Researchers from Austria's Vienna University of Technology (VUT) developed a new solar panel structure that results in an efficient, ultra-thin, flexible, transparent and durable panel. The new structure is made from two three-atomic-layers thick films with a layer of graphene in the middle.

The first film is made from a crystal tungsten diselenide, and the second film is molybdenum disulphide. In this design, the tungsten-diselenide layer is the one responsible to convert light into electrical energy. Normally using this material requires numerous tiny metal electrodes, but adding the molybdenium disulphide layer solves this issue.
