ABSTRACT:
Disclosed therein is an apparatus for producing a polycrystalline silicon ingot for a solar cell, which has uniform crystal grains formed by solidifying silicon melted in a crucible using a cooling plate. The polycrystalline silicon ingot producing apparatus includes: a crucible for melting silicon; conveying shafts for adjusting the height of the crucible; heaters for heating the crucible; and a cooling plate located below the crucible for cooling the crucible.
