IV Measurement Software

TS-Space Systems offers a complete IV measurement system based on the Keysight B2900 series source-measure unit with control software built in Labview (software ships and runs with the Labview Runtime engine). The system is computer-controlled over a USB interface with all the settings accessible through the screen. The data is presented on the screen with the option for saving to disk and exporting to Microsoft Excel.

The software is able to conduct the following under illuminated IV test conditions:

• Measure cell Voc and Isc
• Select either manual or auto sweep setting
• Sweep volts and measure current
• Sweep current and measure volts
• Vary the integration and settle time for measurements
• Vary the number of sweep steps
• Graphically display multiple IV plots of measured volts and amps sweeps
• Graphically display power-voltage plots of an active IV sweep by mouse-over of desired plot)
• Calculate cell characteristic parameters:
  • Voc
  • Isc
  • Jsc
  • Pmax
  • VPmax
  • IPmax
  • Eff%
  • FF%
• Save all calculated parameters and sweep data to tab-delimited measurement file
• Load previous IV curves for comparison.
• Export measurement file to Microsoft Excel.

The software also provides a Dark IV sweep facility to:

• Export selected sweep data to Dark IV Analysis Excel worksheet
• Extract shunt and series resistance via curve fitting provided within the Excel worksheet

A temporal stability app is also included which allows real-time measurement of the light source's temporal stability.
