Abstract
A mono-crystalline silicon growth method includes: providing a furnace, a supporting base and a crucible which do not rotate relative to the furnace, and a heating module disposed at an outer periphery of the supporting base. After solidifying a liquid surface of a silicon melt in the crucible to form a crystal, the heating power of the heating module is successively reduced to appropriately adjust the temperature around the crucible to effectively control a temperature gradient of a thermal field around the crucible, so as to form a mono-crystalline silicon ingot by solidifying the silicon melt.
