← ScienceWhich risk increases when a thermoelectric generator's cold-side heat exchanger experiences reduced convective cooling?
A)Reduced Seebeck coefficient efficiency
B)Increased reverse-bias diode leakage
C)Greater temperature differential decrease
D)Accelerated hot-side creep deformation✓
💡 Explanation
Hot-side creep deformation gets accelerated because reduced cooling elevates the temperature gradient across the thermoelectric material, intensifying the thermally activated creep. Therefore, creep accelerates rather than diode leakage or efficiency reductions under these conditions.
