Abstract

Abstract: Growing demands for energy, gradual depletion of fossil resources and high environmental impacts require that current energy production models be replaced by more sustainable technology. Thus, research efforts focused on improving energy efficiency and material efficiency are considered extremely relevant. In the following work, the influence of incorporating PCMs (phase change materials) on electricity conversion efficiency discussed along with hot spot prevention and lifetime increases in BIPV (building-integrated photovoltaics). The main goal is to evaluate the operational temperature control in a BIPV with or without PCMs considering different climatic severities. A design parameter analysis was conducted, and the importance of suitable PCMs and proper system designs are revealed. Also, this study indicates that areas with different climatic severities must be considered for widespread evaluations of this technology application to impact diverse regions. Additionally, an environmental analysis based on the LCA (life cycle assessment) methodology was performed using the SimaPro software. The results show that a positive environmental impact is generated by PCM applications because of the decreased amount of consumed resources in BIPV manufacturing, which is related to the lifetime extension resulting from the ability of PCMs to store latent heat and prevent premature physical damage to the BIPV. Highlights: Thermal-regulating PV through innovative solutions based on PCM is focused. A proper design parameter and PCM selection will enhance the PV performance. T pv/pcm was reduced by 8°C and η pv/pcm improved by 3% compared to η pv, in Zaragoza. The PCM-related thermal regulation reduces premature degradation in PV systems. The application of PCM in PV improves the energy and environmental efficiency.
