Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power.
Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding.
Scrub the completely cooled copper under running water to remove any last remaining bits of oxide. Be gentle, as you do not want to remove any of the red cuprous oxide that has been created in heating the flashing.
Make a solution of salt and water by dissolving the salt in hot tap water. You should make enough solution to barely cover the bottom of the plates, leaving the clips high and dry.
