round photovoltaic cell with copper contacts
notes: label: Description (Brief)
content: Solar cells come in many shapes and sizes, and are manufactured with a variety of materials. The wafer of this round cell is made with the element silicon and the circuit is made with copper. The dark areas convert sunlight into electricity while the thick and thin lines are part of the electrical circuit. A single electrical-lead runs down the center on the front of the wafer, stepped in three different widths and connects to nineteen thin copper fingers that gather the charge.
