Electric Blue Leather Keyring

NANOVIZZ

  • Polycrystalline silicon solar cell. This photovoltaic cell converts light into electrical energy, and is a clean, renewable source of energy. The cell is made from a semiconducting silicon nitride wafer (blue), covered by a grid of electrodes (white), made of silver nanoparticles, which collect the electrical current generated by the wafer. Polycrystalline (multiple crystal) cells are less efficient than monocrystalline (single crystal) cells, but are far cheaper to manufacture. Imaged with light microscopy
