Lead telluride has good performance as a thermoelectric material, partly due to the low thermal conductivity and partly due to its electrical properties. This plots exhibits the Seebeck coefficient (green curve) and electrical conductivity (blue curve) between room temperature and 250°C. The dotted green line represents the PTB1)-certified values. A good correlation can be observed indicating the reliability of the system.
