- Summary:
- This report describes work to advance the manufacturing line capabilities in crystal growth and laser cutting of Mobil Solar`s unique edge-defined film-fed growth (EFG) octagon technology and to reduce the manufacturing costs of 10-cm × 10-cm polycrystalline silicon EFG wafers. The report summarizes the significant technical improvements in EFG technology achieved in the first 6 months of the PVMaT Phase 2 and the success in meeting program milestones. Technical results are reported for each of the three main pregrain areas: Task 5 -0 -- Thin octagon growth (crystal growth) -- to reduce the thickness of the octagon to 200 microns; Task 6 -- Laser cutting-to improve the laser cutting process so as to produce wafers with decreased laser cutting damage at increased wafer throughput rates; and Task 7 -- Process control and product specification --to implement advanced strategies in crystal growth process control and productivity designed to increase wafer yields.
