Abstract
Building Integrated Photovoltaics (BIPV) is one of the most promising applications for Photovoltaics (PV). However when the temperature on the BIPV increases, the conversion efficiency deteriorates. A PV/PCM system using Phase Change Materials (PCM) for BIPV thermal control has been experimentally and numerically studied recently. One of the main barriers for this application is how to improve the low thermal conductivity of the PCM for longer thermal regulation on PV. Although the metal fins can improve the heat transfer, the effect of the thermal regulation period declined as the metal mass increased along with the decreasing thermal control period. A modified PV/PCM system integrated with two types of phase transient PCMs for improving the heat regulation need to be investigated. The performance of using PCMs with a set of different phase change temperatures is expected to improve the heat regulation on the PV/PCM system and increase the thermal regulation time. In this study a series of numerical simulations tests have been carried out in realistic conditions, and the thermal regulation of the PV/PCM system in optimised metal cells using a different range of phase transient temperature PCMs has been discussed.
