Precautions: |
|||
1.Do NOT touch the filters or the filter tray which has glass diffuser glued into it, with bare |
|||
hands. Use gloves or tissue paper for the same. |
|||
2.Make sure that the filter tray/flash mount assembly does NOT fall down while sliding it over the flash tower for adjusting height of the flash. |
|||
3.Ensure that the BNC cable and flash trigger connections are in place based on the measurement to be done i.e. to lifetime tester stage or Suns VOC stage. |
|||
4.Note down the height of the flash from the stage, the setting on the flash (1/1 or 1/64) and the filter being used during measurement. Different users tend to change this according to their requirements. |
|||
5.Make sure that the reference cell is NOT covered during the measurement. |
|||
6.Do NOT start the measurement on Lifetime tester until it is thermally stabilized i.e. Red LED is OFF. |
|||
7.During chemical passivation, ensure that solution does NOT spill on the stage. |
|||
8.For Suns VOC measurement, ensure that sample consists of P-N junction and both P N sides can be probed properly. |
|||
9.Ensure that proper action is taken for addressing error messages in the measurement:i.Saturated reference cell: Height of the flash is adjusted to change the intensity of light to avoid saturation of reference cell.ii.Min MCD < Specified MCD < Max MCD: Change the specified minority carrier density to fit in the measured range of minority carrier density.iii.Remove the sample on lifetime tester stage during zeroing of the instrument: No sample in the vicinity of stage during zeroing of the instrument. |
|||
10.Ensure that SUMMARY file is NOT cut pasted during the data transfer: |
