I collect gold fingers in the heavens

Chapter 714 Sudden change

The nanopillars do not absorb light and have a different refractive index than the surrounding material, so certain wavelengths of light reflect off the array.These nanopillars can form an independent layer between the perovskite and silicon.

When light enters the cell, the perovskite layer absorbs most of the short-wavelength light, but lets some of it pass.The nanopillars are properly spaced to reflect unabsorbed light back into the perovskite layer, giving it a second chance to be absorbed.Longer-wavelength light can pass directly through the nanopillar layer without being reflected, allowing it to reach the underlying silicon.

Therefore, the solar power generation efficiency of this material is high.

The only problem is that Wu Siyuan can't make it.

This material is manufactured using nanotechnology, which Wu Siyuan has not mastered.

It's not that it can't be manufactured, and it's no problem to make it in the laboratory regardless of the cost.

However, this method cannot be widely used because the cost is too high.

Knowing this, Wu Siyuan sighed slightly.

If it can be used on a large scale, it is unlikely to completely replace fossil energy, but at least it can replace more than 50.00% of fossil energy.

Wu Siyuan can use this new energy to harvest a wave of influence.

pity.

Wu Siyuan has not yet mastered nanotechnology and cannot manufacture this nanomaterial.

There will definitely be related technologies in the future world.

However, he tried several times, and Doraemon refused to take him to the future world.

Fortunately, the other props brought back by Wu Siyuan have several technologies that Wu Siyuan can reproduce. Although they do not meet the original standards, they may be outdated technologies that will be eliminated in the future world, but in the real world, they cannot be eliminated. It is a proper international leading level.

…………………………………………………………………………………………………………………………………… ...........

Time ran away in the research of 【Transformers】scientists.

Wu Siyuan, who was immersed in it, suddenly felt that someone from the outside world was calling him.

He came back to his senses, and with a thought, his consciousness returned to Fat Tiger's body. He opened his eyes and saw that it was Doraemon, Nobita, and Xiaofu who were calling him.

"Fat Tiger, you didn't sleep here all day, did you?" Doraemon said with a speechless expression. Nobita was decadent enough, but I didn't expect Fat Tiger to go too far.

"Is it already night?" Wu Siyuan looked at the sky outside, it was indeed night.

The moon hangs in the sky, as if it is within reach.

"Hey! I really don't know what to say about you!" Doraemon shook his head and said, "It's getting dark, after playing all day, we should go back."

"Ah! I haven't written my homework yet!" Shizuka suddenly remembered this.

The little husband also showed worry when he heard this, "Me too, my mother will scold me."

"I didn't write either! My mother wouldn't scold me, but my father would beat me."

"How to do?"

"The teacher will punish you tomorrow."

The other students who had a great time playing also said worriedly when they heard this.

Nobita was very annoyed when he heard this.

I didn't expect such troublesome things.

He looked at Doraemon for help, who knew that Doraemon looked confident.

Nobita was overjoyed immediately, "Doraemon, do you have a solution?"

As soon as the words fell, Nobita's classmates all looked at Doraemon.

Except Fat Tiger, that is Wu Siyuan.

Of course Doraemon has a solution, it smiled authentically, "Don't worry, I have thought of this situation a long time ago, and I have already thought of a solution."

"Do you use [Time Machine]?" Xiaofu asked hopefully, with the most flexible head.

Other students may not understand, but Xiaofu, Fat Tiger, Shizuka and others often take adventures with Nobita and Doraemon, and I don’t know how many times I have sat in [Time Machine]!
As soon as Doraemon mentioned the solution, Xiao Fu remembered this prop.

Hearing Xiao Fu's words, Wu Siyuan also looked over.

Among all the props of Doraemon, [Time Machine] is one of the props that Wu Siyuan wants most.

If it wasn't for the fear of attracting [Time Police], Wu Siyuan would have jumped into the drawer when he was at Nobita's house, boarded the time machine, and swam in the torrent of time.

Doraemon shook his head after hearing Xiaofu's words, and said, "It's not [Time Machine]!"

Xiaofu suddenly became disappointed.

He thought for a while and asked, "Doraemon, are you going to give us the props that automatically do homework?"

"How is that possible?" Doraemon glanced at Xiao Fu angrily, "You have to do the homework assigned by the teacher yourself! This is the attitude of being responsible for yourself."

"But, Doraemon, we don't have time." Shizuka said.

"Don't worry! We have time." Doraemon said with a smile.

As it spoke, it took out the [Any Door] from the four-dimensional pocket.

Doraemon said again, "I installed [Jet Lag Adjuster] on this door."

"Just turn it..." Doraemon fiddled with the [Jet Adjuster] installed on the doorknob, and then opened the [Any Door].

[Anywhere Gate] is the country of clouds, where the night falls and the full moon hangs high.

But on the other side of 【Anywhere Door】—Nobita's house, the sun is shining brightly.

"what!"

"what!"

"what……"

Nobita's classmates all cried out in surprise.

"What's the matter?" Nobita asked suspiciously.

"I got the [Jet Adjuster] to be the time when we came to the Kingdom of Clouds. After we go back through the [Any Door], it will be daytime, so you don't have to worry about not having time to do your homework." Doraemon explained.

"what!"

"what!"

Nobita's classmates, half rejoicing, half mourning!
Doraemon didn't care about that, it said to the others, "Okay, let's go back."

After all, children still have to go home when they are tired from playing.

Nobita's classmates didn't say anything, they went through the [Any Door] one by one, and returned to Nobita's house at this time of day.

Wu Siyuan was the last one to walk into this [Any Door] equipped with a [Time Lag Adjuster].

He originally wanted to observe the [Jet Lag Adjuster] more, but there was not much time left for him.

Doraemon and Nobita kept urging on the other side.

Wu Siyuan had no choice but to walk in.

Wu Siyuan is actually not the first time to use [Any Door].

But before using [Any Door], I didn’t feel anything at all. I just stepped out and went to another place in the world.

[Any Door] is like a wormhole channel.

But this time [Arbitrary Door] was loaded with [Time Difference Adjuster], Wu Siyuan stepped in, and the whole person felt completely different.

The world is spinning.

It's changing!
In leveling for various simple dimensions.

The change is indescribable in words!

Wu Siyuan feels that one foot is in the present and one foot is in the past.

His body and soul were separated into two different dimensions.

No, not in two dimensions.

It's two positions in the long river of time.
