Introduction

• Solar power is sunlight that is turned into
  electricity
• World usage 85 million barrels of oil per day
  (2007)
• Sun provides 120,000 TW
• Worlds currently usage is 15TW
• Silicon cell 2.5/w
• 37.5 trillion
• Need cheaper solar cells
• Dye cells

Conclusion

• The world still needs a cheaper source of an
  alternative use of energy
• Food dye might not be the most sustainable
  material to use in the cell
• Further research needs to be done to find other
  materials that will be strong enough to absorb
  more of the suns energy
