AI Customer ServiceThe 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.
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.
For silicon solar cells, the basic design constraints on surface reflection, carrier collection, recombination and parasitic resistances result in an optimum device of about 25% theoretical efficiency. A schematic of such an optimum device using a traditional geometry is shown below.
Material Characteristics: Essential materials for solar cells must have a band gap close to 1.5 ev, high optical absorption, and electrical conductivity, with silicon being the most commonly used.
However, silicon's abundance, and its domination of the semiconductor manufacturing industry has made it difficult for other materials to compete. An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick.
