In terms of processing, solar cells based on n-type silicon show a slightly higher complexity and higher manufacturing cost, as both phosphorus for the BSF and boron for the emitter (the region of the wafer showing opposite doping from the bulk) 48 have to be diffused, and because both front and rear metal layers require silver-based pastes.
The first step in producing silicon suitable for solar cells is the conversion of high-purity silica sand to silicon via the reaction SiO 2 + 2 C → Si + 2 CO, which takes place in a furnace at temperatures above 1900°C, the carbon being supplied usually in the form of coke and the mixture kept rich in SiO 2 to help suppress formation of SiC.
