A Rooftop Device That Can Make Solar Power and Cool Buildings

Stanford researchers develop a rooftop device that can make solar power and cool buildings A new rooftop device under development will be able to produce electricity from sunlight while also beaming heat directly into space to cool buildings. The novelty lies in the device’s bottom layer, which is based on materials that can beam heat away from the roof and into space through a process known as radiative cooling. Zhen Chen, who led the experiments as a postdoctoral scholar in Fan’s lab, said the researchers built a prototype about the diameter of a pie plate and mounted their device on the rooftop of a Stanford building.
