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 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.
As one of the PV technologies with a long standing development history, the record efficiency of silicon solar cells at lab scale already exceeded 24% from about 20 years ago (Zhao et al., 1998).
An essential prerequisite for the growth of crystalline silicon from the raw materials is the availability of silicon of the highest purity attainable. 17 Impurities or defects in the single crystals can lower the performance of the solar cell device due to recombination of charge carriers.
Solar cells that are available on the market are mainly “Generation I” devices, made out of crystalline silicon (c-Si). The fabrication of c-Si based devices is a well-developed and established technology.
This section will introduce and detail the basic characteristics and operating principles of crystalline silicon PV cells as some considerations for designing systems using PV cells. A PV cell is essentially a large-area p–n semiconductor junction that captures the energy from photons to create electrical energy.
