This is a video of my 2012-2013 Science Fair project. It shows how copper solar cells were made for my experiment. In this part of the experiment, copper was heated on high for 15 minutes and cooled for 30 minutes. During the heating time, cuprous oxide formed on the copper. After that, a layer of black cupric oxide formed on top of the cuprous oxide. As the copper cooled, some of the cupric oxide flaked off, revealing light orange cuprous oxide underneath. This cuprous oxide was used to convert light energy to electricity in my solar cells.
