6 FAQs about [Solar Cell Silicon Material Metallurgy]
What is the metallurgy of a solar cell contact?
The metallurgy of the contact and its detailed behavior is surprisingly complex, especially in the case of the screen printing used for solar cells, depending on the silicon surface cleanliness, the composition of the paste, and the annealing or sintering of the contact after printing.
What percentage of silicon is used in solar cell production?

What is a silicon solar cell?
As microelectronics go, a silicon solar cell is a relatively simple device. In its most common form, the solar cell is comprised of a ∼0.3 mm thick wafer or sheet of silicon containing appropriate impurities to control its electrical properties.
What materials are used to make solar cells?
Although at least several hundred materials systems, including combinations of semiconductors, metals, oxides, electrolyte solutions, and organic molecules and polymers have been considered for solar cells, the vast majority of all commercial solar cells are made from silicon.
Why is CZ silicon a cheaper solar-grade silicon?
Ironically perhaps, the purity of the polysilicon produced by the chlorosilane process used to make silicon for Cz wafers far exceeds that needed for solar cells.
