Abstract : A novel method and device for accurately aligning a substrate comprising a silicon wafer in the fabrication of a silicon vertical junction solar cell are described which comprise a base plate having a recess therein defining an opening for snugly receiving the wafer, the recess including a substantially straight portion for mating with a cleaved edge of known crystallographic orientation provided on the wafer, and a mask plate for covering the base plate and wafer, the mask including a pattern in predetermined configuration through which the wafer may be exposed in the fabrication process for the solar cell.
