a The measured temperature-dependent figure of merit, Z, for Bi0.88Sb0.12 polycrystals with 0.5 T and without a magnetic field. The measured Z is compared to that of other prevailing TE materials18,29. b The maximum cooling temperature differences between the hot and cold sides of the module as a function of Th. The inset shows the experimental setup for the thermoelectric cooling measurement with a uni-couple module consisting of n-type Bi0.88Sb0.12 and p-type Bi0.5Sb1.5Te3 legs.
