Advanced Czochralski silicon growth technology for photovoltaic modules [PDF]

open access: yes
Several economic analyses had indicated that large-diameter, multiple ingot growth using a single crucible with melt replenishment would be required for Cz growth to be economically viable. Based on the results of these analyses, two liquid and two solid
