Abstract

The present invention relates to an apparatus for manufacturing silicon ingots, comprising: a chamber; a crucible installed in the chamber; a heating unit for heating the crucible; a crucible-mounting unit on which the crucible is placed; and at least two or more water-cooling rod groups arranged below the crucible-mounting unit, wherein said at least two or more water-cooling rod groups are spaced apart from each other about the crucible mounting unit and connected to respective water supply pipes.

Description

technical field [0001] The present invention relates to a silicon ingot preparation device, and in more detail, relates to a silicon ingot preparation device with solidified structure in <100> direction with good orientation by using individual water-cooled rods to control the solidification interface when the silicon ingot is solidified. Background technique [0002] With the recent rise of the problem of global warming, the development of new and renewable energy is actively proceeding. Among them, the solar industry has shown an average annual growth rate of more than 40% in the last five years due to its advantages of no pollution, preservation of energy resources, no remuneration, and high reliability. [0003] Currently, the supply of polysilicon, which is the basic raw material of solar cells, cannot be satisfactorily realized, and an inverted pyramid-shaped value chain appears. The price of polysilicon, which is a raw material, has risen due to the shortage of...
