Abstract

The generation of low-cost electrical power with the aid of silicon solar cells necessitates among others a substantial cost reduction of the silicon basic material required. A decisive step towards this aim is a recently developed method for crystallizing silicon which makes it possible to abandon the conventional ways of growing single-crystals. Some variations of this new process, which mainly consists in directed freezing of a silicon melt (casting in blocks and subsequent cutting, or casting in plates), is described in this paper.

The structure of the material is described as well as some properties, characteristical to its application in solar cell production, i. e. the columnar structure of large polycrystalline silicon slices, exhibiting monocrystalline arrangements of different orientations between the surfaces.
