摘要：
A base layer of a semiconductor material is formed with a naturally textured surface. The base layer may be incorporated within a photovoltaic structure. A controlled spalling technique, in which substrate fracture is propagated in a selected direction to cause the formation of facets, is employed. Spalling in the [110] directions of a (001) silicon substrate results in the formation of such facets of the resulting base layer, providing a natural surface texture.
