How Do You Make A Solar Cell Panel?
Ever want to do your own science experiments at home? You can demonstrate the principle of semiconductivity by creating your own solar cell panel. While this might not do much to light a lightbulb, it will produce measurable amounts of current using mostly common household items. Make sure that any children performing this experiment have adult supervision for the copper-cooking and soldering portions of the process. Cut a piece out of the copper flashing that’s just large enough to cover one of the burners on your electric stove without any overlap. Trim it, if necessary, to make sure that it will also fit inside the CD jewel case without overlapping. Turn one of the burners on your electric stove up to high. Once it’s red-hot, place the cutout copper sheeting on it and let it cook for half an hour. The copper should turn completely black. Switch the burner off and leave the copper on it to cool. Flakes of the black coating will fly off the copper, jumping as far as a couple of inches
