Manipulating Atomic Disorder and Mesoscale Architectures for High‐Efficiency Thermoelectric Modules

open access: yesAdvanced Science, EarlyView.
The in situ reaction of PbTiO3 precursor reacts in situ with the Bi0.5Sb1.5Te3 matrix, effectively enlarging the energy barrier for minority carrier excitation and suppressing bipolar diffusion, and predominantly scattering mid‐to‐low frequency phonons. Ultimately, a single thermoelectric module was fabricated to achieve a competitive efficiency of ∼7%
