Challenges and Opportunities for Passive Thermoregulation

Advanced Energy Materials, Journal Year: 2024, Volume and Issue: 14(34)

Published: June 26, 2024

Abstract The unsustainable nature of energy‐intensive and environmentally unfriendly traditional air conditioning systems, compacted with recent climate change effects, show an urgent need for more sustainable efficient thermoregulation solutions. Innovations in passive daytime radiative coolers (PDRCs) selective solar absorbers (SSAs), which utilize natural resources, the “cold” outer space “hot” sun from sky, offer friendly cost‐effective alternative. However, various factors significantly impede commercial viability these technologies, such as lack emphasis on advancements practical application, challenge reversible functionality between PDRCs SSAs, inconsistent performance evaluation, absence effective mass production strategies. Here current challenges future development trends PDRC SSA‐aided innovation are discussed. Specifically, opportunities relating to application conditions, evaluation parameter standardization, strategies considered large‐scale production, all critical realizing full potential SSAs.
