Traveling through the 60s, an interstellar woman makes a fortune by selling men

"How can we ensure the stable endurance of the combat helicopter in the event that the converted electric energy is used up?" Meng Xianying was very worried. This leader who was afraid of chaos in the world also expressed that he would personally test it. What if the helicopter crashes?

The most important thing is that it is rare to have a person in charge who is so easy to talk to. If he loses his temper, who will they sign for the project? There will never be a superior who is so easy to talk to.

You know, in just a few days, all the nuclear submarines, aircraft carriers, lithography machines, and computer projects they applied for were approved. It went so well that he was afraid that this person would be blamed for it.

"I usually store more energy. I plan to use solar cells to store more electricity so that I won't be blinded at critical moments." Wei Wei explained, who dares to go directly to the sky without enough electricity to rely on the sun.

"Also, two systems can exist at the same time. When solar energy technology is not yet mature, if an emergency occurs, you can emergency brake and change to the fuel system, leaving yourself a way out. This is not difficult."

Her original intention was just to save some engine oil for herself...

Wei Wei has already thought about it. She doesn't want to become a fat person without taking one bite. The basics are here. She doesn't have the ability to reach the sky in one step.

She just wasn't willing to give up another good job, so she needed to have this combat helicopter that could allow her to do both.

The biggest problem now is the proportion of solar energy converted into energy.

Although the development and utilization of solar energy on the Origin Star is still on the shallow surface, Interstellar has become particularly mature. She once set up a machine in the valley using materials brought by Interstellar to build her own private laboratory.

"The first thing we have to deal with is the storage and conversion of solar energy. In my idea, the conversion center is located in the solar cell." Wei Wei stated his thoughts simply and straightforwardly.

"Have you heard of the photovoltaic effect?" Wei Wei asked.

Meng Xianying nodded, "I know a little bit about it. It can directly convert light energy into electrical energy."

Wei Wei: "We all understand the basic principles. What is important now is the selection of materials. Different materials have different conversion utilization rates."

"Then what materials do you want to use?" Meng Xianying asked, "Also, you have approved several projects. Do you want to see the funds first? After reading the funds in the account, we can decide on the materials. Our funds are very tight. There is no money. If it’s too much, you often have to repay it.”

Wei Wei turned around in surprise, "Oh, didn't I tell you? The consumables for transforming this combat helicopter were funded by me personally. After all, the helicopter is my own, so how can I spend the country's money?"

Wei Wei makes a clear distinction between public and private affairs. If public tools are used privately, doesn't it become corruption?

"Okay, that's no problem." Meng Xianying calmed down. He believed that a family that could cultivate outstanding figures like Wei Wei would not be unable to afford a project.

"Now let's discuss semiconductor materials." Wei Wei circled several alternative materials, including photovoltaic-grade monocrystalline silicon and perovskite. He noticed that the eyes of several slightly younger researchers next to him were confused, so he decided to explain in depth.

"Here, let me explain it to everyone," Wei Wei pulled out a piece of white paper and drew the whole process.

"...In the whole process, non-equilibrium carrier distribution generates a photogenerated electric field. The direction of the electric field is opposite to the direction of electron transition. Electrons flow from the conduction band to the valence band, and holes flow from the valence band to the conduction band. This is the basic principle of converting light energy into electrical energy. .”

"The semiconductor on the surface of the designed solar cell absorbs light energy, generates an electric field to form an electromotive force, and supplies power to the helicopter through wires and electric loads."

"In addition, I designed this flower pattern based on a sunflower. Each petal is a solar cell, which can track the direction of the sun and constantly adjust the angle to ensure direct sunlight. This can increase the power generation by 45%; If possible, I would also like to install automatic water jets behind each semiconductor petal, which can actively clean the dust on the surface and better absorb light energy."

Wei Wei paused for a moment, paying attention to the eyes of the researcher listening to the lecture to see if he understood.

"So, how do you get the monocrystalline silicon you chose? We can't make it." Meng Xianying is worried. We have theoretical support, but we don't have the machinery to produce it. We are blind.

"It's okay, let's take it step by step. First, do we have the machinery to obtain and polish the silicon rods? Do we have a cutting machine after obtaining the silicon rods?"

Meng Xianying nodded first, then shook her head, "There are cutting machines. There is a semi-stopped computer laboratory at Lao Guo's place. In order to achieve a breakthrough in chips, there was this machine, but it was broken and could not be repaired."

"But we can't obtain silicon ourselves. It requires putting silicon-rich sand and carbon into a clamp furnace for smelting at the same time. We can't extract silicon with a purity of 99% through this process. We can't even smelt steel. If you are immature, what can you use to extract silicon?" Meng Xianying seemed to be following Wei Wei, just to pour cold water on him.

"There was an electric arc furnace recently, which changed the situation. How about I go to the military factory below to borrow an electric arc furnace and try to extract it?"

"What I need is higher ultrapure silicon, otherwise the conversion efficiency will be too low." Wei Wei said weakly, "By the way, do we have slender single crystal silicon with more than 99%?"

She needs 99% silicon as a guide to deposit silicon atoms on the surface of single crystal silicon, and slowly pulls it upward to obtain a single crystal ingot with a purity of 99.999%. Only by obtaining it can she have the material for the cutting machine to cut into thin slices...

"Yes, there are only a few, so we have to use them sparingly." Mr. Meng said that they were poor and couldn't spend too much money.

"It's okay. The extraction of the single crystal ingot is all on me. Besides, your lithography machines and computers also need it. Come on, let's find a way." Wei Wei is very confident in herself, and improvement is her specialty.

Although Mr. Guo opened the laboratory to Wei Wei and the others, he followed Wei Wei closely, fearing that Wei Wei would damage his instruments.

Wei Wei not only saw the cutting machine, but also two familiar pieces of equipment, a photolithography machine and a CNC grinder...

Having had a transformation experience, Wei Wei followed the same method. Moreover, this time he did not use old machines to transform, but borrowed from a subordinate military factory to rebuild it from beginning to end, and built a clamp furnace.

Soon, new instruments were released, but the photovoltaic-grade monocrystalline silicon in Wei Wei's imagination was directly upgraded to semiconductor-grade monocrystalline silicon...

After Wei Wei thought for a while, he knew what the problem was. After all, the instruments in the valley were old machines or abandoned machines, which were not as good as newly built instruments.

When Mr. Guo took over the semiconductor-grade monocrystalline silicon produced by his family, his hands trembled. With it, half of the chips they needed were obtained.

The other half, he believed that Wei Wei, this crape myrtle star descending from the sky, would definitely allow them to have their own chips.

Wei Wei's eyelids twitched. He accidentally applied too much force and turned the photovoltaic grade monocrystalline silicon into semiconductor grade monocrystalline silicon.

Now if she says that she wants to lower the parameters of the instrument, Mr. Guo and Mr. Dong are afraid that they will fall out and forget their old relationship...
