Advances and outlook of TE-PCM system: a review

Abstract

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.

Diffuson‐Dominated and Ultra Defect‐Tolerant Two‐Channel Thermal Transport in Hybrid Halide Perovskites

“…All the MD simulations were conducted using the LAMMPS package [49] with periodic boundary conditions in three dimensions. The MYP potential [1][2][3]50,7] derived from first-principle calculations was used to describe the atomic interactions in MAPbI 3 with a timestep of 0.5 fs. The systems were equilibrated by the NPT ensemble relaxation at 350 K and 0 bar for 1 ns, and subsequently, by an NVE ensemble relaxation for 1 ns to fully relax these models.…”

“…Organic-inorganic hybrid halide perovskites, such as the prototypical CH 3 NH 3 PbI 3 (MAPbI 3 ), have attracted intensive attention as light absorbers in solar cells [1][2][3][4] , emitters in light emitting diodes (LEDs), [5] and thermoelectric materials [6,7] (Figure 1a) owing to solution-processability and high performance. In addition, facilitated by the movement of intrinsic iodine vacancy defects driven by applied voltage, [8] MAPbI 3 sandwiched between metal electrodes forms a memristor, and has been used in resistive switching memories [9] and artificial synapses.…”

Maximizing Electric Power through Spectral‐Splitting Photovoltaic‐Thermoelectric Hybrid System Integrated with Radiative Cooling

“…Peak efficiencies of 4.6% and 7.4% could be achieved with solar irradiances of 1 and 211 kW m −2 , respectively, as reported by Kraemer et al [13] Regardless of the structural form, a heat sink as the cold side is required in TEG, and various types are available. The common cooling methods include air cooling, [14] liquid cooling (e.g., water), [15] phase change materials, [16] etc., and the ambient is usually employed as the final cold source, resulting in a higher temperature in the cold side of TEG than the ambient temperature. As a clean and sustainable cooling technology that has been developed recently, daytime radiative cooling (RC) can emit heat to outer space with a temperature of 3 K through the "atmospheric window" (wavelength 𝜆 ranges from 8 to 13 μm) without any additional energy consumption, so as to achieve a lower cooling temperature than the ambient temperature.…”
