How Do You Make A Solar Cell At Home?
Solar energy is actually surprisingly easy to produce, so long as the electrical demand is not too high. A crude but workable cell can be made in any kitchen. This makes a homemade solar cell a fantastic school science project. It is easy, relatively cheap, truly educational and has a lot more panache than a lemon powered clock. Follow these steps. Examine the copper sheeting to make sure it is free of corrosion. If it is not, clean it or get a new sheet. Take the clean copper sheet and cut a square or rectangle from it.

Once it is red hot, it will need to stay that way for at least three minutes. A layer of black oxide should form on the surface. Use the tongs to remove the copper sheet once it has formed a layer of black oxide. It should take 20 minutes or more to cool properly. Do not handle it with your bare hands until it is properly
