Scientists Create Gorgeous Nanoflowers for Next-Gen Solar Cells and Ultra High-Density Energy Storage

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.
North Carolina State University  created its GeS nanoflowers by heating germanium sulfide powder in a furnace until it begins to vaporize. Once airborne, the particles are blown into a cooler part of the furnace, where they settle onto a layered sheet that is about 20-30 nanometers thick and 100 nanometers long. As more layers are added, the sheets begin to branch away from one another, forming a structure that looks like a flower.
GeS is inexpensive and non-toxic, making it a desirable choice for use in solar cells . In addition to being an efficient material for capturing light and converting it into usable energy, GeS could also potentially extend the capacity of lithium-ion batteries and provide increased storage for supercapacitors.
