Dynamic photoluminescence lifetime imaging of multicrystalline silicon bricks

We apply the approach of dynamic photoluminescence lifetime imaging to a multicrystalline silicon brick. The dynamic approach allows the calibration-free determination of the bulk carrier lifetime of silicon bricks prior to wafer sawing. Using an indium gallium arsenide camera, we determine the bulk...
