“…A general rule of thumb indicates that an increase in the thickness of PCM leads to sustainability of the T PV reduction for longer time, as well as creates the thermal conduction barrier during thermal absorption. To overcome this issue, several researchers have incorporated thermal additives to enhance the thermal conductivity of the PCM by adding metal foam [62], metal scrap [63], copper powder [64], graphite [64], expandable graphite [65], and nanoparticles [48].…”

The solar photovoltaic (PV) system is emerging energetically in meeting the present energy demands. A rise in PV module temperature reduces the electrical efficiency, which fails to meet the expected energy demand. The main objective of this research was to study the nature of OM29, which is an organic phase change material (PCM) used for PV module cooling during the summer season. A heat transfer network was developed to minimize the experimental difficulties and represent the working model as an electrical resistance circuit. Most existing PV module temperature (TPV) reduction technology fails to achieve the effective heat transfer from the PV module to PCM because there is an intermediate layer between the PV module and PCM. In this proposed method, liquid PCM is filled directly on the back surface of the PV module to overcome the conduction barrier and PCM attains the thermal energy directly from the PV module. Further, the rear side of the PCM is enclosed by tin combined with aluminium to avoid any leakages during phase change. Experimental results show that the PV module temperature decreased by a maximum of 1.2 °C using OM29 until 08:30. However, after 09:00, the OM29 PCM was unable to lower the TPV because OM29 is not capable of maintaining the latent heat property for a longer time and total amount of the PCM experimented in this study was not sufficient to store the PV module generated thermal energy for an entire day. The inability of the presented PCM to lower the temperature of the PV panel was attributed to the lower melting point of OM29. PCM back sheet was incapable of dissipating the stored PCM’s thermal energy to the ambient, and this makes the experimented PCM unsuitable for the selected location during summer.

“…Results confirmed that higher thermal conductivity of PCM should be preferred to achieve high-temperature drop and yield. A similar type of study [52] was intended to study the effect of pure PCM (thermal conductivity of 0.18 W/mK and combine PCM (PCM (70%), copper (20%), graphite (10%), (thermal conductivity of 95.38 W/mK) on the electrical and thermal behaviour of PV module. It was seen that thermal conductivity is proportional to electrical performance.…”

The temperature of Photovoltaic (PV) module rises by absorbed incident solar radiation and causes subsequent drop off in electrical efficiency. To overcome this ill effect, an appropriate material must be used to absorb the heat and maintain the temperature of PV module. The purpose of present study is to review and understand various cooling techniques used to enhance cooling and electrical performance. The emphasis was placed on design and operating parameters like absorber configuration, flow pattern, flow rates, climatic conditions, radiation intensity, wind speed, thermal conductivity, glazing, concentration on the electrical and thermal characteristics. The reviewed papers include theoretical analysis, computer simulation, solar simulator and on-field experiments. The study states that the proper selection and utilization of cooling technology, design and process parameters are the key elements in the solar photovoltaic (PV) system to achieve optimum performance.

“…Lin et al [14] floored all the internal walls of a room with PCM to study the influence of PV/T solar collector and PCM on indoor thermal environment. Through experiments and transient energy balance approach, Hachem et al [15] and Kibria et al [16] studied the effect of PCM on the performance of PV board and concluded that PCM could decrease the temperature of PV board and increase the electrical efficiency. Curpek and Hraska [17] compared and studied the PV board with and without PCM as well as the flow passage with and without ventilation, the results showed that natural ventilation of PV façade with added PCM could reduce the temperature of PV board better.…”

This paper proposes a novel PV-Trombe wall system combined with phase-change material, which is named as PV-PCM-Trombe system. The work mainly experimentally studies the effectiveness and characteristics of using phase change materials to improve the overheating problem of PV-Trombe wall in summer. Through experiments, the photoelectric performance of the system using phase-change board surfaces with and without a matte black paint lacquer are compared; moreover, the influence on thermal environment of building is evaluated. The results indicate the PV-PCM-Trombe wall system shows an effective cooling effect on PV cell in both experiments and that the surface lacquer coating treatment of PCM plates affects little the photoelectric performance of the system and can reduce the working temperature of PV cell.
