← ScienceWhich process limits solar cell efficiency as excited electrons relax to lower energy states?
A)Non-radiative electron-hole recombination✓
B)Auger electron kinetic energy depletion
C)Diffusive photon energy band emission
D)Quantum entanglement excitation dissipation
💡 Explanation
When electrons transition back to their ground state without emitting a photon, non-radiative electron-hole recombination occurs because impurities or defects in the semiconductor lattice facilitate energy dissipation as heat instead. Therefore non-radiative recombination reduces cell voltage, rather than other processes requiring specific material properties or conditions.
