Description (Brief)
Solar cells come in many shapes and sizes, and are manufactured with a variety of materials. The wafer of this hexagonal cell is made with the element silicon. The dark areas convert sunlight into electricity while the thick and thin lines are part of the electrical circuit. The white, tapered arrow along the center is the main lead and gathers the charge from twelve thin “fingers” that run horizontally across the wafer. This solar cell was designed for use on the ground rather than in space. The hexagonal shape allows many cells to be grouped together on a panel, minimizing wasted space between each cell.
