Researchers at the Karlsruhe Institute of Technology have developed a hybrid system that combines solar energy harvesting with passive daytime radiative cooling to provide electricity, heat, and cooling from a single surface. The system integrates photovoltaics with a transparent cooling layer that emits heat into space through the atmospheric window, achieving cooling of up to 6.5 C below ambient temperature while generating electricity and heat. The team plans to optimize the system for widespread use on roofs and facades to provide multifunctional energy solutions, showcasing a promising advancement in climate-friendly technology.
