“…Combined with the above analysis, it can be inferred that the phase change coating has anticondensation characteristics, which are based on the temperature control characteristics of the coating. That is, when the phase transition temperature is between the ambient temperature and the surface temperature, there is a “temperature platform” phenomenon during the coating temperature drop [15], which slows down the temperature drop, thereby reducing the temperature difference between the surface temperature and the dew point and slowing down the condensation.…”

Metal cabinets such as switch cabinets and ring network cabinets have the advantages of small footprints and good protection for equipment and offer neat and orderly protection. They are widely used in power systems. In a hot and humid environment, condensation can easily cause equipment to age and even cause insulation failure. Therefore, research on reliable anticondensation methods is of great significance for the safe operation of power equipment. In this study, phase change capsules with phase transition temperatures of 22 and 32 °C were used as fillers and liquid silicone rubber was used as a matrix to prepare liquid silicone rubber composites filled with phase change capsules for a temperature-control coating. Studies have shown that liquid silicone rubber coatings containing phase change capsules can significantly enhance the anticondensation performance of metal cabinets. By using a temperature-control coating on the surface where the cabinet experiences condensation, the temperature difference between the surface and the dew point is reduced, thereby slowing down the condensation rate and even preventing condensation.

“…Many designs were presented to enhance heat dissipation through the PCM for attaining uniform cooling over PV rear surface. [13][14][15] Nevertheless, active cooling can enhance the PV system performance by about 10 % to 20 % in the highest range. From economical point of view, if these systems are well optimized, their cost will be lowered depending on the reduction of the running cost.…”

Finding the most optimal configuration of hybrid concentrator photovoltaic (CPV)-thermoelectric power generator (TEG) system integrated with a microchannel heat sink (MCHS) is of great importance to achieve the best performance. Thus, two different hybrid configurations were chosen for the study including CPV/TEG/heat sink and CPV/heat sink/TEG. In addition, the performance of both hybrid configurations was compared with standalone CPV/heat sink and TEG/heat sink. In the conventional hybrid design, the TEG was directly attached to the back surface of the CPV module, whereas the other side of the TEG was integrated with MCHS. In the new hybrid design, the MCHS was sited between the CPV and the TEG module as both sides were subjected to concentrated solar radiation. Effects of varying the simulated solar

“…It is important to extract the dissipated heat from the multi-junction solar cell, since the increase in solar cell temperature, in the short term, can lead to power conversion efficiency loss and, in the long-term, degradation of the lifetime of the solar cell [29][30][31][32][33]. The most commonly used methods for extraction of heat from an electrical system are active cooling, phase change material (PCMs) for heat storage [34][35][36][37][38], and passive cooling [39,40].…”

Temperature rise in multi-junction solar cells reduces their efficiency and shortens their lifetime. We report the results of the feasibility study of passive thermal management of concentrated multi-junction solar cells with the non-curing graphene-enhanced thermal interface materials. Using an inexpensive, scalable technique, graphene and few-layer graphene fillers were incorporated in the non-curing mineral oil matrix, with the filler concentration of up to 40 wt% and applied as the thermal interface material between the solar cell and the heat sink. The performance parameters of the solar cells were tested using an industry-standard solar simulator with concentrated light illumination at 70× and 200× suns. It was found that the non-curing graphene-enhanced thermal interface material substantially reduces the temperature rise in the solar cell and improves its open-circuit voltage. The decrease in the maximum temperature rise enhances the solar cell performance compared to that with the commercial non-cured thermal interface material. The obtained results are important for the development of the thermal management technologies for the next generation of photovoltaic solar cells.
