← ScienceWhich outcome limits current production when applying excessive bias voltage across a silicon solar cell?
A)Increased electron-hole recombination rate✓
B)Decreased width depletion region
C)Elevated series resistance increases
D)Reduced concentration gradient diminishes
💡 Explanation
Increased bias voltage leads to accelerated electron-hole recombination in silicon, because trap-assisted processes become more probable due to abundant carrier populations; therefore efficiency drops dramatically, rather than ohmic losses dominating due to resistance.
