Passive daytime radiative cooling (PDRC) is emerging as a promising cooling technology. Owing to the high, broadband solar reflectivity and high mid-infrared emissivity, daytime radiative cooling materials can achieve passive net cooling power under direct sunlight. The zero-energy-consumption characteristic enables PDRC to reduce negative environmental issues compared with conventional cooling systems. In this review, the development of advanced daytime radiative cooling designs is summarized, recent progress is highlighted, and potential correlated applications, such as building cooling, photovoltaic cooling, and electricity generation, are introduced. The remaining challenges and opportunities of PDRCs are also indicated. It is expected that this review provides an overall picture of recent PDRC progress and inspires future research regarding the fundamental understanding and practical applications of PDRC.
被动式日间辐射冷却（PDRC）正成为一种很有前景的冷却技术。由于具有高宽带太阳能反射率和高中红外发射率，日间辐射冷却材料在直射阳光下可实现被动净冷却功率。与传统冷却系统相比，零能耗特性使PDRC能够减少负面环境问题。在这篇综述中，总结了先进的日间辐射冷却设计的发展，突出了近期进展，并介绍了潜在的相关应用，如建筑冷却、光伏冷却和发电。还指出了PDRC面临的剩余挑战和机遇。期望这篇综述能提供PDRC近期进展的全貌，并激发未来关于PDRC基本理解和实际应用的研究。
