Grätzel is a chemistry professor at the École Polytechnique Fédérale de Lausanne in Switzerland, and since now they didn’t have any commercial purpose, being developed just for research. The first company who is about to commercialize Grätzel’s cells is G24 Innovations, […]

They made copies of the butterflies' solar collectors, and transferred the light-harvesting structures to classic Grätzel (or dye-sensitized) cells.
