There
exists a need in the silicon wafer industry for methods of
non-contact and non-destructive in-line monitoring of wafer defects
such as residual stress and cracks. Vibrations and acoustics are
being used to develop such diagnostic tools for assessing these
types of defects. Application of these tools to solar cells is
shown.
