Dye-sensitized solar cells could make solar power more affordable: they are cheaper to make than conventional silicon solar cells and can easily be printed on flexible surfaces. But there’s a catch: creating efficient cells of this type has required dyes made of the precious metal ruthenium and volatile electrolytes. Now researchers at the Chinese Academy of Sciences have replaced both of these materials in a new kind of dye-sensitized solar cell that is not only highly efficient: it also promises to be even cheaper and more durable.
