Scientists from Nanjing University and the Chinese Academy of Sciences have developed a tandem system combining daytime radiative cooling with solar power generation. The system uses a transmission-type radiative cooling design integrated with solar cells, achieving a cooling power density of 40 W/m² and a photovoltaic power density of 103.33 W/m² in sunny conditions. With a solar cell power conversion efficiency of 11.42%, the system demonstrates potential for improving energy efficiency. Simulations suggest that enhancing heat transfer efficiency and reducing sunlight band absorptivity in the emitter can further optimize performance. This research offers a novel approach to combining cooling and solar energy technologies for practical applications.
