Chapter 848: Chapter 847: All It Takes Is One Sentence

Upon hearing the research institute’s director was nad Chang, Jiang Mianmian’s eyes went wide.

Oh my god, it’s Director Chang! He’s a giant among giants in the research world; his illustrious achievents are in all kinds of textbooks in the future.

I can’t believe I’m so fortunate to witness the style of such a big shot in person.

With stars in her eyes, Jiang Mianmian looked at this great historical figure, nearly forgetting what she ca here to do.

Director Chang, however, paid no mind to these formalities and went straight to the point: “Please take out the solar charging panel and let have a look.”

Elder Yu, knowing the temperant of his old friend, wasn’t surprised by this and good-naturedly handed over the power panel: “Here, this is the solar panel. Mianmian explained the principle to earlier, but you know, I’m just a layman; no matter how clearly she explains, I still don’t understand.”

Director Chang accepted the panel with a serious expression and carefully examined it. After just a few minutes, he understood the materials of this solar panel almost entirely.

After inspecting the outer materials, he looked at Jiang Mianmian and asked, “Child, can you demonstrate it for ?”

“Yes, of course, Director Chang. The electricity stored inside was charged at Grandpa Yu’s house just now, so it shouldn’t be much now. Let’s go to the window; we can charge and demonstrate at the sa ti.” Although facing such an important figure, Jiang Mianmian was a bit nervous, but she still explained calmly and confidently.

“Alright.” The group walked to the window, and after basking it for a while, Jiang Mianmian pressed the switch, and the blades began to slowly turn.

Director Zhang’s face turned flushed with excitent upon seeing this; this Jiang Mianmian is incredible, considering how young she is, she’s given surprise after surprise.

Director Chang also got very excited upon seeing this, and his usually restrained emotions showed a rare smile, complinting twice in one go.

“Good, very good. Child, can you tell about the principle of solar power generation?”

Jiang Mianmian nodded eagerly: “Of course I can, Director Chang. My solar panel is made of semiconductors. When sunlight hits the semiconductor, so of the light gets reflected by the surface, while the rest is absorbed or passes through.”

Humans can only utilize the absorbed light, and among the absorbed light, so is converted to heat, while other photons collide with the valence electrons of the semiconductor’s atomic structure, creating electron-hole pairs.

Thus, the light energy is converted into electrical energy in the form of created electron-hole pairs.

This explanation by Jiang Mianmian made Director Chang suddenly realize; he’s been researching solar power technology for many years.

But due to the international technology blockade and the severe lack of relevant information dostically, so principles and technologies always felt like a veil over his eyes, unclear and incomprehensible.

Yet, that single explanation from Jiang Mianmian just unraveled the puzzle that had troubled him for years.

“I get it now!” Director Chang’s eyes lit up, and clutching the solar panel like a priceless treasure, he began studying it ticulously.

For soone as extraordinarily smart as him, a single sentence is all it takes to provide a flash of insight and clarity.

“Elder Yu, Mianmian, I’m really sorry, but once our director starts researching, he’s extrely focused. Let take you to the office to wait for a bit.” Director Zhang gently said to the group.
