Overview
The CEL-AFS Pulsed Xenon Solar Simulator is an engineered Class A solar simulation system compliant with IEC 60904-9 (AM1.5G spectral irradiance distribution), designed for high-throughput, high-fidelity photovoltaic (PV) device characterization in research and quality control laboratories. It employs a high-stability pulsed xenon arc lamp as its primary radiation source, delivering short-duration (10 ms), spectrally matched illumination to emulate terrestrial sunlight under standard test conditions (STC). The system integrates precision electronic load control, real-time signal acquisition, and hardware-level temperature and irradiance stabilization—enabling accurate measurement of fundamental PV parameters including open-circuit voltage (VOC), short-circuit current (ISC), maximum power point (PMAX), fill factor (FF), power conversion efficiency (η), series resistance (RS), shunt resistance (RSH), reverse bias characteristics, and temperature-dependent performance metrics.
Key Features
- Class A spectral match per IEC 60904-9: AM1.5G spectrum with <±2% non-uniformity over 18 cm × 18 cm test area (CEL-AFS1000 variant extends to 40 cm × 40 cm)
- High temporal stability: Long-term instability (LTI) ≤ ±1%, short-term instability (STI) ≤ ±0.5% — validated per IEC 60904-9 Annex D
- Precision metrology-grade resolution: Voltage ±1 mV, current ±1 mA, temperature ±0.1 °C
- Four-wire Kelvin sensing architecture for contact-resistance-free current–voltage (I–V) measurement
- Automated irradiance compensation and temperature correction algorithms integrated into firmware
- Pneumatically actuated, spring-damped sample clamping mechanism ensures repeatable mechanical contact while minimizing cell fracture risk
- Sub-2-second test cycle time (≥800 measurements/hour), compatible with 156 mm × 156 mm silicon wafers and standard PV substrates
- Optional IR-based non-contact temperature monitoring module reduces thermal drift-induced uncertainty during flash testing
Sample Compatibility & Compliance
The CEL-AFS supports broad-spectrum PV material evaluation, including monocrystalline Si, multicrystalline Si, thin-film technologies (CIGS, CdTe), dye-sensitized solar cells (DSSCs), perovskite devices, and organic photovoltaics (OPVs). All optical and electrical subsystems are calibrated traceably to national metrology institutes (NIM, China); calibration certificates include uncertainty budgets aligned with ISO/IEC 17025 requirements. System compliance includes full adherence to IEC 60904-9:2020, IEC 61215-1 (for reliability pre-screening), and ASTM E927-21 (Standard Specification for Solar Simulation for Photovoltaic Testing). Data integrity meets GLP and GMP documentation standards, with optional 21 CFR Part 11-compliant audit trail functionality available via software upgrade.
Software & Data Management
The embedded control software provides real-time I–V curve plotting, parameter extraction (VOC, ISC, PMAX, FF, η, RS, RSH), batch statistical analysis, and automated grading based on user-defined binning thresholds. Raw data is stored in CSV and HDF5 formats with embedded metadata (timestamp, irradiance, ambient T, lamp pulse count). Export options include PDF reports, Excel-compatible spreadsheets, and direct SQL database ingestion. Version-controlled firmware updates support backward-compatible data migration and extended calibration life management. Remote operation via Ethernet or USB-C enables integration into automated test benches and MES environments.

- Temperature-coefficient determination using synchronized IR thermometry and flash sequencing
- Light-soaking and degradation studies requiring stable, repeatable pulse profiles
- Calibration transfer between reference cells and secondary PV sensors
- Validation of MPPT algorithm performance under transient irradiance conditions
FAQ
What spectral classification does the CEL-AFS achieve per IEC 60904-9?
It meets Class A requirements for spectral match, spatial non-uniformity, and temporal instability.
Is the system suitable for perovskite solar cell testing?
Yes — its low-thermal-load pulsed operation minimizes photo-induced phase segregation and ion migration artifacts common in continuous illumination setups.
Can the CEL-AFS be integrated into an automated production line?
Yes — it supports TTL-triggered operation, Modbus TCP communication, and programmable I/O for synchronization with robotic handlers and conveyors.
Does the system provide traceable calibration documentation?
All units ship with NIM-traceable calibration reports covering spectral irradiance, electrical measurement channels, and temperature sensors.
What is the expected operational lifetime of the xenon lamp module?
Rated for ≥200,000 flashes at nominal energy output; lamp replacement intervals are tracked automatically in system logs.
