Forward-looking: Traditional solar power cells are based on a silicon semiconductor compound, which is known to have a theoretical maximum efficiency of 29 percent in converting sunlight into electric energy. However, by incorporating a second perovskite layer onto the base silicon layer, solar cells have the potential to surpass this efficiency threshold in the near future.
Forward-looking: Dye-sensitized solar cells (DSCs) are cheap, transparent, and flexible. The promising technology set a new record in efficiency for turning visible light into electric energy, making it viable for use as energy-collecting windows.
