摘要

As the production volumes of crystalline silicon manufacturing lines have grown in recent years, the demand for improved process control and process monitoring in manufacturing has increased. Since 1995, Sinton Consulting Inc. has been providing several tools to both Universities and industry for their R&D laboratories. For example, over 100 Sinton minority-carrier lifetime instruments are in use worldwide. The purpose of the work reported here is to adapt these successful R&D instruments and techniques to be directly applicable to process control and monitoring in production environments. Under the PV Manufacturing R&D subcontract Development of an In-Line, Minority- Carrier Lifetime Monitoring Tool for Process Control during Fabrication of Crystalline Silicon Solar Cells, Sinton Consulting developed prototypes for several new instruments for use in the manufacture of silicon solar cells. These instruments are based on two families of R&D instruments that were previously available, an illumination vs. opencircuit- voltage technique and the quasi-steady state RF photoconductance technique for measuring minority-carrier lifetime. Compared to the previous instruments, the new prototypes are about 20 times faster per measurement, and have automated data analysis that does not require user intervention even when confronted by challenging cases.
