Metamaterial-Based Radiative Cooling: Towards Energy-Free All-Day Cooling
Energies, 2018 In the light of the ever increasing dangers of global warming, the efforts to reduce energy consumption by radiative cooling techniques have been designed, but are inefficient under strong sunlight during the daytime. With the advent of metamaterials and

Advanced Functional Materials, EarlyView.Photothermal, macroporous lignin‐based cryogels are engineered to convert sunlight into low‐grade heat. Integrated as stacked beds in a drum‐type device, a thin copper interlayer transfers waste heat between beds, enabling interlayer heat recovery and continuous solar cycling.

Simple dual-layer emitter for daytime radiative cooling
OSA Continuum, 2021 This work experimentally demonstrates a simple dual-layer emitter, which is easy to prepare and can be applied to effective daytime radiative cooling. The emitter consists of a 200-µm-thick polydimethylsiloxane film on top of a 120-nm-thick Ag film, which is coated on a fused silica wafer or a plastic substrate.
