Study of a Thermal Storage System Through Latent Heat With Phase Change: Application to the Cooling of a Photovoltaic Sensor

Thermal storage holds immense importance across various domains due to its numerous advantages in managing industrial processes. One notable challenge in photovoltaic sensors lies in the elevated temperatures of their cells during intense sunlight, resulting in reduced efficiency. To address this issue, a passive system incorporating a Phase Change Material (PCM) has been implemented to capture and dissipate this heat. The study of the PV/PCM system was conducted using COMSOL Multiphysics software. However, a primary focus was on identifying and controlling diverse parameters, both physical and geometrical, to achieve a well-optimized model, with a specific emphasis on improving thermal efficiency. As a result, there is a pressing need to develop efficient systems for heat collection during periods of high irradiance.
