← ScienceWhich efficiency loss occurs when exceeding a solar cell's Voc?
A)Increased non-irradiative Shockley-Read-Hall recombination✓
B)Photon recycling suppresses bulk recombination
C)Surface plasmon resonance quantum enhancement
D)Auger recombination dominates radiative losses
💡 Explanation
Exceeding Voc increases non-irradiative Shockley-Read-Hall recombination because excess carriers accumulate at defect sites, dissipating energy as heat, therefore reducing cell efficiency, rather than radiative recombination maintaining higher voltages.
