Scientists at NREL (the US Department of Energy’s National Renewable Energy Laboratory) have presented a perovskite-based solar window that gets darker the sunnier it is and has a conversion efficiency of 11.3%. The window drives out methylamine molecules when it is exposed to sunlight, darkening the glass, and absorbs them as it cools back down.
