How is a solar cell constructed
Web24 jun. 2024 · The cells are constructed by stacking semiconductors with varying bandgaps on top of one another, thereby allowing the cell to absorb differing wavelengths of solar radiation. However,... WebThe 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. At the rear (p + region), the silicon ...
