(SSIVT-21C) Current-Voltage Measurement System (IV Tester) - 20W Version for Continuous Solar Simulators

The SSIVT is a complete electrical current-voltage (I-V) measurement system used to characterize photovoltaic cell performance. This current-voltage tester works by sampling current at different voltages of the photovoltaic cell with a variable impedance load. The system can generate I-V curve of samples like Solar cells.

This I-V Measurement System has a 4 wire Kelvin configuration to remove the resistance effects of the leads and bias the cell at specific voltages.

The I-V Testing Measurement System SSIVT-21C includes:

A) Keithley SMU Model 2401
-Power: 20 W
-Max Voltage: 20V
-Current Range: 1A

B) Sciencetech's SciPV-IV Software for Windows-based control.
Windows 7/10 32/64 bit

C) RS232 to USB dongle

The SSIVT-21C works with all Sciencetech Steady-State Solar Simulators.


Compatible with Steady State (Continuous) Solar Simulators only. Do not use the SSIVT-21C measurement system with flash solar simulators – it is not compatible with them (because it uses a Keithley 2401).
