Perovskite is the word of the week! This trailblazing new material is being used in cheaper, highly efficient photovoltaics. Commercial silicon-based solar cells (the kind you see on roofs) convert the sun’s rays into electrical energy at about 20 percent efficiency -- and it took two decades of...
