Abstract:
The present invention relates to an apparatus and method for purifying materials using a rapid directional solidification. Devices and methods shown provide control over a temperature gradient and cooling rate during directional solidification, which results in a material of higher purity. The apparatus and methods of the present invention can be used to make silicon material for use in solar applications such as solar cells.

Claim (Index 8):
A mold for directional solidification, comprising: a substantially rectangular shaped wall structure, including a long side and a short side; a heat conducting base positioned to directly contact molten material, the base including a material of a higher thermal conductivity than a wall material, coupled to the substantially rectangular shaped wall structure; wherein the substantially rectangular shaped wall; and wherein the substantially rectangular shaped wall structure is positioned to directly contact molten material, and the rectangular shaped wall structure tapers in thickness from a rim of the mold, having a first thickness, to a bottom interface with the heat conducting base, having a second thickness that is thinner than the first thickness.
