Materials Testing

We offer to test your solar cell materials on flexible substrate using industrial scaled processing equipment.

Testing of printed solar cells like perovskite

Roll Processing

We know all about roll-to-roll processing of flexible organic solar and we know how to optimize the processing of each component in the solar cell stack in order to gain the best performing device. We have the skilled people, the knowledge, and the setup to test your solar cell materials in a way that will move your research into product development, upscaling, and manufacture.

We can offer to test your materials in our upscaling platform on flexible substrate. This will show what to expect from a large-scale fabrication of your material with a much smaller material consumption.

For an upscaling test, only 20-250 mg of example active material is needed depending on your choice of studies.

We do not need to know your material composition for the tests.

We can test several candidates or batches of materials and several tests can be combined and modified according to specific needs.

We can prepare single cells as well modules and do also provide encapsulation/packaging with either glass or flexible barrier substrate.

We normally include short accelerated stability tests using either concentrated light (100-200 suns) or ISOS-L-2 against a standard reference, such as P3HT:PCBM. The data (solar cell processing parameters, IV-curves and stability) will be compiled into a report that you can use in your further material research and development as well as for publication.

Examples of Standard Tests of Active Layer Materials

Slot-die coating of active layer by tuning the thicknesses, web speed, flow of solution, donor:acceptor ratio, solvent and/or coating temperature.
Single cells with active area of 1-7 cm2
Modules with 2-8 cells with an active area of 2-50 cm2
Encapsulation with glass and/or flexible barrier foils
Stability tests according to ISOS recommendations more info

(The active material being either acceptor, donor or blend materials. All devices and modules are prepared with inverted geometry on our high performing flexible substrate using slot-die coating under atmospheric conditions.)
