Owing to the economic recession due to the Coronavirus disease (COVID-19) pandemic, energy-efficient building retrofitting has been considered as an integrated solution to recover the economy and maintain global greenhouse gas reduction. As part of retrofitting existing building-integrated photovoltaic systems during building renovations, this study evaluated the energy generation potential of a thermoelectric generator-assisted building-integrated photovoltaic system with a phase change material. The combination of a thermoelectric generator and phase change material with photovoltaic systems results in solar cell temperature reduction and additional electricity output owing to the Seebeck effect, increasing the total generated energy from the system. Simulations of the proposed system were performed using MATLAB R2020a, based on transient energy balance equations. The appropriate melting temperature and thickness of the phase change material were derived to maximize the annual electricity generation of the proposed system from simulations of 12 design days in each month. The proposed system with the selected phase change material conditions exhibited a 1.09% annual increase in generation output and 0.91%, -1.32%, 2.25%, and 3.16% generation improvements from spring to winter, compared with the building-integrated photovoltaic system alone. Theoretically, the proposed system is expected to generate 4.47% more energy by minimizing the thermal resistance of the system and improving thermoelectric generator performance.
由于冠状病毒病（COVID-19）大流行导致经济衰退，节能建筑改造已被视为恢复经济和维持全球温室气体减排的综合解决方案。作为建筑翻新期间对现有建筑集成光伏系统进行改造的一部分，本研究评估了一种带有相变材料的热电发电机辅助建筑集成光伏系统的发电潜力。热电发电机和相变材料与光伏系统的结合，由于塞贝克效应，可降低太阳能电池温度并产生额外的电力输出，从而增加系统的总发电量。基于瞬态能量平衡方程，使用MATLAB R2020a对所提出的系统进行了模拟。通过对每个月12个设计日的模拟，得出了相变材料的合适熔化温度和厚度，以使所提出系统的年发电量最大化。与单独的建筑集成光伏系统相比，在所选择的相变材料条件下，所提出的系统发电量年增长1.09%，从春季到冬季发电量分别提高0.91%、-1.32%、2.25%和3.16%。从理论上讲，通过最小化系统的热阻并提高热电发电机性能，预计所提出的系统可多发电4.47%。
