The Performance of all Mg3Sb2-based Effective and Reliable Same-parent Thermoelectric Module

Caption

(a) Output voltage (hollow) and output power (solid) of a fully Mg3Sb2-based module as a function of current under different measuring temperature differences. (b) Measured and predicted conversion efficiency as a function of temperature difference of our two-pair and eight-pair modules. (c) Comparison of the efficiency of existing same-parent TE modules at a temperature difference of 380 K over the last decade. (d) Change of the maximum output power (ΔPmax) and efficiency (Δηmax) of the 8-pair Mg3Sb2-based module during 150 thermal cycles when hot-side temperature cycles between 673 K and 473 K.
