Several months ago, the team including Thomas Mueller, Marco Furchi and Andreas Pospischil, had already produced an ultra-thin layer of the photoactive crystal tungsten diselenide. Now, the semiconductor has successfully been combined with another layer made of molybdenum disulphide, creating a designer-material that may be used in future low-cost solar cells. With this advance, the researchers hope to establish a
