Special Announcements of the Committee (Workshops, Programs, etc.)
SEMI, Solar America Board of Codes and Standards (ABCs), Arizona State University (ASU), and Department of Energey (DOE) are organizing a workshop on Crystalline Silicon Terrestrial Photovoltaic Cells – Supply Chain Prequalification Specifications at Polytechnic Campus in May 13, Mesa, Arizona. This workshop will also include tours at ASU-TUV Rheinland and AAPS STAR PV testing facilities. This whole day workshop is free. For registration and further information, please visit us.

Standards Technology Group (STG) and SEMI are organizing a course on SEMI PV Standards - Equipment Performance and Communications during Intersolar America, July 14-16 in San Francisco. This course is being planned for Tuesday, July 15. For the latest details and agenda, please visit
