What Is a Solar Cell?
A solar cell is a device which converts light energy into electrical energy, they are sometimes called photovoltaic cells.
How do Solar Cells Work?
Photovoltaic cells are made of special materials called semiconductors such as silicon. Basically, when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely. Electricity is flow of electrons.
