This Standard was technically approved by the global Photovoltaic Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on September 12, 2011. Available at www.semiviews.org and www.semi.org in October 2011.


This Specification covers the requirements for silicon wafers for use in photovoltaic (PV) solar cell manufacture. To permit common processing equipment to be used in multiple fabrication lines, it is essential for the wafer dimensions to be standardized.


This Specification provides standardized dimensional and certain other common characteristics of silicon wafers based on currently widely used sizes for photovoltaic applications.


This Specification also provides a tabular specification format for order entry so that relevant nonstandardized wafer characteristics and extensions of wafer sizes for research, development, and new requirements can be easily and consistently specified in commercial transactions.
