Abstract

Smart solar façades represent a promising approach to reducing building energy consumption and advancing net-zero goals. By incorporating concentrating photovoltaic (CPV) technology, these systems can generate more electricity with reduced material use, enhancing both environmental sustainability and cost-effectiveness. In this study, we designed, fabricated, tested, and analysed a smart solar façade featuring a linear concentrating element with a concentration ratio of 2.49 × . For the first time, standard Passivated Emitter and Rear Contact (PERC) solar cells were integrated into such a configuration. The façade achieved a peak power generation of 174 W/m2 while transmitting 63 % of visible light, thereby maintaining natural daylight within interior spaces. Thermal analysis showed that under standard 1 sun illumination (1000 W/m2), the solar cell reached a peak temperature of 339 K. Additionally, a comprehensive economic evaluation indicated payback periods ranging from 7 to 11 years across various climatic zones, highlighting the system’s potential for widespread adoption in sustainable building applications. Beyond traditional economic assessment, this study incorporates a holistic sustainability analysis, including embodied carbon payback, climate-adaptive performance, and the potential to achieve green certification.

具有线性聚光光伏的智能太阳能幕墙：设计、测试、经济和可持续性评估

智能太阳能幕墙代表了减少建筑能耗和推进净零目标的一种有希望的方法。通过结合聚光光伏（CPV）技术，这些系统可以在减少材料使用的情况下产生更多的电力，从而提高环境的可持续性和成本效益。在这项研究中，我们设计、制造、测试和分析了一个具有线性聚光元件的智能太阳能电池板，其聚光比为2.49 ×。这是第一次，标准钝化发射极和后接触（PERC）太阳能电池被集成到这样的配置。立面的峰值发电量为174瓦/平方米，同时透射63%的可见光，从而保持室内空间的自然采光。热分析表明，在标准1个太阳光照（1000 W/m2）下，太阳能电池的峰值温度为339 K。此外，综合经济评估表明，在不同的气候带，投资回收期从7年到11年不等，突出了该系统在可持续建筑应用中广泛采用的潜力。除了传统的经济评估，本研究还结合了整体的可持续性分析，包括隐含碳回报、气候适应绩效和实现绿色认证的潜力。
