Nov 4, 2023 · Though water itself does not absorb much light, and neither does the hydrogel material itself, when the two combine they become strong absorbers, Chen says. That allows the material to harness the energy of the solar photons efficiently and exceed the thermal limit, without the need for any dark dyes for absorption.
Apr 23, 2024 · The effect is strongest when light hits the water surface at an angle of 45 degrees. It is also strongest with a certain type of polarization, called transverse magnetic polarization. And it peaks in green light — which, oddly, is the color for which water is most transparent and thus interacts the least.

Apr 24, 2024 · “The finding of evaporation caused by light instead of heat provides new disruptive knowledge of light-water interaction. It could help us gain new understanding of how sunlight interacts with cloud, fog, oceans, and other natural water bodies to affect weather and climate,” enthused Xiulin Ruan, professor of mechanical engineering at Purdue University , who was not involved in the study.
Nov 1, 2023 · Photomolecular effect. A new study by researchers at MIT has revealed a surprising discovery: Light can directly cause water to evaporate faster without the need for heat.
Jan 5, 2024 · Under certain conditions, light can cause water to evaporate directly, without heating it first. The process works by cleaving water clusters from the water-air interface, and researchers at the Massachusetts Institute of Technology (MIT) in the US have dubbed it the “photomolecular effect” in analogy with the well-known photoelectric effect.
