Homemade Solar Cells Are Easy To Make | Wind And Solar

by Aggie Montana

Solar cells are used for converting the solar energy into the electric energy. These cells can be bought from the market easily for the commercial use or large scale use. They can also be made at home with the help of simple equipment. These homemade solar cells can be useful for understanding the principle of solar cells. They can also be used for powering the low voltage electric appliances.

Making a solar cell at home generally requires material which is easily available at home and that too in the kitchen. Even if some of the things are not found in your kitchen, you can take a walk to the neighborhood hardware store.

When making the solar cells at home, using cuprous oxide seems a better choice. Commercially, the silicon is used instead of cuprous oxide. In order to make a solar cell at home, you will need to have a copper sheet, a few clip leads, an electric stove, sand paper and a micro ammeter. All of these materials are easy to find.

Copper sheet taken is cut to fit the stove. Size of the sheet should be proper and it should not cover the entire burner. It should properly fit over the burner. After doing this you should clean your hands with soap. Now clean the copper by using sand paper or wire brush. This will result in removal of light corrosion.

Turn on the stove and place the piece of copper on it. Color pattern of copper will change with time. Keep the stove on until a black coating appears on the sheet. Now it is time to wait until copper cools down. With this cooling process, black coating will disappear and it will take half an hour.

Now place this sheet into an open jar. Cut another piece from the copper sheet of the same size and place it in the jar as well. Make sure that they are not touching each other. You may have to bend these pieces of copper in order to fit in the jar properly.

Make a solution of salt with tap water fill the jar with it. Jar should not be filled completely. Now use wires to connect ammeter to alligator clips. Take this assembly in the sunlight and current will start flowing. This is how homemade solar cells are made with a very simple and easy procedure.
