Abstract

The escalating energy demands and the imperative of environmental conservation necessitate advanced sustainable energy solutions. This study introduces a novel nanofluid spectrum-splitting photovoltaic/thermal system integrated with radiative cooling (RC) technology, termed NSS-RC-PV/T. This system optimizes solar spectrum utilization, enhances thermal management, and significantly improves the efficiency and flexibility of heat, electricity, and cooling outputs. Employing a reversible PV-Ag panel, the system adapts between PV/T and RC modes based on energy demands. A comprehensive mathematical model is established to evaluate its performance under realistic environmental conditions across China. Results indicate the maximum energy output of the system is 6438 MJ/m

, which is a 33.4% increase in annual energy output compared to the conventional PV/T system. The dynamic power response model also shows an increase of 5.8% (266 MJ/m

) compared to the daylight response model. This research underscores the potential of NSS-RC-PV/T systems in advancing renewable energy technologies and meeting modern energy needs.

利用柔性结构实现光热、光电和辐射冷却的可行性

能源需求不断增长，环境保护势在必行，因此需要先进的可持续能源解决方案。本研究介绍了一种集成了辐射冷却（RC）技术的新型纳米流体光谱分离光伏/热系统，称为 NSS-RC-PV/T。该系统优化了太阳光谱的利用，加强了热管理，并显著提高了热、电和冷却输出的效率和灵活性。该系统采用可逆式光伏-太阳能电池板，可根据能源需求在 PV/T 和 RC 模式之间进行调整。该系统建立了一个全面的数学模型，以评估其在中国实际环境条件下的性能。结果表明，该系统的最大能量输出为 6438 兆焦耳/平方米，与传统的 PV/T 系统相比，年能量输出增加了 33.4%。与日光响应模型相比，动态功率响应模型也显示增加了 5.8%（266 兆焦耳/平方米）。这项研究强调了 NSS-RC-PV/T 系统在推进可再生能源技术和满足现代能源需求方面的潜力。
