Materials Testing

We offer comprehensive testing of your solar cell materials on flexible substrates using industrial-scale processing equipment.

Expertise in Roll-to-Roll Processing and Upscaling Platform
With extensive experience in roll-to-roll processing of flexible organic solar cells, we specialize in optimizing the fabrication of each component in the solar cell stack to maximize performance. Our skilled team, combined with advanced equipment, ensures that your materials undergo testing that facilitates the transition from research to product development, upscaling, and manufacturing. We offer testing on our upscaling platform with flexible substrates, giving you insights into large-scale fabrication while minimizing material consumption.

Minimal Material Requirements & Flexible Testing Options
For upscaling tests, we require only 20-250 mg of active material, depending on the type of studies. You don’t need to disclose your material composition, and we can test multiple material candidates or batches. Testing combinations can be tailored to your specific needs.

Comprehensive Test Preparation, Packaging, and Stability Testing
We provide preparation of both single cells and modules, with encapsulation/packaging options using glass or flexible barrier substrates. In addition, we conduct short accelerated stability tests using concentrated light (100-200 suns) or ISOS-L-2, comparing your material to standard references such as P3HT:PCBM.

Detailed Data Reporting and Support
The resulting data, including solar cell processing parameters, IV-curves, and stability, will be compiled into a comprehensive report that supports your ongoing material research, development, and publication efforts.
