Abstract
A method of producing a sheet of semiconductor material directly usable for the production of solar cells is disclosed. The method comprises establishing a molten region at an edge of a sheet of semiconductor material, moving the molten region across the sheet to create a path of elongated crystal grains, establishing a molten zone along a portion of the path of the elongated crystal grains and parallel thereto, and causing the molten zone to travel in a direction transverse to the path of elongated crystal grains.
