PV02200 - SEMI PV22 - Specification for Silicon Wafers for Use in Photovoltaic Solar Cells

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 non-standardized wafer characteristics and extensions of wafer sizes for research, development, and new requirements can be easily and consistently specified in commercial transactions. This Specification covers ordering information and certain requirements for single crystal silicon wafer and cast silicon wafer for PV applications.   This Specification allows growth methods that include Czochralski (Cz) method, Floating Zone (FZ) method for single c
