Fig. 4: Measured conversion efficiency and output power.
From: Ultrahigh thermoelectricity obtained in classical BiSbTe alloy processed under super-gravity
a Electric current dependence of the conversion efficiency, and the inset shows a photograph of the module. b Maximum conversion efficiency with different temperature differences. c Electric current dependence of output power. d Power density with different temperature differences. The hot-side temperature was set to 423 K or 473 K. The corresponding cold-side temperature was 286 K or 289 K. Data from previous studies are shown for comparison7,40,66,67,68,69.
