Chemically modified wood captures sunlight and stores it as heat

Apr 11, 2026 A layered coating on delignified wood enables solar heat storage and electricity generation without carbonization, while adding water, fire, and microbial resistance. (Nanowerk Spotlight) Photothermal conversion can in principle capture more than 90% of incoming solar radiation, far exceeding the roughly 25% ceiling that bounds conventional photovoltaics....
