// Characterisation of Solar Cells and Modules up to 30 cm x 30 cm

The most important quality test for the thin-film solar cells produced at ZSW is the measurement of the current-voltage characteristic under sun-like illumination. ZSW runs three constant-illumination solar simulators for determining the efficiency of solar cells and modules up to 30 cm x 30 cm in size. The illumination used for the measurements approximates the AM 1.5 global spectrum. The intensity is set to 1000 W/m² and the sample temperature is held at 25 °C for so-called standard testing conditions (STC). The illumination intensity and the sample temperature can be varied for more detailed investigations.


Constant-illumination solar simulators for solar cells and modules up to 10 cm x 10 cm and 30 cm x 30 cm, spectroradiometer for measuring the radiation intensity.

Further Information

We gladly measure current-voltage characteristics for you on solar cells and modules up to 30 cm x 30 cm, also in combination with series tests (e. g. damp heat test, UV test etc.). The contact person will be happy to answer any questions you might have concerning measurements with the solar simulators.
The colleagues of Solab offer you characterisations of modules up to max 3,40 m module diagonal.
