Can photovoltaic cells be measured in the dark?
Since solar cells convert light to electricity it might seem odd to measure the photovoltaic cells in the dark. However, dark IV measurements are invaluable in examining the diode properties. Under illumination, small fluctuations in the light intensity add considerable noise to the system making it difficult to reproduce.

What is the I-V characteristic of a photovoltaic module?
The I-V characteristic of a photovoltaic module subjected to a stressing current of 100 mA, presented on a logarithmic scale The reverse characteristic of the module is measured by applying a reverse voltage through the junction to verify that no current is flowing, a large current means that the module is broken and no more useful.
