Revolutionary Triple-Layer Smart Windows: Durable, Moisture-Transmitting, and Haze-Free

• Introducing the groundbreaking MTPW: a triple-layer thermochromic perovskite window inspired by medical masks. With enhanced durability and optical clarity, it's perfect for sustainable green buildings.

Researchers from City University of Hong Kong, Zhejiang University, and The Hong Kong University of Science and Technology have developed a triple-layer thermochromic perovskite window (MTPW) that can transmit moisture while repelling water and extending its lifespan. The design was inspired by the structure of medical masks. The MTPW addresses the challenges of poor durability and optical blurriness faced by thermochromic perovskite smart windows. It demonstrated superhydrophobicity, maintained a solar modulation ability above 20% during a 45-day aging test, and significantly reduced lead leakage. The MTPW's improved optical performance and extended lifespan make it suitable for use in green buildings.

How does the triple-layer thermochromic perovskite window address durability and optical blurriness challenges?

• The triple-layer thermochromic perovskite window (MTPW) addresses the challenge of poor durability faced by thermochromic perovskite smart windows.
• The MTPW design was inspired by the structure of medical masks, which allows it to transmit moisture while repelling water.
• During a 45-day aging test, the MTPW maintained a solar modulation ability above 20%, indicating its long-lasting performance.
• The MTPW demonstrated superhydrophobicity, meaning it has the ability to repel water and prevent water damage.
• The MTPW also significantly reduced lead leakage, making it a safer and more environmentally friendly option.
• The improved optical performance of the MTPW ensures that it does not cause optical blurriness, providing clear visibility through the window.
• The extended lifespan of the MTPW makes it suitable for use in green buildings, where durability and longevity are important factors.
• The MTPW's ability to address both durability and optical blurriness challenges makes it a promising solution for the development of more efficient and sustainable smart windows.
