Photovoltaic cells, or solar cells, are the devices that make use of sunlight to create electricity. They use the photovoltaic effect, which is a physical and chemical phenomenon in which electrons move between two different materials when exposed to light. This movement of electrons creates an electric current and voltage within the cell.
In this chapter, the working mechanism for traditional silicon-based solar cells is first summarized to elucidate the physical principle in photovoltaics.
