miniSMU AppMeasurement software for Windows, macOS and Linux
The included companion application is the fastest way to get up and running with measurements on solar cells, LEDs, transistors, and more.
What's new in v1.4.1Stability Features
Long-term stability testing
Monitor solar cell performance over extended periods with the I-V Stability feature. Track crucial performance parameters like Voc, Jsc, FF, and PCE as they evolve over time.
- Automate repeated I-V sweeps at customisable intervals
- Visualise performance trends with real-time parameter graphs
- Run experiments for hours, days, weeks, or longer
- Essential for degradation studies and reliable device characterisation
Both miniSMU channels can run simultaneous stability experiments, maximising your research efficiency.
The app in action
Real-time Data Logging
Monitor voltage and current over time with our dual-channel logging capabilities. Perfect for tracking sensor output over time.
Maximum Power Point Tracking
Track the maximum power point of your solar cell in real-time. Our perturb and observe algorithm continuously optimises power output, monitoring performance variations as conditions change.
I-V Curve Measurement
Perform I-V sweeps with real-time curve plotting. Essential for characterising solar cells, LEDs, and other electronic components with precision and clarity.
IDS-VGS Transistor Sweep
Characterise transistors with drain-source current vs. gate-source voltage sweeps. Analyse MOSFET behavior across different operating conditions with ease.
Gate-Source Transfer Characteristics
Examine transistor gate-source transfer behaviors with our specialised sweep function. Extract threshold voltage and other key parameters automatically.
