Solar Cell I-V Test System (Manual)

10. Test Device

The system is shipped with a test device with 100 kΩ resistors that can be used to check the
calibration of the system. They are arranged in the geometry of the substrate pixels, and the
appearance of the test device will depend on the substrate system being used (Figure 10.1).

10.1 Taking a Measurement

1. Plug in and switch on the system.
2. Allow at least 30 minutes for the system to warm up.
3. Place the test device in the device holder with the resistors or photodiodes facing upwards.
4. Start the Solar Cell I-V software and enter the settings in Figure 10.2.
I. These settings can be used with any current range except for the 20 μA range. For
this range the start and end voltages must be lowered to -2 V and 2 V respectively.
II. The 'Pixels to Measure' checkboxes should match the device configuration you
have.

7. To check the calibration of the system, use the I-V data to calculate the measured
resistance at -10 and 10 V (-2 and 2 V for the 20 μA current range).
