This review reports the most recent developments of thermoelectric (TE) system coupled with phase change material (PCM) and its promising integration options within various PCM deployment and structure design. These innovative TE coupled with PCM (TE-PCM) systems provide heat/cold energy with additional electric power which implies better harnessing of multiform energy. Fundamentals of TE-PCM system including thermoelectric effect are presented along with a basic mathematical formulation of the physical problem. The classification principles and configuration types of such systems are also summarized. The most representative studies related to the utilization of TE-PCM system in diversified application scenarios and their compatibility with other energy systems have been comprehensively reviewed and analyzed, including the component and structure optimization. In-depth analysis of the main technical and operational challenges in the future has been carried out, and the prospective development of more efficient TE-PCM system and its hybrid configurations are projected based on the current technological level.

“…For balancing the total heat flux produced by the TEG module, the rate of heat flow into the hot junction and the rate of heat rejected from the cold junction of the module can be determined using Eqs. (18) and (19) [ 53 , 54 ].

Where,

is heat rate input on the hot side,

is heat rejected from the cold side,

is the temperature of a hot side, T c is the temperature of the cold side, k is thermal conductivity, N is the number of semiconductor thermocouples, I is the electric current of the module, and R is the resistance of the module.…”

“…[14] Thus, considerable research has been undertaken on PCM/TEDs for use in places where the variation in temperature is large, such as on airplane sidewalls [29,30] and outdoor places with direct sunlight irradiation. [31][32][33][34] . For example, in the case of PCM/TEDs Power generators that convert daily air temperature cycles to electricity should have both high power output and wide operating temperature range.…”

Power generators that convert daily air temperature cycles to electricity should have both high power output and wide operating temperature range. Herein, a power generator combining a thermoelectric device and a mixture of various encapsulated alkanes that undergo continuous phase transitions induced by ambient temperature cycles is demonstrated. The operating temperature range of such a power generator can be extended by selecting appropriate alkane capsules to be incorporated into the device. A power generator with an operating temperature range of −0.2–37.2 °C is demonstrated; this operating temperature range is obtained when the temperature difference between the highest and lowest temperatures of the ambient temperature cycle is 14.2 °C, which is the equivalent environment in a Stevenson screen outdoors. The wide operating temperature range would permit power generation from daily temperature variations in many temperate and subtropical countries. The electric powers obtained by this power generator when placed in an indoor room and an outdoor Stevenson screen are 180 and 300 µW, respectively. Our temperature cycle‐based power generators pave the way for power sources that can generate electricity semi‐permanently in a broad range of environment.
