Hysteresis I-V
•
Set whether to perform a reverse current-voltage measurement after the forward current-
voltage measurement has completed.

voltages and uses the same voltage increment
and settle time as the forward measurement.

Lifetime Parameters
Figure 9.8.
Lifetime Parameters settings.
(I)
Duration
•
Set the total duration in hours of the lifetime measurement.
(II)
Interval
•
Set the time interval in minutes between performing repeat current-voltage
measurements of the device.
(III)
Hold Voltage
•
Set the voltage that all pixels will be held at between measurements.
•
This can be set as:
I.
Short-Circuit
–
hold at 0 V.
II.
Maximum Power
–
hold at the average maximum power point determined from
most recent current-voltage curve.
III.
Open-Circuit
–
hold at the average open-circuit voltage determined from the most
recent current-voltage curve.
Note:
As the voltage source is a single channel, the hold voltage will be the same for all
pixels being tested.
