WACOM AM0 Solar Simulator

Overview

The WACOM AM0 Solar Simulator is a high-precision, laboratory-grade irradiation source engineered to replicate extraterrestrial solar spectral irradiance (AM0, 1366 W/m²) with exceptional fidelity for photovoltaic (PV) device characterization and manufacturing validation. Based on a stabilized xenon arc lamp coupled with advanced multi-element optical filtering, collimating lenses, and precision reflective optics, the system delivers spectrally matched illumination compliant with IEC 60904-9 Ed. 3 (2020) Class AAA requirements—specifically achieving spectral match Class A (±5–10% deviation across 300–1200 nm), spatial non-uniformity ≤ ±2%, and temporal stability ≤ ±1% per hour. Designed for R&D labs, PV cell production lines, and third-party calibration facilities, the WACOM platform supports rigorous performance evaluation of silicon, perovskite, multi-junction, and emerging thin-film solar cells—including back-contact and hybrid architectures—under standardized test conditions.

Key Features

• Class AAA-compliant illumination per IEC 60904-9:2020—spectral match (Class A), spatial uniformity (Class A), and temporal stability (Class A)
• Steady-state (DC) operation mode enabling continuous, low-noise irradiation for IV curve tracing, quantum efficiency (QE) mapping, and accelerated lifetime testing
• Optimized optical train comprising fused silica broadband filters, aspheric collimating lenses, and high-reflectivity aluminum-coated mirrors to minimize thermal drift and spectral distortion
• Multiple standard irradiation apertures: 50 mm, 90 mm, 155 mm, 156 mm, 160 mm, 163 mm, 166 mm, 180 mm, 200 mm, 300 mm, and 450 mm—compatible with wafer-level, mini-module, and full-size PV panel testing
• Collimation angle ≤ ±3° ensuring minimal angular dependence in spectral responsivity measurements
• Irradiance tunability from 80 to 140 mW/cm² (0.8–1.4 suns), calibrated traceably to NIST-traceable reference cells

Sample Compatibility & Compliance

The WACOM AM0 Solar Simulator accommodates diverse PV geometries—from single-junction Si wafers to tandem perovskite/Si devices and III-V multi-junction concentrator cells—without optical reconfiguration. Its large-area variants (up to 450 mm aperture) support industrial-scale module qualification. All systems are supplied with factory calibration certificates aligned to ISO/IEC 17025-accredited procedures. The simulator meets critical regulatory benchmarks for PV metrology, including ASTM E927-22 (Standard Specification for Solar Simulation for Photovoltaic Testing), JIS C 8912, and supports GLP-compliant workflows through audit-ready calibration logs and instrument history tracking.

Software & Data Management

WACOM systems integrate with industry-standard PV characterization software suites (e.g., PVIV, LabVIEW-based control modules, and custom Python APIs) for synchronized source control, data acquisition, and automated compliance reporting. Optional firmware enables time-stamped irradiance logging, real-time stability monitoring, and export of raw spectral irradiance datasets in CSV or HDF5 format. For regulated environments, optional 21 CFR Part 11-compliant software packages provide electronic signatures, role-based access control, and immutable audit trails—ensuring full traceability during GMP or ISO 17025 audits.

Applications

• Primary calibration of reference solar cells and pyranometers against AM0 reference spectra
• Efficiency certification of space-grade solar cells (e.g., GaInP/GaAs/Ge triple-junction) per ECSS-E-ST-70-08C
• Process development and yield optimization in high-efficiency PV manufacturing lines
• Spectral response (SR) and external quantum efficiency (EQE) measurements under controlled collimated illumination
• Light soaking and degradation studies requiring stable, repeatable irradiance over extended durations (≥1000 hours)
• Validation of anti-reflective coatings, passivation layers, and bifacial gain factors under AM0-equivalent illumination

FAQ

What standards does the WACOM AM0 Solar Simulator comply with?
