Comparison of thermoelectric performance for our sample with other Cu₂SnSe₃-based thermoelectrics. (a) Temperature dependence of ZT value for Cu₂Sn_0.94Cd_0.06Se₃, Cu_1.85Ag_0.15Sn_0.9Cd_0.1Se₃, and other reported Cu₂SnSe₃-based thermoelectric systems. (b) Comparison of the maximum ZT (ZT_max) at 800 K and average ZT (ZT_ave) from 423‒800 K for this work and other Ag-optimized Cu₂SnSe₃ systems.
