"Stimulated in the presence of light—or in other words, the equilibrium junction is disrupted, leading to a potential difference?"
"But in this case, the actual environment of stimulation might be invisible to the naked eye..."
Watching Old Fa talk eloquently, Xu Yun remained silent.
However, his tightly clasped hands indicated that his heart was not calm at the moment.
As everyone knows.
The essence of the photovoltaic phenomenon comes down to the atomic energy band structure, involving the concepts of valence band and conduction band.
The so-called valence band refers to the region relatively close to the atomic nucleus.
The electrons here are tightly held and cannot easily escape.
The conduction band, on the other hand, is the region far from the atomic nucleus, where electrons are unregulated and relatively free.
If an external electric field sets these electrons in motion, the material conducts electricity.
