7 Interpreting Measured I-V Curves

4. Rounder knee
An example of this type of deviation is shown below.
Figure 64. I-V curve measurement showing rounder knee than predicted by the PV
model.
Rounding of the knee of the I-V curve can be a manifestation of the aging process.
Before concluding that this is the case, check the slopes of the horizontal and vertical legs
of the I-V curve. If they have changed, it can produce a visually similar effect in the
shape of the knee.
