while reducing the resistance inside 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, it suddenly dawned on me and guessed: "If I guessed correctly, this should be the solar panel developed by researchers from the Eagle Sauce NREL Institute using II-V compound materials in the laboratory."

Moreover, it is more perfect, realizing industrial mass production, and the advanced version of the technology.

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

While Eagle Sauce's technology is still in the laboratory stage, a wave of global patents has been registered before it is industrially mass-produced.

Peaches, or pick someone else'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]

[Endurance supplement: 44.6→69.6]

[Stable: 4.6→7.6]

[Speed: 4.6→7.6]

[Communication: 12.5→7.5]

[Mass: 21→9]

......

Colorful light emerges.

The drone's properties are being adjusted at a rapid pace.

When the light faded, the original hard, stiff GaN solar panels had changed their appearance.

It became a hazy and deep, black crystal like a mirage, but filled with soft, thin solar cell films.

"It's the limit."

Chen Yi looked at the attributes that the battery life could no longer adjust when it was replenished to 69.6.

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

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

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

However, compared with the sealing environment of the motor, the efficiency of the solar panel will be much worse due to the influence of the external environment.

As for 100 percent......

Thermodynamic limitations.

No matter how awesome the motors and solar panels, this cannot be 100 percent.

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

Chen Yi connected the power measuring instrument to the battery membrane, and took advantage of the sun before it set, and hurried to test it.

After ten minutes of testing, the values came out.

"The 10-minute average is 98.7 watts, 84.6 percent...... Hiss! ”

Looking at the conversion rate value of the test, Chen Yi couldn't help but take a breath.

Conversion values beyond imagination!

84.6 percent of solar energy can be converted into electricity......

"With this solar cell film."

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

"If the sun doesn't set, I won't set!"
