← ScienceWhich mechanism causes photocurrent generation when light strikes silicon?
A)Electron-hole pair creation (photogeneration)✓
B)Increased phonon scattering (Umklapp)
C)Enhanced electron-phonon coupling
D)Reduced dielectric constant polarization
💡 Explanation
Electron-hole pair creation (photogeneration) facilitates photocurrent because incident photons promote electrons across silicon's bandgap, creating electron-hole pairs. Therefore, the electron-hole pairs contribute to current flow rather than increased scattering from options B and C.
