Abstract

A device is provided for producing a crystallized silicon body for solar cells. The device includes a reaction vessel, a silicon container arranged within the reaction vessel for containing a raw silicon material, an upper heater arranged above the silicon container for heating the raw silicon material contained in the silicon container, a lower heater arranged below the silicon container for heating the raw silicon material contained in the silicon container, and an insulator unit arranged inside the reaction vessel for surrounding the silicon container, the upper heater and the lower heater. The insulator unit is provided with a side insulator which includes a fixed side insulation member, a plurality of movable side insulation members coupled with the fixed side insulation member and a plurality of side actuators operatively connected to the movable side insulation members for moving the movable side insulation members toward or away from the silicon container.

Description

technical field [0001] The present invention relates to an apparatus for the production of crystallized silicon bodies for solar cells, and in particular to an apparatus for the production of crystalline silicon bodies capable of releasing the thermal insulation during the melting phase to allow heat transfer Maximum rate and increased melting rate, able to insulate the sides of the silicon container during the crystallization stage, but de-insulate the lower part of the silicon container to implement cooling in one direction and open the insulation space in the late stage of crystallization to shorten the cooling time and Facilitate the next production cycle. Background technique [0002] Generally, polysilicon ingots for solar cells are produced by filling a quartz or graphite furnace with silicon feedstock, melting the silicon feedstock into silicon liquid and directly solidifying the silicon liquid into polysilicon ingots. Since the demand for solar cells is rapidly inc...
