ABSTRACT:
Recrystallized silicon plates are readily removed from a carrier member after melting and recrystallization, the carrier member being composed of a material that is not appreciably wettable by molten silicon, through the use of a parting agent between the silicon and the carrier in solid form as a powder or a raw foil. Fine quartz sand, very fine grained silicon powder, or quartz glass fiber fabric can be employed as the parting agent. The method is employed for the inexpensive manufacture of self-supporting silicon crystal plates for solar cells and allows throughput drawing rates of greater than 1 m.sup.2 /min.
