Title: Continuous ribbon strip crystal - has carrier body to carry layer of substance through melting zone and draw=off as ribbon
Inventor: THIEME WOLFGANG DR ING
IPC: C30B29/64
Filed: 1991-07-04
Abstract: To draw virtually continuous ribbon strip crystal material from a melting zone, such as the basis for solar cells, the mantle of a rotating carrier body is continually coated with a supply substance.
