Description (Brief)
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 has an anti-reflection coating of titanium dioxide. The dark areas convert sunlight into electricity while the thick and thin lines are part of the electrical circuit. The silver, crescent-shaped main lead runs along one edge and gathers the charge from fourteen thin “fingers” that run horizontally across the wafer. This solar cell was designed for use on the ground rather than in space.
