How a Solar Cell Works. Solar cells contain a material that conducts electricity only when energy is provided—by sunlight, in this case.

To make a silicon solar cell, blocks of crystalline silicon are cut into very thin wafers. The wafer is processed on both sides to separate the electrical charges and form a diode, a device that allows current to flow in only one direction. The diode is sandwiched between metal contacts to let the electrical current easily flow out of the cell.
The first step in making any silicon solar cell is to extract the naturally occurring silicon from its hosts – often gravel or crushed quartz – and create pure silicon.
