← ScienceWhich efficiency limitation arises in a thermoelectric generator undergoing rapid temperature cycling?
A)Increased entropy generation from thermal lag✓
B)Decreased Seebeck coefficient from dopant diffusion
C)Reduced thermal conductivity due to phonon scattering
D)Elevated electrical resistance from contact degradation
💡 Explanation
During rapid temperature cycling, thermal lag induces temperature gradients within the thermoelectric modules, causing increased entropy generation from irreversible heat transfer and reducing efficiency. Therefore, entropy generation dominates, rather than changes to material properties or contact resistance which are comparatively slower degradation processes.
