Application of phase change material in building integrated photovoltaics: A review

Abstract

The Phase Change Material (PCM) reduces thermal load and increases comfort inside the building. The paper discusses how and where PCM’s are used in Building Integrated Photovoltaics (BIPV), their impact on the performance of the PV module and built environment. In this review paper, BIPV-PCM system is categorized into two parts either Ventilated or Non-ventilated. Further, the thermophysical properties and temperature reduction in PV modules has been discussed. From the study, it is seen that most of the PCM’s were encapsulated with PV modules and building envelopes at the macro level. A significant reduction in temperature of modules and building envelopes occurs in both the categories is observed. However, the implementation of BIPV-PCM at a large scale and its economic viability is to be examined by the researchers in upcoming years.
