LC-SPV-ST-2525 Space PV Module Stability Test System is a turnkey laboratory solution that brings the critical elements of outer-space photovoltaic testing into one compact, highly integrated cabinet: Class A AM0 LED solar simulation, an ultra-wide temperature precision thermal stage, multi-channel electrical measurement, and intelligent automation software. It is designed for advanced space PV technologies such as GaInP₂/GaAs/Ge triple-junction cells and perovskite/silicon tandem cells, supporting device screening, long-term stability evaluation, and qualification-style verification.
Traditional space PV test benches often suffer from scattered instruments, complex cabling, unstable interfaces, and time-consuming setup. LC-SPV-ST-2525 addresses these pain points through a plug-and-play cabinet architecture, improving test repeatability and lab efficiency, while reducing wiring errors and daily maintenance workload.
To simulate the “space environment” in the most essential dimensions, the system combines:
AM0 spectral fidelity (for extraterrestrial irradiance conditions)
Extreme thermal cycling capability (for eclipse / sunlight transition conditions)
High-precision electrical characterization (for I-V / MPPT and degradation tracking)
Automation & data integrity (for long-duration and unattended experiments)
The integrated AM0 LED solar simulator provides Class A performance across spectral match, uniformity, and long-term stability, enabling accurate extraterrestrial PV characterization and aging studies.
AM0 Light Source Performance
| Item | Specification |
|---|---|
| Standard / Spectrum | IEC 60904-9 Edition 3 (AM0) |
| Spectral Match | Class A (350–1800 nm) |
| Irradiance Uniformity | ≤ ±2% (Class A) |
| Long-Term Instability | ≤ ±2% (Class A) |
| Standard Irradiance | 1367 W/m² (1 Solar Constant) |
| Irradiance Adjustment | 100–1500 W/m² (Continuous) |
| Lifetime | > 10,000 hours |
This allows users to perform AM0 efficiency validation, light soaking, and performance drift studies with controlled, repeatable exposure.
The precision photoelectric thermal stage supports extreme temperature simulation comparable to space thermal cycling conditions. Fast ramp rates help shorten test cycles, while high control precision supports reliable parameter comparisons.

| Vacuum Compatibility | 1×10⁻³ Pa (optional vacuum chamber) |
This module enables low-temperature performance mapping, thermal stress screening, and temperature-dependent degradation evaluation for space PV devices.
To increase throughput, the system supports 1–9 independent channels for parallel measurements. Each channel can run I-V scans and MPPT tracking, allowing fast comparison of multiple devices, recipes, or process conditions.
Electrical Measurement (Per Channel)
| Item | Specification |
|---|---|
| Voltage Range | 0 to ±60 V |
| Current Range | 0 to ±5 A |
| Accuracy | ≤ 0.1% F.S. |
| Scan Types | Forward / Reverse / Loop (Hysteresis) |
| MPPT Algorithms | P&O, Incremental Conductance |
For perovskite and tandem devices, hysteresis loop scans help quantify instability effects related to ion migration or transient response, while MPPT tracking records realistic maximum-power behavior over time.
The system integrates an industrial PC and a high-definition display for stable long-term operation, remote control, and visualized data tracking. Automated sequence control supports 24/7 unattended tests with consistent execution and traceable data logs.
