Rooftop solar window based on semi-transparent perovskite solar cells
Researchers from the U.S. Department of Energy's Argonne National Laboratory have demonstrated a prototype solar-powered rooftop smart window based on an optimization algorithm capable of balancing a building's temperature demands and lighting needs.
The device is described as an energy-harvesting smart window built with semi-transparent lead-halide perovskite solar cells and multi-layer photonic structures and assembled with layer-by-layer spin coating. 'The lead-halide perovskite was chosen because of its capability of using a wide spectrum of sunlight and its simplicity in maintaining visible light transparency,' the team wrote.
