Relationship between thermoelectric figure of merit and energy conversion efficiency.
TL;DR: An engineering dimensionless figure of merit (ZT)eng and an engineering power factor (PF)eng are defined as functions of the temperature difference between the cold and hot sides to predict reliably and accurately the practical conversion efficiency and output power, respectively, overcoming the reporting of unrealistic efficiency using average ZT values.
