Why Its Cool

• Its Better, Faster, and Cheaper than
  conventional solar panels.

3
Better

• More versatile and durable than conventional
  solar panels
• Can be placed in many more places under more
  conditions.

4
Faster

• Printed like a newspaper instead of assembled
• Less time to install

5
Cheaper

• Costs less to manufacture and only 0.30/watt to
  produce electricity, versus 3/watt for
  conventional solar panels, and 1/watt for coal.
• Maintenance and installation costs are lower as
  well.

6
How Its Made

• The sheet is made of 5 layers in 3 easy steps
• An aluminum foil is pressed out for the bottom
  layer
• A thin layer of the element molybdenum is printed
  onto this foil layer
• Another press is used to cover it with 3 more
  layers consisting of a semiconducting ink, a P/N
  junction layer, and a zinc oxide electrode
  conducting layer.

7
How It Works

• Light passes to the middle semiconducting ink
  layer, which breaks up the electrons.
• The molybdenum on the fourth layer acts as an
  electrode, and as the end of the circuit.
• The second layer is a P/N junction, which
  conducts the electrons through to the top layer.
• The top layer conducts the electrons and work as
  the beginning of the circuit.

8
Uses

• Can be placed nearly anywhere
• Rooftops, Cars, Laptops, Cell Phones, etc.
• Help develop 2nd and 3rd world countries
• Its cheap, durable, and soon will be a
  plentiful source of electricity
