Which outcome occurs when a high-energy photon strikes a silicon solar panel's valence band orbital?

A)Electron-hole pair generation for current
B)Increased phonon vibration reducing bandgap
C)Dielectric breakdown damaging the crystal
D)Selective absorption by n-type dopants

💡 Explanation

When a photon with sufficient energy strikes a valence band orbital, electron-hole pair generation occurs because of the photoelectric effect, creating free carriers for current. Therefore electron-hole pair generation results, rather than increased phonon vibration, dielectric breakdown, or selective absorption, which require different interaction mechanisms.
