Electro Luminescence Tester

Electro Luminescence Testers are not yet required in IEC test procedures. However for performing meaningful analysis of the PV module during its test procedure it is a great advantage to produce EL images after each process step to determine test-induced variations.

This EL test equipment has 6 high-resolution cameras of 180μm/pixel, allowing for detailed analytical work.
In addition it has the capability to recognize areas of change between two measurement events.

This equipment is the heart of the analytical capability of the lab.
