A new type of solar panel capable of producing electricity at night has been developed. Researchers at Stanford University have created a photovoltaic (PV) cell that uses a process called radiative cooling to enable the production of renewable energy 24 hours a day. This system works by exploiting the heat radiated by the surface of the solar cells in the form of infrared light in space on a clear night. Researchers hope to provide a reliable, clean source of energy for the 750 million people around the world who currently live without electricity.
