Interaction of molten silicon with silicon metal oxynitride solid solutions

Considerable attention is being given to developing better methods of processing solar cells. These methods generally fall into one of two categories: (1) slicing and wafering of Czochrolski boules and (2) ribbon growth methods. In all of these processes, refractory materials are needed as crucibles to hold the molten silicon, and some of the ribbon processes also require a ceramic shaping die to form the silicon sheet
