New Formula

Caption

This image shows the effect of the new formula, (ZT)eng and (PF)eng, based on cumulative temperature-dependent properties of p-type TE materials. (A) Temperature-dependent ZT. (B) Average ZTs by Zint Tavg (open symbols) and Ztarg Tavg (solid symbols). (C) (ZT)eng. (D) Efficiency predicted by simulation (open symbols), Eq. 1 (dashed lines), and Eq. 2 (solid lines). (E) T-dependent . (F) ?T-dependent (PF)eng, and power density as the inset. The cold side temperature is fixed as Tc = 50 degrees C for all analysis (B)-(F) on MgAgSb (33), K-PbTeSe (21), SKU (14), and HH (13).
