Why this service
What Solar I-V can help you understand
Solar-cell I-V testing sweeps voltage while current is measured under controlled illumination and, where selected, in the dark. Reliable performance metrics depend on calibrated irradiance, active area,…
Is hysteresis or series/shunt resistance limiting performance?
Dark and light J-V
How consistent are pixels, devices or ageing conditions?
Pixel, hysteresis or stability comparison
Choose the scope
Start from the question, not the tool
The method, preparation route and reporting depth depend on what you need to decide.

Common outputs
A result package matched to the decision you need to make
Fields, conditions, processing and file formats are confirmed before work begins.
J-V curve reported with the agreed units, sample reference and measurement conditions.
Voc, Jsc, fill factor and efficiency supplied in a labelled format suitable for direct sample or condition comparison.
Series and shunt resistance indicators provided with the processing basis and quality checks agreed during technical review.
Dark, reverse-scan or stability comparison included when selected in the confirmed reporting scope.
Sample requirements
What to provide before work begins
Provide representative, clearly labelled samples and identify the decision, feature or comparison that matters.
| Suitable sample | Submission requirement | Planning note |
|---|---|---|
| Biological / soft material | Provide fixed, preserved or otherwise stabilised material in the agreed container and medium. | Declare biological hazards and confirm fixation, dehydration, temperature and disposal requirements. |
| Test coupon / specimen | Provide labelled specimens prepared to the agreed geometry, orientation and surface condition. | Confirm the applicable standard, dimensions, loading direction and number of replicates. |
| Device / assembly | Provide a complete labelled device or assembly with drawings, interfaces and operating limits. | Confirm power, connections, operating state, access restrictions and permitted disassembly. |
Objective: state the decision, comparison or acceptance criterion the work must support.
Handling and access: declare hazards, instability, confidentiality, file constraints or special logistics before dispatch or transfer.
Questions and answers
Common planning decisions
Short answers to issues that can change preparation, scope, timing or interpretation.
Is EQE included in Solar I-V?
No. EQE is a separate optical-spectral measurement unless explicitly added.
What is the typical turnaround?
Typical turnaround is 8 working days after sample acceptance and method confirmation.
