Application of phase change materials in photovoltaic building integration system

With the advent of the energy crisis, the utilization of renewable energy has become the main melody of energy research. Building-integrated photovoltaic (BIPV) systems effectively reduce building energy consumption by combining solar energy utilization with building envelope to generate electric energy. However, the integration of photovoltaic (PV) into the building increases photovoltaic 's temperature, which reduces photovoltaic 's performance and shortens its life. In recent years, researchers have made efforts to solve photovoltaic efficiency degradation caused by high operating temperatures. Integrating phase change materials (PCM) with BIPV systems can reduce the temperature of photovoltaic panels and provide thermal storage for buildings. This study reviews the application of PCM in BIPV and building integrated photovoltaic thermal (BIPV/T) systems. This study focuses on experiments, numerical simulations, and optimization designs to understand technological progress better and and provide support for promoting the large-scale commercialization of the systems.
