Which mechanism leads to reduced efficiency when rapid cooling induces crystal lattice defects in thermoelectric generators?

A)Phonon scattering
B)Decreased Seebeck coefficient
C)Increased electrical conductivity
D)Reduced thermal gradient

💡 Explanation

Rapid cooling introduces dislocations, causing increased phonon scattering, therefore reducing the overall thermal conductivity, because phonons are scattered more frequently. This decreases efficiency, rather than increasing electrical conductivity under thermal gradients.
