The solar cell is thus an n + pp + structure, all made of crystalline silicon (homojunction solar cell) with light entering from the n + side. At the front (n + region), the donor concentration N D falls steeply from more than 10 20 cm −3 at the surface to values below N A in a depth of less than 1 μm.
Silicon Solar Cells. The vast majority of today''s solar cells are made from silicon and offer both reasonable prices and good efficiency (the rate at which the solar cell converts sunlight into electricity).
