______ is the process of converting silicon into high-purity polycrystalline silicon for use in the production of photovoltaic cells.
Doping
Czochralski process
Thermal oxidation
Chemical vapor deposition
The process of converting silicon into high-purity polycrystalline silicon for use in the production of photovoltaic cells is called the Czochralski process. It involves slowly pulling a small seed crystal of silicon out of molten silicon while rotating it at a constant speed to form a highly pure cylindrical ingot.
