Science

Which outcome results when thermal energy excites an electron beyond the quantum yield threshold in a photovoltaic cell?

A)Increased electron-hole recombination probability
B)Auger generation reduces open-circuit voltage
C)Enhanced light trapping within active layer
D)Improved spectral response at band edge

💡 Explanation

Excess electron energy, caused by surpassing the quantum yield, allows Auger recombination. This is because the energy transfers to another electron, rather than creating multiple electron-hole pairs; therefore, Auger generation decreases the output voltage, rather than improving cell efficiency.
