Photovoltaic Cells: Common Power Source For Tomorrow?
The word "photovoltaic" combines the scientific terms "photo", meaning light, and "voltaic", meaning voltage. Together, the terms mean voltage generated by light energy. Specially treated silicon, or another substance, is manufactured in such a way that when light strikes it electricity is produced. The cells have no moving parts, and they are durable. They are commonly called solar cells.
