The electroluminescence technology allows the visualization and detection of defects otherwise not visible by the human eye. These defects are e.g. micro cracks, electrically not active areas or grid failures. Micro cracks can progress over time and lead to a significant loss in module power. Electroluminescence inspection systems from MBJ Solutions are available for all steps in the production process of a solar module. Electroluminescence Module Inspection Inline inspection systems for electroluminescence imaging in the production area ... see the hidden defects Why Electroluminescence Imaging? Many defects on a solar module are not visible for the human eye. Electroluminescence imaging makes such invisible defects like micro cracks clearly visible. Using this technology provides the information necessary to improve the product quality and to avoid customer complaints. Defects with no electrical influence today may become critical tomorrow. Thermal stress and mechanical stress induced by weather conditions (storm, snow load) or transportation will lead to power losses of pre-damaged modules. The images below show clearly the influence of cracks on the electrical power of solar modules. Solar cells before and after thermal cycling: The following pictures show why the electroluminescence technology is so important. It is a reliable and cost effective inspection technology to find critical defects like micro cracks. Solar cells before thermal cycling: PMP [Wp] = 7.9 Choosing the right MBJ-Product The following diagram shows the available products for inline electroluminescence inspection. 100µm EL-inline HR 240 MPixel Solar cells after thermal cycling: PMP [Wp] = 6.3 150 cycles from -40°C to 85°C EL-inline HRS 200µm EL-inline eco/EL-inline 60 MPixel EL-inline HS 440µm EL-quickline 11 MPixel 180s 25MW 120s 50MW 90s 75MW 60s 100MW 45s 150MW 30s 200MW The SolarModule EL-quickline The SolarModule EL-quickline with its very simple mechanical design is the entry into inline EL inspection. The multi camera approach allows a very fast EL imaging. The quickline system can be - like the EL-inline products – fully integrated into the production process.

The big advantage of this product family is the automatic image processing software. What makes the MBJ’s EL-inline product family so special? The very simple but also unique mechanical design of the machine combined with a modern high quality software and hardware concept leads to an overall price attractive solution for high end inline electroluminescence inspection. The unique continuous rollers guaranty a perfect glass support even with thinnest glasses. The SolarModule EL-inline eco is the entry model of the EL-inline product family. A resolution of 60 Megapixels allows the semi automatic detection of defects. The premium models SolarModule EL-inline HR and HRS with 240 Megapixels allow the detection of smallest defects and generate best image quality. Flexibility of the EL-inline-family Offering a wide range of options Software license for Fully automated Operation The SolarModule EL-inline-family is designed to be integrated into the module production process, before lamination, after lamination or for framed modules at the end of the line. High resolution cameras provide best image quality and allow automatic defect detection without operator interaction. MBJ can offer a wide range of interfaces for the communication to the up- and downstream conveyor. offline work stations Shunt detection software Diode test Automatic contact unit Automatic cell measurement Automatic barcode scanner EL-inline key features Fast product changeover and safe transport Automatic image processing software Configurable from 60 to 240 Megapixels Continuous carrying rollers for save module transport Automatic contact unit for modules before lamination Integrated cooled NIR-CCD cameras Mechanical interface for integration into production line Long edge leading (LEL) or short edge leading (SEL) Powder coated steel chassis
