Step By Step Instructions for Building Your Own Homemade Solar Cell
• Step 1: Cutting the copper sheeting
First you’ll need to take your metal shears and cut two equal sized pieces of the copper sheeting. The pieces should be no larger than your burner so you can ensure that the entire piece of copper is heated thoroughly and equally.
• Step 2: Cleaning the copper
Now you will need to wash your hands and the piece of copper to ensure that it is free of grease and other contaminants. You should only touch the copper sheet with gloves from this point on. After washing the sheet of copper, you need to take the sandpaper or emery cloth and gently sand down the top layer of the sheet to ensure it is completely free of any debris or contaminants.
