miniSMU App
Powerful, intuitive companion app
The included miniSMU MS01 companion application is the fastest way to get up and running performing a wide range of important measurements for solar cells, LEDs, transistors, and more.
Stability Features
Long-Term Stability Testing
Monitor solar cell performance over extended periods with our 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 be used to perform simultaneous stability experiments, maximising your research efficiency.

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.
