A January 30, 2024 Nature Communications paper investigated protective layers for thermochromic perovskite windows. The design admits water vapor needed for switching while limiting moisture damage. The team also demonstrated the coating on flexible PET film.
The study reported retained solar modulation during a 45-day aging test and reduced haze compared with an unprotected reference. Neither result provides a service-life rating or a guarantee of a clear view.
The protected material released less lead during an immersion test, but it still contains lead. Reduced leakage does not establish safe handling or disposal under every condition.
Building-energy benefits were modeled, rather than measured in an occupied installation. This is a possible protection strategy for future films. A commercial product would still need its own installation, environmental and durability evidence; the paper is not a product launch.
