ZOLIX Sirius-SS1600A Large-Area Solar Simulator

Overview

The ZOLIX Sirius-SS1600A is a Class A large-area solar simulator engineered for high-fidelity photovoltaic (PV) device characterization under standardized terrestrial sunlight conditions. It employs a stabilized xenon arc lamp coupled with precision optical filtering and homogenization optics to reproduce the AM1.5G solar spectrum (300–1200 nm) with spectral match compliance per IEC 60904-9:2020. The system delivers uniform irradiance across a 210 mm × 210 mm test plane at intensities up to 1200 mW/cm²—equivalent to 12-suns operation—enabling reliable performance evaluation of full-size solar cells, mini-modules, and emerging thin-film or perovskite PV devices. Its pulsed triggering architecture supports synchronized measurements with external instrumentation such as source measure units (SMUs), quantum efficiency systems, or transient photocurrent analyzers—critical for minimizing thermal loading during short-duration illumination.

Key Features

• Class A spectral match (0.75–1.25) and spatial uniformity (<2%) validated per IEC 60904-9 Annex A
• Temporal irradiance stability <2% over 10 s (short-term) and <3% over 8 h (long-term), monitored via integrated reference photodiode with real-time feedback
• Motorized, programmable shutter with remote TTL/USB control and automatic lifetime logging based on xenon lamp operating hours
• Integrated digital timer and lamp-hour counter with non-volatile memory for GLP-compliant usage tracking
• Downward-facing collimated output optimized for horizontal sample placement and integration into glovebox or environmental chamber workflows
• Robust mechanical architecture with vibration-damped optical bench and air-cooled lamp housing for continuous-duty operation

Sample Compatibility & Compliance

The Sirius-SS1600A accommodates samples ranging from single-junction silicon wafers to multi-terminal tandem devices and flexible organic PV substrates up to 200 mm × 200 mm. Its large active area enables edge-loss minimization in module-level testing and supports ISO 17025-accredited calibration laboratories performing interlaboratory comparisons. The system conforms to IEC 60904-9:2020 (Class A requirements), ASTM E927-22 (Standard Specification for Solar Simulation for Photovoltaic Testing), and supports traceable calibration using NIST-traceable reference cells (e.g., KG5-filtered Si or GaAs). All optical components are certified for UV-stability and thermal load endurance, ensuring repeatability across >5,000 hours of cumulative lamp operation.

Software & Data Management

The simulator integrates seamlessly with third-party instrumentation via standard GPIB, USB-TMC, and Ethernet (LXI-compliant) interfaces. Optional ZOLIX ControlSuite software provides synchronized pulse triggering, irradiance ramping profiles, and automated lamp aging compensation algorithms. Audit trails—including shutter actuation timestamps, irradiance logs, and lamp runtime—are stored in CSV/SQLite format with user-defined metadata fields. For regulated environments, optional 21 CFR Part 11 compliance packages include electronic signatures, role-based access control, and immutable data archiving—supporting GMP/GLP documentation requirements in PV R&D and manufacturing QA/QC labs.

Applications

• Current–voltage (I–V) characterization of PV devices under standard test conditions (STC)
• Quantum efficiency (QE) and external quantum efficiency (EQE) mapping with monochromator-coupled configurations
• Light-soaking studies for perovskite and organic solar cells requiring controlled intensity and spectral fidelity
• Accelerated aging protocols involving repeated light-bias cycling with precise dose control
• Calibration of reference cells and secondary standards in national metrology institutes
• Integration into automated IV testers and solar cell production line sorters

FAQ

Does the Sirius-SS1600A support continuous and pulsed operation modes?

Yes—it operates in both CW (continuous wave) and externally triggered pulsed modes, with minimum pulse width of 10 ms and jitter <100 µs.
Is spectral recalibration required after lamp replacement?

Yes; each xenon lamp exhibits unique spectral drift. ZOLIX provides factory-calibrated spectral correction files and recommends annual full-spectrum validation using a calibrated spectroradiometer.
Can the system be installed inside a nitrogen-filled glovebox?

The optical head is compatible with glovebox integration via custom flange-mounted viewport assemblies; lamp power supply and control electronics must remain external.
What safety interlocks are included?

Hardware-enforced shutter lockout during lamp warm-up/cool-down, overtemperature cutoff, and emergency stop circuit compliant with IEC 61508 SIL2.
Is remote firmware update supported?

Yes—via secure HTTPS interface with version-controlled OTA updates and rollback capability.
