METHOD FOR PRODUCING CRYSTALLINE SILICON INGOT

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a crystalline silicon ingot having low bulk defect density at a bottom part of the ingot, and having small silicon particles.

SOLUTION: This invention provides a method for producing a crystalline silicon ingot. The method utilizes a nucleation promotion layer 2 to facilitate a plurality of silicon particles 34 to nucleate on the nucleation promotion layer 2 from a silicon melt 32 and grow in a vertical direction until the silicon melt 32 is solidified to obtain the crystalline silicon ingot.
