← ScienceWhich outcome can occur when a semiconductor's band gap changes during laser annealing?
A)Increased short-circuit current density✓
B)Increased reverse saturation current
C)Reduced built-in potential voltage
D)Reduced output quantum efficiency
💡 Explanation
A band gap decrease caused by transient changes during laser annealing increases electron-hole pair generation via Photoluminescence; therefore, the short-circuit current density increases, because more carriers are available, rather than reduced quantum efficiency.
