Abstract

I will introduce our research progress of the electrochemical tuning device that can dynamically switch between solar heating and radiative cooling. The solar and mid-IR dual-band synergistic tuning results in wider heat management capability for a broad range of thermal environments. In particular, this device can be used as smart building envelopes for all-weather, year-round HVAC energy saving. I will introduce the key challenges and our innovations of the device, including the ultra-wideband transparent electrode, reversible metal electrodeposition, plasmonic nanostructure evolution, and device configuration optimization. In addition to synergistic multispectral dual-band tuning between solar heating and radiative cooling, the device also shows >0.85 mid-IR emissivity contrast, leading to profound performance for space or military applications.
