Which process limits maximum energy conversion efficiency in thermoelectric generators at high temperatures?

💡 Explanation

At higher temperatures, increased thermal conductivity occurs because phonon transport enhances heat leakage from the hot side to the cold, bypassing the energy available for electric conversion. Therefore, increased conductivity lowers efficiency, rather than phonon scattering, Seebeck reduction or radiative loss which while impactful operate via distinct limitations.
