"What the hell does that mean?" Luo Hao exclaimed, "No wonder it can only be charged with light energy?"

At present, there are two main ways of solar power generation researched in the world:

One is: light-heat-dynamic-electric conversion method, heat energy is generated through light energy, and then heat energy is used to make water generate water vapor, and the rising force of water vapor drives the steam turbine to rotate to generate mechanical energy, and finally converts from mechanical energy into electrical energy.

The other is: light - electricity direct conversion.The principle is to use the photoelectric effect to directly convert solar radiation into electrical energy. The basic device for photoelectric conversion is a solar cell.A solar cell is a device that converts sunlight energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode will convert the sun's light energy into electrical energy, generating current.When many batteries are connected in series or in parallel, it can become a solar cell square array with relatively large output power.

And the material that Luo Hao got in his hand was a kind of photoelectric cell material, and photoelectric cells happened to belong to the category of physics.

At present, the photovoltaic cells on the market are large in size and low in conversion rate. Although they are environmentally friendly and can continuously provide electricity, their efficiency is too low and they cannot meet the purpose of household or even portable use—unless the electrical appliances themselves consume electricity Very low. For example, the shared bicycle that Luo Hao usually rides by scanning the QR code has a solar panel in the basket. That is because there is a battery in the lock of the shared bicycle. It is used to charge the battery in the lock, and it cannot store electric energy itself.

Luo Hao occasionally rides a shared electric car, and has never found a solar panel in the basket. That is because the shared electric car itself needs to be charged regularly, and a small solar panel cannot provide such a high voltage and current.

However, the information in Luo Hao's hand perfectly solved this problem, which made Luo Hao gradually immersed in it.

Time passed minute by minute, and Luo Hao stayed in the laboratory for another whole day in a blink of an eye.

This day, Luo Hao didn't do anything, he was just simply researching the materials. By the way, he called Wei Chang'an and asked him to help prepare some materials.

Looking at the list of materials sent by Luo Hao, Wei Changan felt a little strange: Why are there all semiconductor materials in the list of materials this time?But he didn't think too much, and agreed happily.

This saved Luo Hao a lot of tongue, he didn't want too many people to know what he was researching for the time being.

After 7 o'clock in the evening, Luo Hao finally finished reading the information on the computer and stretched himself.After putting away the USB flash drive, he put on his coat and went home.

"Didn't eat?"

As soon as Luo Hao entered, Luo Mu asked.

"Hey, Mom, how do you know?" Luo Hao was taken aback for a moment, then he laughed.

"You don't look like you have eaten. I heard from Xiaoxi that if you didn't go to her, the probability of you not eating is even higher." Luo Mu gave Luo Hao a white look, "The food is on the table , you warm it up and eat first."

"Okay!" Luo Hao agreed, picked up the food on the table, and went into the kitchen.

"Mom, didn't you encounter anything today?" Luo Hao put the dishes in the microwave, walked out of the kitchen, and looked at Luo Mu carefully.

"It's okay, it's okay!" Mother Luo glared at Luo Hao, "What's the matter, are you still hoping that something will happen to your mother and me?"

"That can't be done. I'm just afraid that something will happen to you. I've been bitten by a snake for ten years and I'm afraid of well ropes. I'm worried about you." Luo Hao walked back to the kitchen angrily, heaving a sigh of relief, but he didn't notice Luo Mu's words. A thoughtful look.

Soon, Luo Hao heated up the food and sat down at the dining table to eat.

"What have you been researching recently?" Mother Luo asked suddenly as she watched the family ethics drama on TV.

"Oh, it's the force field generator that I gave you last time. It still has some flaws. I have to make up for it." Luo Hao didn't hide it, anyway, they all knew about the force field generator, "By the way, mom, force field generator You didn't tell anyone about the field generator, did you?"

"Of course, your mother and I are not stupid." Luo Mu said angrily, and then whispered something: At first, I felt embarrassed to say it, so that others would think my son was stupid, but now I dare not say it .

"Ahem——" Luo Hao heard what Luo Mu muttered in a low voice, and almost choked to death on the rice grains, and his mother always thought his son was stupid?

"Eat slowly, are you choking?"

............

In the evening, Luo Hao lay on the bed, chatted with Huang Xi for a while, and agreed not to see each other for a few days, he needed to research his battery first.

Huang Xi was a little unhappy about this, but he didn't say anything against him. As for Luo Hao, as long as he was doing business, Huang Xi would support him.

In the next few days, Luo Hao got up every day and went straight to the laboratory. Occasionally, Huang Xi would ask Uncle Zhang to drive her over to deliver food to Luo Hao. (As for whether there is any intention to check the post, you can guess for yourself.)

"You should eat first." Sitting in the laboratory, Huang Xi watched Luo Hao busy with his head down, and couldn't help but said, "The food is cold, and there is no place to heat it up here."

"Okay, I'll come right away." Luo Hao promised, but his body didn't move, he still stared down at the thing in his hand.

Huang Xi curled her lips. This guy said that half an hour ago. She stood up and walked to Luo Hao. After seeing that Luo Hao hadn't started operating the instrument, she stretched out her hand and pinched Luo Hao's ear: "I Said, let you go to eat first, did you hear me?!"

Luo Hao's body froze, and he smiled awkwardly: "I heard it, I heard it, eat now, eat now."

"Xiaohao, what are you researching? That force field generator from before? Is it okay to use it?" Huang Xi watched Luo Hao start eating, then sat aside and asked curiously.

"Research on batteries. The batteries of the force field generators you are using now are all disposable, and it is very laborious to make, and cannot be mass-produced. After the battery is dead, the force field generator cannot be used. Right?" Luo Hao didn't dare to say that the Super Energy brand battery was bought from the system, he couldn't make it at all.

"Then how is your research going?" Huang Xi asked.

"It went well. Fortunately, what I'm researching now is photovoltaic cells, which belong to the field of physics. If I want to study chemical energy batteries, I need to study chemistry." Luo Hao laughed, "The experiment is basically considered a success now. gone."
