When it comes to capturing the energy of the sun, what better model is there than photosynthetic plants? Researchers at North Carolina State University have cultivated a beautiful crop of germanium sulfide (GeS) “nanoflowers” that could be used to create next generation solar cells and ultra high-density energy storage systems. The nanoflowers have petals that resemble those of a geranium or marigold – although they’re only 20-30 nanometers thick and they’re capable of storing much more energy than traditional energy storage cells.
