Abstract

The efficacy of using double layers of microencapsulated phase change material (MEPCM) layers as a passive thermal management medium for a photovoltaic (PV) module under practical operation conditions was evaluated by CFD numerical simulations. In an attempt to use the latent heat absorption by the system in summer and winter seasons, a high melting point MEPCM layer was combined with a low melting point MEPCM layer. In this way, the PV cell can be hopefully used in a variety of environmental conditions, thereby increasing the benefits and convenience of the system for practical applications. Based on the simulation results for the double-layer PV/MEPCM cell under winter and summer conditions, a total layer thickness of 3 cm was recommended, consisting of a 0.5-cm-thick low melting point (26 °C) layer and a 2.5-cm-thick high melting point (30 °C) layer.
