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.

How thick should a crystalline silicon layer be in a solar cell?

One of the parameters controlled during the fabrication of solar cell is the thickness of one or another layer of the structure ( , pp. 3519–3520).
