Although there are other types of solar cells and continuing research promises new developments in the future, the crystalline silicon PV cell is by far the most widely used. A silicon photovoltaic (PV) cell converts the energy of sunlight directly into electricity—a process called the photovoltaic effect—by using a thin layer or wafer of silicon that has been doped to create a PN junction.
