Besides, the standard deviation (SD) of temperature within the cell is also employed as an important factor to evaluate the temperature uniformity degree within the cell, which can be expressed as: (7) SD = 1 N − 1 ∑ j = 1 N T j − T aver 2 where N is the number of temperature observations (i.e., number of grid vertex) in the cell, T j is the cell temperature at
Liquid nitrogen of temperature 77 K was used in the experimental setup to absorb waste heat from the hot side of the TEG and dissipate it to the environment, achieving a larger temperature gradient. Power generation is achieved in both the liquid phase and the gas phase with the liquid phase producing the largest temperature difference.
