When sunlight strikes a solar cell, electrons in the silicon are ejected, which results in the formation of “holes”—the vacancies left behind by the escaping electrons.
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. This is done by heating the raw materials in a special furnace, yielding molten silicon that can be further processed into monocrystalline silicon wafers for certain solar cells.
