3  Background

PV04000 - SEMI PV40 - Test Method for In-Line Measurement of Saw Marks on PV Silicon Wafers by a Light Sectioning Technique Using Multiple Line Segments StdTpc-Silicon Both constant-current and constant-voltage TDDBSilicon (Si) wafers for PV applications cut from a Si ingot or Si brick contain a variety of micro and macroscopic crystallographic defects and flaws that may impact the efficiency of a solar cells or the yield of a manufacturing line. Theses defects can be categorized by their origin, either as grown in defects that are generated during the solidification of the Si ingot or as process induced defects that are generated by abrasive processes during
