The group of YIP Hin-Lap at South China University of Technology has constructed a glass device that let the familiar visible portions of sunlight through, turning back the infrared light, and converting the near-infrared region in-between into an electric current. In theory, installing windows outfitted with dual electricity-generating and heat-insulating properties could cut an average household’s reliance on external electric sources by over 50 percent. Applications of this technology to greenhouses are also foreseen.
