The energy storage application plays a vital role in the utilization of the solar energy technologies. There are various types of the energy storage applications are available in the todays world. Phase change materials (PCMs) are suitable for various solar energy systems for prolonged heat energy retaining, as solar radiation is sporadic. This literature review presents the application of the PCM in solar thermal power plants, solar desalination, solar cooker, solar air heater, and solar water heater. Even though the availability and cost of PCMs are complex and high, the PCMs are used in most solar energy methods due to their significant technical parameters improvisation. This review's detailed findings paved the way for future recommendations and methods for the investigators to carry work for further system developments.

“…The photovoltaic cell or module operating temperature depends on solar radiation, the ambient temperature, wind speed and direction, the PV module technology and materials used, total irradiance and relative humidity [2,8,9,10,11]. The temperature is a significant factor impacting PV cell and PV module performance [2]. Controlling the PV cell temperature involves controlling accumulated back surface heat in the PV cell.…”

“…Solar energy resources are immense, but unfortunately solar electricity has only a small share of total world electricity production. But photovoltaic technology has the potential to deliver some 11% of global electricity demand by 2050 [ 1 , 2 ]. Photovoltaic technology is an alternative energy source that can play a major role in providing domestic power supplies through Building-Integrated Photovoltaic (BIPV) technology.…”

“…The quality of the electricity produced depends on the photovoltaic conversion mechanism. This mechanism generates heat increasing the PV cell (i.e., PV module) temperature and this can adversely impact electricity generation efficiency [ 2 ] resulting in less electrical energy being delivered than the rated capacity of the modules. In order to predict the power output of the electrical model (e.g., in [ 4 , 5 ]), it is necessary to accurately estimate the operating temperature of the PV cell and this is usually obtained using a thermal model.…”

Photovoltaic (PV) solar energy enables direct production of electricity. The photovoltaic effect produced in the solar cells converts light energy from the sun's rays into electricity. Some of the solar radiation absorbed by a PV module is not converted into electricity but takes the form of an increase in the temperature of the module, reducing its electrical efficiency. The operating temperature of PV modules generally affects the performance of the PV system; performance also depends on numerous variables such as ambient temperature, wind speed, wind direction, total irradiance, dust accumulating on the PV module face and relative humidity. In this study different models for predicting the operating temperature of PV modules have been investigated. The models' relevance to PV module technology and climatic conditions in Errachidia city (coordinates: 31 55 0 55 00 north, 4 25 0 28 00 west) in the Drâa Tafilalet region was examined. The models that factor in wind data predict PV cell temperature better than the standard approach which does not include wind data. The models' accuracy was estimated based on R 2 and RMSE values. A model is more accurate the higher the R 2 is and the lower the RMSE is. In addition, we noticed that the models investigated are more accurate for a short time period during the day.
