  9. A Carbon-Based Solar Cell 2D-Graphene 1D-Carbon Nanotubes • Strongest material known • Carbon nanotubes are 300 times stronger than steel. • Exceptional electronic properties • Grow metallic and semiconducting. • 1000 times more conductive than copper. • We can use carbon nanotubes to absorb light and generate electricity!

  10. How do the Layers in a Solar Cell Work? Raspberry/TiO2 Material Function Carbon Nanotubes C60 Ash Charge Extraction Juice Light Absorber CNTs - - TiO2 + Charge Extraction Glass Glass + Electrode
