Proven Electroluminescence Technology

With the help of electroluminescence images critical defects such as microcracks and soldering defects are made visible in PV modules . This test improves overall product quality and it optimizes the production process. Electroluminescence testing is a standard in todays module manufacturing and indispensable in production. These systems are usually used before lamination as process control and at the end of the production line as output control for all modules produced.

The requirements for the electroluminescence test have steadily increased in the last years. Today, as example, cycle times of less than 20 sec are required. An automatic evaluation with a high-resolution system is therefore the standard. With more than 300 electroluminescent test systems installed worldwide, MBJ is the market leader in Europe, offering the right solution for all requirements.

Innovative LED technology

LED technology is the future. With our LED flashers a flash duration of up to 200ms can be realized without any problems, which is indispensable for new module concepts. The LEDs are designed for several million measurements, under normal conditions, replacement of the LEDs is no longer necessary. The light intensity and the spectrum also remain stable over the entire product life cycle.

The long life of the LEDs also leads to an immense cost savings compared to a xenon flasher. Another advantage of LED technology is that the individual LEDs or the groups of LEDs can be controlled very precisely. This control allows a nearly constant luminosity over the entire flash duration. The very good stability of the light source leads to an excellent reproducibility of the measurement results.
