Build Your Own Solar PV Cell

Solar PV, or photovoltaic, panels convert electricity from sunlight into electricity. They consist of many individual solar cells, wired together to improve their performance. Solar cells, which are produced for commercial production, created from specially prepared silicon wafers and glass.

This process can be difficult and expensive for an amateur to replicate at home. However, you can build different, simpler, albeit less efficient a home other materials for science-fair project. Wash your hands to remove dirt and grease.

Scrub two small copper sheets with sandpaper to remove thin layer of oxides that coat any metal that is in contact with air. Put one of copper sheets onto burner of electric stove. Turn burner to its highest setting and let it heat up.

It will first turn orange, red and purple, and then finally black. black substance is cupric oxide. Heat sheet for 30 minutes after it has turned black in order to thicken coating of cupric oxide.

Turn off burner and let copper sheet cool to room temperature. As it cools it will shed much of cupric oxide that had formed. Once it is cool, scrub it gently under running water to remove rest of cupric oxide.

It is better to leave some black spots than scrub too hard. sheet should now have reddish color, which is cuprous oxide. It reacts to sunlight much as silicon of commercial cells does.

Cut plastic bottle in half with knife. Gently bend both of copper sheets so that they can fit into bottle. Put them in bottle in such way that they do not touch each other.

Pour about 1 liter of hot water into measuring cup. Slowly pour salt into water, mixing as you pour. Once salt stops dissolving, water is completely saturated.

Pour this salt solution into bottle with copper sheets. Leave about inch of sheets protruding above water.
