The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
The first generation of the solar cells, also called the crystalline silicon generation, reported by the International Renewable Energy Agency or IRENA has reached market maturity years ago . It consists of single-crystalline, also called mono, as well as multicrystalline, also called poly, silicon solar cells.
In solar cell fabrication, crystalline silicon is either referred to as the multicrystalline silicon (multi-Si) or monocrystalline silicon (mono-Si) [70–72]. The multi-Si is further categorized as the polycrystalline silicon (poly-Si) or the semi-crystalline silicon, consisting of small and multiple crystallites.
Solar cells made from multi-crystalline silicon will have efficiencies up to ~22%, while 25% single junction monocrystalline silicon solar cells have been made from electronic grade silicon. Above 1414 °C, silicon is liquid. While crystalline silicon is semiconducting, liquid silicon is metallic and very reactive with air.
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.
