To achieve practical applications of transverse thermoelectricity, it is essential to discover novel high-performance polycrystalline transverse magneto-thermoelectric materials. Herein, we find that polycrystalline AgTe exhibits a peak Nernst thermopower of 625 μV K at 75 K under a magnetic field of 14 T. Such a high value might originate from the enhanced bipolar effect and the crossed linear band near the low-temperature N-P transition. Our studies suggest the promising potential of AgTe-based materials for energy conversion utilizing the Nernst effect and open up a new avenue for the development of novel magneto-thermoelectric materials.
