The LC-LED-AAA-300S LED Solar Simulator is a high-precision photovoltaic testing system developed by Lecheng Intelligent, specifically optimized for perovskite solar cell and module characterization. Unlike conventional LED simulators that rely on direct LED emission, the LC-LED-AAA-300S integrates a complete optical shaping system, delivering highly collimated, uniform, and spectrally accurate sunlight simulation.
The system complies with IEC 60904-9 Edition 3 international standards and achieves an overall A+ rating across spectral match, irradiance uniformity, and temporal stability. With a wide spectral coverage from 350 nm to 1200 nm, it precisely matches the full-band absorption characteristics of perovskite photovoltaic materials, from ultraviolet to near-infrared.
Designed for both laboratory research and pilot-line verification, the LC-LED-AAA-300S supports steady-state long-duration testing (24–1000 h) as well as transient pulse testing (>200 ms), making it an ideal platform for efficiency calibration, device tolerance evaluation, and long-term stability studies of perovskite solar devices.
Unlike many competing LED solar simulators that emit divergent light, LC-LED-AAA-300S employs a lens + optical integrator architecture, forming near-parallel sunlight.
Optical Performance Comparison
| Indicator | Conventional LED Simulator | LC-LED-AAA-300S |
|---|---|---|
| Collimation Angle | 30–40° (divergent) | < 5° (collimated) |
| Working Distance | Short | 50 cm |
| Uniform Area | Small / Non-uniform | 300 × 300 mm |
