Abstract
An apparatus for producing a polycrystalline silicon sheet includes a crucible, a heating unit for heating a starting material of silicon fed in the crucible, and a cooling unit for contacting a melt of the starting material melted by heating to a cooling face of a cooling member, thereby obtaining a polycrystalline silicon sheet in which crystals of silicon are grown, wherein the cooling face of the cooling member has a sheet adhering portion for providing a silicon starting point of crystallization and allowing adhesion of the polycrystalline silicon sheet of grown crystals and a sheet stripping portion for allowing easy stripping of the polycrystalline silicon sheet.
