How to solder photovoltaic cells
Solar cells, also known as photovoltaic cells, are made from silicon, a semi-conductive material. Silicon is sliced into thin disks, polished to remove any damage from the cutting process, and coated with an anti-reflective layer, typically silicon nitride. After coating, the cells are exposed to light and electricity is produced.
