PVMaT Cost Reductions in the EFG High Volume PV Manufacturing Line. Final Subcontract Report 5 August 1998-4 Febraury 2001

摘要

The 3-year PVMaT 5A2 program at ASE Americas addressed topics in three major task areas: manufacturing systems development; low cost processing technology, and flexible manufacturing methods. The objectives were as follows: decrease electrical and mechanical yield losses by 10% each; reduce chemical consumption and waste products in manufacturing by 10%; develop procedures for certification in ISO 9001 and ISO 14001; develop low damage, high speed laser cutting methods; evaluate wafer production from large diameter EFG cylinders and polygons with wafer thicknesses down to 95 microns; develop low damage, high speed laser cutting methods; investigate cell designs for less than15% cell efficiencies on 100 micron thick EFG wafers; develop Rapid Thermal Processing (RTP) for thin high efficiency EFG cells; develop and introduce flexible manufacturing methods for manufacturing floor diversifications in wafer size and module design; demonstrate new module encapsulants, designs, and manufacturing technologies; and develop Root-Mean-Cause-Of-Failure methodology for modules using field studies. Significant accomplishments in the program are presented.
