“…b) Peak zT values of state‐of‐the‐art Cu 2 X‐based thermoelectric materials and their derivatives as a function of publication year. c) Maximum energy conversion efficiency (η max , estimated from peak zT values and corresponding T ) and d) material costs (in the unit of US$ kg −1 ) of Cu 2 Te, Cu 2 Se and Cu 2 S‐based thermoelectric materials, respectively …”

“…The practical applications of thermoelectric materials are highly limited by both their efficiency and cost . Figure c,d shows the calculated maximum energy conversion efficiency (η max ) of Cu 2 X‐based thermoelectric materials (applied as power generators) estimated from peak zT values at corresponding temperatures and the estimated material costs .…”

“…[123,129,160] The practical applications of thermoelectric materials are highly limited by both their efficiency and cost. [23,[161][162][163] Figure 1c,d shows the calculated maximum energy conversion efficiency (η max ) of Cu 2 X-based thermoelectric materials (applied as power generators) estimated from peak zT values at corresponding temperatures and the estimated material costs. [2,43,99,[118][119][120][121][122][124][125][126][127][128][161][162][163][164] As can be seen, Cu 2 Se-based thermoelectric materials possess highest zT values and subsequently highest η max , as well as intermediate material cost.…”

[2,120,122,124,125,127] Although, thermoelectric performance of Cu 2 S-based materials is not as outstanding as that of Cu 2 Se-based counterparts, due to the high earth-abundancy of S, [165] the costs of Cu 2 S-based materials are nearly half of the Cu 2 Se-based ones, which leads to a high competitiveness for commercialization.…”
