ARKEO SOAKER XL
Large-area illumination
for stability and aging workflows.
ARKEO Soaker XL is the large-area light-soaker platform developed for reproducible exposure of photovoltaic and optoelectronic devices. It is designed for long-duration tests, accelerated aging protocols and controlled spectral studies where area, homogeneity and stability all matter.

Why it is used
The platform provides a controlled light environment for experiments where the sample must stay under illumination for hours, days or longer. It is suitable for device aging, reliability comparison, ISOS-style workflows and repeatable exposure of broader sample areas.
- Large-area exposure without moving the sample during the test.
- Independent spectral channels for tuning and calibration.
- Designed for repeatable long-term operation with software supervision.
- Useful for both research studies and pre-industrial validation workflows.
Calibration and verification tools are part of the workflow. The attached examples show spectral matching against AM1.5G, homogeneity mapping and the dedicated control software used to review bins, total irradiance and simulator classification.
