Homemade solar cell using household items (update)

Question: can someone make a solar cell at home using household items?

Answer: yes you can using some very unusual items that are found around the house.

Solar panels are great for producing clean electricity, the only problem is the cost to buy one can be in the thousands, and the cheaper ones barely produce any electricity. Today I will be showing you how to build your own solar cells at home using some interesting materials that you can get from your local store or on the internet.

The solar cell that I made produces about 1volt, with 2 of these you could be able to light an LED, and with 5 you could even charge your device, I mean how cool is that. The glass that I used to make this was from an old microscope that I had that came with some glass slides that came with the kit. If you decide that you want to make this you don’t have to use glass slides, any size piece of glass work just for larger pieces you may need to take some wire and lay it across the panel to cover more surface area, the bigger the cell the more electricity it will produce.

For the best result make sure that you clean the foil off, along with the glass to ensure that the chemicals can make good contact with the foil, and to ensure that light can pass through the glass. The aluminum foil I found can rip easily so for my next one I will use two strips of aluminum from a pop can after sanding the paint off, these new connections would be stronger so be white to use pop can strips instead of aluminum foil.
