“…Multiple melting/solidifying cycles of the prepared PCM during long−term operation is requirement to verify the long−term stability and durability for at least 5,000 cycles (Maxa et al., 2017). Thus, the thermal stability analyses of the composite PCM to store latent heat continued from Nov 8, 2018 for 14 consecutive days or 14 charging/discharging cycles.…”

In this study, a micro-encapsulated phase change material (PCM) was composed of sugarcane wax−Al 2 O 3 composite as the core material and gelatin−gum Arabic as the polymer shell materials prepared by complex coacervation. The thermal behavior of solar panels integrated with this encapsulated PCM (EPCM) was investigated. The heat storage-dissipation performance and thermal stability of the sugarcane wax−based composite PCM layer with the heat capacity of 2.86 J/g·°C was influenced by its thickness. Increasing the composite PCM layer thickness from 4 mm to 7 mm could lower the module's front-facing glass temperature by 4% resulting in enhanced the photovoltaic power generation by 12% at the peak, because of the temperature storage ability of the composite PCM. Moreover, the thermal conductivity of the microencapsulated sugarcane wax was calculated using a steady-state one-dimensional energy balance equation. The thermal conductivities estimated across the composite PCM layer depth were found to be temperature dependent. A nonlinear regression of the power law thermal conductivity model gave a good agreement with the observed EPCM-surface temperatures.

“…[139] (ii) Modern synthesis tools, characterization tools, measurement tools, and so on must be investigated in order to use the proper complications and the targeted solution for those complications effectively. [140,141] (iii) Aside from the growing interest in improving the power factor of thermoelectric materials, the mechanical properties of the new generation of emerging thermoelectric materials and composites are receiving special attention. [142][143][144] Efforts should also be directed toward developing new designs of flexible thermoelectric devices and investigating potential applications, leveraging advantages such as mechanical flexibility while offsetting disadvantages such as low efficiency.…”

Our community is currently dealing with issues such as rising electricity costs, pollution, and global warming. Scientists are working to improve energy harvesting-based power generators in order to reduce their impacts. The Seebeck effect has been used to illustrate the capacity of thermoelectric generators (TEGs) to directly convert thermal energy to electrical energy. They are also ecologically beneficial since they do not include chemical products, function quietly because they lack mechanical structures and/or moving components, and may be built using different fabrication technologies such as 3D printing, silicon technology, and screen printing etc. TEGs are also position-independent, have a long operational lifetime, and can be integrated into bulk and flexible devices. This review gives further in investigation of TEGs, beginning with a full discussion of their operating principle, kinds, materials utilized, figure of merit, and improvement approaches, which include various thermoelectric material arrangements and utilised technologies. This paper also discusses the use of TEGs in a variety of disciplines such as automobile and biomedical.

“…Additionally, the latent heat PCMs show higher heat storage density than that of the sensible heat PCMs. Hence, latent heat storage using PCMs can satisfy the high-performance thermal energy storage requirements for different application areas such as advanced cooling packaging, 1 solar domestic hot water systems, 2 solar-powered air-cooling systems, 3 household refrigerating, 4 energy conservation buildings, 5 thermal management of electronics, 6 phase-change fibers, 7 and so on.…”

The fatty acid ternary eutectics such as capric-lauric-myristic acid, capric-lauric-palmitic acid, capric-lauric-stearic acid, capric-myristic-palmitic acid, capric-myristic-stearic acid, and capric-palmitic-stearic acid and quaternary eutectics such as capric-lauric-myristic-palmitic acid, capric-lauric-myristic-stearic acid, capric-lauric-palmitic-stearic acid, capric-myristic-palmitic-stearic acid, and lauric-myristic-palmitic-stearic acid were selected as solid-liquid phase-change materials (PCMs). And then the innovative ternary eutectic/polystyrene (PS)/ternary eutectic and ternary eutectic/PS/quaternary eutectic form-stable phase-change composite fibrous membranes (PCCFMs) were directly prepared by the co-electrospinning method under the same spinning parameters. The as-prepared form-stable PCCFMs exhibited three-dimensional fibrous network structure with the average fiber diameter of about 410–780 nm according to the scanning electron microscopy images. The adhesion among nanofiber intersections was observed occasionally. The differential scanning calorimetry results showed that fatty acid eutectics have been successfully combined into the form-stable PCCFMs, and their melting peak temperatures mostly ranged from 15°C to 21°C with a temperature interval of 1°C. Moreover, the phase-change enthalpies reached about 40–61 kJ kg−1. It is concluded that these electrospun form-stable PCCFMs with appropriate phase-change temperatures could be considered as potential PCMs to be applied in thermo-regulating fibers and textiles.
