Description
Summary:The efficiency of electricity generation by photovoltaic (PV) cells is inversely proportional to their temperature. In order to maximize the efficiency, the possibility of latent heat cooling system application was analyzed. The work deals with the thermal behavior simulations of photovoltaic cells cooled by integrated aluminum honeycomb structure with built- in microencapsulated phase change material (mPCM). The low thermal conductivity of PCM is a factor limiting the utilization of its full heat capacity at the required thicknesses. The honeycomb structure made of high thermal conductivity material overcomes this disadvantage and ensures more intensive heat transfer across the PCM layer thickness. Thermal behavior of aluminum honeycomb structure filled with mPCM was compared to the standard PV element without any additional cooling system and finally without use of high conductive structure.
